What it is and what it is used for

for

Glimepiride is one of a group of medicines called oral hypoglycaemics, which are used for treatment of diabetes (a disease where the body does not produce enough insulin to control the level of blood sugar). Oral hypoglycaemics help control blood sugar level. The active ingredient in your Glimepiride tablets is Glimepiride. What Glimepiride is used for: Glimepiride is used in the treatment of non-insulin dependent (Type II) diabetes mellitus. You get diabetes if your pancreas does not make enough insulin to control the level of glucose in your blood. Type II diabetes can sometimes be controlled by good diet, physical exercise and weight reduction alone, but where this is not possible, Glimepiride is used in addition.

What you need to know before you take it

e Glimepiride.

Do not take Glimepiride: • • •

if you are allergic to glimepiride or other sulfonylureas (medicines used to lower your blood sugar such as glibenclamide) or sulfonamides (medicines for bacterial infections such as sulfamethoxazole) or any of the other ingredients of this medicine (listed in section 6) if you have insulin dependent diabetes (Type I diabetes mellitus) if you have diabetic ketoacidosis (a complication of diabetes when your acid level is raised in your body and you may have some of the following signs: fatigue, feeling sick (nausea), frequent urination and muscular stiffness)

• • •

if you are in a diabetic coma if you have severe kidney disease if you have a severe liver disease

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Glimepiride. Warnings and precautions: Talk to your doctor or pharmacist before taking Glimepiride if: • •

You are recovering from an injury, operation, infections with fever, or from other forms of stress, inform your doctor as temporary change of treatment may be necessary. You have a severe liver or kidney disorder .

If you are not sure if any of these apply to you, talk to your doctor or pharmacist before taking Glimepiride. Lowering of the haemoglobin level and breakdown of red blood cells (haemolytic anemia) can occur in patients missing the enzyme glucose-6-phosphate dehydrogenase. The information available on the use of Glimepiride in people under 18 years of age is limited. Therefore, its use in these patients is not recommended.

Important information about hypoglycaemia (low blood sugar) When you take Glimepiride, you may get hypoglycaemia (low blood sugar). Please see below for additional information about hypoglycaemia, its signs and treatment. Following factors could increase the risk of you getting hypoglycaemia: • • • • • • • • •

Undernourishment, irregular meal time, missed or delayed meal or period of fasting Changes to your diet Taking more Glimepiride than needed Having kidneys that do not work properly Having severe liver disease If you suffer from particular hormone-induced disorders (disorders of the thyroid glands, of the pituitary gland or adrenal cortex) Drinking alcohol (especially when you skip a meal) Taking certain other medicines (see below "Other medicines and Glimepiride") If you increase the amount of exercise you do and you don't eat enough food or eat food containing less carbohydrate than usual.

Signs of hypoglycaemia include: •

•

Hunger pangs, headache, nausea, vomiting, sluggishness, sleepiness, problems sleeping, restlessness, aggression, problems with concentration, reduced alertness and reaction time, depression, confusion, problems with your speech and sight, slurred speech, shakiness, partial paralysis, sensory disturbances, dizziness, helplessness The following signs may also occur: sweating, clammy skin, anxiety, fast or increased heart beat, high blood pressure, awareness of your heart beat (palpitations), sudden strong pain in the breast that may radiate into neighbouring areas (angina pectoris and cardiac arrhythmias)

