Sumatriptan 100mg tablets are available to order online from The Independent Pharmacy Online Doctor. Sumatriptan tablets contain the active ingredient Sumatriptan, a generic version of Imigran, which cause expanded blood vessels in the brain to contract and thereby helping to relieve migraines. 

Sumtriptan (generic Imigran) causes the blood vessels in the brain to contract. As some of the changes that occur in the brain to trigger a migraine attack are believed to involve the blood vessels widening, triptans (such as Sumatriptan) help to reverse this process and relieve the symptoms of migraine. They may also have some effect by stabilising some of the chemical changes that occur in the brain during a migraine attack. Sumatriptan (Imigran) usually starts to work after 30 minutes, therefore it important to take it as soon as possible into a migraine attack. Sumatriptan may not work for everyone, where it does not work alternative 'triptans', such as almotriptan (Almogran) and favotriptan (Migard) are worth trying.

Sumtriptan is the drug contained in the branded Imigran tablets. Imigran Recovery tablets are available to buy in the pharmacy and contain sumatriptan 50mg, whereas The Independent Pharmacy Online Doctor is able to prescribe generic Sumatriptan 100mg, a stronger prescription-only migraine treatment for more severe migraines.

Sumtriptan tablets should be taken as soon as possible after the onset of a migraine to help reduce symptoms as soon as possible. You can repeat the dose of 100mg after 2 hours if your migraine has not been relieved.

Sumatriptan 100mg tablets can be taken with painkillers such as paracetamol, ibuprofen or codeine or with antisickness medicines such as Buccastem, to help treat any additional symptoms associated with your migraines.You should not take any other migraine treatments containing 'triptans' whilst you are taking Sumatriptan.

Take 100mg (ONE tablet) at onset of symptoms, dose may be repeated after at least 2 hours if migraine symptoms return. Maximum dose is 300mg in 24 hours (three 100mg tablets).

Sumatriptan (Imigran) usually starts to work after 30 minutes. It does not work for everyone. Where it does not work alternative 'triptans' are worth trying.

Sumatriptan should not be taken with other 'triptans' or with medication containing ergotamine.

Each sumatriptan tablet contains sumatriptan succinate 140mg (equivalent to 100mg sumatriptan) as the active ingredient.

Each tablet also contains: lactose monohydrate, hypromellose, microcrystalline cellulose, crosscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide (E171), triacetin, red iron oxide (E172).

The side effects of sumatriptan can include pain, heaviness, pressure or tightness in the chest, throat or other parts of the body, or unusual sensations, including numbness, tingling and warmth or cold. These effects may be intense but generally pass quickly. Please read the Patient Information Leaflet enclosed with your medicines for a full list of side effects.

Other common side effects include:

  • Feeling sick (nausea) or being sick (vomiting), although this may be due to the migraine itself
  • Tiredness or drowsiness
  • Dizziness, feeling weak, or getting hot flushes
  • Temporary increase in blood pressure
  • Shortness of breath
If you feel pain or tightness in your chest after you use sumatriptan, do not panic, the symptoms may be intense but they usually pass quickly. If they do not pass quickly or they become severe, get medical help immediately. 

If you find that your medicine is effective but you get mild unwanted side effects, you may wish to lower the strength of your treatment to Sumatriptan 50mg tablets to see if they are still effective without the side effects. 


Sumatriptan has been widely used for many years and is generally considered a safe drug.

Sumatriptan (Imigran) can cause a temporary narrowing of blood vessels. People who have had strokes or mini-strokes, have problems with poor circulation, or a history of angina (heart pain on exertion) or a have had heart attacks should not take sumatriptan.

Even in people who have never had circulation problems sumatriptan can in rare situations trigger serious heart problems. The following groups should check with their GP before taking sumatriptan:

  • Heavy smokers
  • Men over 40
  • Women after the menopause

In some rare serious cases migraine headaches are associated with paralysis, loss of vision and loss of speech. Sumatriptan is not to be used in these cases.

  • Before self medicating for headaches it is best to see a GP for a diagnosis
  • When headaches start for the first time over the age of 40
  • When headaches are getting more frequent and lasting longer
  • When headaches are different from before or there are new symptoms

You should not use sumatriptan tablets if:

  • You are allergic to sumatriptan or any of the ingredients
  • You have high blood pressure
  • You have severely reduced liver function
  • You use, or have recently used, ergotamine or similar medicines (e.g. methsergide maleate) or MAO inhibitors (e.g. moclobemide or selegiline).
