Prinzide and Leflunomide drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Prinzide (hydrochlorothiazide; lisinopril) and Leflunomide (leflunomide). Common drug interactions include asthenia among females and joint effusion among males.

The phase IV clinical study analyzes what interactions people have when they take Prinzide and Leflunomide. It is created by eHealthMe based on reports of 15 people who take the same drugs from the FDA, and is updated regularly.
