Diazepam and Stelazine drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Diazepam (diazepam) and Stelazine (trifluoperazine hydrochloride). Common drug interactions include abnormal dreams among females and insomnia among males.

The phase IV clinical study analyzes what interactions people have when they take Diazepam and Stelazine. It is created by eHealthMe based on reports of 60 people who take the same drugs from the FDA, and is updated regularly.
