Fortamet is a hypoglycemic agent used alone or in combination with other oral antidiabetic drugs for the treatment of hyperglycemia caused by type 2 diabetes. Insulin produced by the pancreas cannot facilitate sugar into the cells of the body in type 2 diabetes. Type 2 diabetes can be controlled with diet and exercise.
The amount of metformin you take must be balanced against the amount and type of food you eat and the amount of exercise you do in order for the drug to work.
This drug will not work on type 1 diabetes due to the inability of pancreas to secret insulin. Insulin injections are required for type 1 diabetes. This drug requires a prescription.

4 Precautions to Take
In using Fortamet, you must be careful and take some precautions as advised by your doctor.
Regular visits should be made to your healthcare provider to track your progress and to monitor the effectiveness and unwanted effects of the drug. Unwanted effects can be screened using blood and urine tests. The dye used for an X-ray or CT scan may be affected by this drug.
You will be advised to stop taking this drug before having any medical exams or diagnostic tests that might cause less urine output than usual. You may be advised to start taking the drug again 48 hours after the exams or tests if your kidney function is tested and found to be normal. Inform any healthcare professional or dentist that you are using this drug, as you may need to stop using this drug several days before having surgery or medical tests. Hypoglycemia may be caused by alcohol intake.
Discuss this with your health care team. Consult with your healthcare professional before you take other drugs such as nonprescription drugs such as aspirin, and drugs for appetite control, asthma, colds, cough, hay fever, or sinus problems. Patients with diabetes may need special counseling about diabetes drug dosing changes that might occur with lifestyle changes, such as changes in exercise or diet.
The problems that can occur in pregnancy for patients with diabetes may require counseling on birth control and pregnancy. Always carry a recent prescription and your medical history with you. Be prepared for an emergency as you would normally. Make allowances for changing time zones and keep your meal times as close as possible to your usual meal times.
Emergency help may be needed for complications caused by your diabetes. You need to be prepared for these emergencies. It is recommended to wear a medical identification bracelet or neck chain, and an ID card in your wallet or purse that says that you have diabetes and a list of all of your drugs.
Lactic acidosis has been associated with excessive use of metformin under certain conditions. Consult with your healthcare professional if you have symptoms of lactic acidosis such as a heart attack or kidney failure, abdominal or stomach discomfort, decreased appetite, diarrhea, fast or shallow breathing, a general feeling of discomfort, severe muscle pain or cramping, and unusual sleepiness, tiredness, or weakness.
Taking this drug can cause hypoglycemia, which can also occur if you delay or miss a meal or snack, drink alcohol, exercise more than usual, cannot eat because of nausea or vomiting, take certain drugs, or take metformin with another type of diabetes drug. Hypoglycemia must be treated before they lead to unconsciousness.
Seek immediate medical attention if you experience symptoms of hypoglycemia such as anxiety, behavior change similar to being drunk, blurred vision, cold sweats, confusion, cool, pale skin, difficulty with thinking, drowsiness, excessive hunger, fast heartbeat, headache, nausea, nervousness, nightmares, restless sleep, shakiness, slurred speech, or unusual tiredness or weakness.
It is recommended to eat glucose tablets or gel, corn syrup, honey, or sugar cubes, or drink fruit juice, non-diet soft drink, or sugar dissolved in water if these symptoms occur. In emergency situations glucagon is used to treat severe symptoms such as seizures or unconsciousness. It is recommended to have a glucagon kit available, along with a syringe or needle, and know how to use it.
The members of your household also should know how to use it. Uncontrolled diabetes can lead to hyperglycemia. Consult with your healthcare professional if you have symptoms of hyperglycemia such as blurred vision, drowsiness, dry mouth, flushed, dry skin, fruit-like breath odor, increased urination, ketones in the urine, loss of appetite, sleepiness, stomachache, nausea or vomiting, tiredness, troubled breathing, unconsciousness, or unusual thirst. Hyperglycemia happens if you do not exercise as much as usual, have a fever or infection, do not take enough or skip a dose of your diabetes drug, or overeat or do not follow your meal plan.
Check your blood sugar level and then call your healthcare professional for instructions if hyperglycemia occurs. This drug is only part of a complete program for controlling diabetes. It is recommended to always eat a healthy diet, monitor your weight, and get regular exercise.
