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

Summary:

Drug interactions are reported among people who take Slow-k (potassium chloride) and Prilosec (omeprazole). Common drug interactions include palpitations among females and cardiac failure congestive among males.

The phase IV clinical study analyzes what interactions people have when they take Slow-k and Prilosec. It is created by eHealthMe based on reports of 45 people who take the same drugs from the FDA, and is updated regularly.
