How it operates step by step
The PDE5 enzyme is suppressed by sildenafil. This enhances the effect of nitric oxide in blood vessels, relaxing smooth muscle and increasing blood flow to genital tissues. The improved circulation can help with physical aspects of arousal in some women, such as swelling and sensitivity, though it does not reliably increase sexual desire for everyone. A clinician can help determine whether the a mechanism is appropriate for your specific symptoms.
Prescribed dose and directions
Sildenafil for sexual activity is generally taken by mouth with water. Food, especially fatty meals, may delay absorption and postpone the onset of effect.
- Route: Oral administration with water; avoid large meals at dosing time.
- Typical onset and duration: Effects often begin around 30 to 60 minutes after a dose and can last several hours.
- Common off-label approach: A single dose of 50 mg taken prior to sexual activity; clinicians may recommend 25 mg or 100 mg depending on response and tolerability.
- Maximum frequency: Do not take more than one dose within 24 hours unless advised otherwise by your prescriber.

- Effectiveness differs between individuals and by underlying cause; some research has looked at specific groups such as postmenopausal women or those with antidepressant-related sexual dysfunction with mixed results.
If you experience severe or worrying symptoms after taking sildenafil, seek urgent medical attention. See Potential adverse outcomes for more details.
