Savella for Fibromyalgia

Savella (milnacipran) was FDA-approved in January 2009 as a fibromyalgia treatment. At that time, it was a new drug to the U.S. marketplace. Because it's so new, there's no generic form available yet.

Savella is a serotonin-norepinephrine reuptake inhibitor, or SNRI. By definition, SNRIs are antidepressants. However, Savella isn't approved for depression in the U.S. So far, fibromyalgia is its only approved use in the states.

However, milnacipran is sold as an antidepressant in Europe under several brand names, including Dalcipran, Ixel, and others. Milnacipran drugs have been available in foreign markets for more than a decade and are approved for depression in more than 50 countries.

What Savella Does

Savella increases levels of the neurotransmitters serotonin and norepinephrine, which can be low in people with fibromyalgia. That puts it in the same class as Cymbalta, which is FDA-approved for fibromyalgia, neuopathic pain, depression, and a handful of other conditions.

Savella, however, is the reported to increase norepinephrine more than serotonin.

The New Drug Application for Savella, filed in December of 2007, included data from two Phase III trials involving more than 2,000 patients. The company says data showed Savella was more effective than a placebo and was well tolerated. There were no deaths during the course of the studies and the majority of side effects were described as mild to moderate.

Later studies have supported early results, showing a significant improvement in symptoms, including pain, fatigue, and sleep. However, a 2015 review concluded that it's only effective for about 40 percent of those who take it. That's similar to the effectiveness rates for Cymbalta and the other FDA-approved fibromyalgia drug, Lyrica (pregabalin).

Savella Dosage

The recommended dosage of Savella is 100 mg or 200 mg per day, split into two doses. It's typical to start at a smaller dosage and gradually work up to the full amount.

It's not safe to suddenly stop taking Savella. If you want to go off of the drug, be sure to talk to your doctor about the proper weaning procedure.
