Suspension for injection in a pre-filled pen (OptiSet or SoloStar), cartridge or vial.
After resuspension, milky-white suspension.
4. Clinical Particulars
4.1 Therapeutic Indications
Diabetes mellitus where treatment with insulin is required.
4.2 Posology And Method Of Administration
The desired blood glucose levels, the insulin preparations to be used and the insulin dose regimen (doses and timings) must be determined individually and adjusted to suit the patient's diet, physical activity and life-style.
Daily doses and timing of administration
There are no fixed rules for insulin dose regimen. However, the average insulin requirement is often 0.5 to 1.0 IU per kg body weight per day. The basal metabolic requirement is 40% to 60% of the total daily requirement. Insuman Comb 15 and Comb 25 are injected subcutaneously 30 to 45 minutes before a meal. Insuman Comb 50 is injected subcutaneously 20 to 30 minutes before a meal.
OptiSet delivers insulin in increments of 2 IU up to a maximum single dose of 40 IU. SoloStar delivers insulin in doses from 1 to 80 units in steps of 1 unit. Each pen contains multiple doses.
Secondary dose adjustment
Improved metabolic control may result in increased insulin sensitivity, leading to a reduced insulin requirement. Dose adjustment may also be required, for example, if
- the patient's weight changes,
- the patient's life-style changes,
- other circumstances arise that may promote an increased susceptibility to hypo- or hyperglycaemia (see section 4.4).
Use in specific patient groups
In patients with hepatic or renal impairment as well as in the elderly, insulin requirements may be diminished (see section 4.4).
Administration
Insuman Comb 25 vials: Insuman Comb 25 contains 100 IU of insulin per ml suspension. Only injection syringes designed for this strength of insulin (100 IU per ml) are to be used. The injection syringes must not contain any other medicinal product or residue (e.g. traces of heparin).
Insuman Comb 15, 25 and 50 are administered subcutaneously. Insuman Comb 15, 25 and 50 must never be injected intravenously.
Insulin absorption and hence the blood-glucose-lowering effect of a dose may vary from one injection area to another (e.g. the abdominal wall compared with the thigh). Injection sites within an injection area must be rotated from one injection to the next.
Before using OptiSet or SoloStar, the Instructions for Use included in the Package Leaflet must be read carefully.
For further details on handling, see section 6.6.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients.
4.4 Special Warnings And Precautions For Use
Patients hypersensitive to Insuman Comb 15, 25 or 50 for whom no better tolerated preparation is available must only continue treatment under close medical supervision and – where necessary – in conjunction with anti-allergic treatment.
In patients with an allergy to animal insulin intradermal skin testing is recommended prior to a transfer to Insuman Comb 15, 25 or 50, since they may experience immunological cross-reactions.
In patients with renal impairment, insulin requirements may be diminished due to reduced insulin metabolism. In the elderly, progressive deterioration of renal function may lead to a steady decrease in insulin requirements.
In patients with severe hepatic impairment, insulin requirements may be diminished due to reduced capacity for gluconeogenesis and reduced insulin metabolism.
In case of insufficient glucose control or a tendency to hyper- or hypoglycaemic episodes, the patient's adherence to the prescribed treatment regimen, injection sites and proper injection technique and all other relevant factors must be reviewed before dose adjustment is considered.
Transfer to Insuman Comb 15, 25 or 50
Transferring a patient to another type or brand of insulin should be done under strict medical supervision. Changes in strength, brand (manufacturer), type (regular, NPH, lente, long-acting,etc.), origin (animal, human, human insulin analogue) and/or method of manufacture may result in the need for a change in dosage.
The need to adjust (e.g. reduce) the dose may become evident immediately after transfer. Alternatively, it may emerge gradually over a period of several weeks.
Following transfer from an animal insulin to human insulin, dose regimen reduction may be required in particular in patients who
- were previously already controlled on rather low blood glucose levels,
- have a tendency to hypoglycaemia,
- previously required high insulin doses due to the presence of insulin antibodies.
Close metabolic monitoring is recommended during the transition and in the initial weeks thereafter. In patients who require high insulin doses because of the presence of insulin antibodies, transfer under medical supervision in a hospital or similar setting must be considered.
Hypoglycaemia
Hypoglycaemia may occur if the insulin dose is too high in relation to the insulin requirement.