If blood sugar levels continue to drop you may suffer from considerable confusion (delirium), develop fits (convulsions), lose self control, breathing may be shallow and your heart beat slowed down, you may fall into unconsciousness. The clinical picture of a severe reduced blood sugar level may resemble that of a stroke. Treating hypoglycaemia: In most cases the signs of reduced blood sugar vanish very quickly when you consume some form of sugar, e.g. sugar cubes, sweet juice, sweetened tea. You should therefore always take some form of sugar with you (e.g. sugar cubes). Remember that artificial sweeteners are not effective. Please contact your doctor or go to the hospital if taking sugar does not help or if the symptoms recur. Laboratory tests The level of sugar in your blood or urine should be checked regularly. Your doctor may also take blood tests to monitor your blood cell levels and liver function. Children and adolescents Glimepiride is not recommended for use in children under 18 years of age. Other medicines and Glimepiride Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Your doctor may wish to change your dose of Glimepiride if you are taking other medicines, which may weaken or strengthen the effect of Glimepiride on the level of sugar in your blood. The following medicines can increase the blood sugar lowering effect of Glimepiride. This can lead to a risk of hypoglycaemia (low blood sugar): • Other medicines to treat diabetes mellitus (such as insulin or metformin) • Medicines to treat pain and inflammation (phenylbutazone, azopropazone, oxyphenbutazone, aspirin-like medicines) • Medicines to treat urinary infections (such as some long acting sulfonamides) • Medicines to treat bacterial and fungal infections (tetracyclines, chloramphenicol, fluconazole, miconazole, quinolones, clarithromycin) • Medicines to inhibit blood clotting (coumarin derivatives such as warfarin) • Medicines supporting muscle build up (anabolics) • Medicines used for male sex hormone replacement therapy • Medicines to treat depression (fluoxetine, MAO inhibitors) • Medicines lowering high cholesterol level (fibrates) • Medicines lowering high blood pressure (ACE inhibitors) • Medicines called anti-arrhythmic agents used to control abnormal heart beat (disopyramide) • Medicines to treat gout (allopurinol, probenecid, sulfinpyrazone) • Medicines to treat cancer (cyclophosphamide, ifosfamide, trofosfamide) • Medicines used to reduce weight (fenfluramine) • Medicines to increase circulation when given in a high dose intravenous infusion (pentoxifylline) • Medicines to treat nasal allergies such as hay fever (tritoqualine) • Medicines called sympatholytics to treat high blood pressure, heart failure, or prostate symptoms

The following medicines may decrease the blood sugar lowering effect of Glimepiride. This can lead to a risk of hyperglycaemia (high blood sugar level): • Medicines containing female sex hormones (oestrogens, progestogens) • Medicines to treat high blood pressure called thiazide diuretics (water tablets) • Medicines used to stimulate the thyroid gland (such as levothyroxine) • Medicines to treat allergies and inflammation (glucocorticoids) • Medicines to treat severe mental disorders (chlorpromazine and other phenothiazine derivatives) • Medicines used to raise heart beat, to treat asthma or nasal congestion, coughs and colds, used to reduce weight, or used in life-threatening emergencies (adrenaline and sympathomimetics) • Medicines to treat high cholesterol level (nicotinic acid) • Medicines to treat constipation when they are used long term (laxatives) • Medicines to treat fits (phenytoin) • Medicines to treat nervousness and sleep problems (barbiturates) • Medicines to treat increased pressure in the eye (azetazolamide) • Medicines to treat high blood pressure or low blood sugar (diazoxide) • Medicines to treat infections, tuberculosis (rifampicine) • Medicines to treat severe low blood sugar levels (glucagon) The following medicines can increase or decrease the blood sugar lowering effect of Glimepiride: • Medicines to treat stomach ulcers (called H2 antagonists) • Medicines to treat high blood pressure or heart failure such as beta-blockers, clonidine, guanethidine and reserpine. These can also hide the signs of hypoglycaemia, so special care is needed when taking these medicines Glimepiride may either increase or weaken the effects of the following medicines: • Medicines inhibiting blood clotting (coumarin derivatives such as warfarin). • Colesevelam, a medicine used to reduce cholesterol, has an effect on the absorption of Glimepiride. To avoid this effect, you should be advised to take Glimepiride at least 4 hours before colesevelam Glimepiride with food, drink and alcohol Alcohol intake may increase or decrease the blood sugar lowering action of Glimepiride in an unpredictable way. Pregnancy and breast-feeding Pregnancy Glimepiride should not be taken during pregnancy. Tell your doctor if you are, you think you might be or are planning to become pregnant. Breast-feeding Glimepiride may pass into breast milk. Glimepiride should not be taken during breast feeding. If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Driving and using machines Your ability to concentrate or react may be impaired if your blood sugar is lowered (hypoglycaemia), or raised (hyperglycaemia) or if you develop visual problems as a result of such conditions. Bear in mind that

