GLIPIZIDE/METFORMIN - ORAL

(GLIP-eh-zide/met-FOR-min)

COMMON BRAND NAME(S): Metaglip

WARNING: The metformin in this combination medication can rarely cause a condition called lactic acidosis, which can be fatal. If you develop any of the following symptoms of lactic acidosis, stop this medication and seek immediate medical attention: unusual tiredness (fatigue) or severe drowsiness, low body temperature, unexplained muscle pain, breathing trouble or rapid breathing, unusually slow or irregular heartbeat. Lactic acidosis is more likely to occur in patients who have: kidney or liver disease, conditions that may cause a low oxygen blood level or poor circulation (e.g., severe congestive heart failure, recent heart attack, recent stroke), excessive alcohol use, a lack of body fluids (dehydration), x-ray or scanning procedures that require an injectable iodinated contrast drug, surgery, or a serious infection. Also at higher risk are those who are elderly, especially if you are over 80 years of age and have not had kidney and liver tests.

Uses

This combination medication is used along with a diet and exercise program to control high blood sugar in diabetic patients. This medication works by releasing more of the insulin that your body naturally produces into your bloodstream and by helping your body use the insulin more effectively. Controlling high blood sugar helps prevent heart disease, strokes, kidney disease, blindness and circulation problems, as well as sexual function problems (impotence).

How To Use

Take this medication with meals. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. Your dosage is based on your medical condition and response to therapy. Read the patient information leaflet provided by your pharmacist. If you have any questions regarding the information, ask your doctor or pharmacist.

Side Effects

Also see Warnings. Nausea, stomach upset, diarrhea, vomiting or metallic taste may occur initially as your body adjusts to the medication. If stomach symptoms recur later (after you are on the same dose for several days or more), tell your doctor immediately. A late recurrence of stomach symptoms may be due to lactic acidosis. Headache, back pain, joint pain, weight gain, increased sensitivity to sunlight, cough or fever may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Tell your doctor immediately if any of these unlikely but serious side effects occur: unusual tiredness or weakness, trouble breathing. Tell your doctor immediately if any of these highly unlikely but very serious side effects occur: stomach pain, yellowing eyes or skin, dark urine, unusual bleeding or bruising, persistent sore throat or fever, unusual change in the amount of urine. This medication can cause low blood sugar (hypoglycemia). The symptoms include chills, cold sweat, dizziness, drowsiness, shaking, rapid heart rate, weakness, headache, fainting, tingling of the hands or feet, or hunger. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you are in a situation where you don't have these reliable forms of glucose, eat a quick source of sugar such as table sugar, honey, or candy, or drink a glass of orange juice or non-diet soda to quickly raise your blood sugar level. Tell your doctor immediately about the reaction. To help prevent hypoglycemia, eat meals on a regular schedule and do not skip meals. Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, or fruity breath odor. If these symptoms occur, tell your doctor immediately. Your medication dosage may need to be increased. An allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of an allergic reaction include: rash, itching, swelling, dizziness, trouble breathing. If you notice other effects not listed above, contact your doctor or pharmacist.
