Slow-k and Flonase drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Slow-k (potassium chloride) and Flonase (fluticasone propionate). Common drug interactions include irritable bowel syndrome among females and back pain among males.

The phase IV clinical study analyzes what interactions people have when they take Slow-k and Flonase. It is created by eHealthMe based on reports of 24 people who take the same drugs from the FDA, and is updated regularly.
