Amoxicillin and Whey drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Amoxicillin (amoxicillin) and Whey (whey protein). Common drug interactions include arthralgia among females and melaena among males.

The phase IV clinical study analyzes what interactions people have when they take Amoxicillin and Whey. It is created by eHealthMe based on reports of 13 people who take the same drugs from the FDA, and is updated regularly.

What is Amoxicillin?

Amoxicillin has active ingredients of amoxicillin. It is often used in infection. eHealthMe is studying from 99,235 Amoxicillin users. Check the latest studies of Amoxicillin.

What is Whey?

Whey has active ingredients of whey protein. It is often used in weight loss. eHealthMe is studying from 379 Whey users. Check the latest studies of Whey.
