Treatment of Low Female Libido (Hypoactive Sexual Desire Disorder)
For premenopausal women with HSDD, flibanserin (100 mg at bedtime) is the only FDA-approved first-line treatment, though it provides modest benefit of approximately one additional satisfying sexual event every two months. 1, 2
FDA-Approved Pharmacological Options
Flibanserin (First-Line)
- FDA-approved specifically for premenopausal women with acquired, generalized HSDD that causes marked distress and is NOT due to medical/psychiatric conditions, relationship problems, or medication effects 2
- Dosing: 100 mg once daily at bedtime only—never during waking hours due to increased risk of hypotension and syncope 2
- Absolute contraindications: alcohol consumption (must avoid until the following day after dosing), moderate-to-strong CYP3A4 inhibitors (including common antifungals like fluconazole, HIV medications, certain antibiotics like ciprofloxacin and erythromycin), and liver disease 2
- Expected benefit: approximately 1 additional satisfying sexual event every 2 months compared to placebo 1
- Common side effects: CNS depression, somnolence, hypotension, and syncope—patients must lie down immediately if experiencing lightheadedness 2
Bremelanotide (Alternative FDA-Approved Option)
- FDA-approved melanocortin receptor agonist for premenopausal women with HSDD 1
- Administered as subcutaneous injection on an as-needed basis 1
- Can be considered when flibanserin is contraindicated or not tolerated 1
Off-Label Pharmacological Options
When First-Line Fails or Is Contraindicated
- Bupropion: Off-label option with limited but supportive data, particularly helpful in breast cancer survivors 3, 1
- Buspirone: Off-label option considered by expert panels despite limited evidence 1
- Androgens (testosterone/DHEA): May be discussed for low desire, though not FDA-approved for HSDD 3, 1, 4
What NOT to Use
- PDE5 inhibitors (sildenafil, etc.) are NOT recommended for female sexual dysfunction due to contradictory trial results and lack of effectiveness data in women 1, 4
Non-Pharmacological Interventions (Often More Effective)
Psychological Approaches
- Cognitive behavioral therapy (CBT) has strong evidence for improving sexual function, particularly in breast cancer survivors 3, 4
- Psychoeducational support, group therapy, sexual counseling, or couples therapy should be offered to all women with sexual complaints 3
- Mindfulness-based therapies show promise 6
Mechanical and Physical Interventions
- Vibrators or clitoral stimulatory devices with specialist referral for orgasm difficulties 3, 1
- Pelvic physical therapy (pelvic floor muscle training) improves sexual pain, arousal, lubrication, orgasm, and satisfaction 3, 4
- Vaginal dilators for pain during sexual activity or vaginal stenosis from pelvic radiation 3
Addressing Vaginal Symptoms
- Non-hormonal water-based lubricants and moisturizers as primary treatment for vaginal dryness 3, 4
- Topical anesthetics (lidocaine) applied to vulvar vestibule before penetration for dyspareunia 3
- Vaginal estrogen is most effective for vaginal dryness but contraindicated in hormone-sensitive breast cancer 3
- Ospemifene for dyspareunia in postmenopausal women without hormone-sensitive cancers 3, 1
Lifestyle Modifications
- Integrative therapies (yoga, meditation) help alleviate anxiety that impacts sexual function 3, 4
- Address modifiable risk factors: smoking cessation, alcohol reduction, obesity management 4
- Regular exercise, stress management, adequate sleep, and healthy diet 4
Critical Assessment Steps
Identify Reversible Contributing Factors
- Medications: SSRIs/SNRIs (cause anorgasmia and reduced libido), beta-blockers, narcotics, hormone therapy 3, 4
- Medical conditions: cardiovascular disease, diabetes, thyroid disorders, depression, anxiety 4
- Menopausal status: vaginal atrophy and dryness significantly impact function 3, 4
- Relationship issues: quality of partner relationship is crucial 3, 5
- History of trauma: physical or sexual abuse 5
Special Population: Cancer Survivors
- Avoid hormonal treatments in hormone-sensitive cancer survivors (breast, endometrial) 1, 4
- For those on aromatase inhibitors, vaginal estrogen may counteract AI efficacy—if needed, use estriol-containing preparations rather than estradiol 3
- Consider stopping SSRIs/SNRIs if contributing to dysfunction 3
- Pelvic physical therapy particularly beneficial for gynecologic cancer survivors 3
Treatment Algorithm
- Rule out and address reversible causes: medication review, treat depression/anxiety, address relationship issues 3, 4
- For vaginal dryness/dyspareunia: Start with non-hormonal lubricants/moisturizers; consider vaginal estrogen if no contraindications 3, 4
- For low desire in premenopausal women: Flibanserin 100 mg at bedtime (if no contraindications) or bremelanotide 1, 2
- If first-line fails or contraindicated: Consider off-label bupropion or buspirone 1
- Concurrent psychological intervention: CBT, sexual counseling, or couples therapy for all patients 3, 4
- For orgasm difficulties: Mechanical devices (vibrators) plus pelvic physical therapy 3, 1
Common Pitfalls to Avoid
- Do not prescribe flibanserin without counseling about absolute alcohol prohibition—combination causes severe hypotension and syncope 2
- Do not use PDE5 inhibitors—they are ineffective in women despite effectiveness in men 1, 4
- Do not prescribe vaginal estrogen to women on aromatase inhibitors without careful consideration—may reverse AI efficacy 3
- Do not expect dramatic pharmacological results—current medications provide modest benefit at best; psychological and mechanical interventions often more effective 1, 6
- Do not overlook partner involvement—sexual dysfunction often has relational components requiring couples therapy 3
