MedlinePlus advises patients to take carvedilol exactly as directed by a doctor even if they are feeling well. It is best for patients to consult with their doctor before stopping carvedilol, as suddenly stopping this medication can result in serious heart problems, including chest pain, heart attack or an irregular heart rhythm.
Potential side effects of carvedilol include headache, diarrhea, nausea, vomiting, vision changes, difficulty sleeping and a cough, according to MedlinePlus. Dry eyes, joint pain, and numbness, burning or tingling in the arms or legs may also occur. Patients should notify their doctor if any of these side effects are severe or unrelieved. Because carvedilol can cause tiredness, weakness, lightheadedness and dizziness, it is best for patients to avoid driving or operating heavy machinery until they know how carvedilol affects them. Patients should contact their doctor immediately if they experience symptoms of high blood sugar, such as extreme hunger or thirst, blurred vision and frequent urination. Other serious side effects, including shortness of breath, swelling, hives, itching, slow or irregular heartbeat, and fainting, require immediate medical attention.Learn more about Medications & Vitamins
