Metaglip (glipizide and metformin HCl) is a combination of two oral diabetes medicines for people with type 2 diabetes who do not use daily insulin injections. This medication is not for treating type 1 diabetes. The brand name of this medication is discontinued, but generic versions may be available. Common side effects include nausea, diarrhea, stomach upset, muscle aches, or headache.

Dosage of Metaglip is individualized on the basis of both effectiveness and tolerance while not exceeding the maximum recommended daily dose of 20 mg glipizide/2000 mg metformin. Metaglip may interact with furosemide, nifedipine, cimetidine, ranitidine, amiloride, triamterene, digoxin, morphine, procainamide, quinidine, trimethoprim, vancomycin, or ketoconazole, or itraconazole. Hyperglycemia (high blood sugar) may result if you take Metaglip with isoniazid, diuretics, steroids, heart or blood pressure medications, niacin, phenothiazines, thyroid medicines, birth control pills and other hormones, seizure medicines, and diet pills or medicines to treat asthma, colds or allergies. Hypoglycemia (low blood sugar) may result if you take Metaglip with exenatide, probenecid, nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin or other salicylates, sulfa drugs, monoamine oxidase inhibitors (MAOIs), beta-blockers, or other diabetes medications. Tell your doctor all medications and supplements you use. During pregnancy, Metaglip should be used only when prescribed. Insulin treatment may be preferred during pregnancy. If you are using this drug during your pregnancy, your doctor may switch you to insulin at least 1 month before the expected delivery date because of Metaglip's risk of low blood sugar in your newborn. Consult your doctor and follow your doctor's instructions. This drug passes into breast milk and could have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.

Metaglip in Detail - Patient Information: Side Effects

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

This medication may cause lactic acidosis (a build-up of lactic acid in the body, which can be fatal). Lactic acidosis can start slowly and get worse over time. Get emergency medical help if you have even mild symptoms of lactic acidosis, such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, slow or uneven heart rate, dizziness, or feeling very weak or tired.

Stop taking this medication and call your doctor at once if you have a serious side effect such as:

  • feeling short of breath, even with mild exertion, swelling or rapid weight gain;
  • pain or burning with urination;
  • nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes); or
  • dangerously high blood pressure (severe headache, blurred vision, buzzing in your ears, anxiety, confusion, chest pain, shortness of breath, uneven heartbeats, seizure).

Less serious side effects may include:

  • cold symptoms such as stuffy nose, sneezing, sore throat;
  • headache, dizziness;
  • mild nausea, vomiting, diarrhea, stomach pain; or
  • joint or muscle pain.

What is Patient Information Overview?

Metaglip Overview - Patient Information: Side Effects

SIDE EFFECTS: See also Warning section.

Nausea, diarrhea, stomach upset, muscle aches, or headache may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. If stomach symptoms return later (after you are on the same dose for several days or weeks), tell your doctor immediately. Stomach symptoms that occur after the first days of your treatment may be a sign of lactic acidosis.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: easy bleeding/bruising, signs of infection (e.g., persistent sore throat, fever), persistent nausea, severe stomach/abdominal pain, yellowing eyes/skin, dark urine.

This medication may cause low blood sugar (hypoglycemia), especially if you take other medications for diabetes, drink large amounts of alcohol, do unusually heavy exercise, or do not consume enough calories from food. Symptoms include cold sweat, blurred vision, dizziness, drowsiness, shaking, fast heartbeat, headache, fainting, tingling of the hands/feet, and hunger. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor about the reaction immediately. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.

Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor immediately. Your dosage may need to be increased.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

 Hypoglycemia

In a controlled initial therapy trial of METAGLIP (glipizide and metformin) 2.5 mg/250 mg and 2.5 mg/500 mg the numbers of patients with hypoglycemia documented by symptoms (such as dizziness, shakiness, sweating, and hunger) and a fingerstick blood glucose measurement ≤ 50 mg/dL were 5 (2.9%) for glipizide, 0 (0%) for metformin, 13 (7.6%) for METAGLIP (glipizide and metformin) 2.5 mg/250 mg, and 16 (9.3%) for METAGLIP (glipizide and metformin) 2.5 mg/500 mg. Among patients taking either METAGLIP (glipizide and metformin) 2.5 mg/250 mg or METAGLIP (glipizide and metformin) 2.5 mg/500 mg, 9 (2.6%) patients discontinued METAGLIP (glipizide and metformin) due to hypoglycemic symptoms and 1 required medical intervention due to hypoglycemia. In a controlled second-line therapy trial of METAGLIP (glipizide and metformin) 5 mg/500 mg, the numbers of patients with hypoglycemia documented by symptoms and a fingerstick blood glucose measurement ≤ 50 mg/dL were 0 (0%) for glipizide, 1 (1.3%) for metformin, and 11 (12.6%) for METAGLIP (glipizide and metformin) . One (1.1%) patient discontinued METAGLIP (glipizide and metformin) therapy due to hypoglycemic symptoms and none required medical intervention due to hypoglycemia. (See PRECAUTIONS.)

Gastrointestinal Reactions

Among the most common clinical adverse events in the initial therapy trial were diarrhea and nausea/vomiting; the incidences of these events were lower with both METAGLIP (glipizide and metformin) dosage strengths than with metformin therapy. There were 4 (1.2%) patients in the initial therapy trial who discontinued METAGLIP (glipizide and metformin) therapy due to gastrointestinal (GI) adverse events. Gastrointestinal symptoms of diarrhea, nausea/vomiting, and abdominal pain were comparable among METAGLIP (glipizide and metformin) , glipizide and metformin in the second-line therapy trial. There were 4 (4.6%) patients in the second-line therapy trial who discontinued METAGLIP (glipizide and metformin) therapy due to GI adverse events.
