Product Information


Metfor is used for the treatment of type 2 diabetes mellitus, when diet and exercise are not enough to control blood glucose levels. This drug contains 500mg of the active ingredient Metformin hydrochloride. Type 2 diabetes mellitus is a form of diabetes characterized by having high blood sugar. Either the body doesn’t produce enough insulin or the body produces insulin but does not react properly to the hormone. The hormone insulin is responsible for converting the glucose from the food intake into energy.  Metfor may be used alone or with other antidiabetic drugs like sulphonylureas and insulin, together with proper diet and exercise, in managing diabetes. Metfor is also used in treating Polycystic Ovary Syndrome (PCOS).


Metformin improves glucose tolerance in patients with diabetes by decreasing intestinal absorption of glucose, decreasing glucose production by the liver, and improves sensitivity to insulin by increasing insulin uptake and utilization in muscles and adipose tissues.




Metfor 500 is manufactured by Cipla Limited




The recommended initial adult dose of Metfor is 500mg orally twice daily or 850 mg orally once daily. The dose is then increased to 500mg weekly or 850mg every 2 weeks as tolerated and based on the response of blood glucose levels. The maintenance dose is 2000mg daily and the maximum daily dose is 2550mg daily in 3 divided doses. The dose is gradually increased to reduce gastrointestinal side effects.


The recommended initial pediatrics dose for children aged 10years and above, is 500mg orally twice daily. The dose may also be gradually increased to 500mg weekly. Maintenance dose can reach up to the maximum dose of 2000mg daily in divided doses.


For the treatment of PCOS, the recommended dose is 1000mg twice daily.


Metfor tablets are taken by mouth, swallowed whole and taken with meals.


Note that the above dosages serve as guidelines only. Not all diabetes patients have the same dosage. A physician must be consulted to get the right dosage. 




Patients allergic to the active ingredient Metformin hydrochloride, all inactive ingredients of the tablet, and allergy to any biguanides must not take Metfor.


Metfor is also contraindicated to patients with severe kidney problems and with a history or in a current state of diabetic ketoacidosis.

Low blood sugar (hypoglycemia) can occur in patients taking Metformin when calorie intake is inadequate, calorie supplementation is inadequate after a vigorous exercise, concomitant use with other glucose lowering drugs and alcohol consumption. Symptoms of low blood sugar include sudden sweating, hunger, fast heartbeat, blurred vision, dizziness, shaking, or tingling of hands and feet.
