Chronic daily headache is defined as the presence of a headache on 15 days or more per month for at least three months. The most common types of chronic daily headache are chronic migraines and chronic tension-type headaches. If a red flag for a secondary cause of headache is present, magnetic resonance imaging of the head should be performed. ⋯ Several prophylactic treatments for chronic daily headache can reduce headache frequency and severity, as well as improve overall quality of life. Nonpharmacologic treatments include relaxation techniques, cognitive behavior therapy, acupuncture, osteopathic manipulation, and cervical exercises. Pharmacologic therapies include amitriptyline, gabapentin, onabotulinumtoxinA, propranolol, tizanidine, topiramate, and valproate.
