The strongest hormone-free options, in order of trial effect size: fezolinetant (~60–65% reduction), venlafaxine ER 75 mg (~50–60%), low-dose paroxetine 7.5 mg — the only FDA-approved non-hormonal SSRI for this use — and escitalopram (~45–55%), gabapentin 900 mg nightly (~45%, best for night-dominant symptoms), and oxybutynin 2.5–5 mg twice daily (~60% in ACCRU, useful after breast cancer). CBT reliably reduces how much flashes bother you rather than how often they happen. Black cohosh and most supplements do not beat placebo.
Prescription options, ranked
Fezolinetant (Veozah)
Largest effect of any hormone-free option, fastest onset, and mechanism-specific. Requires liver monitoring and is expensive without coverage. Full detail: Veozah guide.
Venlafaxine ER (SNRI)
75 mg daily is the best-evidenced generic. In MsFLASH it reduced flashes by 2.3/day versus 2.8 for low-dose estradiol and 1.8 for placebo — remarkably close to hormones for a non-hormonal drug. Watch blood pressure at higher doses and taper rather than stopping abruptly.
Paroxetine mesylate 7.5 mg
The only non-hormonal product FDA-approved for vasomotor symptoms. The dose is below the antidepressant range, so sexual side effects and weight change are less common. Do not use with tamoxifen.
Escitalopram 10–20 mg
Solid randomized evidence, CYP2D6-neutral, and a sensible first pick when low mood or anxiety coexists with flashes.
Gabapentin 300–900 mg at bedtime
Best choice when symptoms are night-dominant. Dizziness and drowsiness are dose-limiting; start low and titrate. See night sweats.
Oxybutynin 2.5–5 mg twice daily
Strong randomized signal in the ACCRU trial, much of it in breast cancer survivors. Dry mouth is common; long-term anticholinergic exposure is a consideration in older women.
Clonidine
Modest benefit, and now largely superseded. Dry mouth, sedation, and rebound hypertension on abrupt withdrawal.
Behavioral treatment that actually has evidence
- CBT. Guideline-recommended. Reduces interference and bother substantially; frequency changes little.
- Clinical hypnosis. Randomized data show reductions in both self-reported and physiologically measured flashes.
- Weight loss and smoking cessation. Both associated with reduced vasomotor burden and worth doing regardless.
- Paced breathing. Popular, but the controlled trials are unimpressive. Harmless, not a plan.
What does not work
Being honest here is the point of this page. Black cohosh, evening primrose oil, dong quai, and vitamin E do not reliably beat placebo. Phytoestrogen supplements show a modest pooled effect with high heterogeneity — a signal that mostly disappears in the better-controlled trials. Compounded hormone pellets are neither non-hormonal nor well controlled; see our compounded HRT policy. Full supplement review: menopause supplements.

What is the most effective non-hormonal treatment for hot flashes?
Fezolinetant (Veozah), a neurokinin 3 receptor antagonist, has the largest effect size at roughly 60-65% reduction. Among generics, venlafaxine ER 75 mg performed best and came close to low-dose estradiol in the MsFLASH head-to-head trial.
Which antidepressant is best for hot flashes?
Venlafaxine ER 75 mg has the strongest data; low-dose paroxetine mesylate 7.5 mg is the only FDA-approved non-hormonal option; escitalopram 10-20 mg is also effective. Avoid paroxetine and fluoxetine if you take tamoxifen — they inhibit CYP2D6 and reduce its activation.
Does gabapentin help hot flashes?
Yes, roughly a 45% reduction in trials, and it is particularly useful when symptoms are mostly nocturnal because the sedation aids sleep. Typical dosing is 300 mg at bedtime titrated to 900 mg, often divided.
Can I take non-hormonal treatment after breast cancer?
Yes, and it is the standard path. Fezolinetant, venlafaxine, gabapentin, oxybutynin and CBT are all used in survivors. Coordinate with your oncologist, and avoid strong CYP2D6-inhibiting SSRIs if you are on tamoxifen.
Does CBT actually reduce hot flashes?
CBT changes the outcome that most affects daily life. In the MENOS trials, group CBT produced a large reduction in hot flash problem-rating with little change in measured frequency — flashes bothered women far less.
Does black cohosh work for hot flashes?
The Cochrane review of about 1,400 participants found no consistent benefit over placebo. Kindr does not recommend or sell black cohosh as a hot flash treatment.
What about clonidine, vitamin E, or acupuncture?
Clonidine has modest effect with dry mouth, sedation and rebound hypertension risk, so it is now a later-line choice. Vitamin E has minimal effect. Acupuncture trials show improvement over waitlist but generally not over sham.
