In brief: Hives
Cyproheptadine (aka periactin) is an older antihistamine that is often used to control chronic hives, especially hive caused by exposure to heat a condition called cholinergic urticaria.
This antihistamine commonly causes drowsiness, slowed reaction times and weight gain. In fact, it has been used, at times, as an appetite stimulant.
