Botox is only FDA-approved for chronic migraines, which means headache on 15 or more days a month.
Botox is a form of botulinum toxin, a neurotoxin produced by the bacteria that causes botulism. It is injected in multiple areas around the forehead, and back of head and neck. Botox enters the nerve endings around where it is injected and blocks the release of chemicals involved in pain transmission, which ultimately helps headaches.
Botox injections are usually given every 3 months. It might take few days to few weeks before it might start helping headaches. Sometimes it might take 2-3 round of injections before the patients can see maximum benefits.
During the injection session, botox is injected with tiny needle in multiple areas. Sometimes the injection can cause mild burning. Most patients can tolerate the injections well. Detailed side effects will be discussed by the physician during your office visit. Also consider visiting www.botoxchronicmigraine.com to watch more videos and enrolling in savings program.
