4.2 Posology and method of administration
Posology

The potency of insulin analogues, including insulin detemir, is expressed in units, whereas the potency of human insulin is expressed in international units. 1 unit insulin detemir corresponds to 1 international unit of human insulin.

Levemir can be used alone as the basal insulin or in combination with bolus insulin. It can also be used in combination with oral antidiabetic medicinal products and/or GLP-1 receptor agonists.

When Levemir is used in combination with oral antidiabetic medicinal products or when added to GLP-1 receptor agonists it is recommended to use Levemir once daily, initially at a dose of 0.1–0.2 units/kg or of 10 units in adult patients. The dose of Levemir should be titrated based on the individual patient's needs.

When a GLP-1 receptor agonist is added to Levemir, it is recommended to reduce the dose of Levemir by 20% to minimise the risk of hypoglycaemia. Subsequently, dosage should be adjusted individually.

For individual dose adjustments, the following two titration guidelines are recommended for adults:

Adult type 2 diabetes titration guideline:

Average pre-breakfast SMPG*	Levemir dose adjustment
>10.0 mmol/l (180 mg/dl)	+8 units
9.1–10.0 mmol/l (163–180 mg/dl)	+6 units
8.1–9.0 mmol/l (145–162 mg/dl)	+4 units
7.1–8.0 mmol/l (127–144 mg/dl)	+2 units
6.1–7.0 mmol/l (109–126 mg/dl)	+2 units
4.1–6.0 mmol/l (73–108 mg/dl)	No change in dose (target)
If one SMPG measurement
3.1–4.0 mmol/l (56–72 mg/dl)	-2 units
<3.1 mmol/l (<56 mg/dl)	-4 units

*Self-Monitored Plasma Glucose

Adult type 2 diabetes simple self-titration guideline:

Average pre-breakfast SMPG*	Levemir dose adjustment
>6.1 mmol/l (>110 mg/dl)	+3 units
4.4–6.1 mmol/l (80–110 mg/dl)	No change in dose (target)
<4.4 mmol/l (<80 mg/dl)	-3 units

*Self-Monitored Plasma Glucose

When Levemir is used as part of a basal-bolus insulin regimen, Levemir should be administered once or twice daily depending on patients' needs. The dose of Levemir should be adjusted individually.

Adjustment of dose may be necessary if patients undertake increased physical activity, change their usual diet or during concomitant illness.

When adjusting dose in order to improve glucose control, patients should be advised to be aware of signs of hypoglycaemia.

Special populations

Elderly (≥65 years old)

Levemir can be used in elderly patients. In elderly patients, glucose monitoring should be intensified and the Levemir dose adjusted on an individual basis.

Renal and hepatic impairment

Renal or hepatic impairment may reduce the patient's insulin requirements.

In patients with renal or hepatic impairment, glucose monitoring should be intensified and the Levemir dose adjusted on an individual basis.

Paediatric population

Levemir can be used in adolescents and children from the age of 1 year (see section 5.1). When changing basal insulin to Levemir, dose reduction of basal and bolus insulin needs to be considered on an individual basis, in order to minimise the risk of hypoglycaemia (see section 4.4).

In children and adolescents, glucose monitoring should be intensified and the Levemir dose adjusted on an individual basis.

The safety and efficacy of Levemir in children below the age of 1 year have not been established.

No data are available.

Transfer from other insulin medicinal products

When transferring from other intermediate or long-acting insulin medicinal products, adjustment of the dose and timing of administration may be necessary (see section 4.4).

Close glucose monitoring is recommended during the transfer and in the initial weeks thereafter (see section 4.4).

Concomitant antidiabetic treatment may need to be adjusted (dose and/or timing of oral antidiabetic medicinal products or concurrent short/rapid-acting insulin medicinal products).

Method of administration

Levemir is a long-acting insulin analogue used as a basal insulin. Levemir is for subcutaneous administration only. Levemir must not be administered intravenously, as it may result in severe hypoglycaemia. Intramuscular administration should also be avoided. Levemir is not to be used in insulin infusion pumps.

Levemir is administered subcutaneously by injection in the abdominal wall, the thigh, the upper arm, the deltoid region or the gluteal region. Injection sites should always be rotated within the same region in order to reduce the risk of lipodystrophy. The duration of action will vary according to the dose, injection site, blood flow, temperature and level of physical activity. The injection can be given at any time during the day, but at the same time each day. For patients who require twice daily dosing to optimise blood glucose control, the evening dose can be administered in the evening or at bedtime.

