Eletriptan 40 mg and 80 mg tablets were listed on the Pharmaceutical Benefits Scheme as authority required (streamlined) on 1 October 2010 (Table 1).1,2 Eletriptan has been available overseas for several years.3 Avoid use within 48 hours of cytochrome P450 3A4 inhibitors (e.g. ketoconazole, erythromycin, protease inhibitors), as this causes increased plasma concentrations of eletriptan.4

All triptans are effective for migraine5,6 but individual response cannot be predicted.7 If the first triptan fails, try another.
