Interaction with Foods and Other Compounds

Food
Taking carvedilol with food slows the speed, but not the overall extent of absorption of the drug. Though taking carvedilol with food does not reduce the effectiveness of the drug, it might reduce the incidence of a common side effect known as orthostatic hypotension.¹ Therefore, people should take carvedilol with a meal.

Salt restriction
In one controlled clinical trial, lowering dietary salt intake increased the fall in blood pressure obtained with carvedilol.² Therefore, people taking carvedilol to treat high blood pressure should consider eating a diet low in salt to improve the outcome of drug therapy.
