When you hear Sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor used primarily to treat erectile dysfunction and pulmonary arterial hypertension. Also known as Viagra, it's one of the most prescribed medications for sexual health in the world. But it’s not just a pill for performance—it’s a tool that changes blood flow, and understanding how it works can help you use it safely and effectively.
Sildenafil works by relaxing muscles in the walls of blood vessels, letting more blood flow into certain areas of the body. For most people, that means helping get and keep an erection when sexually stimulated. But it also helps people with pulmonary arterial hypertension by reducing pressure in the lungs. The same mechanism, different condition. It doesn’t work on its own—you still need sexual arousal. And it doesn’t make you last longer or boost desire. That’s a common myth. What it does is remove a physical barrier so your body can respond naturally.
People often confuse Sildenafil with other ED meds like tadalafil or vardenafil. They’re all PDE5 inhibitors, but they last different lengths of time, kick in at different speeds, and interact differently with food or alcohol. Sildenafil usually starts working in about 30 to 60 minutes and lasts around 4 to 5 hours. Taking it with a high-fat meal can delay its effect. And if you’re on nitrates for heart issues, you can’t take it—ever. That combination can drop your blood pressure to dangerous levels.
Side effects? Headaches, flushing, upset stomach, and nasal congestion are common. Most are mild and go away. But if you have sudden vision or hearing loss, chest pain, or an erection lasting more than four hours, get help immediately. These aren’t just inconveniences—they’re red flags.
