Botox has been approved for treating headaches that are present more than 15 days per month. It is used to prevent headaches in adults with chronic migraine who have 15 or more days each month with headache lasting 4 or more hours each day in people 18 years or older.In the quest to find relief from chronic migraine headaches, patients will try just about anything. After all, migraines are painful, debilitating headaches. People with chronic migraines experience these severe headaches 15 or more days each month. Quality of life is greatly affected by this disorder. Treatment is the only chance for relief.
Chronic migraine treatment can help ease symptoms, but not all patients respond well to pain medicines. In some cases, doctors prescribe preventive medicines. These are designed to reduce the frequency and severity of headaches. According to a study in the journal Neurology, about one-third of patients with chronic migraines take preventive medicines.
Earlier this decade, onabotulinumtoxinA (more commonly known as Botox-A or Botox) gained U.S. Food and Drug Administration (FDA) approval as a migraine treatment. It is now widely used as a chronic migraine treatment.