you could endanger yourself or others (e.g. when driving a car or using machines). Please ask your doctor whether you can drive a car if you: • have frequent episodes of hypoglycaemia, • have fewer or no warning signals of hypoglycaemia. Glimepiride tablets contains lactose If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

How to take it

Glimepiride tablets.

Always take Glimepiride tablets exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. Taking this medicine •

Take this medicine by mouth, just before or with the first main meal of the day (usually breakfast). If you do not have breakfast you should take the medicine on schedule as prescribed by your doctor. It is important not to leave out any meal when you are on Glimepiride • The tablet can be divided into equal doses. Swallow the tablets with at least half glass of water. Do not crush or chew the tablets. How much to take The dose of glimepiride depends on your needs, condition and results of blood and urine sugar tests and is determined by your doctor. Do not take more tablets than your doctor has prescribed. • The usual starting dose is one glimepiride 1 mg tablet once a day • If necessary, your doctor may increase the dose after each 1 – 2 weeks of treatment • The maximum recommended dose is 6mg per day • A combination therapy of glimepiride plus metformin or of glimepiride plus insulin may be initiated. In such a case your doctor will determine the proper doses of glimepiride, metformin or insulin individually for you • If your weight changes or if you change your lifestyle, or you are in a stress situation this may require changed glimepiride doses, therefore inform your doctor. • If you feel the effect of your medicine is too weak or too strong do not change the dose yourself, but ask your doctor If you take more Glimepiride than you should If you happen to have taken too much Glimepiride or an additional dose there is a danger of hypoglycaemia ( for signs of hypoglycaemia see section 2) and therefore you should instantly consume enough sugar (e.g. a small bar of sugar cubes, sweet juice, sweetened tea) and inform a doctor immediately. When treating hypoglycaemia due to accidental intake in children, the quantity of sugar given must be carefully controlled to avoid the possibility of producing dangerous hyperglycaemia. Persons in a state of unconsciousness must not be given food or drink. Since the state of hypoglycaemia may last for some time it is very important that the patient is carefully monitored until there is no more danger. Admission into hospital may be necessary, also as a measure of precaution. Show the doctor the package or remaining tablets, so the doctor knows what has been taken. Severe cases of hypoglycaemia accompanied by loss of consciousness and coma (severe neurological failure) are cases of medical emergency requiring immediate medical treatment and admission into

hospital. It may be helpful to tell your family and friends to call a doctor immediately if this happens to you. If you forget to take Glimepiride If you forget to take a tablet, do not take a double dose to make up for forgotten doses. If you stop taking Glimepiride If you interrupt or stop the treatment you should be aware that the desired blood sugar lowering effect is not achieved or that the disease will get worse again. Keep taking Glimepiride until your doctor tells you to stop. If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Possible side effects

Like all medicines, Glimepiride can cause side effects, although not everybody gets them. Tell your doctor immediately if you experience any of the following symptoms: • Allergic reactions (including inflammation of blood vessels, often with skin rash) which may develop into serious reactions with difficulty in breathing, fall in blood pressure and sometimes progressing to shock • Abnormal liver function including yellowing of the skin and eyes (jaundice), problems with the bile flow(cholestasis), inflammation of the liver (hepatitis) or liver failure • Allergy (hypersensitivity) of the skin such as itching, rash, hives and increased sensitivity to sun. Some mild allergic reactions may develop into serious reactions • Severe hypoglycaemia including loss of consciousness, seizures or coma Some patients experienced the following side effects whilst taking Glimepiride: Rare side effects (may affect up to 1 in 1,000 people) • Lower blood sugar than normal (hypoglycaemia) (see section 2) • Decrease in the number of blood cells

