Summary:

Drug interactions are reported among people who take Vistide (cidofovir) and Methotrexate (methotrexate sodium). Common drug interactions include disease recurrence among females and stomatitis among males.

The phase IV clinical study analyzes what interactions people have when they take Vistide and Methotrexate. It is created by eHealthMe based on reports of 18 people who take the same drugs from the FDA, and is updated regularly.
