Ritalin and Amaryl drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Ritalin (methylphenidate hydrochloride) and Amaryl (glimepiride). Common drug interactions include somnolence among females and pneumonia among males.

The phase IV clinical study analyzes what interactions people have when they take Ritalin and Amaryl. It is created by eHealthMe based on reports of 50 people who take the same drugs from the FDA, and is updated regularly.
