1. WHAT METFORMIN IS AND WHAT IT IS USED FOR What Metformin is
Metformin contains metformin, a medicine to treat diabetes. It belongs to a group of medicines called biguanides.
Insulin is a hormone produced by the pancreas that makes your body take in glucose (sugar) from the blood. Your body uses glucose to produce energy or stores it for future use.
If you have diabetes, your pancreas does not make enough insulin or your body is not able to use properly the insulin it produces. This leads to a high level of glucose in your blood. Metformin helps to lower your blood glucose to as normal a level as possible.
If you are an overweight adult, taking Metformin over a long period of time also helps to lower the risk of complications associated with diabetes. Metformin is associated with either a stable body weight or modest weight loss.
What Metformin is used for
Metformin is used to treat patients with type 2 diabetes (also called 'non-insulin dependent diabetes') when diet and exercise alone have not been enough to control your blood glucose levels. It is used particularly in overweight patients.
Adults can take Metformin on its own or together with other medicines to treat diabetes (medicines taken by mouth or insulin).
Children 10 years and over and adolescents can take Metformin on its own or together with insulin.
Do not take Metformin:
• If you are allergic (hypersensitive) to metformin or any of the other ingredients in this liquid (see section 6: Further information).
• if you have kidney or liver problems
• if you have uncontrolled diabetes, with e.g. severe hyperglycaemia (high blood glucose),
nausea, vomiting, dehydration, rapid weight loss or ketoacidosis. Ketoacidosis is a condition in which substances called 'ketone bodies' accumulate in the blood. Symptoms include stomach pain, fast and deep breathing, sleepiness or unusual fruity odour of the breath
• if you lost too much water from your body (dehydration), such as due to long-lasting or
severe diarrhoea, or if you have vomited several times in a row. Dehydration may lead to kidney problems, which can put you at risk for lactic acidosis (see 'Take special care with Metformin below).
• if you have a severe infection, such as an infection affecting your lung or bronchial system or
your kidney. Severe infections may lead to kidney problems, which can put you at risk for lactic acidosis (see 'Take special care with Metformin below).
• if you are treated for heart failure or have recently had a heart attack, have severe problems
with your circulation (such as shock) or have breathing difficulties. This may lead to a lack in oxygen supply to tissue which can put you at risk for lactic acidosis (see 'Take special care with Metformin Alapis below)
• if you drink a lot of alcohol
If any of the above applies to you, talk to your doctor, before you start taking this medicine.
Make sure you ask your doctor for advice, if
• you need to have an examination such as X-ray or scan involving the injection of contrast
medicines that contain iodine into your bloodstream
• you need to have major surgery
You must stop taking Metformin Alapis for a certain period of time before and after the examination or the surgery. Your doctor will decide whether you need any other treatment for this time. It is important that you follow your doctor’s instructions precisely
Take special care with Metformin
Please note the following particular risk of lactic acidosis
Metforminmay cause a very rare, but serious complication called lactic acidosis, particularly if your kidneys are not working properly. The risk of lactic acidosis is also increased with uncontrolled diabetes, prolonged fasting or alcohol intake. Symptoms of lactic acidosis are vomiting, bellyache (abdominal pain) with muscle cramps, a general feeling of not being well with severe tiredness, and difficulty in breathing. If this happens to you, you may need immediate treatment in hospital. Stop taking Metformin immediately and contact your doctor or the nearest hospital straight away.
Metformin on its own does not cause hypoglycaemia (a blood glucose level which is too low). However, if you take Metformin together with other medicines to treat diabetes that can cause hypoglycaemia (such as sulphonylureas, insulin, meglitinides), there is a risk of hypoglycaemia. If you experience symptoms of hypoglycaemia such as weakness, dizziness, increased sweating, fast heart beating, visions disorders or difficulty in concentration, it usually helps to eat or drink something containing sugar.
Taking other medicines
If you need to have an injection of contrast medicines that contain iodine into your bloodstream, for example for examinations such as X-ray or scan, you must stop taking Metformin for a certain period of time before and after the examination (see 'Make sure you ask your doctor for advice' above).
Tell your doctor if you take any of the following medicines and Metformin at the same time. You may need more frequent blood glucose tests or your doctor may adjust the dosage of Metformin:
• diuretics (used to remove water from the body by making more urine).
• sympathomimetics such as salbutamol or terbutaline (used to treat asthma)
• corticosteroids (used to treat a variety of conditions, such as severe inflammation of the skin or in asthma)
other medicines to treat diabetes
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
Taking Metformin with food and drink
Do not drink alcohol when you take this medicine. Alcohol may increase the risk of lactic acidosis especially if you have liver problems or if you are undernourished. This also applies to medicines that contain alcohol
Pregnancy and Breast-feeding
During pregnancy, you need insulin to treat your diabetes. Tell your doctor if you are, you think you might be or are planning to become pregnant, so that he or she may change your treatment.
It is not recommended to take Metformin during breast-feeding. Your doctor will decide whether you should stop breast-feeding while you are treated with Metformin.
Driving and using machines
Metformin on its own does not cause hypoglycaemia (a blood glucose level which is too low). This means that it will not affect your ability to drive or use machines.
However, take special care if you take Metformin together with other medicines to treat diabetes that can cause hypoglycaemia (such as sulphonylureas, insulin, meglitinides). Symptoms of hypoglycaemia include weakness, dizziness, increased sweating, fast heart beat, vision disorders or difficulty in concentration. Do not drive or use machines if you start to feel these symptoms.

4. POSSIBLE SIDE EFFECTS
Like all medicines, Metformin can cause side effects, although not everybody gets them.
The following side effects may occur:
Very common side effects (in more than 1 in 10 users)
• digestive problems, such as feeling sick (nausea), being sick (vomiting), diarrhoea, bellyache (abdominal pain) and loss of appetite. These side effects most often happen at the beginning of the treatment with Metformin. It helps if you spread the doses over the day and if you take the doses with or straight after a meal. If symptoms continue, stop taking Metformin and talk to your doctor.
Common side effects (in less than 1 in 10 users)
• changes in taste.
Very rare side effects (in less than 1 in 10,000 users)
• lactic acidosis. This is a very rare but serious complication particularly if your kidneys are not working properly.
Symptoms of lactic acidosis are vomiting, bellyache (abdominal pain) with muscle cramps, a general feeling of not being well with severe tiredness, and difficulty in breathing. If this happens to you, you may need immediate hospital treatment, as lactic acidosis may lead to coma. Stop taking Metformin immediately and contact your doctor or the nearest hospital straight away.
• skin reactions such as redness of the skin (erythema), itching or an itchy rash (urticaria).
• low vitamin B12 levels in the blood.
• abnormalities in liver function tests or hepatitis (inflammation of the liver; this may cause tiredness, loss of appetite, weight loss, with or without yellowing of the skin or whites of the eyes). If this happens to you, stop taking this medicine and inform you doctor immediately.
