Botox is approved for chronic migraines

Botox was just approved by the FDA for the treatment of chronic migraine headaches.  This is great news to the more than 3 million chronic headache sufferers in the US (people who have more than 15 days with headaches each month).  In Dr. Mauskop’s opinion Botox is one of the most effective treatments for frequent and severe headaches and it is the first treatment approved FDA for chronic migraines. Dr. Mauskop was one of the first headache specialists to begin using this treatment more than 15 years ago. He has published several scientific articles and book chapters on the use of Botox for headaches. His most recent chapter on Botox for headaches was just published a month ago in the 97th volume of the Handbook of Neurology (Elsevier).  Dr. Mauskop has trained over 200 doctors from all across the US, Canada and Europe who traveled to the New York Headache Center to learn this technique.  Initial reports of the use of Botox for headaches were met with disbelief, while strong skepticism about the efficacy of this treatment persisted for many years. The main reason for this skepticism was the fact that migraine headaches are known to originate in the brain, while Botox affects only muscles and nerves on the outside of the skull. A large amount of research led to our current understanding of how Botox works: while the brain begins the headache process, it requires feedback from nerves and muscles on the surface of the head. By blocking activation of the nerves and muscles the feedback loop remains open and the headache does not occur. After the first few treatments some patients still develop a migraine aura or just a sensation that the headache is about to start, but it does not. After repeated treatments even the auras and this sensation stops occurring. Botox seems to be effective in 70% of patients, which is a rate significantly higher than with any preventive migraine medications, such as Topamax (topiramate), Depakote (divalproex sodium), Inderal (propranolol), or Neurontin (gabapentin). These drugs are effective in less than 50% of patients who try them. The other 50% do not respond or develop unacceptable side effects. Lack of serious side effects is another big advantage of Botox over medications. Botox can cause cosmetic side effects, such as a surprised look, droopy eyelids, or one eyebrow being higher than the other. These and other side effects become less common as the doctor who performs them becomes more experienced. Occasionally, patients develop a headache from being stuck with a needle. This is also uncommon because the needle is very thin and if done correctly, the procedure usually causes very little pain. The effect of Botox begins about 5-6 days after the injections, but the improvement continues to occur for 3 months, at which point the second treatment is given. Some patient require Botox injections at 2 month intervals. Published studies have shown that the second treatment is usually more effective than the first and the third one is better than the second. After several treatments some people improve completely (a small percentage of patients stop having all of their headaches after the first treatment). Dr. Mauskop’s experience suggests that children as young as 10 who suffer from daily headaches also respond well to Botox injections. The major drawback of Botox is its cost. However, several insurance companies have been paying for this treatment and with the FDA approval most of them will have to cover this treatment for patients with chronic (more than 15 days a month) headaches.
