Periactin and Zantac drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Periactin (cyproheptadine hydrochloride) and Zantac (ranitidine hydrochloride). Common drug interactions include organ failure among females and cough among males.

The phase IV clinical study analyzes what interactions people have when they take Periactin and Zantac. It is created by eHealthMe based on reports of 79 people who take the same drugs from the FDA, and is updated regularly.