Particular caution should be exercised, and intensified blood glucose monitoring is advisable in patients in whom hypoglycaemic episodes might be of particular clinical relevance, such as in patients with significant stenoses of the coronary arteries or of the blood vessels supplying the brain (risk of cardiac or cerebral complications of hypoglycaemia) as well as in patients with proliferative retinopathy, particularly if not treated with photocoagulation (risk of transient amaurosis following hypoglycaemia).
Patients should be aware of circumstances where warning symptoms of hypoglycaemia are diminished. The warning symptoms of hypoglycaemia may be changed, be less pronounced or be absent in certain risk groups. These include patients:
- in whom glycaemic control is markedly improved,
- in whom hypoglycaemia develops gradually,
- who are elderly,
- after transfer from animal insulin to human insulin,
- in whom an autonomic neuropathy is present,
- with a long history of diabetes,
- suffering from a psychiatric illness,
- receiving concurrent treatment with certain other medicinal products (see section 4.5).
Such situations may result in severe hypoglycaemia (and possibly loss of consciousness) prior to the patient's awareness of hypoglycaemia.
If normal or decreased values for glycated haemoglobin are noted, the possibility of recurrent, unrecognised (especially nocturnal) episodes of hypoglycaemia must be considered.
Adherence of the patient to the dose regimen and dietary regimen, correct insulin administration and awareness of hypoglycaemia symptoms are essential to reduce the risk of hypoglycaemia. Factors increasing the susceptibility to hypoglycaemia require particularly close monitoring and may necessitate dose adjustment. These include:
- change in the injection area,
- improved insulin sensitivity (e.g. by removal of stress factors),
- unaccustomed, increased or prolonged physical activity,
- intercurrent illness (e.g. vomiting, diarrhoea),
- inadequate food intake,
- missed meals,
- alcohol consumption,
- certain uncompensated endocrine disorders (e.g. in hypothyroidism and in anterior pituitary or adrenocortical insufficiency),
- concomitant treatment with certain other medicinal products.
Intercurrent illness
Intercurrent illness requires intensified metabolic monitoring. In many cases, urine tests for ketones are indicated, and often it is necessary to adjust the insulin dose. The insulin requirement is often increased. Patients with type 1 diabetes must continue to consume at least a small amount of carbohydrates on a regular basis, even if they are able to eat only little or no food, or are vomiting etc. and they must never omit insulin entirely.
Medication errors
Medication errors have been reported in which other Insuman formulations or other insulins have been accidentally administered. Insulin label must always be checked before each injection to avoid medication errors between insulin human and other insulins.
Combination of Insuman with pioglitazone
Cases of cardiac failure have been reported when pioglitazone was used in combination with insulin, especially in patients with risk factors for development of cardiac heart failure. This should be kept in mind if treatment with the combination of pioglitazone and Insuman is considered. If the combination is used, patients should be observed for signs and symptoms of heart failure, weight gain and oedema. Pioglitazone should be discontinued if any deterioration in cardiac symptoms occurs.
Pens to be used with Insuman Comb 15, 25 and 50 cartridges
The Insuman Comb 15, 25 and 50 cartridges should only be used with the following pens: OptiPen, ClikSTAR and Autopen 24 and should not be used with any other reusable pen as the dosing accuracy has only been established with the listed pens.
Handling of the pen
Before using OptiSet or SoloStar, the Instructions for Use included in the Package Leaflet must be read carefully. OptiSet and SoloStar have to be used as recommended in these Instructions for Use (see section 6.6).
4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction
A number of substances affect glucose metabolism and may require dose adjustment of human insulin.
Substances that may enhance the blood-glucose-lowering effect and increase susceptibility to hypoglycaemia include oral antidiabetic agents, angiotensin converting enzyme (ACE) inhibitors, disopyramide, fibrates, fluoxetine, monoamine oxidase (MAO) inhibitors, pentoxifylline, propoxyphene, salicylates and sulphonamide antibiotics.
Substances that may reduce the blood-glucose-lowering effect include corticosteroids, danazol, diazoxide, diuretics, glucagon, isoniazid, oestrogens and progestogens (e.g. in oral contraceptives), phenothiazine derivatives, somatropin, sympathomimetic agents (e.g. epinephrine [adrenaline], salbutamol, terbutaline), thyroid hormones, protease inhibitors and atypical antipsychotic medicinal products (e.g. olanzapine and clozapine).
Beta-blockers, clonidine, lithium salts or alcohol may either potentiate or weaken the blood-glucose-lowering effect of insulin. Pentamidine may cause hypoglycaemia which may sometimes be followed by hyperglycaemia.