  • Blood platelets (which increases risk of bleeding or bruising)
  • White blood cells (which makes infections more likely)
  • Red blood cells (which can make the skin pale and cause weakness or breathlessness) These problems generally get better after you stop taking Glimepiride
  • Changes in your sense of taste.
  • Loss of hair.
  • Weight gain. Very rare side effects (may affect up to 1 in 10,000 people) • Allergic reactions (including inflammation of blood vessels, often with skin rash) which may develop into serious reactions with difficulty in breathing, fall in blood pressure and sometimes progressing to shock. If you experience any of these symptoms, tell your doctor immediately • Abnormal liver function including yellowing of the skin and eyes (jaundice), impairment of the bile flow(cholestasis), inflammation of the liver (hepatitis) or liver failure. If you experience any of these symptoms, tell your doctor immediately • Feeling or being sick, diarrhoea, feeling full or bloated, and abdominal pain

•

Decrease in the amount of sodium level in your blood (shown by blood tests)

•

Not known side effects (frequency cannot be estimated from the available data)Allergy (hypersensitivity) of the skin may occur such as itching, rash, hives and increased sensitivity to sun. Some mild allergic reactions may develop into serious reactions with swallowing or breathing problems, swelling of your lips, throat or tongue. Therefore in the event of one of these side effects, tell your doctor immediately Allergic reactions with sulfonylureas, sulfonamides, or related medicines may occur Problems with your sight may occur when beginning treatment with Glimepiride. This is due to changes in blood sugar levels and should soon improve Increased liver enzymes Severe unusual bleeding or bruising under the skin

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Glimepiride is indicated for the treatment of type 2 diabetes mellitus, when diet, physical exercise and weight reduction alone are not adequate.

4.2. Posology and method of administration

Posology

For oral administration

The basis for successful treatment of diabetes is a good diet, regular physical activity, as well as routine checks of blood and urine. Tablets or insulin cannot compensate if the patient does not keep to the recommended diet.

Dose is determined by the results of blood and urinary glucose determinations.

The starting dose is 1 mg glimepiride per day. If good control is achieved this dose should be used for maintenance therapy.

For the different dose regimens appropriate strengths are available.

If control is unsatisfactory the dosage should be increased, based on the glycaemic control, in a stepwise manner with an interval of about 1 to 2 weeks between each step, to 2, 3 or 4 mg glimepiride per day.

A dose of more than 4 mg glimepiride per day gives better results only in exceptional cases. The maximum recommended dose is 6 mg glimepiride per day.

In patients not adequately controlled with the maximum daily dose of metformin, concomitant glimepiride therapy can be initiated if necessary.

While maintaining the metformin dose, the glimepiride therapy is started at low dose, and is then titrated up depending on the desired level of metabolic control up to the maximum daily dose. The combination therapy should be initiated under close medical supervision.

In patients not adequately controlled with the maximum daily dose of Glimepiride, concomitant insulin therapy can be initiated if necessary. While maintaining the glimepiride dose, insulin treatment is started at low dose and titrated up depending on the desired level of metabolic control. The combination therapy should be initiated under close medical supervision.

Normally a single daily dose of glimepiride is sufficient. It is recommended that this dose be taken shortly before or during a substantial breakfast or - if none is taken - shortly before or during the first main meal.

If a dose is forgotten, this should not be corrected by increasing the next dose.

If a patient has a hypoglycaemic reaction on 1 mg glimepiride daily, this indicates that they can be controlled by diet alone.

