Metformin: Uses, Side Effects & Brands in Pakistan
Metformin is usually the first tablet doctors prescribe for type 2 diabetes. It is available as standard and extended-release tablets, and in many combination tablets with other diabetes medicines. Glucophage is one of the best-known brands in Pakistan.
How Metformin works
Metformin lowers the amount of sugar the liver releases into the blood and helps the body respond better to its own insulin. On its own it rarely causes low blood sugar.
What is Metformin used for?
- Type 2 diabetes, together with diet and exercise
- Combined with other diabetes medicines or insulin when one medicine is not enough
Doctors also prescribe metformin for some women with polycystic ovary syndrome (PCOS).
Side effects of Metformin
Stomach side effects are common at first and often settle after a few weeks. Taking it with food, or switching to an extended-release tablet, can help. Side effects include:
- Nausea, diarrhoea or stomach upset, mainly when starting
- Loss of appetite
- A metallic taste
- Lower vitamin B12 levels with long-term use
A rare but serious side effect is lactic acidosis. Get medical help urgently if you feel very weak or tired, have muscle pain, trouble breathing, stomach pain with vomiting, or feel cold and dizzy.
Precautions and warnings
- Your doctor will check your kidney function before and during treatment.
- You may need to stop it for a short time before surgery or an X-ray scan with contrast dye. Your doctor will advise you.
- If you have severe vomiting, diarrhoea or dehydration, contact your doctor, as you may need to pause it.
- Avoid heavy alcohol use.
- Tell your doctor if you are pregnant or planning a pregnancy.
