What is Sumatriptan?

Sumatriptan is a medicine used for the acute treatment of migraine attacks. It works once a migraine has started and helps relieve symptoms during an attack.

Sumatriptan belongs to a group of medicines called triptans. These medicines work by stimulating serotonin (5-HT₁) receptors in the brain. This helps to narrow widened blood vessels and reduce pain signals linked to migraine attacks.

Sumatriptan may help relieve:

  • Migraine with or without aura
  • Moderate to severe migraine headache pain

It can also help reduce associated symptoms such as:

  • Nausea or vomiting
  • Sensitivity to light (photophobia)
  • Sensitivity to sound (phonophobia)

Sumatriptan works best when taken as soon as migraine symptoms begin. It is not used to prevent migraines.

Who is Sumatriptan suitable for?

Sumatriptan may be suitable for:

  • Adults aged 18–65 years who have been diagnosed with migraine

A prescriber will review your medical information to make sure this medicine is suitable and safe for you.

Sumatriptan may not be suitable for people who:

  • Have certain heart or circulation conditions
  • Have uncontrolled high blood pressure
  • Have had a stroke or transient ischaemic attack (TIA)
  • Are taking medicines that interact with triptans

Always provide accurate information about your medical history and medicines when ordering online.

How to take Sumatriptan

Always take sumatriptan exactly as prescribed by your prescriber or pharmacist.

Typical dose for adults (18–65 years)

  • Take one tablet as soon as your migraine starts
  • Swallow the tablet whole with water
  • It can be taken with or without food

If your migraine improves but then returns, you may take a second tablet after at least 2 hours.

Important advice:

  • Do not take more than 300 mg in 24 hours
  • Do not take another dose for the same attack if the first tablet does not work
  • Do not crush or chew the tablet
  • Do not use sumatriptan to prevent migraines

If your migraines become more frequent or the medicine does not help, speak to a healthcare professional.

Sumatriptan is taken only when needed for a migraine attack, so there is no regular daily dose to miss.

Take it when migraine symptoms begin.

Do not exceed the prescribed dose.

If you take more than recommended, seek medical advice. You can contact NHS 111 for urgent advice or 999 in an emergency.
