The Food and Drug Administration recently approved a new nonhormonal medication to relieve hot flashes and night sweats in women experiencing menopause. Brisdelle contains paroxetine, the active ingredient in the antidepressant Paxil. Some antidepressants can cause physiological and psychological changes when discontinued.
Brisdelle was approved despite an FDA panel voting against it.
Dr. Patricia Moorman, an associate professor in community and family medicine at Duke University, explains the new drug and what it means for women who suffer from hot flashes.

I think that the initial thought was that the clinical trial showed a very modest benefit. Sometimes drugs work very well for some women and not at all for others. It’s just providing another option for women with hot flashes.
Q: Brisdelle contains 7.5 mg of paroxetine, which is slightly less than Paxil’s lowest dose. Is this going to make a significant decrease in the negative side effects associated with Paxil?
Doctors want to use the lowest effective dose for an indication. Response to drugs is very individualized. In the clinical trials, the side effects were headache, fatigue, nausea and vomiting, which are very common side effects for most drugs.
Q: How long has paroxetine has been prescribed by gynecologists for its off-label treatment of hot flashes?
Several years now. I think that I recall a clinical trial from about 10 years ago.
Q: Why would women be interested in this new drug?
There are many women who are unable or unwilling to take hormones. This is the first nonhormonal drug that treats hot flashes.
Q: Is Brisdelle more or less effective than other drugs that contain hormones and serve the same purpose?
They’re different drugs, but they do the same thing. One is not stronger than the other.
