While hormone therapy remains the most effective treatment for hot flashes and night sweats, it is not an option for everyone. Some women have medical contraindications (like a history of breast cancer or blood clots). Others simply prefer not to use hormones. Either way, you are not without good options.
The landscape of non-hormonal treatments has changed dramatically in recent years. The North American Menopause Society now recognizes several non-hormonal options as effective alternatives. Two new medications have been specifically designed and FDA-approved for menopausal hot flashes, and several off-label medications have solid evidence behind them. Here is what works, how each option works, and who each one is best suited for.
The New Generation: NK3 Receptor Antagonists
These represent the most significant advance in non-hormonal menopause treatment in decades. They work by targeting the neurokinin 3 (NK3) receptor in the brain’s thermoregulatory center, the same pathway that becomes dysregulated when estrogen declines, causing hot flashes and night sweats. Cleveland Clinic's perimenopause resource provides a helpful overview of how these hormonal changes trigger symptoms.
Elinzanetant (Lynkuet)
FDA-approved in October 2025 for moderate to severe hot flashes from menopause, elinzanetant is the newest non-hormonal option.
- How it works: A dual NK1/NK3 receptor antagonist. It is approved for hot flashes, not as a sleep treatment.
- Effectiveness: Clinical trials showed significant reduction in both the frequency and severity of hot flashes.
- Bedtime dosing: It can cause sleepiness, so it is taken at bedtime.
- Side effects: Common side effects in trials included headache and fatigue. Ask about the full list of warnings before starting.
Fezolinetant (Veozah)
FDA-approved in 2023, fezolinetant was the first medication in this new class.
- How it works: A selective NK3 receptor antagonist that targets the brain’s temperature control center.
- Effectiveness: Reduces hot flash frequency by approximately 50-60% and severity significantly in clinical trials.
- Boxed warning: Since December 2024, Veozah has carried an FDA boxed warning for serious liver injury. Liver blood tests are needed before starting and regularly during the first 9 months (see below).
- Side effects: Most common include abdominal pain, diarrhea, insomnia, and back pain.
Fezolinetant Liver Monitoring
Fezolinetant (Veozah) carries an FDA boxed warning for serious liver injury. If you are prescribed it, you need liver blood tests before starting, every month for the first 2 months, and then at months 3, 6, and 9. Stop taking it and seek care right away if you notice signs of liver problems, such as yellowing skin or eyes, dark urine, pain in the upper right belly, or unusual fatigue.
SSRIs and SNRIs (Mostly Off-Label)
Certain antidepressants have been found to reduce hot flash frequency by 25-50%, even in women who are not depressed. For women who can use hormones, hormone therapy remains more effective, but these medications fill an important gap. They work by modulating serotonin and norepinephrine, neurotransmitters involved in the brain’s temperature regulation.
- Paroxetine (low-dose/Brisdelle): The only SSRI FDA-approved for hot flashes (at a 7.5 mg dose, lower than the antidepressant dose). Reduces hot flash frequency by approximately 33-50%.
- Venlafaxine (Effexor): An SNRI with good evidence for hot flash reduction, used off-label. Because it is also an antidepressant, some clinicians consider it when mood symptoms are present too.
- Escitalopram (Lexapro) and citalopram (Celexa): Both have shown effectiveness in clinical trials for hot flash reduction.
Who they are best for: Women who experience significant mood or anxiety symptoms alongside hot flashes may find that one medication helps with both, though depression or anxiety deserves its own assessment. They are also a good option for women with a history of breast cancer, for whom HRT is typically contraindicated.
Important note: Paroxetine should not be used by women taking tamoxifen for breast cancer, as it interferes with tamoxifen metabolism. All antidepressants, including low-dose paroxetine, carry an FDA boxed warning about suicidal thoughts in young people.
Gabapentin and Pregabalin
Originally developed for seizures and nerve pain, gabapentin is used off-label for hot flashes and has been found to reduce hot flash frequency by approximately 30-50%.
- Best for: Women whose primary issue is night sweats that disrupt sleep. It commonly causes drowsiness, which is one reason it is usually taken at bedtime.
- Dosing: Typically 300-900 mg at bedtime for hot flashes (lower than doses used for pain or seizures).
- Side effects: Drowsiness, dizziness, and fatigue, which often improve over the first 1-2 weeks. Gabapentin has some potential for misuse, and the FDA warns of serious breathing problems when it is combined with opioids or other sedatives.
- Pregabalin (Lyrica): Similar mechanism, used off-label, with more limited evidence for hot flash reduction. It is a controlled substance and can cause similar side effects.
CBT for Hot Flashes
Cognitive Behavioral Therapy specifically designed for hot flashes (not general CBT) has strong clinical evidence. It does not reduce the physiological hot flash itself but significantly changes how distressing and disruptive hot flashes feel. Research from King’s College London showed that women who completed a CBT program reported significantly less bother from hot flashes and better sleep, even though the actual number of hot flashes remained similar.

How to Choose
The right non-hormonal medication depends on your specific situation:
- Hot flashes as primary concern: Elinzanetant (Lynkuet) or fezolinetant (Veozah) are the most effective non-hormonal options specifically designed for this purpose.
- Hot flashes + mood/anxiety: An SSRI or SNRI may address both simultaneously.
- Night sweats + sleep disruption: Gabapentin (off-label) or elinzanetant, both usually taken at bedtime, may be worth discussing.
- Breast cancer history: SSRIs (except paroxetine if on tamoxifen), elinzanetant, or fezolinetant are options. Discuss with your oncologist.
- Prefer non-medication approach: CBT for hot flashes combined with lifestyle changes can provide meaningful relief.
What Non-Hormonal Medications Don’t Do
It is important to be clear about limitations. Non-hormonal medications are primarily effective for hot flashes and night sweats. They do not address:
- Vaginal dryness and atrophy (local vaginal estrogen is needed for this)
- Bone loss prevention (only HRT and specific osteoporosis medications do this)
If your symptoms extend beyond hot flashes, a combination approach that pairs non-hormonal medications with lifestyle changes, local vaginal estrogen, and/or supplements may serve you best.
The Bottom Line
If you can’t or prefer not to use hormone therapy, you still have effective options. The NK3 receptor antagonists (elinzanetant and fezolinetant) are a genuinely new option, though each has its own side effects and fezolinetant requires regular liver monitoring. Combined with the right off-label medications and behavioral approaches, non-hormonal treatment can provide meaningful relief for the most disruptive perimenopause symptoms.
