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

Summary:

Drug interactions are reported among people who take Potassium (potassium) and Methylphenidate (methylphenidate). Common drug interactions include cataplexy among females and tachycardia among males.

The phase IV clinical study analyzes what interactions people have when they take Potassium and Methylphenidate. It is created by eHealthMe based on reports of 79 people who take the same drugs from the FDA, and is updated regularly.
