Metformin tablets

What do metformin tablets do?
METFORMIN (Glucophage(R)) is a medicine used to treat Type II diabetes (formerly called non-insulin-dependent diabetes). Treatment is combined with a balanced diet and exercise. This medicine lowers blood sugar and helps your body to use insulin more efficiently. It is sometimes used with other medicines for diabetes.

What should my health care professional know before I take metformin?
They need to know if you have any of these conditions:

• become easily dehydrated
• heart attack
• heart failure that is treated with medications
• hormone changes or problems
• kidney disease
• liver disease
• polycystic ovaries
• serious infection or injury
• thyroid disease
• undergoing surgery or certain x-ray procedures with injectable contrast agents
• an unusual or allergic reaction to metformin, other medicines, foods, dyes, or preservatives
• pregnant or trying to get pregnant
• breast-feeding

How should I take this medicine?
Take metformin tablets by mouth, with meals. Follow the directions on the prescription label. Swallow the tablets with a drink of water. Take your doses at regular intervals. Do not take your medicine more often than directed.

Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed.

What if I miss a dose?