In the course of treatment, as an improvement in control of diabetes is associated with higher insulin sensitivity, glimepiride requirements may fall. To avoid hypoglycaemia timely dose reduction or cessation of therapy must therefore be considered. Change in dosage may also be necessary, if there are changes in weight or life style of the patient, or other factors that increase the risk of hypo-or hyperglycaemia.

Switch over from other oral hypoglycaemic agents to Glimepiride

A switch over from other oral hypoglycaemic agents to glimepiride can generally be done. For the switch over to glimepiride the strength and the half life of the previous medication has to be taken into account. In some cases, especially in antidiabetic medicines with a long half life (e.g. chlorpropamide), a wash out period of a few days is advisable in order to minimise the risk of hypoglycaemic reactions due to the additive effect.

The recommended starting dose is 1 mg glimepiride per day. Based on the response the glimepiride dosage may be increased stepwise, as indicated earlier.

Switch over from Insulin to Glimepiride

In exceptional cases, where type 2 diabetic patients are regulated on insulin, a changeover to glimepiride may be indicated. The changeover should be undertaken under close medical supervision.

Special Populations

Patients with renal or hepatic impairment:

See section 4.3.

Paediatric population:

There are no data available on the use of glimepiride in patients under 8 years of age. For children aged 8 to 17 years, there are limited data on glimepiride as monotherapy (see sections 5.1 and 5.2).

The available data on safety and efficacy are insufficient in the paediatric population and therefore such use is not recommended.

Method of administration

Tablets should be swallowed whole with some liquid.

4.3. Contraindications

Glimepiride is contraindicated in patients with the following conditions:

- hypersensitivity to glimepiride, other sulfonylureas or sulfonamides or to any of the excipients listed in section 6.1

- diabetes mellitus type 1,

- diabetic coma,

- ketoacidosis,

- severe renal or hepatic function disorders. In case of severe renal or hepatic function disorders, a changeover to insulin is required.

4.4. Special warnings and precautions for use

Glimepiride must be taken shortly before or during a meal.

When meals are taken at irregular hours or skipped altogether, treatment with Glimepiride may lead to hypoglycaemia. Possible symptoms of hypoglycaemia include: headache, ravenous hunger, nausea, vomiting, lassitude, sleepiness, disordered sleep, restlessness, aggressiveness, impaired concentration, alertness and reaction time, depression, confusion, speech and visual disorders, aphasia, tremor, paresis, sensory disturbances, dizziness, helplessness, loss of self-control, delirium, cerebral convulsions, somnolence and loss of consciousness up to and including coma, shallow respiration and bradycardia. In addition, signs of adrenergic counter-regulation may be present such as sweating, clammy skin, anxiety, tachycardia, hypertension, palpitations, angina pectoris and cardiac arrhythmias.

The clinical picture of a severe hypoglycaemic attack may resemble that of a stroke.

Symptoms can almost always be promptly controlled by immediate intake carbohydrates (sugar). Artificial sweeteners have no effect.

It is known from other sulphonylureas that, despite initially successful countermeasures, hypoglycaemia may recur.

Severe hypoglycaemia or prolonged hypoglycaemia, only temporarily controlled by the usual amounts of sugar, require immediate medical treatment and occasionally hospitalisation.

Factors favouring hypoglycaemia include:

- unwillingness or (more commonly in elderly patients) incapacity of the patient to cooperate,

- undernutrition, irregular mealtimes or missed meals or periods of fasting,

- alterations in diet,

- imbalance between physical exertion and carbohydrate intake,

- consumption of alcohol, especially in combination with skipped meals,

- impaired renal function,

- serious liver dysfunction,

- overdosage with Glimepiride,

- certain uncompensated disorders of the endocrine system affecting carbohydrate metabolism orcounter-regulation of hypoglycaemia (as for example in certain disorders of thyroid function and in anterior pituitary or adrenocortical insufficiency),

- concurrent administration of certain other medicinal products (see Interactions 4.5).

Treatment with Glimepiride requires regular monitoring of glucose levels in blood and urine. In addition determination of the proportion of glycosylated haemoglobin is recommended.

