Sildenafil for Women

One tool we can try to support physical arousal and orgasm — most helpful when the main issue is physical, especially with SSRI/SNRI-related changes.

Off-label use in women Not FDA-approved for female sexual concerns Does not contain hormones

What it is

Sildenafil is a prescription medicine most people know for helping men with erections. In women, it is considered an off-label use, which means it is not FDA approved for female sexual concerns, but some clinicians use it for certain types of arousal and orgasm difficulties. It does not contain hormones.

What it does

Sildenafil helps increase blood flow to the genital area. It relaxes blood vessels so that during sexual stimulation, there can be more warmth, swelling, sensitivity, and natural lubrication. It does not create desire on its own and does not work without sexual stimulation and arousal.

How it can help

For some women, sildenafil may help with:

Feeling more physical arousal during intimacy
Increased sensitivity
Easier or more intense orgasms
Less time needed to reach orgasm
Tends to help most when

The main issue is physical

  • Physical arousal is the primary concern
  • Orgasm is the primary concern
  • These changes started with an antidepressant (SSRI/SNRI)
Usually less helpful when

The issue is not primarily physical

  • The main concern is low desire or interest alone
  • Stress or relationship concerns are driving it
  • Pain with intimacy is the primary issue
  • Low estrogen-related dryness is the primary issue

In those cases we often look at other options as well.

Before trying sildenafil: optimize hormones first

Sildenafil works by increasing blood flow to the genitals. But for that extra blood flow to actually translate into warmth, swelling, lubrication, and sensitivity, the tissue has to be hormonally responsive. If estrogen is low, the tissue itself is thinner and less responsive — so we can push more blood flow in and the result may still underwhelm.

That’s why the clearest positive trial of sildenafil in postmenopausal women specifically enrolled only women who already had adequate estrogen and testosterone.[4] It wasn’t an accident — the researchers knew sildenafil needed the hormonal foundation in place first.

The usual sequence
1
Address GSM
If vaginal dryness, thinning, or discomfort are part of the picture, vaginal estrogen first. It’s low-risk, inexpensive, and often solves enough of the physical arousal problem that sildenafil isn’t needed.
2
Optimize systemic hormones
If you’re a candidate for systemic hormone therapy and your estradiol or testosterone is suboptimal, we’ll get those into range. Testosterone matters here too — one of the positive sildenafil trials in women used low-dose testosterone alongside it.[11]
3
Then consider sildenafil
If physical arousal or orgasm is still the main issue after hormones are optimized, that’s when sildenafil becomes a more targeted tool — one piece added to a foundation that’s already working.
When this doesn’t apply

If your sexual side effects started with an SSRI or SNRI and you’re premenopausal with no reason to suspect low estrogen, the problem is pharmacologic, not hormonal. In that case we can go to sildenafil without an estrogen workup first — that’s the scenario studied in the strongest positive trial.[5]

How this may relate to antidepressants

Some antidepressants, especially SSRI and SNRI medicines, can affect different parts of sexual response. They may make it harder to feel sexual interest or desire, become physically aroused, lubricate, or reach orgasm.

Two medicines, two different parts of sexual response
Wellbutrin
The “wanting” part

Works differently from SSRI/SNRI medicines and may help with desire or interest — the “wanting” part of sexual response.

Sildenafil
The physical part

Intended to support the physical arousal part — genital blood flow, sensitivity, and orgasm.

For women having both low desire and physical arousal or orgasm concerns related to an SSRI/SNRI, these medicines may sometimes be used together because they address different aspects of sexual function. This approach is individualized, does not work for everyone, and requires a review of your health history and current medicines.

It does not work for everyone, and research in women has shown mixed results. Think of it as one tool we can try to support arousal, not a guaranteed fix.

