Non-Hormonal Therapy for Perimenopause
For perimenopausal women with bothersome vasomotor symptoms, start with SNRIs/SSRIs (venlafaxine, paroxetine, escitalopram, or citalopram) or gabapentin as first-line pharmacologic therapy, which reduce hot flashes by 40-65%. 1, 2
Pharmacologic Options for Vasomotor Symptoms
First-Line Medications
- SNRIs/SSRIs are the preferred non-hormonal medications, with venlafaxine showing particular efficacy in reducing hot flashes by approximately 40-65% 1, 2
- Paroxetine is FDA-approved specifically for vasomotor symptoms and reduces hot flash frequency by 40-65% 2, 3
- Escitalopram and citalopram are effective alternatives with similar efficacy 1, 2
- Desvenlafaxine (SNRI) also reduces vasomotor symptoms by 40-65% 2
Critical caveat: Do not use SSRIs (particularly paroxetine) in women taking tamoxifen, as SSRIs interfere with tamoxifen metabolism and reduce its efficacy 3
Second-Line Medications
- Gabapentin effectively reduces hot flashes and is particularly useful for women with sleep disturbances related to night sweats 1, 2
- Pregabalin was previously recommended but is no longer advised per The Menopause Society's 2025 updated guidelines 4
- Clonidine can be used but is no longer a primary recommendation per updated 2025 guidelines 1, 4
Emerging Therapies
- Neurokinin B antagonists represent a new medication class specifically targeting vasomotor symptoms, with additional benefits for sleep and mood disturbances 4
Non-Pharmacologic Interventions
Lifestyle Modifications (First-Line Approach)
- Environmental modifications: Keep rooms cool, dress in layers, use fans 1, 3
- Avoid triggers: Hot beverages, spicy foods, alcohol, caffeine, and stress 1
- Regular physical activity helps reduce symptom severity 1
Evidence-Based Behavioral Therapies
- Cognitive behavioral therapy (CBT) is effective for short-term reduction of vasomotor symptoms and associated sleep disturbances 5, 3
- Clinical hypnosis shows efficacy for short-term vasomotor symptom reduction 3
- Mind-body interventions are effective non-pharmacological options 5
- Acupuncture has demonstrated some efficacy in reducing hot flashes 5, 1
Important limitation: Data are lacking to support herbal/botanical supplements, and phytoestrogens show no convincing evidence of benefit 5
Management of Genitourinary Symptoms
Vaginal Dryness and Dyspareunia
- Hormone-free vaginal lubricants and moisturizers are first-line therapy: water-based gels, silicone-based lubricants, hyaluronic acid gel 5, 1, 3
- Non-hormonal vaginal moisturizers are noninferior to estrogen-based therapies for treating genitourinary syndrome of menopause 3
- Vaginal dilators can be used for dyspareunia secondary to vaginal atrophy 1
- Topical vitamin D or E may provide comfort 5
When Non-Hormonal Measures Fail
- Low-dose vaginal estrogen (rings, suppositories, creams) improves symptom severity by 60-80% and does not increase breast cancer recurrence risk 5, 1, 2
- Ospemifene (oral SERM) improves GSM symptom severity by 30-50% 2
- Intravaginal dehydroepiandrosterone (DHEA/prasterone) improves symptom severity by 40-80% 2
Sleep Disturbances
- Melatonin is recommended for sleep disturbances associated with perimenopause 5
- Gabapentin addresses both vasomotor symptoms and sleep disruption 1, 2
- CBT effectively treats sleep disturbances related to menopausal symptoms 5, 3
Assessment Before Treatment
Essential Evaluations
- Screen for medical causes: thyroid disease, diabetes that may mimic or exacerbate menopausal symptoms 5, 1
- Assess hormone levels as clinically indicated: estradiol, FSH, LH, prolactin 5, 1
- Note: FSH is unreliable in women with prior chemotherapy, pelvic radiation, or those taking tamoxifen 5
Risk Assessment
- Bone density assessment should be considered, especially with early menopause or osteoporosis risk factors 1
- Evaluate for contraindications to hormone therapy: history of hormone-dependent cancers, recent breast cancer, active liver disease, abnormal vaginal bleeding, thromboembolic events 5, 1
Treatment Algorithm
- Start with lifestyle modifications and environmental controls for all women 1, 3
- For bothersome vasomotor symptoms: Initiate SNRI/SSRI (venlafaxine or paroxetine preferred) or gabapentin 1, 2
- For vaginal symptoms: Begin with non-hormonal lubricants and moisturizers 5, 3
- Add behavioral therapies: CBT or clinical hypnosis for additional symptom control 3
- Consider neurokinin B antagonists as emerging option for refractory vasomotor symptoms 4
- For persistent genitourinary symptoms: Consider low-dose vaginal estrogen, ospemifene, or vaginal DHEA 2, 3
Key principle: Non-hormonal therapies show moderate efficacy (40-65% reduction) compared to hormone therapy (75% reduction), but are appropriate for women with contraindications to hormones or those who prefer non-hormonal approaches 5, 2
