Diabeta side effects, that may go away during treatment, include nausea, heartburn, stomach fullness, or weight gain. If Diabeta side effects continue or are bothersome, check with your doctor. CONTACT YOUR DOCTOR IMMEDIATELY if you experience Diabeta side effects like persistent sore throat or fever, easy bleeding/bruising, stomach pain, yellowing eyes or skin, dark urine, unusual tiredness or weakness, unusual or sudden weight gain, mental/mood changes, swelling of the hands or feet, or seizures. Diabeta side effects CAN CAUSE LOW BLOOD SUGAR (hypoglycemia). This effect may occur if you do not consume enough calories (from food, juices, fruit, etc). Diabeta side effects include chills, cold sweat, blurred vision, 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 do not 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 Diabeta side effects. To 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 medicine dosage may need to be increased. Diabeta side effects are unlikely, but seek immediate medical attention if Diabeta side effects occur. Symptoms of Diabeta side effects include rash, itching, swelling, dizziness, or trouble breathing. If you notice other Diabeta side effects not listed above, contact your doctor, nurse, or pharmacist.