Regular hepatic and haematological monitoring (especially leucocytes and thrombocytes) are required during treatment with Glimepiride.

In stress-situations (e.g. accidents, acute operations, infections with fever, etc.) a temporary switch to insulin may be indicated.

No experience has been gained concerning the use of Glimepiride in patients with severe impairment of liver function or dialysis patients. In patients with severe impairment of renal or liver function change over to insulin is indicated.

Treatment of patients with G6PD-deficiency with sulfonylurea agents can lead to haemolytic anaemia. Since glimepiride belongs to the class of sulfonylurea agents, caution should be used in patients with G6PD-deficiency and a non-sulfonylurea alternative should be considered.

Glimepiride contains lactose monohydrate. Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

4.5. Interaction with other medicinal products and other forms of interaction

If glimepiride is taken simultaneously with certain other medicinal products, both undesired increases and decreases in the hypoglycaemic effect of glimepiride can occur. For this reason, other medicinal products should only be taken with the knowledge (or at the prescription) of the doctor.

Glimepiride is metabolized by cytochrome P450 2C9 (CYP2C9). Its metabolism is known to be influenced by concomitant administration of CYP2C9 inducers (e .g. rifampicin) or inhibitors (e.g. fluconazole).

Results from an in vivo interaction study reported in literature show that glimepiride AUC is increased approximately 2-fold by fluconazole, one of the most potent CYP2C9 inhibitors.

Based on the experience with glimepiride and with other sulphonylureas the following interactions have to be mentioned.

Potentiation of the blood-glucose-lowering effect and, thus, in some instances hypoglycaemia may occur when one of the following medicinal products is taken, for example:

- phenylbutazone, azapropazone and oxyfenbutazone,

- insulin and oral antidiabetic products, such as metformin,

- salicylates and p-amino-salicylic acid,

- anabolic steroids and male sex hormones,

- chloramphenicol, certain long acting sulfonamides, tetracyclines, quinolone antibiotics and clarithromycin,

- coumarin anticoagulants,

- fenfluramine,

- disopyramide,

- fibrates,

- ACE inhibitors,

- fluoxetine, MAO-inhibitors,

- allopurinol, probenecid, sulfinpyrazone,

- sympatholytics,

- cyclophosphamide, trophosphamide and iphosphamides,

- miconazole, fluconazole.

- pentoxifylline (high dose parenteral),

- tritoqualine.

Weakening of the blood-glucose-lowering effect and, thus raised blood glucose levels may occur when one of the following medicinal products is taken, for example:

- oestrogens and progestogens,

- saluretics, thiazide diuretics,

- thyroid stimulating agents, glucocorticoids,

- phenothiazine derivatives, chlorpromazine,

- adrenaline and sympathicomimetics,

- nicotinic acid (high dosages) and nicotinic acid derivatives,

- laxatives (long term use),

- phenytoin, diazoxide,

- glucagon, barbiturates and rifampicin,

- acetazolamide.

H2 antagonists, betablockers, clonidine and reserpine may lead to either potentiation or weakening of the blood glucose lowering effect.

Under the influence of sympatholytic medicinal products such as beta blockers, clonidine, guanethidine and reserpine, the signs of adrenergic counter regulation to hypoglycaemia may be reduced or absent.

Alcohol intake may potentiate or weaken the hypoglycaemic action of glimepiride in an unpredictable fashion.

Glimepiride may either potentiate or weaken the effects of coumarin derivatives.

Colesevelam binds to glimepiride and reduces glimepiride absorption from the gastro-intestinal tract. No interaction was observed when glimepiride was taken at least 4 hours before colesevelam. Therefore, glimepiride should be administered at least 4 hours prior to colesevelam.

