1. What MigraMax is and what it is used for

The name of your medicine is MigraMax 900mg/10mg Powder for oral solution (called MigraMax in this leaflet).

What MigraMax contains

MigraMax 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).
  • DL-lysine acetylsalicylate: This belongs to a group of medicines called painkillers (analgesics). DL-lysine acetylsalicylate is broken down in your body to aspirin (acetylsalicylic acid). This works by blocking a substance that naturally occurs in your body called cyclo-oxygenase. Cyclo-oxygenase makes some of the chemicals that cause pain. If it is blocked, pain is relieved.

What MigraMax is used for

MigraMax is used to treat the signs of migraine, such as headache, feeling sick (nausea) or being sick (vomiting) in adults 18 years and over.
