What Metomax is used for
Metomax is used to treat nausea experienced with migraine headaches.
Migraine is a condition that is thought to be caused by the widening of certain blood vessels in the brain causing a recurrent headache that normally affects one side of the head.
Migraines are usually described as intense, throbbing or pounding pain that involves the temple, but can sometimes be located in the forehead, around the eye or the back of the head.
There are many symptoms that may accompany migraines; nausea (feeling sick) is one of the most common.
Metomax contains paracetamol and metoclopramide (as hydrochloride).
Paracetamol is an analgesic, used for temporary relief from pain (such as headache). Metoclopramide is an anti-emetic, used to control nausea and vomiting caused by migraine.
Ask your doctor or pharmacist if you have any questions about why Metomax has been recommended for you.
Your doctor or pharmacist may have recommended Metomax for another reason.
This medicine is not addictive.
Metomax is a "Pharmacist Only Medicine". It is available without a doctor's prescription but your pharmacist's advice is required.