In addition, under the influence of sympatholytic medicinal products such as beta-blockers, clonidine, guanethidine and reserpine, the signs of adrenergic counter-regulation may be reduced or absent.
4.6 Pregnancy And Lactation
Pregnancy
For insulin human, no clinical data on exposed pregnancies are available. Insulin does not cross the placental barrier. Caution should be exercised when prescribing to pregnant women.
It is essential for patients with pre-existing or gestational diabetes to maintain good metabolic control throughout pregnancy. Insulin requirements may decrease during the first trimester and generally increase during the second and third trimesters. Immediately after delivery, insulin requirements decline rapidly (increased risk of hypoglycaemia). Careful monitoring of glucose control is essential.
Lactation
No effects on the suckling child are anticipated. Insuman Comb 15, 25 and 50 can be used during breast-feeding.
Lactating women may require adjustments in insulin dose and diet.
4.7 Effects On Ability To Drive And Use Machines
The patient's ability to concentrate and react may be impaired as a result of hypoglycaemia or hyperglycaemia or, for example, as a result of visual impairment. This may constitute a risk in situations where these abilities are of special importance (e.g. driving a car or operating machines).
Patients should be advised to take precautions to avoid hypoglycaemia whilst driving. This is particularly important in those who have reduced or absent awareness of the warning symptoms of hypoglycaemia or have frequent episodes of hypoglycaemia. It should be considered whether it is advisable to drive or operate machines in these circumstances.
4.8 Undesirable Effects
Hypoglycaemia, in general the most frequent undesirable effect of insulin therapy, may occur if the insulin dose is too high in relation to the insulin requirement. In clinical trials and during marketed use, the frequency varies with patient population and dose regimens. Therefore, no specific frequency can be presented.
Severe hypoglycaemic attacks, especially if recurrent, may lead to neurological damage. Prolonged or severe hypoglycaemic episodes may be life-threatening.
In many patients, the signs and symptoms of neuroglycopenia are preceded by signs of adrenergic counter-regulation. Generally, the greater and more rapid the decline in blood glucose, the more marked is the phenomenon of counter-regulation and its symptoms.
The following related adverse reactions from clinical investigations are listed below by system organ class and in order of decreasing incidence: very common (
Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.
Immune system disorders
Uncommon: shock
Not known: immediate type allergic reactions (hypotension, angioneurotic oedema, bronchospasm, generalised skin reactions), anti-insulin antibodies
Immediate type allergic reactions to insulin or to the excipients may be life-threatening.
Insulin administration may cause anti-insulin antibodies to form. In rare cases, the presence of such anti-insulin antibodies may necessitate adjustment of the insulin dose in order to correct a tendency to hyper- or hypoglycaemia.
Metabolism and nutrition disorders
Common: oedema
Not known: sodium retention
Insulin may cause sodium retention and oedema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
Eyes disorders
Not known: proliferative retinopathy, diabetic retinopathy, visual impairment
A marked change in glycaemic control may cause temporary visual impairment, due to temporary alteration in the turgidity and refractive index of the lens.
Long-term improved glycaemic control decreases the risk of progression of diabetic retinopathy. However, intensification of insulin therapy with abrupt improvement in glycaemic control may be associated with temporary worsening of diabetic retinopathy.
Skin and subcutaneous tissue disorders
Not known: lipodystrophy
As with any insulin therapy, lipodystrophy may occur at the injection site and delay local insulin absorption. Continuous rotation of the injection site within the given injection area may help to reduce or prevent these reactions.
General disorders and administration site conditions
Common: injection site reactions
Uncommon: injection site urticaria
Not known: injection site inflammation, injection site swelling, injection site pain, injection site pruritus, injection site erythema.
Most minor reactions to insulins at the injection site usually resolve in a few days to a few weeks.
4.9 Overdose
Symptoms
Insulin overdose may lead to severe and sometimes long-term and life-threatening hypoglycaemia.
Management
Mild episodes of hypoglycaemia can usually be treated with oral carbohydrates. Adjustments in dose regimen of the medicinal product, meal patterns, or physical activity may be needed.
More severe episodes with coma, seizure, or neurologic impairment may be treated with intramuscular/subcutaneous glucagon or concentrated intravenous glucose. Sustained carbohydrate intake and observation may be necessary because hypoglycaemia may recur after apparent clinical recovery.
