### Human:\ncan inderal and an antihistamine be taken together?\n\n### Assistant: antihistamines are safe to take while using inderal; there are not any known interactions. however inderal does make some people drowsy and certain over-the-counter antihistamines can make you drowsy as well. so i would suggest if you buy an antihistamine that does not cause drowsiness such as loratadine. your pharmacist can help you find one that is best for you.
