Dihydroergotamine is a medication primarily used to treat acute migraine attacks and cluster headaches. It works by constricting blood vessels in the brain, which helps alleviate headache symptoms. Dihydroergotamine can be administered through injection or nasal spray, providing options for patients based on their preferences and needs. This drug belongs to a class of medications known as ergot alkaloids, derived from the ergot fungus. While effective for many, it may cause side effects such as nausea, dizziness, or tingling sensations. Patients should consult their healthcare provider to determine if dihydroergotamine is suitable for their condition.