For detailed user instructions, please refer to the package leaflet.

4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients (see section 6.1).

4.4 Special warnings and precautions for use
Before travelling between different time zones, the patient should seek the doctor's advice since this may mean that the patient has to take the insulin and meals at different times.

Hyperglycaemia

Inadequate dosing or discontinuation of treatment, especially in type 1 diabetes, may lead to hyperglycaemia and diabetic ketoacidosis. Usually the first symptoms of hyperglycaemia develop gradually over a period of hours or days. They include thirst, increased frequency of urination, nausea, vomiting, drowsiness, flushed dry skin, dry mouth, loss of appetite as well as acetone odour of breath. In type 1 diabetes, untreated hyperglycaemic events eventually lead to diabetic ketoacidosis, which is potentially lethal.

Hypoglycaemia

Omission of a meal or unplanned, strenuous physical exercise may lead to hypoglycaemia.

In children, care should be taken to match insulin doses (especially in basal-bolus regimens) with food intake and physical activities in order to minimise the risk of hypoglycaemia.

Hypoglycaemia may occur if the insulin dose is too high in relation to the insulin requirement. In case of hypoglycaemia or if hypoglycaemia is suspected, Levemir must not be injected. After stabilisation of the patient's blood glucose, adjustment of the dose should be considered (see sections 4.8 and 4.9).

Patients whose blood glucose control is greatly improved, e.g. by intensified insulin therapy, may experience a change in their usual warning symptoms of hypoglycaemia, and should be advised accordingly. Usual warning symptoms may disappear in patients with longstanding diabetes.

Concomitant illness, especially infections and feverish conditions, usually increases the patient's insulin requirements. Concomitant diseases in the kidney, liver or affecting the adrenal, pituitary or thyroid gland can require changes in insulin dose.

When patients are transferred between different types of insulin medicinal products, the early warning symptoms of hypoglycaemia may change or become less pronounced than those experienced with their previous insulin.

Transfer from other insulin medicinal products

Transferring a patient to another type or brand of insulin should be done under strict medical supervision. Changes in strength, brand (manufacturer), type, origin (animal insulin, human insulin or insulin analogue) and/or method of manufacture (recombinant DNA versus animal source insulin) may result in the need for a change in dose. Patients transferred to Levemir from another type of insulin may require a change in dose from that used with their usual insulin medicinal products. If an adjustment is needed, it may occur with the first dose or during the first few weeks or months.

Injection site reactions

As with any insulin therapy, injection site reactions may occur and include pain, redness, hives, inflammation, bruising, swelling and itching. Continuous rotation of the injection site within a given area may help to reduce or prevent these reactions. Reactions usually resolve in a few days to a few weeks. On rare occasions, injection site reactions may require discontinuation of Levemir.

Hypoalbuminaemia

There are limited data in patients with severe hypoalbuminaemia. Careful monitoring is recommended in these patients.

Combination of Levemir 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 Levemir 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.

Avoidance of accidental mix-ups/medication errors

Patients must be instructed to always check the insulin label before each injection to avoid accidental mix-ups between Levemir and other insulin products.

4.5 Interaction with other medicinal products and other forms of interaction
A number of medicinal products are known to interact with the glucose metabolism.

The following substances may reduce the patient's insulin requirements:

Oral antidiabetic medicinal products, GLP-1 receptor agonists, monoamine oxidase inhibitors (MAOI), beta-blockers, angiotensin converting enzyme (ACE) inhibitors, salicylates, anabolic steroids and sulphonamides.

The following substances may increase the patient's insulin requirements:

Oral contraceptives, thiazides, glucocorticoids, thyroid hormones, sympathomimetics, growth hormone and danazol.

Beta-blockers may mask the symptoms of hypoglycaemia.

Octreotide/lanreotide may either increase or decrease the insulin requirement.

Alcohol may intensify or reduce the hypoglycaemic effect of insulin.

4.6 Fertility, pregnancy and lactation
Pregnancy

Treatment with Levemir can be considered during pregnancy, but any potential benefit must be weighed against a possibly increased risk of an adverse pregnancy outcome.

In general, intensified blood glucose control and monitoring of pregnant women with diabetes are recommended throughout pregnancy and when contemplating pregnancy. Insulin requirements usually fall in the first trimester and increase subsequently during the second and third trimester. After delivery, insulin requirements normally return rapidly to pre-pregnancy values.

