MedlinePlus advises patients to take carvedilol exactly as directed by a doctor even if they are feeling well.

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.