What the research shows

We want to be honest with you about what the research actually shows. The studies where sildenafil has helped were mostly small, or focused on specific groups of women — women having sexual side effects from antidepressants, women with arousal or orgasm concerns whose hormones were already in a good range, women with nerve injuries from spinal cord damage, and women with diabetes. The larger studies in otherwise healthy women have not shown a clear benefit. Because of that, the main OB-GYN professional organization currently advises against using sildenafil routinely for sexual concerns in women outside of research settings.[1][2][3]

The strongest positive study

The clearest positive study was published in 2008 in a major medical journal. Researchers studied nearly 100 women before menopause whose depression was under control, but who were having sexual side effects from their antidepressants. Women who took sildenafil before intimacy reported meaningfully better sexual function than women who took a placebo. This is the strongest and most reliable evidence we have in women — and it points specifically to women dealing with antidepressant-related sexual side effects as the group most likely to see a real benefit.[5]

Other findings worth knowing

Postmenopausal women whose hormones were already optimized (2003 study of 202 women). When women already had estrogen and testosterone in a good range, sildenafil improved genital sensation and overall sexual satisfaction. Women whose only concern was physical arousal improved on five of six things the researchers tracked. Women who also had low desire did not benefit — another sign that this medicine is for the physical side of things, not for desire.[4]

Sexual side effects from antidepressants (2021 pooled analysis of multiple studies). When researchers pooled data from several different trials together, the overall pattern suggested that sildenafil does help with sexual side effects caused by antidepressants — reinforcing what the 2008 trial found.[8]

Testosterone plus sildenafil, taken together (2018 studies, nearly 500 women). In women whose brains don’t respond strongly to sexual cues, a small dose of testosterone taken alongside sildenafil before intimacy led to more satisfying sexual experiences than a placebo, more than sildenafil alone, and more than testosterone alone. In short — the combination worked better than either one by itself.[11]

A sildenafil cream (2024 study). Researchers also tested a sildenafil cream applied to the genital area instead of a pill. The study did not meet its main goals, but a closer look at women specifically dealing with arousal difficulties showed the cream improved the sensation of arousal and reduced sexual distress compared to a placebo cream. This is still being studied and the cream is not yet widely available.[9][10]

Being honest about the evidence

The studies where sildenafil helped were usually small, or looked at a very specific group of women, or found the positive result as a side finding rather than what the study set out to prove. Only one large, well-designed trial has shown a clear positive result in women — and it was in women whose sexual side effects came from antidepressants. That’s why we talk about this medicine as “one tool to try,” not a routine fix.[2][4][5]

What to expect

How to take it
Usually taken only as needed, about 30 to 60 minutes before sexual activity, and only once in a 24-hour period.
What you may notice
If it helps, you may notice more tingling, fullness, or lubrication with stimulation, and orgasm may feel easier. Some women notice little change.

Common side effects

Headache
Flushing or warmth in the face
Stuffy nose
Mild nausea or heartburn
Dizziness (sometimes)
Rarely: vision changes (bluish tint, light sensitivity)

Who should not take sildenafil

Do not take sildenafil if

Please do not take sildenafil and let me know before trying it if any of these apply to you:

  • You take nitrate medicines for chest pain or heart disease — nitroglycerin (tablets, spray, patches), isosorbide mononitrate or dinitrate, or amyl nitrite (“poppers”). Taking these together with sildenafil can cause a dangerous drop in blood pressure.
  • You take riociguat (Adempas) for lung pressure problems.
  • You have ever had an allergic reaction to sildenafil, Viagra, Revatio, or similar medicines like tadalafil (Cialis) or vardenafil (Levitra).
  • You have been told not to have sexual activity for health reasons — unstable chest pain, recent heart attack or stroke, severe heart failure, very low blood pressure, or uncontrolled high blood pressure.
  • You have retinitis pigmentosa (a rare eye condition) or a history of sudden vision loss.
  • You have sickle cell-related lung hypertension.

Talk with me first if you have

Heart disease, rhythm problems, fainting, severe liver or kidney disease, or take medicines for prostate enlargement, blood pressure, or strong antifungals, antibiotics, or antivirals that can raise sildenafil levels. We’ll review your situation together.

!

If you were prescribed nitrates for an emergency after you have taken sildenafil, tell emergency staff right away that you took sildenafil.

Call 911 for emergencies

If you have chest pain, fainting, severe dizziness, sudden vision or hearing changes, or an allergic reaction (rash, swelling, trouble breathing) — call 911 or go to the nearest emergency room. Do not wait to message the clinic.

This is an individualized decision.

If you’d like to try it, message us through your patient portal to get started. We can review whether it’s safe for you and what else may help alongside it — vaginal estrogen for dryness, hormone therapy if appropriate, counseling, or changes to medicines that affect arousal.
