How to get Sumatriptan Over The Counter

When a migraine happens,  many patients reach for common analgesics such as paracetamol and ibuprofen, or combination products containing codeine such as co-codamol or Migraleve. Sumatriptan is a medication that can be used to relieve an acute migraine attack. Sumatriptan works differently to analgesics. In this post, I will discuss the mechanism of action, suitability & requirements for the supply and possible side effects of sumatriptan over the counter.

Sumatriptan mechanism of action?

As the name suggests sumatriptan belongs to a group of drugs called ‘triptans’. Sumatriptan acts on serotonin receptors located in the brain. The main mechanism of action of triptans is constriction (narrowing) of the blood vessels in the brain to counteract dilation which causes the migraine headache. Other mechanisms of triptans are known, however, the description of these is beyond the scope of this post.

Triptans have a fast onset of action and target the areas involved in migraines development with great precision (affinity) allowing good effectiveness in symptom relief, with a low occurrence of side effects (Tepper et al, 2002).

What brand of sumatriptan over the counter can be purchased from the pharmacy?

The following brands of sumatriptan are available in the UK:

  • Migraitan 50mg tablets
  • Imigran Recovery 50mg tablets
  • Boots Migraine Relief 50 mg Tablets

All of the above products are pharmacy only medicines, sold under the supervision of a pharmacist. Each product contains two sumatriptan 50mg tables.

Sumatriptan over the counter requirements

Sumatriptan over the counter is licensed for adults aged 18-65 in treatment of acute symptoms of migraines. Sumatriptan is not taken to prevent a migraine attack. Patients requesting a supply of sumatriptan from the pharmacy are usually asked to complete a health questionnaire to help to confirm that:

  • Age is appropriate
  • The patient is not pregnant or breastfeeding
  • The patient had more than 4 migraine attacks in the past and the first one happened more than a year ago
  • The patient was diagnosed with migraines by a doctor and had been previously prescribed triptans or other prophylactic medication
  • Diagnosis by a doctor is not required, patients can answer further questions to help pharmacist to confirm a migraine diagnosis

Additionally, patients are asked about:

  • frequency, the duration, and symptoms they experience during a migraine attack
  • medication being taken

Lastly, the patient requesting sumatriptan over the counter will need to answer questions to assess cardiovascular risk:

  • Weight & BMI
  • Family history of heart disease
  • Any medical conditions increasing cardiovascular risk such as diabetes or high cholesterol

Sumatriptan should only be used where a clear diagnosis of migraines has been made by a doctor or pharmacist.
