Avandamet oral Warnings
The rosiglitazone in this medication may infrequently cause or worsen certain heart problems (congestive heart failure, heart attack). Seek immediate medical attention if you notice any symptoms of heart problems, including: swelling of the hands/feet, unusual/sudden weight gain, trouble breathing, chest pain/discomfort.
The metformin in this combination medication can rarely cause a condition called lactic acidosis, which can be fatal. Seek immediate medical attention if you develop any of the following symptoms of lactic acidosis: unusual tiredness, severe drowsiness, cold skin, muscle pain, rapid/difficult breathing, unusually slow/irregular heartbeat.
Lactic acidosis is more likely to occur in patients who have: serious infection, surgery, kidney or liver disease, conditions that may cause a low level of oxygen in the blood or poor circulation (e.g., severe congestive heart failure, recent heart attack or stroke), excessive alcohol use, a lack of body fluids (dehydration), X-ray or scanning procedures that require an injectable iodinated contrast drug. The elderly are also at a higher risk, especially people over 80 who have not had kidney and liver tests.
Avandamet oral Uses
This combination medication is used along with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes (non-insulin-dependent diabetes). This medication works by helping to restore your body's proper response to the insulin you naturally produce.
You should only begin taking rosiglitazone/metformin when other drugs have not worked well or cannot be taken, and you do not wish to take pioglitazone-containing medications. If you are currently taking rosiglitazone/metformin and have good control of your blood sugars and no new side effects/symptoms, continue to take this medication as directed. Ask your doctor promptly about the risks and benefits of it, since a small number of people have had serious side effects (see Warning Section).
After November 18, 2011, only patients enrolled in the Avandia-Rosiglitazone Medicines Access Program may obtain and use rosiglitazone-containing products. Your doctor will need to register you with this program before you can receive your prescription. Only physicians enrolled in the Avandia-Rosiglitazone Medicines Access Program may prescribe rosiglitazone-containing products, and only certified mail-order pharmacies enrolled in the program may dispense them. Talk to your doctor or pharmacist for more details about the program.
Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Rosiglitazone belongs to a class of drugs known as thiazolidinediones or "glitazones." Metformin is a biguanide-type drug.How to use Avandamet oral

Take this medication by mouth, usually once or twice daily with a meal or as directed by your doctor.
The dosage is based on your medical condition and response to therapy. Taking more than 8 milligrams of rosiglitazone per day, or more than 2000 milligrams of metformin per day, is not recommended unless your doctor directs otherwise.
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.
Avandamet oral Side Effects
See also Warning section.
Nausea, stomach upset, diarrhea and metallic taste may occur at the beginning of treatment as your body adjusts to the medication. If stomach symptoms return later (after you are on the same dose for several days or more), tell your doctor immediately. Returning stomach symptoms may be due to 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 immediately if this unlikely but serious side effect occurs: bone fracture.
Seek immediate medical attention if any of these rare but very serious side effects occur: vomiting, stomach pain, yellowing eyes/skin, dark urine, vision changes (e.g., color or night vision problems).
This medication usually does not cause low blood sugar (hypoglycemia), but this effect may occur if you do not consume enough calories (from food, juices, fruit, etc.). The symptoms include chills, cold sweat, dizziness, drowsiness, shaking, rapid heart rate, weakness, headache, fainting, tingling of the hands/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, and fruity breath odor. If these symptoms occur, tell your doctor immediately. Your medication dosage may need to be increased.
A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: 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.

Avandamet oral Precautions
Before taking rosiglitazone/metformin, tell your doctor or pharmacist if you are allergic to it; or to other "glitazones" such as pioglitazone; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Promptly talk with your doctor or pharmacist about the benefits and possible risks of this medication, even if you have been taking it for awhile, especially if you have heart problems. Do not stop taking it unless directed to do so.
This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: kidney disease, history of 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), lack of body fluids (dehydration), serious infection, metabolic acidosis (e.g., diabetic ketoacidosis), type 1 diabetes (insulin-dependent diabetes).
Before using this medication, tell your doctor or pharmacist your medical history, especially of: severe breathing problems (e.g., obstructive lung disease, severe asthma), heart disease (e.g., chronic congestive heart failure, heart attack, angina), blood problems (e.g., anemia, vitamin B-12 deficiency), swelling (edema), fertility problems (e.g., ovulation problems), high cholesterol, upcoming surgery, alcohol use, eye (retina) problems, bone problems (e.g., osteoporosis, osteopenia).
You may experience blurred vision, dizziness, or drowsiness due to extremely low or high blood sugar levels. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely.
Limit alcohol while taking this medication because it can increase the risk of developing low blood sugar.
During times of stress, such as fever, infection, injury or surgery, it may be more difficult to control your blood sugar. Consult your doctor, as a change in your medication or how often you test your blood sugar may be required.
This medication may increase the risk of bone fracture (upper arm, hand, foot) in female patients. To lower the chance of getting injured, use caution when doing activities such as contact sports.
Kidney function declines as you grow older. The metformin in this product is removed by the kidneys. Therefore, elderly people may be at a greater risk for low blood sugar and lactic acidosis while using this drug.
Children may be more sensitive to the effects of this drug, especially low blood sugar.
This medication can cause changes in the menstrual cycle (promote ovulation) in women with certain fertility problems, increasing the risk of becoming pregnant. Consult your doctor or pharmacist about the use of reliable birth control while using this medication.

Avandamet oral Interactions
Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first.
Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: birth control pills, calcium channel blockers (e.g., nifedipine), cephalexin, cimetidine, corticosteroids (e.g., prednisone), decongestants, insulin, estrogens, gemfibrozil, herbal products (e.g., fenugreek, Gymnema, ginseng), isoniazid, niacin, phenothiazines (e.g., chlorpromazine), phenytoin, quinolone antibiotics (e.g., ciprofloxacin), rifampin, thyroid drugs, "water pills" (diuretics such as hydrochlorothiazide, furosemide).
Beta-blocker medications (e.g., metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar level falls too low (hypoglycemia). Other symptoms of low blood sugar such as dizziness, hunger, or sweating are unaffected by these drugs.
Many drugs can affect your blood sugar levels, making it more difficult to control your blood sugar. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar. Check your blood sugar levels regularly as directed by your doctor. Tell your doctor about the results and of any symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your anti-diabetic medication, exercise program, or diet.
