1.2 Important Limitations
Almotriptan Malate tablets should only be used where a clear diagnosis of migraine has been established. If a patient has no response for the first migraine attack treated with Almotriptan Malate tablets, the diagnosis of migraine should be reconsidered before Almotriptan Malate tablets are administered to treat any subsequent attacks.
In adolescents age 12 to 17 years, efficacy of Almotriptan Malate tablets on migraine-associated symptoms (nausea, photophobia, and phonophobia) was not established. Almotriptan Malate tablets are not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine [see Contraindications (4.7)].
Safety and effectiveness of Almotriptan Malate tablets have not been established for cluster headache which is present in an older, predominantly male population.
