Potassium iodide and Bactrim drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Potassium iodide (potassium iodide) and Bactrim (sulfamethoxazole; trimethoprim). Common drug interactions include eye swelling among females and asthenia among males.

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