5. Pharmacological Properties
5.1 Pharmacodynamic Properties
Pharmacotherapeutic group: Insulins and analogues for injection, intermediate-acting combined with fast-acting, ATC Code: A10AD01.
Mode of action
Insulin
- lowers blood glucose and promotes anabolic effects as well as decreasing catabolic effects,
- increases the transport of glucose into cells as well as the formation of glycogen in the muscles and the liver, and improves pyruvate utilisation. It inhibits glycogenolysis and gluconeogenesis,
- increases lipogenesis in the liver and adipose tissue and inhibits lipolysis,
- promotes the uptake of amino acids into cells and promotes protein synthesis,
- enhances the uptake of potassium into cells.
Pharmacodynamic characteristics
Insuman Comb 15 (a biphasic isophane insulin suspension with 15% dissolved insulin) is an insulin with gradual onset and long duration of action. Following subcutaneous injection, onset of action is within 30 to 60 minutes, the phase of maximum action is between 2 and 4 hours after injection and the duration of action is 11 to 20 hours.
Insuman Comb 25 (a biphasic isophane insulin suspension with 25% dissolved insulin) is an insulin with gradual onset and long duration of action. Following subcutaneous injection, onset of action is within 30 to 60 minutes, the phase of maximum action is between 2 and 4 hours after injection and the duration of action is 12 to 19 hours.
Insuman Comb 50 (a biphasic isophane insulin suspension with 50% dissolved insulin) is an insulin with rapid onset and moderately long duration of action. Following subcutaneous injection, onset of action is within 30 minutes, the phase of maximum action is between 1.5 and 4 hours after injection and the duration of action is 12 to 16 hours.
5.2 Pharmacokinetic Properties
In healthy subjects, the serum half-life of insulin is approximately 4 to 6 minutes. It is longer in patients with severe renal insufficiency. However, it must be noted that the pharmacokinetics of insulin do not reflect its metabolic action.
5.3 Preclinical Safety Data
The acute toxicity was studied following subcutaneous administration in rats. No evidence of toxic effects was found. Studies of pharmacodynamic effects following subcutaneous administration in rabbits and dogs revealed the expected hypoglycaemic reactions.

6.6 Special Precautions For Disposal And Other Handling
The Insuman Comb 15, 25 and 50 cartridges are to be used in conjunction with OptiPen, ClikSTAR or Autopen 24 (see section 4.4).
The pen should be used as recommended in the information provided by the device manufacturer.
OptiSet and SoloStar pens:
Before first use, Insuman Comb 15, 25 and 50 must be kept at room temperature for 1 to 2 hours and then resuspended to check the contents. This is best done by gently tilting the pen back and forth (at least ten times). Each cartridge contains three small metal balls to facilitate quick and thorough mixing of the contents. Later on, the insulin must be resuspended again prior to each injection.
After resuspension, the fluid must have a uniformly milky appearance. Insuman Comb 15, 25 and 50 must not be used if this cannot be achieved, i.e. if the suspension remains clear, for example, or if clumps, particles or flocculation appear in the insulin or stick to the wall or bottom of the cartridge. These changes sometimes give the cartridge a frosted appearance. In such cases, a new pen yielding a uniform suspension must be used. It is also necessary to change to a new pen if the insulin requirement changes substantially.
Empty pens must never be re-used and must be properly discarded.
To prevent the possible transmission of disease, each pen must be used by one patient only.
As with all insulin preparations, Insuman Comb 15, 25 and 50 must not be mixed with solutions containing reducing agents such as thioles and sulphites. It must also be remembered that
- insulin protamine crystals dissolve in an acid pH range,
- he soluble insulin part precipitates out at a pH of approximately 4.5 to 6.5.
Insulin label must always be checked before each injection to avoid medication errors between insulin human and other insulins (see section 4.4).
Mixing of insulins
Insuman Comb 15, 25 and 50 must not be mixed with any other insulin or with insulin analogues.
Any unused product or waste material should be disposed of in accordance with local requirements.
OptiSet pen:
Handling of the pen The patient should be advised to read the instructions for use included in the package leaflet carefully before using OptiSet.
Schematic diagram of the pen
Important information for use of OptiSet:
• A new needle must always be attached before each use. Only needles that are compatible for use with OptiSet must be used.
• A safety test must always be performed before each injection.
• If a new OptiSet is used the initial safety test must be done with the 8 units preset by the manufacturer.
