What is Imigran (Sumatriptan)?

Imigran is the brand name for a medicine called sumatriptan, which belongs to a group of medicines known as triptans. Triptans are specifically used as treatments for migraines, providing fast and effective relief from migraine headaches.

It is part of a group of medicines called triptans, or serotonin (5-HT1) agonists.

Imigran tablets can be taken by adults over 18 years of age.

This medicine is also available as Imigran Nasal Spray for migraines.

What is Imigran used to treat?

Imigran (sumatriptan) is commonly prescribed to treat migraine headaches, which are often painful and debilitating, preventing you from going about your daily life.

While it is not a painkiller, you can take sumatriptan if other painkillers or nonsteroidal anti-inflammatory drugs (NSAIDs) have not provided effective pain relief.

Ideally, you should take Imigran as soon as possible after you feel a migraine coming on. Although it will still be effective if taken later on during a migraine.

How does Imigran work?

It is not completely understood what causes a migraine attack, but they are believed to be caused by the temporary widening of blood vessels in the brain.

Imigran’s active ingredient, sumatriptan, is believed to work by narrowing the blood vessels back to their normal size. This relieves the pain and other symptoms like feeling sick and being extra-sensitive to light and sound.

Sumatriptan will generally get to work after around 30 minutes of being taken.

Imigran is not a preventative medicine and should not be used to prevent migraines from occurring. It should only be taken at the onset of an attack.

How to take Imigran

For best results, take one Imigran tablet as soon as you start to feel a migraine attack coming on.

Swallow the tablet whole with a glass of water. Do not crush or chew it.

A second dose can be taken if the initial dose is not effective, or if your symptoms return. However, you must wait at least two hours before taking a second tablet.

The maximum dose is 300mg in 24 hours.

Refer to the patient information leaflet, which will come with your medicine, for full instructions. Speak to your doctor or pharmacist if you are not sure.
