Preventative migraine therapy is taken regularly to help reduce the frequency, severity, and duration of headaches. Acute therapy is taken to relieve symptoms after a migraine or headache starts.

Medication overuse headache is a type of headache caused by taking acute headache medications – including over-the-counter pain relievers and prescription medications – too often.

To help prevent medication overuse headaches:
