Accolate and Demerol drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Accolate (zafirlukast) and Demerol (meperidine hydrochloride). Common drug interactions include injury among females and abdominal distension among males.

The phase IV clinical study analyzes what interactions people have when they take Accolate and Demerol. It is created by eHealthMe based on reports of 21 people who take the same drugs from the FDA, and is updated regularly.
