Donna Hill Howes, RN

Botulinum toxin A (Botox) injections are used to prevent migraine headaches. Botulinum toxin A is FDA-approved for people who have 15 or more migraine headaches a month. It may reduce the number of migraines by 2 a month. It is usually reserved for people who have not had success with other migraine treatments.
