SIDE EFFECTS: The most common side effects of carvedilol are:
- edema (fluid accumulation),
- decreased heart rate,
- diarrhea and
- postural hypotension (a rapid decrease in blood pressure when going from the seated to the standing position that causes lightheadedness and/or fainting).
Taking carvedilol with food minimizes the risk of postural hypotension.
Other common side effects of carvedilol are irregular heart rhythm, and abnormalities of vision.
Carvedilol should be used cautiously in patients who use diuretics or who are elderly or have cirrhosis, asthma, peripheral vascular disease, hyperthyroidism, Prinzmetal's variant angina (angina at rest), or kidney disease.
GENERIC AVAILABLE: yes
- Tablets: 3.125, 6.25, 12.5, and 25 mg.

STORAGE: Tablets should be stored at room temperature, 15 C and 30 C (59 F and 86 F).
DOSING: Carvedilol tablets are usually given twice daily. For high blood pressure, the dose is 6.25 mg twice daily to a maximum of 25 mg twice daily.
For congestive heart failure, the dose is 3.25 mg twice daily to a maximum of 25 mg twice daily. A maximum dose of 50 mg twice daily has been used in persons weighing more than 85 kg (187 pounds).
Carvedilol should be taken with food to slow its absorption and reduce the occurrence of low blood pressure when rising from a sitting or sleeping position (orthostatic hypotension). Stopping and changing doses of carvedilol should be done under the direction of a physician since sudden changes in dose can result in serious cardiac complications such as arrhythmias.
