Humalog 100 U/ml KwikPen, solution for injection
General description
Humalog KwikPen is a sterile, clear, colourless, aqueous solution.
Qualitative and quantitative composition
One ml contains 100U (equivalent to 3.5mg) insulin lispro (recombinant DNA origin produced in E.coli).
Each container includes 3ml equivalent to 300U insulin lispro.
For a full list of excipients, see section 6.1.
Solution for injection.
Therapeutic indications
For the treatment of adults and children with diabetes mellitus who require insulin for the maintenance of
normal glucose homeostasis. Humalog KwikPen is also indicated for the initial stabilisation of diabetes
Posology and method of administration
The dosage should be determined by the physician, according to the requirement of the patient.
Humalog may be given shortly before meals. When necessary Humalog can be given soon after meals.
Humalog preparations should be given by subcutaneous injection or by continuous subcutaneous infusion
pump (see section 4.2) and may, although not recommended, also be given by intramuscular injection. If
necessary, Humalog may also be administered intravenously, for example; for the control of blood
glucose levels during ketoacidosis, acute illnesses or during intra and post operative periods.
Subcutaneous administration should be in the upper arms, thighs, buttocks, or abdomen. Use of injection
sites should be rotated so that the same site is not used more than approximately once a month.
When administered subcutaneously care should be taken when injecting Humalog KwikPen to ensure that
a blood vessel has not been entered. After injection, the site of injection should not be massaged. Patients
must be educated to use the proper injection techniques.
Humalog KwikPen takes effect rapidly and has a shorter duration of activity (2 to 5 hours) given
subcutaneously as compared with regular insulin. This rapid onset of activity allows a Humalog injection
(or, in the case of administration by continuous subcutaneous infusion, a Humalog bolus) to be given very
close to mealtime. The time course of action of any insulin may vary considerably in different individuals
or at different times in the same individual. The faster onset of action compared to soluble human insulin
is maintained regardless of injection site. As with all insulin preparations, the duration of action of
Humalog KwikPen is dependent on dose, site of injection, blood supply, temperature, and physical
Humalog can be used in conjunction with a longer-acting human insulin or oral sulphonylurea agents, on
the advice of a physician.
Use of Humalog in an insulin infusion pump:
Only certain CE-marked insulin infusion pumps may be used to infuse insulin lispro. Before infusing
insulin lispro, the manufacturers instructions should be studied to ascertain the suitability or otherwise for
the particular pump. Read and follow the instructions that accompany the infusion pump. Use the correct
reservoir and catheter for the pump. Change the infusion set every 48 hours. Use aseptic technique when
inserting the infusion set. In the event of a hypoglycaemic episode, the infusion should be stopped until
the episode is resolved. If repeated or severe low blood glucose levels occur, notify your health care
professional and consider the need to reduce or stop your insulin infusion. A pump malfunction or
obstruction of the infusion set can result in a rapid rise in glucose levels. If an interruption to insulin flow
is suspected, follow the instructions in the product literature and if appropriate, notify your health care
professional. When used with an insulin infusion pump, Humalog should not be mixed with any other
Intravenous administration of insulin:
Intravenous injection of insulin lispro should be carried out following normal clinical practise for
intravenous injections, for example by an intravenous bolus or by an infusion system. Frequent
monitoring of the blood glucose levels is required.
Infusion systems at concentrations from 0.1U/ml to 1.0U/ml insulin lispro in 0.9% sodium chloride or 5%
dextrose are stable at room temperature for 48 hours. It is recommended that the system is primed before
starting the infusion to the patient.
Hypersensitivity to insulin lispro or to any of the excipients.
Special warnings and precautions for use
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, etc.), species (animal, human,
human insulin analogue), and/or method of manufacture (recombinant DNA versus animal-source insulin)
may result in the need for a change in dosage. For fast-acting insulins, any patient also on basal insulin
must optimise dosage of both insulins to obtain glucose control across the whole day, particularly
nocturnal/fasting glucose control.
Conditions which may make the early warning symptoms of hypoglycaemia different or less pronounced
include long duration of diabetes, intensified insulin therapy, diabetic nerve disease or medications such
as beta-blockers.
A few patients who have experienced hypoglycaemic reactions after transfer from animal-source insulin
to human insulin have reported that the early warning symptoms of hypoglycaemia were less pronounced
or different from those experienced with their previous insulin. Uncorrected hypoglycaemic or
hyperglycaemic reactions can cause loss of consciousness, coma, or death.
