What is Imigran?

Imigran tablets are a migraine treatment containing the active ingredient sumatriptan. This medicine is specifically designed to reverse the cause of a migraine headache rather than just treating migraine symptoms like painkillers or nausea medicines.

Imigran is made to be taken as soon as you start to feel a migraine coming on, sometimes alleviating migraine symptoms before they become severe. Typically Imigran is only prescribed by doctors if painkillers alone are not effective enough or if your migraines are particularly severe.

Migraines must be diagnosed by a medical professional before using Imigran as it will not benefit non-migraine headaches.


A migraine is characterised by moderate to severe throbbing headache on one side of the head, it sometimes follows visual symptoms known as aura, the cause of migraines is a temporary widening of blood vessels in the brain. Other symptoms of a migraine attack are nausea, vomiting, increased sensitivity to light and sound. Symptoms of an aura are generally seeing bright lights, flashing lights, zigzag patterns which usually dwindle prior to a headache settling in.

If you have migraines on 5 or more days a month or migraines are affecting your quality of life but have not previously been diagnosed by a medical professional talk to your GP about them.

Migraines are usually triggered by certain events. Each person should note their triggers and do their best to avoid them. More information about common triggers can be found on our migraine page.

How does Imigran work?

A widening of the blood vessels in the brain is strongly suspected to be the cause of migraines. Triptans like Imigran (sumatriptan) stimulate the muscles on the widened blood vessels causing them to contract and return to their normal size, relieving or reducing the severity of the migraine.

Imigran and Sumatriptan tablets

Imigran is the brand name version of sumatriptan. There is no difference in the strength and effectiveness of the tablets, only the price and the manufacturer. GSK was the first company to create sumatriptan tablets as Imigran worldwide.

The sumatriptan patent expired allowing more companies to make the medicine. Sumatriptan is available at a significantly reduced cost as other companies have made their version of the medicine and had them tested to prove they are as effective as the original.

How to take Imigran

Swallow whole ONE tablet with water at the first sign of a migraine attack. If your symptoms begin to resolve but return after 2 hours, you may take another dose. Do not take a second tablet for the same attack if the first has no effect. A maximum of 300mg of Imigran may be used within 24 hours.

Alternative treatments

There are many alternatives to Imigran for migraine relief. Most come from the same family of medicines, triptans. Although similar, some people may respond better to one triptan than another. If you find your triptan is not providing enough migraine relief, consult your doctor or pharmacist for advice.

Some alternative treatments include Maxalt wafers, Rizatriptan and Zolmitriptan. If you would prefer an alternative form of Imigran, sumatriptan is the significantly better priced generic version. Imigran also comes in a nasal spray if you would prefer to not take a tablet.

Side Effects

Imigran side effects

As with all medicines, Imigran can have the potential to cause some side effects, although not everyone will experience them. Side effects can vary in how common they are and their severity. If you experience a side effect that bothers you or is severe, consult your doctor.

Common side effects that can occur in 1-10% of people are:

  • Drowsiness
  • Dizziness
  • Facial flushing
  • A tingling sensation
  • Nausea (may be due to the migraine itself)
  • Temporary increase in blood pressure

Using Imigran too frequently may cause medication overuse headaches. If you require triptan medicines often, speak to your doctor about preventative therapy and your options.

For a full list of potential side effects from Imigran, read the patient information leaflet.

Before using any treatment, it is recommended to read the patient information leaflet.

Other Medicines and Imigran tablets

Some medicines may interact with Imigran. It is important that you provide this information to the doctor before use.

In particular antidepressants in the MAOI class (monoamine oxidase inhibitors) can interact with this medicine. If you have taken an MAOI in the last 2 weeks, inform your doctor. Other antidepressants such as SSRIs and SNRIs and some herbal antidepressants such as St Johns Wort can also interact.

Imigran in pregnancy and breastfeeding

There is little clinical evidence of the safety of Imigran in pregnancy. Due to this, it is generally not recommended to use during pregnancy unless under direct instruction by a doctor.

When breastfeeding while taking Imigran it is important to not breastfeed the baby within 12 hours after an Imigran dose. The medicine does pass into the breast milk and to the baby if breastfed. Continue to express breast milk during this time and discard it.
