OWhat Bolamyn SR 500 mg
Metformin, active substance of Bolamyn SR 500mg Prolonged Release Tablets, belongs to a group of active substances called biguanides, which are used to treat diabetes by regulating the level of sugar in the blood.
• Bolamyn SR is used for patients who have non-insulin-dependent (type 2) diabetes, particularly in overweight patients, where diet and exercise alone have failed to control it. Metformin can be given alone or in combination with other oral antidiabetic medicines or with insulin.
This is a prolonged release tablet which a type of tablet that spreads the release of the medication over a longer period of time than an immediate release tablet. Ask your doctor or pharmacist if you need additional information.

Warnings and Precautions
Talk to your doctor or pharmacist before taking Bolamyn SR Tablets Bolamyn SR treatment may rarely cause a serious condition called lactic acidosis which requires urgent hospital treatment to prevent it leading to coma. Other
illnesses, prolonged fasting, poor blood sugar control, or alcohol intake can all increase the risk of lactic acidosis developing. You should be aware of the warning symptoms which include muscle cramps, abdominal pain, breathlessness and a feeling of being very weak and unwell. If you develop these symptoms you must tell your doctor immediately.
• Your doctor should check that your kidneys are working properly at least once a year or more often if needed
• If you are going to have an anaesthetic, X-ray or scan, tell your doctor that you are taking Bolamyn SR. It is advised to stop taking Bolamyn SR for 48 hours before and after the procedure
• Continue to follow any dietary advice your doctor has given you and get some regular exercise while you are taking this medicine
• Be careful if you are taking Bolamyn SR with insulin or other antidiabetic medicines, as the combination may increase the risk of hypoglycaemia ("hypos", excessively low sugar in your blood)
• Children and adolescents should not take Bolamyn SR.
Other medicines and Bolamyn SR Tablets
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
• Bolamyn SR must not be used at the same time as some injectable dyes used for certain kinds of X-rays or scans, because there is a risk of kidney failure. If you are going to undergo these procedures, you must tell your doctor you are taking Bolamyn SR. It is advised to stop taking Bolamyn SR for 48 hours before and after the procedure.
• Glucocorticoids (e.g. budesonide, beclomethasone or hydrocortisone, which are sometimes used to suppress inflammation caused by allergic reactions and in asthma), beta-2-agonists (e.g. salbutamol, which are mostly used in the treatment of asthma) and diuretics (water tablets which increase urine production and may be used to treat high blood pressure) can all increase blood sugar levels. You should check your blood sugar more often if you are taking Bolamyn SR with any of these medicines.
• ACE (Angiotensin Converting Enzyme) inhibitors (e.g. quinapril, captopril, which are used to treat heart problems) can reduce blood sugar levels. Tell your doctor if you start treatment with an ACE inhibitor.
• Be careful and tell your doctor if you start treatment for high blood pressure or start to take a diuretic (water tablets which increase urine production) or NSAID (non-steroidal anti-inflammatory drugs, e.g. ibuprofen) as you may be at increased risk for kidney problems.
Bolamyn SR Tablets with food and drink
• Bolamyn SR must be taken during or after your evening meal. Taking your tablets with food can reduce unwanted side effects.
• You must avoid consuming alcohol and using alcohol-containing medicines whilst on Bolamyn SR, as you could be at greater risk of developing lactic acidosis, a serious complication which can be recognised by muscle cramps, abdominal pain, breathlessness and a feeling of being very weak and unwell.
