Nasal sumatriptan: new dosage. For adolescents with migraine: too little benefit.

(1) The reference first-line drug therapy for migraine attacks in adolescents is a non specific analgesic such as paracetamol or a nonsteroidal antiinflammatory drug like ibuprofen. Two specific analgesics are authorised for use in this setting in France, namely ergotamine and dihydroergotamine. (2) Nasal sumatriptan is the first triptan to be licensed for this age group in France. (3) Evaluation data includes three flawed placebo-controlled trials. (4) Effects were modest at best. Only one of the three trials showed that sumatriptan was more likely than placebo to give complete pain relief within two hours. The three trials fail to show that sumatriptan is effective against symptoms such as nausea and vomiting, photophobia and phonophobia. (5) The principal known adverse effects of sumatriptan are chest tightness, flushing, and increased blood pressure. (6) In the only trial report containing relevant information, unpleasant taste was the only adverse effect more commonly associated with sumatriptan than with placebo. (7) Postmarketing follow-up revealed a number of serious adverse effects, including stroke, myocardial infarction and loss of vision. (8) The packs containing 6 or 12 spray vials carry a risk of overuse and self-induced headache. (9) In practice, sumatriptan must not be used to treat migraine attacks in adolescents.