• The dosage selector can only be turned in one direction.
• The dosage selector (change the dose) must never be turned after injection button has been pulled out.
• This pen is only for the patients use. It must not be shared with anyone else.
• If the injection is given by another person, special caution must be taken by this person to avoid accidental needle injury and transmission of infection.
• OptiSet must never be used if it is damaged or if the patient is not sure if it is working properly.
• The patient must always have a spare OptiSet available in case the OptiSet is lost or damaged.
Storage Instructions
Please check section 6.4 of this SPC for instructions on how to store OptiSet.
If OptiSet is in cool storage, it should be taken out 1 to 2 hours before injection to allow it to warm up. Cold insulin is more painful to inject.
The used OptiSet must be discarded as required by your local authorities.
Maintenance
OptiSet has to be protected from dust and dirt.
The outside of the OptiSet can be cleaned by wiping it with a damp cloth.
The pen must not be soaked, washed or lubricated as this may damage it.
OptiSet is designed to work accurately and safely. It should be handled with care. The patient should avoid situations where OptiSet may be damaged. If the patient is concerned that the OptiSet may be damaged, he must use a new one.
Step 1. Check and mix the Insulin
After removing the pen cap, the label on the pen and the insulin reservoir should be checked to make sure it contains the correct insulin.
The insulin should be mixed by turning OptiSet slowly up and down at least 10 times.
The appearance of the insulin should be checked: the insulin suspension must have an evenly milky-white appearance.
Step 2. Attach the needle
The needle should be carefully attached straight onto the pen.
Step 3. Perform a safety test
Prior to each injection a safety test has to be performed.
For a new and unused OptiSet, a dose of 8 units is already preset by the manufacturer for the first safety test.
In-use OptiSet, a dose of 2 units has to be selected by turning the dosage selector forward till the dose arrow points to 2. The dosage selector will only turn in one direction.
The injection button should be pulled out completely in order to load the dose. The dosage selector must never be turned after the injection button has been pulled out.
The outer and inner needle caps should be removed. The outer cap should be kept to remove the used needle.
While holding the pen with the needle pointing upwards, the insulin reservoir should be tapped with the finger so that any air bubbles rise up towards the needle.
Then the injection button should be pressed all the way in.
If insulin has been expelled through the needle tip, then the pen and the needle are working properly. If no insulin appears at the needle tip, step 3 should be repeated two more times until insulin appears at the needle tip. If still no insulin comes out, change the needle, as it might be blocked and try again. If no insulin comes out after changing the needle, the OptiSet may be damaged. This OptiSet must not be used.
Step 4. Select the dose
The dose can be set in steps of 2 units, from a minimum of 2 units to a maximum of 40 units. If a dose greater than 40 units is required, it should be given as two or more injections.
The patient must always check if he has enough insulin for the dose.
The residual insulin scale on the transparent insulin reservoir shows approximately how much insulin remains in the OptiSet. This scale must not be used to set the insulin dose.
If the black plunger is at the beginning of the coloured bar, then there are approximately 40 units of insulin available.
If the black plunger is at the end of the coloured bar, then there are approximately 20 units of insulin available.
The dosage selector should be turned forward until the dose arrow points to the required dose.
Step 5. Load the dose
The injection button should be pulled out as far as it will go in order to load the pen.
The patient must check if the selected dose is fully loaded. The injection button only goes out as far as the amount of insulin that is left in the reservoir.
The injection button allows checking the actual loaded dose. The injection button must be held out under tension during this check. The last thick line visible on the injection button shows the amount of insulin loaded. When the injection button is held out only the top part of this thick line can be seen.
Step 6. Inject the dose
The patient should be informed on the injection technique by his health care professional. The needle should be inserted into the skin.
The injection button should be pressed all the way in. A clicking sound can be heard, which will stop when the injection button has been pressed in completely. Then the injection button should be held down 10 seconds before withdrawing the needle from the skin. This ensures that the full dose of insulin has been delivered.
Step 7. Remove and discard the needle
The needle should be removed after each injection and discarded. This helps prevent contamination and/or infection as well as entry of air into the insulin reservoir and leakage of insulin, which can cause inaccurate dosing. Needles must not be re-used.
The pen cap should be replaced on the pen.
