There isn’t a single “best” antidepressant for menopause because the right choice depends on whether your main problem is hot flashes, mood changes, or both. That said, two classes of antidepressants, SSRIs and SNRIs, have strong evidence behind them and are recommended by the North American Menopause Society as first-line nonhormonal options for vasomotor symptoms like hot flashes and night sweats.
How Antidepressants Help With Menopause
Antidepressants weren’t originally designed for hot flashes, but they turned out to be surprisingly effective at reducing them. SSRIs and SNRIs work by changing how your brain regulates serotonin and norepinephrine, two chemical messengers that play a role in your body’s temperature control system. When estrogen drops during menopause, that system becomes unstable, and these medications help compensate.
Both SSRIs and SNRIs typically start reducing hot flashes within the first two weeks of treatment. Studies show they can cut the frequency and severity of hot flashes by 25% to 66%, though this is generally less effective than estrogen therapy. For women who can’t or don’t want to take hormones, antidepressants are one of the strongest alternatives available.
The Only FDA-Approved Option for Hot Flashes
Low-dose paroxetine (sold as Brisdelle) is the only antidepressant specifically FDA-approved for treating menopausal hot flashes. It uses a 7.5 mg dose taken at bedtime, which is significantly lower than the doses used to treat depression.
In clinical trials involving over 1,100 postmenopausal women who were experiencing at least 7 to 8 moderate-to-severe hot flashes per day, Brisdelle reduced daily hot flash frequency by about 5 to 6 episodes over 12 weeks, compared to 4 to 5 with placebo. By week 24, 48% of women on Brisdelle had cut their hot flash frequency in half, versus 36% on placebo. The most common side effects were headache (6.3%), fatigue (4.9%), and nausea (4.3%). Because the dose is so low, it tends to cause fewer of the side effects people associate with antidepressants at full strength.
SNRIs: Better for Combined Symptoms
If you’re dealing with both hot flashes and depression or anxiety, an SNRI may be a better fit. SNRIs like venlafaxine and desvenlafaxine act on both serotonin and norepinephrine, which gives them a dual benefit. Notably, research shows that SNRIs don’t require the addition of estrogen to work effectively against menopausal depression, whereas SSRIs tend to work better for major depression when combined with estrogen.
Desvenlafaxine has been studied specifically for menopausal hot flashes in a meta-analysis of randomized controlled trials. At 100 mg per day, it produced a significant reduction in moderate-to-severe hot flashes, and the effect grew stronger over time, with greater improvement at 26 weeks than at 12 weeks. It appeared both safe and effective for up to 12 months of use. Venlafaxine, a closely related medication, is also widely prescribed for this purpose and is one of the most commonly used nonhormonal options in clinical practice.
SSRIs: A Good Choice for Milder Symptoms
SSRIs like paroxetine, citalopram, escitalopram, and sertraline are effective for hot flashes and are often preferred when anxiety is the dominant mood symptom. They tend to have a slightly gentler side effect profile than SNRIs for some women, though individual responses vary widely.
One important distinction: SSRIs appear to be more effective at treating menopausal depression when paired with estrogen therapy. If you’re taking an SSRI for mood and not using any form of hormone therapy, your doctor may want to monitor whether the antidepressant alone is doing enough for your mood symptoms.
A Key Concern for Breast Cancer Survivors
If you’re taking tamoxifen for breast cancer, your antidepressant choice matters more than most. Tamoxifen is converted into its active form by a liver enzyme called CYP2D6, and some antidepressants block that same enzyme, potentially reducing tamoxifen’s effectiveness. Paroxetine and fluoxetine are the strongest inhibitors of this enzyme.
Citalopram and venlafaxine are among the weakest inhibitors, which is why they’re generally recommended for women on tamoxifen. Research suggests that citalopram in particular can be prescribed alongside tamoxifen with little to no effect on breast cancer recurrence risk. If you’re in this situation, the choice of antidepressant is something to discuss carefully with your oncologist.
What the Guidelines Recommend
The 2023 position statement from the North American Menopause Society gives SSRIs and SNRIs a Level I recommendation (the highest level, meaning good and consistent scientific evidence) for treating vasomotor symptoms without hormones. They sit alongside cognitive-behavioral therapy, clinical hypnosis, gabapentin, and fezolinetant (a newer non-antidepressant medication) as recommended options.
Notably, the same guidelines found that many popular alternatives don’t hold up. Herbal supplements, soy extracts, acupuncture, yoga, and paced breathing were all rated “not recommended” based on the available evidence. Exercise, while beneficial for general health, also didn’t show reliable effects on hot flashes specifically.
Choosing Between Options
The practical decision usually comes down to your symptom profile:
- Primarily hot flashes, no mood issues: Low-dose paroxetine (Brisdelle) is the most targeted option, with FDA approval and a low side-effect burden.
- Hot flashes plus depression: An SNRI like venlafaxine or desvenlafaxine addresses both without necessarily needing estrogen added for the mood component.
- Hot flashes plus anxiety: An SSRI like escitalopram or sertraline can handle both, though adding estrogen may improve mood outcomes.
- Taking tamoxifen: Citalopram or venlafaxine are the safest choices to avoid drug interactions.
Most women notice improvement in hot flashes within two weeks, but the full effect on mood symptoms typically takes four to six weeks, similar to treating depression in any other context. If one medication doesn’t work well or causes bothersome side effects, switching to a different one in the same class, or switching between an SSRI and SNRI, is common and often successful. The “best” antidepressant for menopause is ultimately the one that matches your specific combination of symptoms with the fewest side effects for you personally.
