Acute treatments
Sumatriptan
- Tablet 50mg, 100mg (£0.20 = per 100mg tablet)
- Solution for injection 6mg/0.5ml syringe (£48.19 = pack 2 generic pre-filled syringes)
- Solution for injection 3mg/0.5ml syringe (£39.50 = pack 2 pre-filled syringes) (see note 2 below)
- Nasal spray 10mg/0.1ml actuation, 20mg/0.1ml actuation (£42.47 = 20mg pack 6 unit doses)
Indications
Dose
- Oral: migraine. Dose: 50mg (some patients may require 100mg); the dose may be repeated after at least 2 hours if migraine recurs; maximum 300mg in 24 hours
- Subcutaneous 6mg injection: cluster headache or migraine. Dose: a single 6mg injection; the dose may be repeated once after at least 1 hour if headache recurs; maximum 12mg in 24 hours
- Subcutaneous 3mg injection: migraine if sumatriptan 6mg injection is effective, but not tolerated. Dose: a single 3mg injection; the dose may be repeated once after at least 1 hour if headache recurs; maximum 6mg in 24 hours (see note 2 below)
- Intranasally: cluster headache [unlicensed] or migraine. Dose: 10–20mg into one nostril; the dose may be repeated once after at least 2 hours if headache recurs. Maximum in 24 hours: two 10mg doses or two 20mg doses
Notes
- Sumatriptan nasal spray is licensed for use in children aged 12 to 18 years of age
- Sumatriptan 3mg subcutaneous injection is included in the formulary for the treatment of migraine only. There is very limited evidence comparing sumatriptan 3mg and 6mg subcutaneous injection. If sumatriptan 6mg subcutaneous injection is effective but not tolerated, consider reducing the dose to the 3mg injection. If a patient consistently uses more doses of sumatriptan 3mg injection than the 6mg injection, prescribing of the 3mg injection should be reconsidered.
- All prescriptions for sumatriptan should be written generically.
Almotriptan
- Tablet 12.5mg (£2.79 = per tablet)
Indications
Dose
- 12.5mg as soon as possible after onset repeated after 2 hours if migraine recurs (patient not responding should not take second dose for same attack); maximum 25mg in 24 hours
Frovatriptan
- Tablet 2.5mg (£3.34 = per tablet)
Indications
Dose
- 2.5mg as soon as possible after onset repeated after 2 hours if migraine recurs (patient not responding should not take second dose for same attack); maximum 5mg in 24 hours
Notes
- Frovatriptan has been included because it has a much longer half-life than other agents and the effects may last for longer.
Rimegepant
- Oral lyophilisate sugar free 75mg (£25.80 = pack of 2; £103.20 = pack of 8)
Indications and dose:
- Acute treatment of migraine in line with NICE TA919 (see note 9)
- 75mg once daily if required. Maximum dose 75mg/day (see note 1)
- Prophylaxis of episodic migraine in line with NICE TA906 (specialist input) (see notes 2 and 8)
- Hepatic impairment: No dose adjustment in mild or moderate hepatic impairment. Avoid in severe hepatic impairment.
- Renal impairment: No dose adjustment in mild, moderate or severe renal impairment. Caution during frequent use in severe renal impairment. Avoid in end-stage renal impairment (CrCL< 15ml/min).
Notes
- Maximum daily dose is one 75mg lyophilisate. Rimegepant is licensed for both acute treatment and prophylaxis of migraine (see above). Patients should not take an additional 75mg lyophilisate for acute treatment of migraine on the same day as receiving rimegepant for prophylaxis of migraine.
- For prophylaxis of migraine:
- Treatment with rimegepant may be started in primary care on the advice of a specialist.
- In addition, initiation of rimegepant by GPs who are confident to do this without specialist input is accepted. Refer to guidance on the prophylaxis of migraine for patient groups requiring specialist input and additional information on treatment review.
- Interactions: Rimegepant is metabolised by CYP3A4. Concomitant administration with strong CYP3A4 inhibitors, or moderate or strong CYP3A4 inducers is not recommended. Rimegepant is also associated with additional drug interactions. Refer to the BNF or rimegepant SmPC for advice on drug interactions.
- Cardiovascular disease: Clinicians should be aware that the following patients were excluded from the phase 3 trials of rimegepant:
- Current evidence of uncontrolled, unstable or recently diagnosed cardiovascular disease, such as ischaemic heart disease, coronary artery vasospasm, and cerebral ischaemia.
- Patients with myocardial infarction, acute coronary syndrome, percutaneous coronary intervention, cardiac surgery, stroke or TIA during the 6 months prior to being enrolled in the trial.
- Uncontrolled hypertension. Patients with stable hypertension 3 months prior to being enrolled were eligible to participate in the trial.
- History or current evidence of arrhythmia and some ECG changes (e.g. left bundle branch block)
- Pregnancy and breastfeeding: There are limited data from the use of rimegepant in pregnant women and in breastfeeding. Refer to the rimegepant SmPC for further information.
- The lyophilisate should be placed on the tongue or under the tongue. It can be taken without liquid.
- The annual cost per patient for prophylaxis of migraine is £2,368.
- NICE TA906: Rimegepant is recommended as an option for preventing episodic migraine in adults who have at least 4 and fewer than 15 migraine attacks per month (July 2023), only if at least 3 preventative treatments have not worked:
- Stop rimegepant after 12 weeks of treatment if the frequency of migraine attacks does not reduce by at least 50%.
- If people with the condition and their clinicians consider rimegepant to be 1 of a range of suitable treatments, after discussing the advantages and disadvantages of all the options, use the least expensive. Take account of administration costs, dosage, price per dose and commercial arrangements.
- NICE TA919: Rimegepant is recommended as an option for the acute treatment of migraine with or without aura in adults (Oct 2023), only if for previous migraines:
- at least 2 triptans were tried and they did not work well enough or
- triptans were contraindicated or not tolerated, and non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol were tried but did not work well enough.
Prophylaxis of migraine
Drugs used for prophylaxis of migraine not listed below:
Atogepant

- Interactions: Atogepant is metabolised by CYP3A4 and eliminated via the OATP pathway. Reduce daily dose of atogepant to 10mg once daily with concomitant administration of a strong CYP3A4 or OATP inhibitors. Refer to the BNF or atogepant SmPC for advice on drug interactions.
- Cardiovascular disease: Clinicians should be aware that the following patients were excluded from the phase 3 trials of atogepant:

- The annual cost per patient for prophylaxis of migraine is £2,368.
- NICE TA973 (May 2024): Atogepant is recommended as an option for preventing migraine in adults who have at least 4 migraine days per month, only if at least 3 preventive medicines have failed
