Please describe a good medication for migraine prevention?

Some antidepressants: Certain antidepressants in low doses are acceptable for migraine prevention. The tricyclics such as Elavil (amitriptyline) are a particular class that have been used for years. They work better over a longer period of time and as such should be used primarily under a physician supervision.

Preventive drugs: You may want to try petadolex, a herbal extract of the butterbur plant, level a (highest) recommended by the american headache society in 2012.
