The original on-demand ED medication — taken 30–60 minutes before intimacy to support firmer, longer-lasting erections. Well-studied, well-tolerated for most men. Cardiovascular screening included in your intake. ## What to expect - Taken as needed — This is an on-demand tablet rather than a daily medication. - Timing matters — Take it 30 to 60 minutes ahead, and avoid a heavy meal beforehand. - Arousal still required — It supports the response rather than replacing desire. - Dose can be adjusted — If the effect is too strong or not enough, your clinician can change it. ### Your treatment Oral tablets Your prescription confirms the strength, quantity and dispensing schedule. ### Your routine Taken before intimacy, as prescribed.

How long before it works, and how long does it last? Sildenafil typically takes effect within 30 to 60 minutes and lasts around four to six hours. A heavy or high-fat meal beforehand can delay onset. Do I need arousal for it to work? Yes. Sildenafil improves blood flow in response to arousal — it does not create desire on its own. What are the common side effects? Headache, facial flushing, nasal congestion and indigestion are the most frequently reported, and are usually mild. What should I avoid taking with it? Nitrates in any form are a hard contraindication — the combination can cause a dangerous drop in blood pressure. Tell your clinician about all medications, including anything for chest pain or blood pressure. When should I seek urgent care? An erection lasting more than four hours needs immediate medical attention. Sudden vision or hearing changes also warrant stopping and seeking care. ## Start your plan today 90-day supply · $209 every 90 days [Start assessment](https://www.vitalsvault.com/checkout/medications/app?plan=69661321-4b77-23df-f40a-95c8d56ddcec&gender=male&flow=payment-first&skipWelcome=true&source=treatments) ## The clinicians behind your care Your treatment is reviewed and prescribed by US-licensed clinicians in our network. ![Diana Kumar, MD, FACOG](https://static.vitalsvault.com/treatments/editorial/diana-kumar-md-c56d4b361d5774a7.webp) ### Diana Kumar, MD, FACOG Women's hormone health Board certified in obstetrics and gynecology and a Menopause Society Certified Practitioner.
