Reglan and Unasyn drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Reglan (metoclopramide hydrochloride) and Unasyn (ampicillin sodium; sulbactam sodium). Common drug interactions include pleural effusion among females and anaemia among males.

The phase IV clinical study analyzes what interactions people have when they take Reglan and Unasyn. It is created by eHealthMe based on reports of 74 people who take the same drugs from the FDA, and is updated regularly.
