Treatment of Decreased Libido in Women
Start with non-hormonal vaginal lubricants and moisturizers for any concurrent vaginal symptoms, then proceed to psychosexual therapy (which succeeds in 50-80% of cases), and consider flibanserin for premenopausal women or DHEA for postmenopausal women if first-line approaches are insufficient. 1
Initial Assessment: Identify Reversible Causes
Before initiating treatment, systematically evaluate for modifiable contributors:
Menopausal and Vaginal Symptoms:
- Screen for vaginal dryness, dyspareunia, and atrophic vaginitis, which affects approximately 50% of postmenopausal women and directly impairs sexual desire 1, 2
- Unlike hot flashes, vaginal atrophy symptoms persist indefinitely without treatment 1
Medication Review:
- Antidepressants (particularly SSRIs), narcotics, and hormonal therapies commonly impair libido 1, 2
- This is a frequently overlooked but reversible cause 1
Psychological Factors:
- Assess for anxiety, depression, distress, body image concerns, relationship issues, and partner sexual dysfunction 1, 3, 2
- These psychological factors are common contributors and must be addressed for successful treatment 1
Medical Comorbidities:
- Evaluate for cardiovascular disease, diabetes, obesity, smoking, and alcohol abuse as traditional risk factors 3, 2
Treatment Algorithm
First-Line: Address Vaginal Symptoms
For all women with vaginal dryness or dyspareunia:
- Water-, oil-, or silicone-based vaginal lubricants and moisturizers are the recommended first-choice treatments 1, 3, 2
- Silicone-based products last longer than water-based or glycerin-based alternatives 3
- For postmenopausal women, vaginal estrogen (pills, rings, or creams) is the most effective treatment for vaginal dryness leading to sexual dysfunction 3
Pelvic floor physical therapy:
- Improves sexual pain, arousal, lubrication, orgasm, and satisfaction 3
- Particularly valuable for dyspareunia 3
Second-Line: Psychosexual Therapy
Psychosexual therapy demonstrates successful outcomes in 50-80% of patients and can be used alone or combined with physical therapies. 1, 2
Specific psychological approaches with evidence:
- Cognitive behavioral therapy (CBT) has demonstrated effectiveness for improving sexual functioning in women with low libido 3, 4
- Mindfulness has excellent evidence for improving low sexual desire 4
- Psychoeducational support, sexual counseling, and marital/couples therapy address relationship issues and psychological factors 3
Pharmacological Options
For Premenopausal Women:
Flibanserin (ADDYI):
- FDA-approved for acquired, generalized hypoactive sexual desire disorder in premenopausal women 1, 3, 2
- Results in approximately one additional satisfying sexual event every two months 3
- Critical safety warnings: 5
- Must be taken only at bedtime (never during waking hours)
- Absolutely no alcohol consumption close to bedtime dose or until the following day
- Contraindicated with moderate or strong CYP3A4 inhibitors (including fluconazole, erythromycin, diltiazem, verapamil, and many HIV medications)
- Contraindicated in liver disease
- Risk of severe hypotension, syncope, and CNS depression
- Not for use during breastfeeding
Bremelanotide:
- FDA-approved alternative for premenopausal women with hypoactive sexual desire disorder 3
- Administered as subcutaneous injection as needed before anticipated sexual activity 3
Off-label options with limited evidence:
- Bupropion may be considered as second-line despite limited safety and efficacy data 3
- Buspirone may be considered as second-line despite limited data 3
For Postmenopausal Women:
DHEA supplementation:
- 10-50 mg daily can be considered for persistent lack of libido and/or low energy levels 1, 2
- Vaginal DHEA (prasterone) has shown significant improvements in sexual desire, arousal, pain, and overall sexual function 3
Transdermal testosterone:
- Evidence supports use for low desire in postmenopausal women 4
Special Populations
Cancer Survivors:
- Sexual dysfunction affects at least 50% of women cancer survivors and is multifactorial 1
- Sexual health should be included in survivorship care plans, as this is frequently overlooked 1, 2
- For breast cancer survivors on aromatase inhibitors, vaginal dryness is significantly more common (18%) compared to tamoxifen (8%) 1
- Do not prescribe hormonal contraception to breast cancer survivors; use alternative non-hormonal methods 2
- Ospemifene may be considered for dyspareunia in survivors of cancers that are not hormonally sensitive 3
Critical Pitfalls to Avoid
Do NOT:
- Obtain testosterone levels in women in non-research settings—this is not recommended 1
- Prescribe PDE5 inhibitors (sildenafil) for female sexual dysfunction due to lack of effectiveness data 3
- Use vaginal laser therapy due to limited safety and effectiveness data and lack of FDA approval 3
- Prescribe hormonal therapies to women with estrogen-dependent cancers 3
- Overlook medication-induced sexual dysfunction, particularly from antidepressants and endocrine therapies 1
- Ignore vaginal symptoms, as dyspareunia and vaginal dryness contribute to sexual avoidance 3
When to Refer
Consider referral to a specialist menopause service when symptoms are refractory to initial management or when complex hormonal issues are present 1
