Millions suffer from migraine headaches and rely on prescription medications, but not all medicines work for everyone.
Now scientists say there's a new medication that goes straight to the source of a migraine.
It's known as Telcagepant and it's showing remarkable results.
Researchers say it's the first drug that targets the cause of the migraine, a chemical imbalance in the brain and not just the symptoms.
Telcagepant is produced by the Merck Pharmaceutical company and should be available next year.
