Metformin.

Metformin is often recommended for the treatment of type 2 diabetes and works by controlling the amount of glucose in your blood. This drug comes as a tablet intended for oral administration and is supposed to be taken two or three times a day with meals. If you have been prescribed the extended-release pill you will need to be taking it once a day in the evening (also with a meal). Make sure you let your doctor know if you have any medical conditions that need to be taken into consideration when prescribing metformin. Also let your doctor know if you are taking such drugs as nicotinic acid, ranitidine, phenytoin, medications for thyroid disease, furosemide, insulin or other medications for diabetes, oral contraceptives, medications for asthma and colds, beta-blockers, oral steroids, cimetidine, quinidine, quinine, antihistamines, isoniazid, or calcium channel blockers, as those may interact with the effects of metformin . Side effects are possible and can include heartburn, sneezing, bloating, diarrhea, headache, runny nose, metallic taste in mouth, flushing of the skin, stomach pain, gas, constipation, cough, and muscle pain. You can continue with the treatment if you get any of the side effects mentioned.
