ObjectiveTo report the consistent effect of intranasal lidocaine 4% on preventing headache following aura in one individual.BackgroundA treatment that could prevent the headache which follows an aura would be an important advance in the treatment of migraine. No migraine abortive treatment has been shown to have such an effect.MethodsA 15-year-old adolescent boy with a history of recurrent headache since aged 2, fulfilling the criteria for migraine with aura, was seen in consultation. Intranasal lidocaine 4% was used during the aura phase to prevent the headaches.ResultsBefore using intranasal lidocaine, the patient invariably experienced a migraine following a typical visual aura. The episodes occurred approximately weekly, with a stable pattern for several years. When given during the aura, intranasal lidocaine prevented the headache following the aura, and remained successful on all but two occasions over 1 1/2 years of use (approximately 75 episodes). There was no effect on the duration of the aura itself.ConclusionsIntranasal lidocaine consistently prevented the development of headache symptoms following aura in this individual. Such an effect suggests a role for the sphenopalatine ganglion in the development of migraine pain.
