Periactin and Claritin drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Periactin (cyproheptadine hydrochloride) and Claritin (loratadine). Common drug interactions include dry skin among females and abnormal behaviour among males.
The phase IV clinical study analyzes what interactions people have when they take Periactin and Claritin. It is created by eHealthMe based on reports of 46 people who take the same drugs from the FDA, and is updated regularly.
