The U.S. Food and Drug Administration approved Veozah (fezolinetant), an oral medication for the treatment of moderate to severe vasomotor symptoms, or hot flashes, caused by menopause. Veozah is of the first neurokinin 3 (NK3) receptor antagonists approved by the FDA to treat moderate to severe hot flashes from menopause. It works by binding to and blocking the activities of the NK3 receptor, which plays a role in the brain’s regulation of body temperature.
Some women who experience hot flashes and have a history of vaginal bleeding, stroke, heart attack, blood clots or liver disease, cannot take hormone therapies. Veozah is not a hormone. It targets the neural activity which causes hot flashes during menopause.
Patients taking Veozah should take one 45 milligram pill orally, once a day, with or without food. The pill should be taken at the same time each day. If a dose is missed, or not taken at the regular time, patients should take it as soon as possible and return to their regular schedule the following day.
The effectiveness of Veozah to treat moderate to severe hot flashes was demonstrated in each of the first 12-week, randomized, placebo-controlled, double-blind portions of two phase 3 clinical trials. In both trials, after the first 12 weeks, the women on placebo were then re-randomized to Veozah for a 40-week extension study to evaluate safety. Each trial ran a total of 52 weeks. The average age of the trial participants was 54 years old.
The prescribing information for Veozah includes a warning for elevated hepatic transaminase, or liver injury. Before using Veozah, patients should have blood work done to test for liver damage. While on Veozah, routine bloodwork should be performed every three months for the first nine months of using the medication. Patients experiencing symptoms related to liver damage—such as nausea, vomiting, or yellowing of the skin and eyes—should contact a physician. Veozah cannot be used with CYP1A2 inhibitors. Patients with known cirrhosis, severe renal damage or end-stage renal disease should not take Veozah.
The most common side effects of Veozah include abdominal pain, diarrhea, insomnia, back pain, hot flush and elevated hepatic transaminases.
