It is estimated that approximately 80 percent of those who meet the definition of Chronic Migraine have not received an accurate diagnosis and, as a result, may be unaware of their treatment options. This may be due to mischaracterization of Chronic Migraine as a less severe headache disorder.

"Patients who think they may have Chronic Migraine should seek advice from a medical specialist, such as a neurologist, headache or pain physician, who is qualified to evaluate, diagnose and properly manage this condition and see if BOTOX?® treatment is right for them," said Sheena K. Aurora, M.D., Director, Swedish Headache Center, Seattle, Washington. "Effective management of the Chronic Migraine patient requires an analysis of headache type, triggers, co-morbidities and current medications to develop an appropriate treatment plan. The FDA approval of BOTOX?® offers a new, clinically evaluated and proven option to help Chronic Migraine sufferers reduce the number of hours and days they suffer from headache for up to three months per treatment."

When treating Chronic Migraine, qualified medical specialists administer 31 injections of BOTOX?® neurotoxin into seven specific head and neck sites for a total of 155U per treatment session.
