FDA approves Botox to treat chronic migraines

The Food and Drug Administration recently approved Allergan Inc's anti-wrinkle injection Botox to treat chronic migraines.
Botox injections would be given to adult sufferers of chronic migraines around the head and neck every 12 weeks in an attempt to dull future headaches, said the FDA in a statement.
Chronic migraine sufferers have a headache on most days of the month. Botox has not been shown to work for people who suffer headaches 14 days or less per month, the FDA said.
