Metformin Hydrochloride Information

Metformin (met for' min) Fortamet® Glucophage® Glumetza® Riomet® Actoplus Met® (as a combination product containing Metformin, Pioglitazone) Avandamet® (as a combination product containing Metformin, Rosiglitazone) Invokamet® (as a combination product containing Canagliflozin, Metformin) Janumet® (as a combination product containing Metformin, Sitagliptin) Jentadueto® (as a combination product containing Linagliptin, Metformin) Kazano® (as a combination product containing Metformin, Alogliptin) Kombiglyze® XR (as a combination product containing Metformin, Saxagliptin) Metaglip® (as a combination product containing Glipizide, Metformin)¶ Prandimet® (as a combination product containing Metformin, Repaglinide) Synjardy® (as a combination product containing Metformin, Empagliflozin) Xigduo® XR (as a combination product containing Dapagliflozin, Metformin) Metformin may rarely cause a serious, life-threatening condition called lactic acidosis. Tell your doctor if you have kidney disease. Your doctor will probably tell you not to take metformin. Also, tell your doctor if you are over 65 years old and if you have ever had a heart attack; stroke; diabetic ketoacidosis (blood sugar that is high enough to cause severe symptoms and requires emergency medical treatment); a coma; or heart or liver disease. Taking certain other medications with metformin may increase the risk of lactic acidosis. Tell your doctor if you are taking acetazolamide (Diamox), dichlorphenamide (Keveyis), methazolamide, topiramate (Topamax, in Qsymia), or zonisamide (Zonegran). Tell your doctor if you have recently had any of the following conditions, or if you develop them during treatment: serious infection; severe diarrhea, vomiting, or fever; or if you drink much less fluid than usual for any reason. You may have to stop taking metformin until you recover. If you are having surgery, including dental surgery, or any major medical procedure, tell the doctor that you are taking metformin. Also, tell your doctor if you plan to have any x-ray procedure in which dye is injected, especially if you drink or have ever drunk large amounts of alcohol or have or have had liver disease or heart failure. You may need to stop taking metformin before the procedure and wait 48 hours to restart treatment. Your doctor will tell you exactly when you should stop taking metformin and when you should start taking it again. If you experience any of the following symptoms, stop taking metformin and call your doctor immediately: extreme tiredness, weakness, or discomfort; nausea; vomiting; stomach pain; decreased appetite; deep and rapid breathing or shortness of breath; dizziness; lightheadedness; fast or slow heartbeat; flushing of the skin; muscle pain; or feeling cold, especially in your hands or feet. Tell your doctor if you regularly drink alcohol or sometimes drink large amounts of alcohol in a short time (binge drinking). Drinking alcohol increases your risk of developing lactic acidosis or may cause a decrease in blood sugar. Ask your doctor how much alcohol is safe to drink while you are taking metformin. Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests before and during treatment to check how well your kidneys are working and your body's response to metformin. Talk to your doctor about the risk(s) of taking metformin.

Metformin is used alone or with other medications, including insulin, to treat type 2 diabetes (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Metformin is in a class of drugs called biguanides. Metformin helps to control the amount of glucose (sugar) in your blood. It decreases the amount of glucose you absorb from your food and the amount of glucose made by your liver. Metformin also increases your body's response to insulin, a natural substance that controls the amount of glucose in the blood. Metformin is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood). Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.

Metformin comes as a liquid, a tablet, and an extended-release (long-acting) tablet to take by mouth. The liquid is usually taken with meals one or two times a day. The regular tablet is usually taken with meals two or three times a day. The extended-release tablet is usually taken once daily with the evening meal. To help you remember to take metformin, take it around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take metformin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Swallow metformin extended-release tablets whole; do not split, chew, or crush them. Your doctor may start you on a low dose of metformin and gradually increase your dose not more often than once every 1–2 weeks. You will need to monitor your blood sugar carefully so your doctor will be able to tell how well metformin is working. Metformin controls diabetes but does not cure it. Continue to take metformin even if you feel well. Do not stop taking metformin without talking to your doctor. Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.

Before taking metformin, tell your doctor and pharmacist if you are allergic to metformin, any of the ingredients of metformin liquid or tablets, or any other medications. Ask your pharmacist or check the manufacturer's patient information for a list of the ingredients. tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects. tell your doctor if you have or have ever had any medical condition, especially those mentioned in the IMPORTANT WARNING section. tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking metformin, call your doctor. tell your doctor if you eat less or exercise more than usual. This can affect your blood sugar. Your doctor will give you instructions if this happens.

Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. It is important to eat a healthful diet.

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

This medication may cause changes in your blood sugar. You should know the symptoms of low and high blood sugar and what to do if you have these symptoms. Metformin may cause side effects.
