The estimated 80 percent of women who get hot flashes when going through menopause have a new option to help them get some relief. The treatment is a drug called Veozah, just approved by the

U.S. Food and Drug Administration (FDA). Menopause typically occurs between the ages of 45 and 55. Sudden hot flashes, often accompanied by sweating, flushing and chills, can persist for

many years and disrupt daily life. Research shows that these flares can affect quality of sleep and concentration. They can also interfere with one's ability to work, according to a new

study published in _Mayo Clinic Proceedings_.  “Hot flashes as a result of menopause can be a serious physical burden on women and impact their quality of life,” said Janet Maynard, M.D.,

director of the Office of Rare Diseases, Pediatrics, Urologic and Reproductive Medicine in the FDA’s Center for Drug Evaluation and Research, in a statement. “The introduction of a new

molecule to treat moderate to severe menopausal hot flashes will provide an additional safe and effective treatment option for women.” HOW THE DRUG WORKS The first-of-its-kind pill — called

a neurokinin 3 (NK3) receptor antagonist — works by acting on a part of the brain that helps regulate a person's body temperature. Estrogen helps to keep that part of the brain properly

balanced. When a woman's estrogen levels fall during menopause, the imbalance leads to hot flash symptoms.   “It’s very targeted,” Claudia Mason, M.D., a gynecologist with Cleveland

Clinic, says about the new drug. “And when things are targeted like that, they tend not to have as many side effects because they’re not hitting all over the map.” In clinical trials,

moderate to severe hot flashes were reduced in study participants who took Veozah (fezolinetant). Common side effects of the drug include abdominal pain, diarrhea, insomnia, back pain, hot

flush and elevated hepatic transaminases (liver enzymes). The label on the medication, a pill taken once daily with or without food, includes a warning for liver injury, and the FDA says

patients should have their blood tested for liver damage before taking Veozah.
