1. What Metformin 750mg Prolonged-Release Tablets are and what they are used for
Metformin 750mg prolonged-release tablets contain the active ingredient metformin hydrochloride and belong to a group of medicines called biguanides, used in the treatment of Type 2 (non-insulin dependent) diabetes mellitus.
Metformin 750mg Prolonged-Release Tablets are used together with diet and exercise to lower the risk of developing Type 2 diabetes in overweight adults, when diet and exercise alone for 3 to 6 months have not been enough to control blood glucose (sugar). You are at high risk of developing Type 2 diabetes if you have additional conditions like high blood pressure, age above 40 years, an abnormal amount of lipids (fat) in the blood or a history of diabetes during pregnancy.
The medicine is particularly effective if you are aged below 45 years, are very overweight, have high blood glucose levels after a meal or developed diabetes during pregnancy.
Metformin is used for the treatment of Type 2 diabetes when diet and exercise changes alone have not been enough to control blood glucose (sugar). Insulin is a hormone that enables body tissues to take glucose from the blood and use it for energy or for storage for future use. People with Type 2 diabetes do not make enough insulin in their pancreas or their body does not respond properly to the insulin it does make. This causes a build-up of glucose in the blood which can cause a number of serious long-term problems, so it is important that you continue to take your medicine, even though you may not have any obvious symptoms. Metformin makes the body more sensitive to insulin and helps return to the normal way your body uses glucose.
Metformin is associated with either a stable body weight or modest weight loss.
Metformin 750mg Prolonged-Release Tablets are specially made to release the drug slowly in your body and therefore are different to many other types of tablet containing metformin.
2. what you need to know before you take metformin 750mg prolonged-release tablets
Do not take Metformin 750mg Prolonged-Release Tablets if you:
- are allergic to metformin or any of the other ingredients of this medicine (listed in section 6). An allergic reaction may cause a rash, itching or shortness of breath.
- have liver problems.
- have severely reduced kidney function.
- have uncontrolled diabetes, with, for example, severe hyperglycaemia (high blood glucose), nausea, vomiting, diarrhoea, rapid weight loss, lactic acidosis (see “Risk of lactic acidosis” below) or ketoacidosis. Ketoacidosis is a condition in which substances called ‘ketone bodies’ accumulate in the blood and which can lead to diabetic pre-coma. Symptoms include stomach pain, fast and deep breathing, sleepiness or your breath developing an unusual fruity smell.
- have lost too much water from your body (dehydration). Dehydration may lead to kidney problems, which can put you at risk for lactic acidosis (see section “Warnings and precautions”).
- 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 section “Warnings and precautions”).
- have been treated for acute heart problems or have recently had a heart attack or have severe circulatory problems or breathing difficulties. This may lead to a lack in oxygen supply to tissue which can put you at risk for lactic acidosis (see section “Warnings and precautions”).
- are a heavy drinker of alcohol.
- are under the age of 18 years.
Warning and precautions
Talk to your doctor or pharmacist before taking Metformin 750mg Prolonged-Release Tablets.
Risk of lactic acidosis
Metformin may cause a very rare, but very serious side effect called lactic acidosis, particularly if your kidneys are not working properly. The risk of developing lactic acidosis is also increased with uncontrolled diabetes, serious infections, prolonged fasting or alcohol intake, dehydration (see further information below), liver problems and any medical conditions in which a part of the body has a reduced supply of oxygen (such as acute severe heart disease).
If any of the above apply to you, talk to your doctor for further instructions.
Stop taking Metformin 750mg Prolonged-Release Tablets for a short time if you have a condition that may be associated with dehydration (significant loss of body fluids) such as severe vomiting, diarrhoea, fever, exposure to heat or if you drink less fluid than normal. Talk to your doctor for further instructions.
Stop taking Metformin 750mg Prolonged-Release Tablets and contact a doctor or the nearest hospital immediately if you experience some of the symptoms of lactic acidosis, as this condition may lead to coma. Symptoms of lactic acidosis include: ■ vomiting, ■ stomach ache (abdominal pain), ■ muscle cramps, ■ a general feeling of not being well with severe tiredness, ■ difficulty in breathing, ■ reduced body temperature and heartbeat.
Lactic acidosis is a medical emergency and must be treated in a hospital.
If you need to have major surgery you must stop taking Metformin during and for some time after the procedure. Your doctor will decide when you must stop and when to restart your treatment with Metformin.
During treatment with Metformin, your doctor will check your kidney function at least once a year or more frequently if you are elderly and/or if you have worsening kidney function.
If you are older than 75 years, treatment with Metformin 750mg Prolonged-Release Tablets should not be started to lower the risk of developing type 2 diabetes.
You may see some remains of the tablets in your stools. Do not worry – this is normal for this type of tablet.
You should continue to follow any dietary advice that your doctor has given you and you should make sure that you eat carbohydrates regularly throughout the day.
Do not stop taking this medicine without speaking to your doctor.
Other medicines and Metformin 750mg Prolonged-Release Tablets If you need to have an injection of contrast medium that contains iodine into your bloodstream, for example in context of an X-ray or scan, you must stop taking Metformin before or at the time of injection. Your doctor will decide when you must stop and when to restart your treatment with Metformin.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. You may need more frequent blood glucose and kidney function tests, or your doctor may need to adjust the dosage of Metformin. It is especially important to mention the following:
- Steroids such as prednisolone, mometasone, beclometasone.
- Sympathomimetic medicines including epinephrine and dopamine used to treat heart attacks and low blood pressure. Epinephrine is also included in some dental anaesthetics.
- Medicines which increase urine production (diuretics (water tablets) such as furosemide).
- Certain medicines for the treatment of high blood pressure (ACE inhibitors and angiotensin II receptor antagonists).
- Medicines used to treat pain and inflammation (NSAID and COX-2-inhibitors, such as ibuprofen and celecoxib).
- Medicines that may change the amount of Metformin in your blood, especially if you have reduced kidney function (such as verapamil, rifampicin, cimetidine, dolutegravir, ranolazine, trimethoprim, vandetanib, isavuconazole, crizotinib, olaparib).
Metformin 750mg Prolonged-Release Tablets with food, drink and alcohol
The tablets should be swallowed whole with a glass of water during or immediately after meals.
Avoid excessive alcohol intake while taking Metformin since this may increase the risk of lactic acidosis (see section “Warnings and precautions”).
Pregnancy and breast-feeding
Do not take Metformin if you are pregnant or breast-feeding. If you 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
Metformin taken on its own does not cause ‘hypos’ (symptoms of low blood sugar or hypoglycaemia, such as faintness, confusion and increased sweating) and therefore should not affect your ability to drive or use machinery.
You should be aware; however, that Metformin taken with other antidiabetic medicines can cause hypos, so in this case you should take extra care when driving or operating machinery.

If you take more Metformin Prolonged-Release Tablets than you should
If you take extra tablets by mistake you need not worry, but if you have unusual symptoms, contact your doctor. If the overdose is large, lactic acidosis is more likely.
