It appears as if you have been prescribed sumatriptan to treat your headaches. It is not uncommon for patients taking sumatriptan to experience “rebound headaches” when the drug’s effects wear off. This is especially true if a person is taking sumatriptan more than two times per week. Rebound headaches often become a progressive syndrome as the patient starts taking more medication to decrease headaches resulting in a vicious cycle.
The proper treatment is to either taper or discontinue the offending medication. You should consult the physician prescribing your sumatriptan or a headache specialist to determine the best regimen to cure your rebound headaches.
