Headache, rebound

Headache, rebound: Headaches experienced by those who have taken ergotamine or analgesic medications for migraines or other health conditions, and who have built up a tolerance for these medications. Often the headache occurs right after the medication wears off. Treatment is by using the medication less frequently, or switching to a different pain reliever. Some patients with acute ergotamide rebound headaches find relief with injected phenothiazine or long-acting steroid medication.
