If you’ve heard the name sildenafil and wondered what it actually does, you’re in the right spot. It’s the active ingredient behind the brand name Viagra and is used to treat erectile dysfunction (ED). In plain terms, it helps blood flow to the penis so you can get and keep an erection when you’re sexually aroused.
Unlike some pills that work all the time, sildenafil only works when sexual stimulation is present. That means you won’t get an erection just by taking the tablet – you still need that natural trigger. Most men find it starts working within 30 to 60 minutes, and the effect can last up to four hours, giving you a flexible window for intimacy.
Standard dosing for most men is 50 mg taken about an hour before sex. If that feels too strong or causes side effects, doctors often recommend dropping to 25 mg. On the other hand, if 50 mg isn’t enough, the dose can be increased to 100 mg, but never go above that without a prescription.
Take the tablet with water, not with a heavy meal. Big, fatty meals can slow down absorption, making the pill feel less effective. Also, avoid alcohol in excess; a couple of drinks usually won’t hurt, but too much can diminish the result and raise the risk of a headache.
Common side effects include a mild headache, flushing, or an upset stomach. These usually pass within a few hours. If you notice a painful or prolonged erection lasting more than four hours, seek medical help right away – it can damage tissue.
Many people look for cheaper options than the brand name. Generic sildenafil is legally the same molecule, just sold under different names. To buy it safely, follow these steps:
When you’re confident the pharmacy is legit, add the appropriate strength (25 mg, 50 mg, or 100 mg) to your cart, provide your prescription, and place the order. Most reputable sites ship within 3‑5 days with discreet packaging.
Finally, keep a copy of your prescription handy. Some countries require you to show it at the point of delivery, and it’s useful if you need to discuss dosage changes with your doctor later.
In short, sildenafil works well for many men with ED, but it’s important to follow dosing guidelines, watch for side effects, and only purchase from trusted online pharmacies. With the right approach, you can enjoy the benefits without breaking the bank or risking your health.