The use of dosages which are inadequate or discontinuation of treatment, especially in insulin-dependent
diabetics, may lead to hyperglycaemia and diabetic ketoacidosis; conditions which are potentially lethal.
Insulin requirements may be reduced in the presence of renal impairment. Insulin requirements may be
reduced in patients with hepatic impairment due to reduced capacity for gluconeogenesis and reduced
insulin breakdown; however, in patients with chronic hepatic impairment, an increase in insulin resistance
may lead to increased insulin requirements.
Insulin requirements may be increased during illness or emotional disturbances.
Adjustment of dosage may also be necessary if patients undertake increased physical activity or change
their usual diet. Exercise taken immediately after a meal may increase the risk of hypoglycaemia. A
consequence of the pharmacodynamics of rapid-acting insulin analogues is that if hypoglycaemia occurs,
it may occur earlier after an injection when compared with soluble human insulin.
Humalog should only be used in children in preference to soluble insulin when a fast action of insulin
might be beneficial. For example, in the timing of the injections in relation to meals.
Combination of Humalog 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 Humalog 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.
Interaction with other medicinal products and other forms of interaction
Insulin requirements may be increased by medicinal products with hyperglycaemic activity, such as oral
contraceptives, corticosteroids, or thyroid replacement therapy, danazol, beta2 stimulants (such as
ritodrine, salbutamol, terbutaline).
Insulin requirements may be reduced in the presence of medicinal products with hypoglycaemic activity,
such as oral hypoglycemics, salicylates (for example, acetylsalicylic acid), sulpha antibiotics, certain
antidepressants (monoamine oxidase inhibitors, selective serotonin reuptake inhibitors), certain
angiotensin converting enzyme inhibitors (captopril, enalapril), angiotensin II receptor blockers, betablockers, octreotide or alcohol.
The physician should be consulted when using other medications in addition to Humalog KwikPen (see
section 4.4).
Fertility, pregnancy and lactation
Data on a large number of exposed pregnancies do not indicate any adverse effect of insulin lispro on
pregnancy or on the health of the foetus/newborn.
It is essential to maintain good control of the insulin-treated (insulin-dependent or gestational diabetes)
patient throughout pregnancy. Insulin requirements usually fall during the first trimester and increase
during the second and third trimesters. Patients with diabetes should be advised to inform their doctor if
they are pregnant or are contemplating pregnancy. Careful monitoring of glucose control, as well as
general health, is essential in pregnant patients with diabetes.
Patients with diabetes who are breast-feeding may require adjustments in insulin dose, diet or both.
Effects on ability to drive and use machines
The patient’s ability to concentrate and react may be impaired as a result of hypoglycaemia. This may
constitute a risk in situations where these abilities are of special importance (e.g. driving a car or operating
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 signs of hypoglycaemia or have
frequent episodes of hypoglycaemia. The advisability of driving should be considered in these
Undesirable effects
Hypoglycaemia is the most frequent undesirable effect of insulin therapy that a patient with diabetes may
suffer. Severe hypoglycaemia may lead to loss of consciousness, and in extreme cases, death. No specific
frequency for hypoglycaemia is presented, since hypoglycaemia is a result of both the insulin dose and
other factors e.g. a patient`s level of diet and exercise.
Local allergy in patients is common (1/100 to <1/10). Redness, swelling, and itching can occur at the site
of insulin injection. This condition usually resolves in a few days to a few weeks. In some instances, this
condition may be related to factors other than insulin, such as irritants in the skin cleansing agent or poor
injection technique. Systemic allergy, which is rare (1/10,000 to <1/1,000) but potentially more serious,
is a generalised allergy to insulin. It may cause a rash over the whole body, shortness of breath, wheezing,
reduction in blood pressure, fast pulse, or sweating. Severe cases of generalised allergy may be lifethreatening.
Lipodystrophy at the injection site is uncommon (1/1,000 to <1/100).
Cases of oedema have been reported with insulin therapy, particularly if previous poor metabolic control
is improved by intensified insulin therapy.
Insulins have no specific overdose definitions because serum glucose concentrations are a result of
complex interactions between insulin levels, glucose availability and other metabolic processes.
Hypoglycaemia may occur as a result of an excess of insulin activity relative to food intake and energy
Hypoglycaemia may be associated with listlessness, confusion, palpitations, headache, sweating and
Mild hypoglycaemic episodes will respond to oral administration of glucose or other sugar or saccharated
Correction of moderately severe hypoglycaemia can be accomplished by intramuscular or subcutaneous
administration of glucagon, followed by oral carbohydrate when the patient recovers sufficiently. Patients
who fail to respond to glucagon must be given glucose solution intravenously.
