Get sildenafil prescribed discreetly by a licensed physician. The same active ingredient as Viagra® — at a fraction of the cost. No waiting room, no awkward conversations.
Sildenafil is the FDA-approved, generic version of Viagra — the world's most prescribed erectile dysfunction medication. Here's how it works.
Sildenafil works by inhibiting the PDE5 enzyme, which relaxes smooth muscle tissue in the penis and increases blood flow — enabling a natural erectile response to sexual stimulation.
Sildenafil contains the exact same active ingredient as Viagra®. FDA-approved since 1998, it has been used safely by tens of millions of men worldwide with an extensive clinical track record.
Most men experience effects within 30–60 minutes of taking sildenafil. Effects last 4–6 hours, giving you a natural, on-demand window for sexual activity without planning your whole day around it.
In clinical trials, sildenafil improved erectile function in over 80% of men with ED — regardless of age or severity. It remains one of the most studied and trusted medications in men's health.
Both are FDA-approved PDE5 inhibitors that effectively treat erectile dysfunction. The difference lies in how long they work and how you take them.

Everything you need to know about sildenafil, dosing, safety, and getting a prescription online.
Yes. Sildenafil is the generic version of Viagra and contains the exact same active ingredient — sildenafil citrate. Generic sildenafil is FDA-approved, equally effective, and typically costs significantly less than brand-name Viagra. The only real difference is the name on the bottle and the price you pay.
Sildenafil typically begins working within 30 to 60 minutes of taking it. Effects can last 4 to 6 hours. For best results, take it on an empty stomach or after a light meal, as heavy or high-fat meals may delay absorption and reduce effectiveness.
Sildenafil comes in 25mg, 50mg, and 100mg doses. Most men start at 50mg. Your Truventa physician will evaluate your health history, other medications, and symptoms to prescribe the dose that's safest and most effective for you. Never adjust your dosage without speaking to a physician first.
Moderate alcohol consumption (1–2 drinks) is generally considered acceptable with sildenafil, but excessive alcohol can impair your ability to get an erection and may increase side effects such as dizziness or low blood pressure. For best results and safety, it's advisable to limit alcohol when using sildenafil.
Common side effects include headache, flushing, nasal congestion, indigestion, and mild visual changes (such as a slight blue tinge to vision). These are usually mild and temporary. Serious side effects are rare but can include sudden vision or hearing loss, chest pain, or a prolonged erection (priapism — lasting more than 4 hours). Seek emergency medical care immediately if any serious side effects occur. Always inform your physician of all medications you take, especially nitrates.
Yes, sildenafil is a prescription medication in the United States. However, getting a prescription is easy and convenient through Truventa Medical. Simply complete a free online health intake (about 5 minutes), and a licensed physician will review your information and issue a prescription if medically appropriate — all without visiting a clinic or waiting room.
