Overview

When a migraine takes over, it can feel impossible to carry on - but you don’t have to suffer in silence. Sumatriptan is one of the most trusted migraine treatments worldwide, used by millions to stop attacks in their tracks. By calming the brain changes that trigger migraines and narrowing widened blood vessels, it works directly at the root of migraine pain - easing throbbing headaches, nausea, and sensitivity. With relief that often begins within the hour, Sumatriptan helps you regain control, restore comfort, and get back to what matters most.

What is Sumatriptan


Sumatriptan is part of the triptan class of medicines (5-HT1 receptor agonists) and is specifically used for the acute treatment of migraine attacks, with or without aura.

Unlike standard painkillers, Sumatriptan works directly on the migraine process itself by:

  • Narrowing widened blood vessels in the brain
  • Calming overactive nerve activity
  • Relieving migraine symptoms such as pain, nausea, and light/sound sensitivity


It is one of the most commonly prescribed triptans in the UK and has been relied on for decades as an effective first-choice treatment for migraine attacks.

Sumatriptan is not intended for preventing migraines - it should only be taken when an attack begins.

Directions

  • Take one 50mg or 100mg tablet as soon as migraine symptoms start.
  • If the migraine improves but then returns, a second dose may be taken after 2 hours.
  • Do not exceed 300mg in 24 hours.
  • Tablets should be swallowed whole with water.


Not recommended for children under 18. Always follow the instructions provided by your prescriber.

Side Effects

Like all medicines, Sumatriptan tablets can cause side effects, although not everyone gets them. Most side effects are mild and pass quickly.

Common (may affect more than 1 in 10 people):

  • Tiredness or drowsiness
  • Dizziness or feelings of weakness
  • Flushing or unusual warm sensations

 

Less common (may affect up to 1 in 100 people):

  • Tingling, numbness, or heaviness
  • Muscle aches or stiffness
  • Temporary changes in blood pressure

 

Rare but serious (seek medical advice immediately):

  • Severe chest pain, pressure or tightness
  • Signs of a severe allergic reaction: swelling of the face, lips, tongue or throat, or difficulty breathing
  • Irregular heartbeat or palpitations

 

Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet that comes with your medicine. If you notice anything unusual or concerning, stop using the medicine and seek medical advice promptly. In an emergency, call 999 or go to A&E.

Warnings

Sumatriptan may not be suitable if you:

  • Are under 18 or over 65
  • Are pregnant or breastfeeding (unless advised by your prescriber)
  • Have uncontrolled high blood pressure, heart disease, or history of stroke
  • Are taking other migraine medicines (including other triptans or ergotamine)
  • Are taking SSRIs, SNRIs, or MAOIs (antidepressants) - risk of serotonin syndrome
  • Have severe liver disease or kidney problems


Always provide your prescriber with your full medical history and a list of all medicines you take.

Frequently asked questions
  • What is sumatriptan and how does it treat migraines?

    Sumatriptan is a triptan medicine that treats migraines by narrowing widened blood vessels and calming pain pathways in the brain. It works best when taken early in an attack and can reduce pain, sickness and sensitivity to light or sound.

  • How quickly does sumatriptan work?

    Most people feel relief within 30–60 minutes when using tablets, and sometimes faster with the nasal spray. Injections work quickest, often within 10–15 minutes. Taking it at the first sign of a migraine usually leads to better results and less recurrence.

  • How do I take sumatriptan safely?

    Take one dose at the start of your migraine symptoms. Only take a second dose if advised and after the recommended time gap. Do not use it more than the allowed number of days per month, as this can lead to medication-overuse headache.

  • What side effects can sumatriptan cause?

    Common effects include warm sensations, tingling, tightness in the chest or throat, dizziness or tiredness. These feelings are usually short-lived. Rare symptoms like severe chest pain or breathlessness need urgent medical attention. Always speak to a clinician if side effects persist.

  • Who should not take sumatriptan?

    Sumatriptan is unsuitable for people with heart disease, a history of stroke, uncontrolled high blood pressure, vascular disease or certain rhythm problems. It also interacts with some antidepressants. A clinician will check if it’s safe for you.

  • Can I take a second dose of sumatriptan if my migraine comes back?

    Yes, if clinically appropriate. You can usually take a second dose after the advised interval, but not within the same hour. Do not exceed the daily maximum. If your migraine returns every time, preventive treatment may be needed.

  • Is sumatriptan effective for severe or fast-building migraines?

    Yes. Sumatriptan can be very effective for sudden or intense migraines when taken early. Some people find nasal spray or injection forms work better during severe attacks or when nausea delays absorption of tablets.

  • Why do some people feel pressure, flushing or tingling after taking sumatriptan?

    These sensations are common and linked to how the medicine affects blood vessels and nerve pathways. They usually improve within 30 minutes and are not dangerous for most people. If symptoms feel severe or frightening, speak to a clinician to review suitability.

  • Does sumatriptan work for migraines that start on waking?

    Yes. Many people wake with migraines triggered by sleep changes, grinding teeth or hormonal shifts. Sumatriptan can still help if taken as soon as symptoms begin. Faster forms like nasal spray may be especially useful during morning attacks.

  • Can sumatriptan help with menstrual or hormone-related migraines?

    Yes. Sumatriptan is often effective for menstrual migraines, which can be more intense and harder to manage. Taking it early can improve results. If attacks occur predictably, a clinician may recommend a specific treatment plan around your cycle.

  • Can I take sumatriptan if I am already using painkillers or anti-sickness medicine?

    Yes, many people safely combine sumatriptan with paracetamol, ibuprofen or anti-sickness tablets like metoclopramide. Avoid codeine or opioid painkillers because they increase the risk of medication-overuse headaches. Always check your current medicines first.

  • Does sumatriptan work differently in tablet, nasal spray or injection form?

    The active ingredient is the same, but speed varies. Injections work fastest, nasal spray is helpful when nausea is strong, and tablets suit most people. Choice depends on how quickly your migraines escalate and whether you struggle with sickness.

  • Is sumatriptan suitable for people with cluster headaches?

    Sumatriptan injections are an effective treatment for cluster headaches and are often prescribed for this condition. Tablets are less helpful because cluster attacks come on very quickly. Always follow specialist advice.

  • Why might sumatriptan stop working for me over time?

    Migraine patterns can change due to hormones, stress, sleep disruption or medication overuse. If sumatriptan becomes less reliable, another triptan or preventative therapy may be more suitable. Reviewing triggers can also help.

  • What should I do if sumatriptan helps but the migraine quickly returns?

    A second dose may help if taken within the safe interval. If headaches repeatedly return, another triptan or a longer-acting option might work better. Keeping a diary can show patterns that guide treatment.