SoloStar pen:
Before first use, Insuman Comb 25 must be kept at room temperature for 1 to 2 hours and then resuspended to check the contents. This is best done by gently tilting the pen back and forth (at least ten times). Each cartridge contains three small metal balls to facilitate quick and thorough mixing of the contents. Later on, the insulin must be resuspended again prior to each injection.
After resuspension, the fluid must have a uniformly milky appearance. Insuman Comb 25 must not be used if this cannot be achieved, i.e. if the suspension remains clear, for example, or if clumps, particles or flocculation appear in the insulin or stick to the wall or bottom of the cartridge. These changes sometimes give the cartridge a frosted appearance. In such cases, a new pen yielding a uniform suspension must be used. It is also necessary to change to a new pen if the insulin requirement changes substantially.
Empty pens must never be re-used and must be properly discarded.
To prevent the possible transmission of disease, each pen must be used by one patient only.
As with all insulin preparations, Insuman Comb 25 must not be mixed with solutions containing reducing agents such as thioles and sulphites. It must also be remembered that
- insulin protamine crystals dissolve in an acid pH range,
- he soluble insulin part precipitates out at a pH of approximately 4.5 to 6.5.
Mixing of insulins
Insuman Comb 25 must not be mixed with any other insulin or with insulin analogues.
Any unused product or waste material should be disposed of in accordance with local requirements.
Handling of the pen
The patient should be advised to read the instructions for use included in the package leaflet carefully before using SoloStar.
Schematic diagram of the pen
Important information for use of SoloStar:
• Before each use, a new needle must always be carefully attached and a safety test must be performed. Only use needles that are compatible for use with SoloStar.
• Special caution must be taken to avoid accidental needle injury and transmission of infection.
• SoloStar must never be used if it is damaged or if the patient is not sure if it is working properly.
• The patient must always have a spare SoloStar available in case the SoloStar is lost or damaged.
Storage Instructions
Please check section 6.4 for instructions on how to store SoloStar.
If SoloStar is in cool storage, it should be taken out 1 to 2 hours before injection to allow it to warm up. Cold insulin is more painful to inject.
The used SoloStar must be discarded as required by your local authorities.
Maintenance
SoloStar has to be protected from dust and dirt.
The outside of the SoloStar can be cleaned by wiping it with a damp cloth.
The pen must not be soaked, washed or lubricated as this may damage it.
SoloStar is designed to work accurately and safely. It should be handled with care. The patient should avoid situations where SoloStar may be damaged. If the patient is concerned that the SoloStar may be damaged, he must use a new one.
Step 1. Check the insulin
The label on the pen should be checked to make sure it contains the correct insulin. Insuman SoloStar is white with a colour on the injection button. The injection button colour will vary based on the formulation of Insuman insulin used.
After removing the pen cap, the appearance of the insulin should also be checked:
• The insulin solution (Insuman Rapid) must be clear, colourless, with no solid particles visible, and must have a water-like consistency. Do not use this SoloStar if insulin is cloudy, coloured or has particles.
• The insulin suspensions (Insuman Basal or Insuman mixtures) should be mixed by turning SoloStar up and down at least 10 times to resuspend the insulin. The pen should be turned gently to avoid foaming in the cartridge. After mixing, the insulin suspensions must have an evenly milky-white appearance.
Step 2. Attach the needle
Only needles that are compatible for use with SoloStar should be used.
A new sterile needle will be always used for each injection. After removing the cap, the needle should be carefully attached straight onto the pen.
Step 3. Perform a safety test
Prior to each injection, a safety test has to be performed to ensure that pen and needle work properly and to remove air bubbles.
A dose of 2 units has to be selected.
The outer and inner needle caps should be removed.
While holding the pen with the needle pointing upwards, the insulin reservoir should be tapped gently with the finger so that any air bubbles rise up towards the needle.
Then the injection button should be pressed in completely.
If insulin has been expelled through the needle tip, then the pen and the needle are working properly. If no insulin appears at the needle tip, step 3 should be repeated until insulin appears at the needle tip.
Step 4. Select the dose
The dose can be set in steps of 1 unit, from a minimum of 1 unit to a maximum of 80 units. If a dose greater than 80 units is required, it should be given as two or more injections.
The dose window must show “0” following the safety test. The dose can then be selected.
Step 5. Inject the dose
The patient should be informed on the injection technique by his health care professional.
The needle should be inserted into the skin.
The injection button should be pressed in completely. Then the injection button should be held down 10 seconds before withdrawing the needle. This ensures that the full dose of insulin has been injected.
