Dihydroergotamine

Dihydroergotamine (DHE) is a medication used to treat migraines. It works by narrowing blood vessels in the brain, which helps reduce headache pain and other migraine symptoms like nausea and sensitivity to light or sound. DHE is typically given as an injection or nasal spray and is usually used when other medicines haven't worked. It is important to use DHE under medical supervision because it can have side effects like dizziness or nausea and may not be suitable for people with certain health conditions.
