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 which is an antiemetic and 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.

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

2. What you need to know before you take MigraMax

Do not take this medicine and tell your doctor if you:

  • are allergic to:
    • Metoclopramide hydrochloride
    • DL-lysine acetylsalicylate (aspirin)
    • Other salicylates or non-steroidal anti-inflammatory medicines (NSAIDs)
    • Any of the other ingredients of MigraMax (listed in section 6)

Signs of an allergic reaction can include a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue

  • have bleeding, obstruction or a tear in your stomach or gut

  • are taking levodopa (a medicine for Parkinson’s disease) or dopaminergic agonists (see below “Other medicines and MigraMax”)
  • have ever had abnormal blood pigment levels (methaemoglobinemia) or NADH cytochrome-b5 deficiency
  • have a condition called mastocytosis as the use of aspirin may cause severe allergic reactions such as skin flushing, low blood pressure, a fast heartbeat and vomiting
  • are under the age of 18
  • have haemophilia or any other blood clotting or bleeding problems
