Summary:

Drug interactions are reported among people who take Pentam (pentamidine isethionate) and Vistide (cidofovir). Common drug interactions include aplastic anaemia among females and acute respiratory distress syndrome among males.

The phase IV clinical study analyzes what interactions people have when they take Pentam and Vistide. It is created by eHealthMe based on reports of 13 people who take the same drugs from the FDA, and is updated regularly.
