What it is
Hot flashes start in the brain, not the ovaries. Falling estrogen makes the brain's thermostat oversensitive, so small triggers set off a full flush. Medications that calm that circuit can help without touching hormones.
The FDA has approved hormone-free prescriptions for hot flashes (the clinical term is vasomotor symptoms). Fezolinetant blocks the brain signal that fires a flash. Low-dose paroxetine steadies the same thermostat a different way.
These options matter most for women who cannot take estrogen, such as after breast cancer or a blood clot. They also fit women who simply prefer not to.

Questions people ask
- What is fezolinetant?
- A daily pill, sold as Veozah, FDA-approved in 2023 for hot flashes. It blocks a brain signal that triggers them. It contains no hormones.
- Do antidepressants really help hot flashes?
- Yes, at low doses. Low-dose paroxetine is FDA-approved for hot flashes, and it works even in women who are not depressed.
- How well do non-hormonal options work?
- They cut hot flashes meaningfully, though usually less than estrogen. Estrogen remains the most effective treatment for hot flashes.
- Are there side effects?
- Fezolinetant needs periodic liver blood tests. Low-dose paroxetine can cause nausea early on, which usually fades.
- Can I take these with tamoxifen?
- Paroxetine is avoided with tamoxifen because it can blunt its effect. Other options exist; sorting this out is what the first visit is for.
- What about supplements like black cohosh?
- The evidence is weak, and supplements are not FDA-reviewed. Dr. Mueller sticks to treatments with solid trials behind them.
