Headaches related to triptans therapy in patients of migrainous vertigo.

Dizziness and vertigo are frequently reported by patients with migraine. In migrainous vertigo (MV), vertigo is causally related to migraine. Patients of MV usually have an attenuated or absent headache with their vertigo as compared with their usual headache of migraine. Here we report three female patients of MV in which administration of triptan was associated with induction (two patients) or exacerbation (one patient) of headache with disappearance of vertigo. We suggest that headache and vertigo of migraine may be inversely related to each other and suppression of one may induce or aggravate the other.
