Septra and Ketoconazole drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Septra (sulfamethoxazole; trimethoprim) and Ketoconazole (ketoconazole). Common drug interactions include haemoptysis among females and anaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Septra and Ketoconazole. It is created by eHealthMe based on reports of 69 people who take the same drugs from the FDA, and is updated regularly.