4.6. Fertility, pregnancy and lactation

Pregnancy

Risk related to the diabetes

Abnormal blood glucose levels during pregnancy are associated with a higher incidence of congenital abnormalities and perinatal mortality. So the blood glucose level must be closely monitored during pregnancy in order to avoid the teratogenic risk. The use of insulin is required under such circumstances. Patients who consider pregnancy should inform their physician.

Risk related to glimepiride

There are no adequate data from the use of glimepiride in pregnant women. Animal studies have shown reproductive toxicity which likely was related to the pharmacologic action (hypoglycaemia) of glimepiride (see section 5.3).

Consequently, glimepiride should not be used during the whole pregnancy.

In case of treatment by glimepiride, if the patient plans to become pregnant or if a pregnancy is discovered, the treatment should be switched as soon as possible to insulin therapy.

Breast-feeding

The excretion in human milk is unknown. Glimepiride is excreted in rat milk. As other sulfonylureas are excreted in human milk and because there is a risk of hypoglycaemia in nursing infants, breast-feeding is advised against during treatment with glimepiride.

Fertility

No data on fertility is available.

4.7. Effects on ability to drive and use machines

No studies on the effects on the ability to drive and use machines have been performed.

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 machinery).

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 machinery in these circumstances.

4.8. Undesirable effects

The following adverse reactions from clinical investigations were based on experience with Glimepiride and other sulfonylureas, were listed below by system organ class and in order of decreasing incidence (very common: ≥1/l0; common: ≥1/100 to <1/10; uncommon: ≥1/1,000 to <1/100; rare: ≥1/10,000 to <1/1,000; very rare: < 1/10,000), not known (cannot be estimated from the available data).

Blood and lymphatic system disorders

Rare: thrombocytopenia, leukopenia, granulocytopenia, agranulocytosis, erythropenia, haemolytic anaemia and pancytopenia, which are in general reversible upon discontinuation of medication. . Not known: severe thrombocytopenia with platelet count less than 10,000/μl and thrombocytopenic purpura.

Immune system disorders

Very rare: leukocytoclaslic vasculitis, mild hypersensitivity reactions that may develop into serious reactions with dyspnoea, fall in blood pressure and sometimes shock.

Not known: cross-allergenicity with sulfonylureas, sulfonamides or related substances is possible.

Metabolism and nutrition disorders

Rare: hypoglycaemia.

These hypoglycaemic reactions mostly occur immediately, may be severe and are not always easy to correct. The occurrence of such reactions depends, as with other hypoglycaemic therapies, on individual factors such as dietary habits and dosage (see further under section 4.4).

Eye disorders

Not known: visual disturbances, transient, may occur especially on initiation of treatment, due to changes in blood glucose levels.

Gastrointestinal disorders

4.9. Overdose

Symptoms

After ingestion of an overdosage hypoglycaemia may occur, lasting from 12 to 72 hours, and may recur after an initial recovery. Symptoms may not be present for up to 24 hours after ingestion. In general observation in hospital is recommended. Nausea, vomiting and epigastric pain may occur. The hypoglycaemia may in general be accompanied by neurological symptoms like restlessness, tremor, visual disturbances, co-ordination problems, sleepiness, coma and convulsions.

Management

Treatment primarily consists of preventing absorption by inducing vomiting and then drinking water or lemonade with activated charcoal (adsorbent) and sodium-sulphate (laxative). If large quantities have been ingested, gastric lavage is indicated, followed by activated charcoal and sodium-sulphate. In case of (severe) overdosage hospitalisation in an intensive care department is indicated. Start the administration of glucose as soon as possible, if necessary by a bolus intravenous injection of 50 ml of a 50% solution, followed by an infusion of a 10% solution with strict monitoring of blood glucose. Further treatment should be symptomatic.

Paediatric population

In particular when treating hypoglycaemia due to accidental intake of Glimepiride in infants and young children, the dose of glucose given must be carefully controlled to avoid the possibility of producing dangerous hyperglycaemia. Blood glucose should be closely monitored.
