If you’ve heard of Viagra, you’ve probably heard the name sildenafil too. It’s the same active ingredient, just sold without the brand label and usually at a lower price. People take it to treat erectile dysfunction (ED), which means having trouble getting or keeping an erection firm enough for sex.
Because it’s a prescription drug, you shouldn’t just grab any tablet off the shelf. Knowing how it works, the right dose, and what to watch out for can keep you safe and get the results you want.
Sildenafil belongs to a group called PDE5 inhibitors. In simple terms, it blocks an enzyme that narrows blood vessels in the penis. When the enzyme is blocked, blood vessels stay relaxed, blood flow improves, and an erection can happen when you’re sexually aroused.
The medicine only works with sexual stimulation. It doesn’t cause an erection on its own, and it won’t keep you stiff for hours. Most men feel the effect within 30 to 60 minutes, and the peak effect lasts about two to four hours. If you take it with a heavy meal, especially something fatty, the start can be a bit slower.
Typical starting doses are 25 mg or 50 mg, taken about an hour before sex. If that works well, doctors may raise the dose to 100 mg. Never take more than one dose in a 24‑hour period. If you miss a dose, just skip it; don’t double up.
Buying generic sildenafil online can save money, but you have to be careful. Look for pharmacies that require a prescription and show a pharmacist’s contact info. Legit sites will usually have a physical address and a clear privacy policy.
Check the price – if it’s dramatically lower than other reputable stores, it might be a red flag. Cheap “online pharmacies” often sell counterfeit pills that contain wrong ingredients or no active drug at all.
Read reviews and see if the site is accredited by a recognized pharmacy board. When you place an order, you should get a confirmation email with the medication name, dosage, and instructions. If anything feels off, pause and verify before taking the pills.
Finally, keep your prescription up to date. If you’re unsure about dosage or have health conditions like heart disease, low blood pressure, or are on nitrates, talk to your doctor first. Mixing sildenafil with certain meds can cause serious problems.In short, Sildenafil generic works the same as the brand version, offers a cost‑effective way to treat ED, and is safe when taken correctly. By choosing a reputable online pharmacy and following dosage guidelines, you can enjoy the benefits without the hassle.
