Acute migraine (Formulary)

TAM (Treatments and Medicines) NHS Highland

Soluble simple analgesics (eg paracetamol 1g for mild to moderate migraine, or for all severities of migraine ibuprofen 400mg or soluble aspirin 900mg), if necessary, with an antiemetic, eg metoclopramide 10mg (Drugs used in nausea and vertigo), are often effective if taken early in the attack. Diclofenac or paracetamol suppositories may be an option.

Reserve triptans for patients resistant to simple analgesics and antiemetic therapy; if the headache always progresses to a moderate to severe attack despite patients taking acute therapy when symptoms are still mild, then consider triptans.

Use during the established headache phase and not during the aura phase of an attack.

In triptan responders, approximately one in four attacks do not respond to triptans. Refer to SIGN 155: Pharmacological management of migraine and NICE CG150: Headaches in over 12s: diagnosis and management.

Continue triptan treatment for 3 months and only discontinue at that point if ineffective. If one triptan is ineffective then consider trial of another.

  • Triptans should not be used in ischaemic heart disease or coronary vasospasm (including Prinzmetal’s angina), uncontrolled hypertension and previous myocardial infarction (refer to BNF), or with ergotamine.
  • Advise patients that triptans should be taken on no more than 2 days per week due to the risk of developing medication overuse headache.

Other triptans, eg naratriptan, almotriptan and frovatriptan, may be considered for the treatment of non-responsive episodic migraine; refer to BNF.

 Advise all patients starting on any acute headache treatment:
  • of the risk of developing medication-overuse headache
  • to take any acute headache treatment on no more than 2 days per week
  • to avoid opioids (including codeine and dihydrocodeine).