In an open-label randomised controlled clinical trial pregnant women with type 1 diabetes (n=310) were treated in a basal-bolus treatment regimen with Levemir (n=152) or NPH insulin (n=158) as basal insulin, both in combination with NovoRapid. Primary objective of this study was to assess the effect of Levemir on blood glucose regulation in pregnant women with diabetes (see section 5.1).

The overall rates of maternal adverse events were similar for Levemir and NPH insulin treatment groups; however, a numerically higher frequency of serious adverse events in the mothers (61 (40%) vs. 49 (31%)) and in the newborn children (36 (24%) vs. 32 (20%)) was seen for Levemir compared to NPH insulin. The number of live born children of women becoming pregnant after randomisation were 50 (83%) for Levemir and 55 (89%) for NPH. The frequency of congenital malformations was 4 (5%) for Levemir and 11 (7%) for NPH with 3 (4%) major malformations for Levemir and 3 (2%) for NPH.

Post-marketing data from an additional 250 outcomes from pregnant women exposed to Levemir indicate no adverse effects of insulin detemir on pregnancy and no malformative or foetal/neonatal toxicity of insulin detemir.

Animal data do not indicate reproductive toxicity (see section 5.3).

Breast-feeding

It is unknown whether insulin detemir is excreted in human milk. No metabolic effects of ingested insulin detemir on the breast-fed newborn/infant are anticipated since insulin detemir, as a peptide, is digested into amino acids in the human gastrointestinal tract.

Breast-feeding women may require adjustments in insulin dose and diet.

Fertility

Animal studies do not indicate harmful effects with respect to fertility.

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. This may constitute a risk in situations where these abilities are of special importance (e.g. driving a car or operating machinery).

Patients should be advised to take precautions to avoid hypoglycaemia while 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 circumstances.

4.8 Undesirable effects
Summary of the safety profile

Adverse reactions observed in patients using Levemir are mainly due to the pharmacologic effect of insulin. The overall percentage of treated patients expected to experience adverse reactions is estimated to be 12%.

The most frequently reported adverse reaction during treatment is hypoglycaemia, please see section 4.8, Description of selected adverse reactions.

From clinical investigations, it is known that major hypoglycaemia, defined as requirement for third party intervention, occurs in approximately 6% of the patients treated with Levemir.

Injection site reactions are seen more frequently during treatment with Levemir than with human insulin products. These reactions include pain, redness, hives, inflammation, bruising, swelling and itching at the injection site. Most of the injection site reactions are minor and of a transitory nature, i.e. they normally disappear during continued treatment in a few days to a few weeks.

At the beginning of the insulin treatment, refraction anomalies and oedema may occur; these reactions are usually of transitory nature. Fast improvement in blood glucose control may be associated with acute painful neuropathy, which is usually reversible. Intensification of insulin therapy with abrupt improvement in glycaemic control may be associated with temporary worsening of diabetic retinopathy, while long-term improved glycaemic control decreases the risk of progression of diabetic retinopathy.

Description of selected adverse reactions

Allergic reactions, potentially allergic reactions, urticaria, rash, eruptions

Allergic reactions, potentially allergic reactions, urticaria, rash and eruptions are uncommon when Levemir is used in basal-bolus regimen. However, when used in combination with oral antidiabetic medicinal products, three clinical studies have shown a frequency of common (2.2% of allergic reactions and potentially allergic reactions have been observed).

Anaphylactic reactions

The occurrence of generalised hypersensitivity reactions (including generalised skin rash, itching, sweating, gastrointestinal upset, angioneurotic oedema, difficulties in breathing, palpitation and reduction in blood pressure) is very rare but can potentially be life threatening.

Hypoglycaemia

The most frequently reported adverse reaction is hypoglycaemia. It may occur if the insulin dose is too high in relation to the insulin requirement. Severe hypoglycaemia may lead to unconsciousness and/or convulsions and may result in temporary or permanent impairment of brain function or even death. The symptoms of hypoglycaemia usually occur suddenly. They may include cold sweats, cool pale skin, fatigue, nervousness or tremor, anxiousness, unusual tiredness or weakness, confusion, difficulty in concentrating, drowsiness, excessive hunger, vision changes, headache, nausea and palpitation.

Lipodystrophy

Lipodystrophy (including lipohypertrophy, lipoatrophy) may occur at the injection site. Continuous rotation of the injection site within the particular injection area reduces the risk of developing these reactions.

Paediatric population

Based on post-marketing sources and clinical trials, the frequency, type and severity of adverse reactions observed in the paediatric population do not indicate any differences to the broader experience in the general diabetes population.

