Headache.

Headache-prone patients have many highly effective therapeutic options open to them. Used only at the time of headache, sumatriptan succinate by mouth or injection and dihydroergotamine nasal spray are novel choices now or soon to be available. The original migraine therapy, ergotamine, is highly effective in its rectal suppository formulation, when used at a subnauseating dosage. Valproate sodium is the latest addition to the many therapies available for long-term stabilization.
