What Paramax contains

Paramax contains two different medicines. These are called:

  • Metoclopramide hydrochloride: this belongs to a group of medicines called anti-emetics. It works on muscles in the upper part of the digestive system causing your stomach to empty. It also works on a part of your brain that prevents you from feeling sick (nausea) or being sick (vomiting)
  • Paracetamol: This belongs to a group of medicines called painkillers (analgesics). It works by stopping substances that naturally occur in your body called prostaglandins from being made. Prostaglandins cause pain. If they are blocked, pain is relieved