Other special populations

Based on post-marketing sources and clinical trials, the frequency, type and severity of adverse reactions observed in elderly patients and in patients with renal or hepatic impairment do not indicate any differences to the broader experience in the general population.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via

4.9 Overdose
A specific overdose for insulin cannot be defined, however, hypoglycaemia may develop over sequential stages if too high doses relative to the patient's requirement are administered:

• Mild hypoglycaemic episodes can be treated by oral administration of glucose or sugary products. It is therefore recommended that the diabetic patient always carries sugar-containing products.

• Severe hypoglycaemic episodes, where the patient has become unconscious, can be treated with glucagon (0.5 to 1 mg) given intramuscularly or subcutaneously by a trained person, or with glucose given intravenously by a healthcare professional. Glucose must be given intravenously, if the patient does not respond to glucagon within 10 to 15 minutes. Upon regaining consciousness, administration of oral carbohydrates is recommended for the patient in order to prevent a relapse.

5. Pharmacological properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Drugs used in diabetes. Insulins and analogues for injection, long-acting: ATC code: A10AE05.

Mechanism of action and pharmacodynamic effects

Levemir is a soluble, long-acting insulin analogue with a prolonged duration of effect used as a basal insulin.

The blood glucose lowering effect of Levemir is due to the facilitated uptake of glucose following binding of insulin to receptors on muscle and fat cells and to the simultaneous inhibition of glucose output from the liver.

The time action profile of Levemir is statistically significantly less variable and therefore more predictable than for NPH (Neutral Protamine Hagedorn) insulin as seen from the within-subject Coefficients of Variation (CV) for the total and maximum pharmacodynamic effect in Table 1.

Table 1. Within-subject variability of the time action profile of Levemir and NPH insulin

Pharmacodynamic Endpoint	Levemir CV (%)	NPH insulin CV (%)
AUCGIR,0-24h*	27	68
GIRmax**	23	46

*Area under the curve ** Glucose Infusion Rate p-value <0.001 for all comparisons with Levemir

The prolonged action of Levemir is mediated by the strong self-association of insulin detemir molecules at the injection site and albumin binding via the fatty acid side-chain. Insulin detemir is distributed more slowly to peripheral target tissues compared to NPH insulin. These combined mechanisms of protraction provide a more reproducible absorption and action profile of insulin detemir compared to NPH insulin.

Figure 1. Activity profiles of Levemir in patients with type 1 diabetes

The duration of action is up to 24 hours depending on dose providing an opportunity for once or twice daily administration. If administered twice daily, steady state will occur after 2–3 dose administrations. For doses in the interval of 0.2–0.4 units/kg (U/kg), Levemir exerts more than 50% of its maximum effect from 3–4 hours and up to approximately 14 hours after dose administration.

Dose proportionality in pharmacodynamic response (maximum effect, duration of action, total effect) is observed after subcutaneous administration.

Lower day-to-day variability in FPG was demonstrated during treatment with Levemir compared to NPH in long-term clinical trials.

Studies in patients with type 2 diabetes treated with basal insulin in combination with oral antidiabetic medicinal products demonstrated that glycaemic control (HbA1c) with Levemir is comparable to NPH insulin and insulin glargine and associated with less weight gain, see Table 2 below. In the study versus insulin glargine, Levemir was allowed to be administered once or twice daily whereas insulin glargine was to be administered once a day, 55% of the Levemir treated patients completed the 52 weeks of treatment on the twice daily regimen.

Table 2. Change in body weight after insulin treatment

Study duration	Levemir once daily	Levemir twice daily	NPH insulin	Insulin glargine
20 weeks	+0.7 kg		+1.6 kg
26 weeks		+1.2 kg	+2.8 kg
52 weeks	+2.3 kg	+3.7 kg		+4.0 kg

In trials investigating the use of oral antidiabetic medicinal products, combination therapy with Levemir resulted in a 61-65% lower risk of minor nocturnal hypoglycaemia compared to NPH insulin.

An open-label randomised clinical trial in patients with type 2 diabetes not reaching target with oral antidiabetic medicinal products was conducted. The trial started with a 12-week run-in period with liraglutide+metformin, where 61% reached an HbA1c <7%. The 39% of patients not achieving target were randomised to have Levemir once-daily added or continue on liraglutide+metformin for 52 weeks. Addition of Levemir provided a further reduction of HbA1c from 7.6% to 7.1% after 52 weeks. There were no major hypoglycaemic episodes. A major hypoglycaemic episode is defined as an episode where the subject was not able to treat him/herself and if glucagon or i.v. glucose was needed. See table 3.