Step 6. Remove and discard the needle
The needle should always be removed after each injection and discarded. This helps prevent contamination and/or infection, entry of air into the insulin reservoir and leakage of insulin. Needles must not be re-used.
Special caution must be taken when removing and disposing of the needle. Recommended safety measures for removal and disposal of needles must be followed (e.g. a one handed capping technique) in order to reduce the risk of accidental needle injury and transmission of infectious diseases.
The pen cap should be replaced on the pen.

The cartridges are to be used in conjunction with an insulin pen such as OptiPen and other pens suitable for Insuman cartridges and as recommended in the information provided by the device manufacturer.
The manufacturer's instructions for using the pen must be followed carefully for loading the cartridge, attaching the injection needle, and administering the insulin injection.
If the insulin pen is damaged or not working properly (due to mechanical defects) it has to be discarded, and a new insulin pen has to be used.
If the pen malfunctions (see instructions for using the pen), the suspension may be drawn from the cartridge into an injection syringe (suitable for an insulin with 100 IU/ml) and injected.
Before insertion into the pen, Insuman Comb 15, 25 and 50 must be kept at room temperature for 1 to 2 hours and then resuspended to check the contents. This is best done by gently tilting the cartridge back and forth (at least ten times). Each cartridge contains three small metal balls to facilitate quick and thorough mixing of the contents.
Later on, when the cartridge has been inserted into the pen, the insulin must be resuspended again prior to each injection. This is best done by gently tilting the pen back and forth (at least ten times).
After resuspension, the fluid must have a uniformly milky appearance. Insuman Comb 15, 25 and 50 must not be used if this cannot be achieved, i.e. if the suspension remains clear, for example, or if clumps, particles or flocculation appear in the insulin or stick to the wall or bottom of the cartridge. These changes sometimes give the cartridge a frosted appearance. In such cases, a new cartridge yielding a uniform suspension must be used. It is also necessary to change to a new cartridge if the insulin requirement changes substantially.
Air bubbles must be removed from the cartridge before injection (see instructions for using the pen). Empty cartridges must not be refilled.
As with all insulin preparations, Insuman Comb 15, 25 and 50 must not be mixed with solutions containing reducing agents such as thioles and sulphites. It must also be remembered that
- insulin protamine crystals dissolve in an acid pH range,
- the soluble insulin part precipitates out at a pH of approximately 4.5 to 6.5.
Insulin label must always be checked before each injection to avoid medication errors between insulin human and other insulins (see section 4.4).
Mixing of insulins
Insuman Comb 15, 25 and 50 may be mixed with all Sanofi-Aventis human insulins, but NOT with those designed specifically for use in insulin pumps. Insuman Comb 15, 25 and 50 must also NOT be mixed with insulins of animal origin or with insulin analogues.
Insuman Comb 15, 25 and 50 cartridges are not designed to allow any other insulin to be mixed in the cartridge.
Any unused product or waste material should be disposed of in accordance with local requirements.
Vials:
Before withdrawing insulin from the vial for the first time, remove the plastic protective cap.
Immediately before withdrawal from the vial into the injection syringe, the insulin must be resuspended. This is best done by rolling the vial at an oblique angle between the palms of the hands. Do not shake the vial vigorously as this may lead to changes in the suspension (giving the vial a frosted appearance; see below) and cause frothing. Froth may interfere with the correct measurement of the dose.
After resuspension, the fluid must have a uniformly milky appearance. Insuman Comb 25 must not be used if this cannot be achieved, i.e. if the suspension remains clear, for example, or if clumps, particles or flocculation appear in the insulin or stick to the wall or bottom of the vial. These changes sometimes give the vial a frosted appearance. In such cases, a new vial yielding a uniform suspension must be used. It is also necessary to change to a new vial if the insulin requirement changes substantially.

Mixing of insulins
Insuman Comb 25 may be mixed with all Sanofi-Aventis human insulins, but NOT with those designed specifically for use in insulin pumps. Insuman Comb 25 must also NOT be mixed with insulins of animal origin or with insulin analogues.
If two different insulins have to be drawn into one single injection syringe, it is recommended that the shorter-acting insulin be drawn first to prevent contamination of the vial by the longer-acting preparation. It is advisable to inject immediately after mixing. Insulins of different concentration (e.g. 100 IU per ml and 40 IU per ml) must not be mixed.
Any unused product or waste material should be disposed of in accordance with local requirements.
