Is carvedilol a beta-blocker or diuretic?

Carvedilol belongs to a class of drugs called beta-blockers. It is not a diuretic (water pill).



How long does it take for carvedilol to work?

If you are taking carvedilol for high blood pressure, it may take 7-14 days to see its full effects. Contact your doctor if you don’t see any improvement in your blood pressure readings after 1-2 weeks of carvedilol use.

Carvedilol may increase potassium levels in the body. Your doctor may advise you to avoid high-potassium foods like bananas, avocados, and green leafy vegetables while on this medicine.

Alcohol and caffeine can both affect carvedilol. Caffeine can prevent carvedilol from working properly, so it is best to avoid coffee while taking this medicine.
