Personal communication
Badminton M (2006): Almotriptan has been used without any adverses effects in a 17 yr old female with VP (no previous attacks).
IPNet drug reports
One report of a possible beginning of an acute porphyric attack in a susceptible female with AIP, but the attack was poorly documented and several other factors could explain the symptoms. This report has therefore not been taken into account in the judgement of the porphyrinogenicity of almotriptan. Uneventful use reported in 1 patients with acute porphyria.
