Sildenafil Citrate: What It Is, How It Works, and What You Need to Know

When you hear Sildenafil Citrate, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction and pulmonary arterial hypertension. Also known as the active ingredient in Viagra, it works by relaxing blood vessels to increase blood flow—specifically to the penis during sexual stimulation. It’s not an aphrodisiac. It doesn’t create desire. It simply helps your body respond when you’re already turned on.

Sildenafil Citrate is part of a broader group of drugs called PDE5 inhibitors, which also includes Vardenafil, the active ingredient in Levitra and Levitra Jelly, Tadalafil, found in Cialis, and Avanafil, the fast-acting option in Stendra. These all do the same basic job but vary in how fast they kick in, how long they last, and how they interact with food or alcohol. Sildenafil usually starts working in 30 to 60 minutes and lasts about 4 to 5 hours. Take it on an empty stomach for the fastest effect—fatty meals can delay it by hours.

People use Sildenafil Citrate for more than just erectile dysfunction. It’s also prescribed for pulmonary arterial hypertension, where it helps reduce pressure in the lungs. But most searches around it come from men looking for ED solutions. And that’s where confusion sets in. Is it the same as Viagra? Yes, because Viagra is just the brand name for Sildenafil Citrate. Is it better than Cialis? Not necessarily—it just works faster but doesn’t last as long. Is it safe with heart meds? Not always. If you’re on nitrates for chest pain, mixing them with Sildenafil can drop your blood pressure to dangerous levels. That’s why doctors ask about your full medication list before prescribing it.

Side effects are usually mild—headache, flushing, upset stomach, or stuffy nose. But if you get sudden vision or hearing loss, stop taking it and get help right away. And don’t buy it from random websites. Counterfeit versions are everywhere, some containing nothing, others packed with dangerous fillers. Always get it through a licensed pharmacy with a prescription.

What you’ll find below are real comparisons: how Sildenafil stacks up against other ED pills, what alternatives like Vigora or generic versions actually offer, and how lifestyle factors like caffeine, alcohol, or even antidepressants can change how it works for you. No fluff. No marketing. Just what you need to know before you take it—or decide not to.
