Migraine-prevention injector now available

Last week, the FDA approved the drug Aimovig for migraine treatment. And Monday, Dr. Lauren Natbony, a neurologist, wrote her first prescription for a patient.

"Before now, there was nothing that would work faster to prevent migraines, meaning decrease their overall frequency over time," Dr. Natbony said. "So we find that very exciting in the headache community."

Amiovig works by blocking the chemical protein in the brain that causes migraines to form. The drug is administered once a month by injection into either the thigh or the upper arm with a device similar to an EpiPen.

But with excitement comes caution for the millions who suffer from migraines. Aimovig is not a cure. It helps to significantly reduce the frequency of migraines and those symptoms that sufferers say can be unbearable.

The list price of Aimovig is $575 for the monthly dose. That comes to $6,900 per year. A patient's out-of-pocket expense will depend on insurance coverage.

The side effects appear to be minimal.

Still, Dr. Natbony said this is a huge breakthrough in migraine treatment and you should not give up.

"We have a lot in the future of migraine treatment and even now we still have medications that can work," Dr. Natbony said. "And definitely making sure if you're suffering, seeing a headache specialist. Really, you don't have to suffer and you don't have to suffer alone."