If the patient is comatose, glucagon should be administered intramuscularly or subcutaneously. However,
glucose solution must be given intravenously if glucagon is not available or if the patient fails to respond
to glucagon. The patient should be given a meal as soon as consciousness is recovered.
Sustained carbohydrate intake and observation may be necessary because hypoglycaemia may recur after
apparent clinical recovery.
Pharmacodynamic properties
Pharmacotherapeutic group : Fast-acting human insulin analogue, ATC code: A10A B04
The primary activity of insulin lispro is the regulation of glucose metabolism.
In addition, insulins have several anabolic and anti-catabolic actions on a variety of different tissues.
Within muscle tissue this includes increasing glycogen, fatty acid, glycerol and protein synthesis and
amino acid uptake, while decreasing glycogenolysis, gluconeogenesis, ketogenesis, lipolysis, protein
catabolism and amino acid output.
Insulin lispro has a rapid onset of action (approximately 15 minutes), thus allowing it to be given closer to
a meal (within zero to 15 minutes of the meal) when compared to regular insulin
(30 to 45 minutes before). Insulin lispro takes effect rapidly and has a shorter duration of activity (2 to
5 hours) when compared to regular insulin.
Clinical trials in patients with type 1 and type 2 diabetes have demonstrated reduced postprandial
hyperglycaemia with insulin lispro compared to soluble human insulin.
As with all insulin preparations, the time course of insulin lispro action may vary in different individuals
or at different times in the same individual and is dependent on dose, site of injection, blood supply,
temperature and physical activity. The typical activity profile following subcutaneous injection is
illustrated below.
Insulin lispro
Humulin R
Time (Hours)
The above representation reflects the relative amount of glucose over time required to maintain the
subject's whole blood glucose concentrations near fasting levels and is an indicator of the effect of these
insulins on glucose metabolism over time.
Clinical trials have been performed in children (61 patients aged 2 to 11) and children and adolescents
(481 patients aged 9 to 19 years), comparing insulin lispro to human soluble insulin. The
pharmacodynamic profile of insulin lispro in children is similar to that seen in adults.
When used in subcutaneous infusion pumps, treatment with insulin lispro has been shown to result in
lower glycosylated haemoglobin levels compared to soluble insulin. In a double-blind, crossover study,
the reduction in glycosylated haemoglobin levels after 12 weeks dosing was 0.37 percentage points with
insulin lispro, compared to 0.03 percentage points for soluble insulin (p = 0.004).
In patients with type 2 diabetes on maximum doses of sulphonyl urea agents, studies have shown that the
addition of insulin lispro significantly reduces HbA1c compared to sulphonyl urea alone. The reduction
of HbA1c would also be expected with other insulin products e.g. soluble or isophane insulins.
Clinical trials in patients with type 1 and type 2 diabetes have demonstrated a reduced number of episodes
of nocturnal hypoglycaemia with insulin lispro compared to soluble human insulin. In some studies,
reduction of nocturnal hypoglycaemia was associated with increased episodes of daytime hypoglycaemia.
The glucodynamic response to insulin lispro is not affected by renal or hepatic function impairment.
Glucodynamic differences between insulin lispro and soluble human insulin, as measured during a
glucose clamp procedure, were maintained over a wide range of renal function.
Insulin lispro has been shown to be equipotent to human insulin on a molar basis but its effect is more
rapid and of a shorter duration.
Pharmacokinetic properties
The pharmacokinetics of insulin lispro reflect a compound that is rapidly absorbed, and achieves peak
blood levels 30 to 70 minutes following subcutaneous injection. When considering the clinical relevance
of these kinetics, it is more appropriate to examine the glucose utilisation curves (as discussed in 5.1).
Insulin lispro maintains more rapid absorption when compared to soluble human insulin in patients with
renal impairment. In patients with type 2 diabetes over a wide range of renal function the
pharmacokinetic differences between insulin lispro and soluble human insulin were generally maintained
and shown to be independent of renal function. Insulin lispro maintains more rapid absorption and
elimination when compared to soluble human insulin in patients with hepatic impairment.
Preclinical safety data
In in vitro tests, including binding to insulin receptor sites and effects on growing cells, insulin lispro
behaved in a manner that closely resembled human insulin. Studies also demonstrate that the dissociation
of binding to the insulin receptor of insulin lispro is equivalent to human insulin. Acute, one month and
twelve month toxicology studies produced no significant toxicity findings.
Insulin lispro did not induce fertility impairment, embryotoxicity or teratogenicity in animal studies.
