Call your doctor right away if you have chest pain or discomfort, nausea, pain or discomfort in the arms, jaw, back, or neck, shortness of breath, sweating, or vomiting. These may be symptoms of a heart attack.

If you are rapidly gaining weight or having shortness of breath, chest pain or discomfort, extreme tiredness or weakness, irregular breathing, irregular heartbeat, or excessive swelling of the hands, wrist, ankles, or feet, check with your doctor right away. These may be symptoms of a heart problem or edema (fluid retention).

If you have abdominal or stomach pain, dark urine, a loss of appetite, nausea or vomiting, unusual tiredness or weakness, or yellow eyes or skin, check with your doctor right away. These may be symptoms of a serious liver problem.

Check with your doctor right away if blurred vision, difficulty in reading, or any other change in vision occurs while you are taking rosiglitazone. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).

rosiglitazone may increase the risk for bone fractures in women. Ask your doctor about ways to keep your bones strong to help prevent fractures.

Certain women may be at an increased risk for pregnancy while taking rosiglitazone. If you had problems ovulating and had irregular periods in the past, rosiglitazone may cause you to ovulate. This could increase your chance of becoming pregnant. If you are a woman of childbearing potential, you should discuss birth control options with your doctor.

Make sure any doctor or dentist who treats you knows that you are using rosiglitazone. rosiglitazone may affect the results of certain medical tests.

It is very important to carefully follow any instructions from your doctor about:

  • Alcohol—Drinking alcohol may cause severe low blood sugar. Discuss this with your doctor.
  • Other medicines—Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems.
  • Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, diabetic patients may need special counseling about diabetes medicine dosing changes that might occur because of lifestyle changes, such as changes in exercise and diet. Furthermore, counseling on contraception and pregnancy may be needed because of the problems that can occur in patients with diabetes during pregnancy.
  • Travel—Keep 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.
  • In case of emergency—There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says that you have diabetes and a list of all of your medicines.
  • Symptoms of fluid retention—Know what to do if you start to retain fluid. Fluid retention may worsen or lead to heart problems.

rosiglitazone does not cause hypoglycemia (low blood sugar). However, low blood sugar can occur if you delay or miss a meal or snack, exercise more than usual, drink alcohol, cannot eat because of nausea or vomiting, or take rosiglitazone with another type of diabetes medicine. The symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people feel different symptoms of low blood sugar. It is important that you learn which symptoms of low blood sugar you usually have so that you can treat it quickly.

  • Symptoms of low blood sugar include anxiety, behavior change similar to being drunk, blurred vision, cold sweats, confusion, cool, pale skin, difficulty in thinking, drowsiness, excessive hunger, fast heartbeat, headache (continuing), nausea, nervousness, nightmares, restless sleep, shakiness, slurred speech, or unusual tiredness or weakness.
  • If symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes, or drink fruit juice, non-diet soft drinks, or sugar dissolved in water to relieve the symptoms. Also, check your blood for low blood sugar. Glucagon is used in emergency situations when severe symptoms such as seizures (convulsions) or unconsciousness occur. Have a glucagon kit available, along with a syringe and needle, and know how to use it. Members of your family also should know how to use it.

Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your medicine, overeat or do not follow your meal plan, have a fever or infection, or do not exercise as much as usual.

  • Symptoms of high blood sugar include blurred vision, drowsiness, dry mouth, flushed, dry skin, fruit-like breath odor, increased urination (frequency and amount), ketones in the urine, loss of appetite, sleepiness, stomachache, nausea, or vomiting, tiredness, troubled breathing (rapid and deep), unconsciousness, or unusual thirst.
