Vistide and Norvir drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Vistide (cidofovir) and Norvir (ritonavir). Common drug interactions include vulvitis among females and blood creatinine increased among males.

The phase IV clinical study analyzes what interactions people have when they take Vistide and Norvir. It is created by eHealthMe based on reports of 19 people who take the same drugs from the FDA, and is updated regularly.
