Can a Female Take Sildenafil?
No, sildenafil is not recommended for female sexual dysfunction, including sexual arousal disorder, because randomized controlled trials have shown contradictory results and insufficient evidence of effectiveness. 1, 2
Guideline Position on Sildenafil for Women
The National Comprehensive Cancer Network (NCCN) Survivorship Panel explicitly does not recommend oral phosphodiesterase type 5 inhibitors (PDE5i) like sildenafil for female sexual dysfunction. 1, 2 Although sildenafil theoretically increases pelvic blood flow to the clitoris and vagina, the clinical trials have produced contradictory results in women with sexual arousal disorder, and more research is needed before any recommendation can be made. 1, 2
Why the Evidence Fails to Support Use
The largest and highest-quality trial enrolled 577 estrogenized and 204 estrogen-deficient women with female sexual arousal disorder (FSAD) and found no significant differences between sildenafil and placebo for any patient or partner endpoints, including global efficacy questions, sexual event logs, life satisfaction measures, or sexual function questionnaires. 3 This 2002 randomized controlled trial demonstrated that any genital physiological effect of sildenafil was not perceived as improving the sexual response in women with a broad spectrum of sexual dysfunction. 3
Contradictory Findings in Smaller Studies
While some smaller, earlier studies suggested benefit—including a 2001 pilot study showing improved physiologic measurements and subjective function 4, and a 2001 double-blind crossover study in 51 premenopausal women showing improved arousal and orgasm 5—these findings were not replicated in the larger, more rigorous trial. 3 The contradictory nature of these results is precisely why guidelines recommend against its use. 1, 2
FDA-Approved Alternatives You Should Consider Instead
For premenopausal women with hypoactive sexual desire disorder (HSDD):
- Flibanserin (FDA-approved 2015) for acquired, generalized HSDD 2
- Bremelanotide as a self-administered subcutaneous injection as needed 2
For postmenopausal women with dyspareunia:
- Ospemifene (FDA-approved 2013) for moderate to severe dyspareunia, but contraindicated if known or suspected breast cancer 2
- Prasterone (vaginal DHEA), though also contraindicated with history of breast cancer 2
Evidence-Based Treatment Algorithm for Female Sexual Dysfunction
Step 1: Identify the specific type of dysfunction (desire, arousal, orgasm, or pain disorders), as treatment must be guided to the specific problem. 1, 2
Step 2: Screen for iatrogenic causes:
- Medications that impair desire: hormone therapy, narcotics, serotonin reuptake inhibitors 2
- Depression, anxiety, relationship problems, substance use 2
- Cardiovascular risk factors: diabetes, obesity, smoking, alcohol abuse 2
Step 3: Determine menopausal status, as this fundamentally guides treatment selection. 2
Step 4: Initiate non-pharmacological interventions first:
- Water-, oil-, or silicone-based lubricants and moisturizers for vaginal dryness and sexual pain 1, 2, 6
- Pelvic floor muscle training for sexual pain, arousal, lubrication, orgasm, and satisfaction 1, 2
- Vaginal dilators for vaginismus, sexual aversion disorder, or vaginal stenosis 1, 2
- Sexual/couples counseling and cognitive behavioral therapy 1, 2
Step 5: Consider vaginal estrogen (pills, rings, or creams) for postmenopausal women with vaginal dryness, itching, and dyspareunia. 1, 2
Step 6: Use FDA-approved medications for specific conditions as outlined above. 2
Critical Pitfalls to Avoid
- Do not prescribe sildenafil off-label for female sexual dysfunction, as the evidence does not support its effectiveness despite theoretical mechanisms. 1, 2, 3
- Do not overlook relationship factors, as partner communication and relationship quality significantly impact treatment success. 2
- When using lubricants with latex condoms, only use water-based or silicone-based products—never oil-based, as they degrade latex and cause condom failure. 6
- Do not assume all sexual dysfunction is the same; treatment must target the specific type of problem (desire vs. arousal vs. orgasm vs. pain). 1, 2
Special Populations Where Sildenafil Might Be Considered
One small case series suggested sildenafil may reverse antidepressant-induced sexual dysfunction (anorgasmia or delayed orgasm) in women, with significant improvement at 50-100 mg doses. 7 However, this remains off-label use without guideline support, and FDA-approved alternatives should be prioritized first. 2
