Sildenafil – What It Is and How It Works

If you’ve ever Googled “ED pills,” chances are you saw the name sildenafil pop up. In simple terms, it’s a medicine that helps men get and keep an erection by relaxing blood vessels in the penis. The active ingredient was first sold under the brand name Viagra, but many generic versions exist today.

When you take sildenafil, it blocks an enzyme called PDE5. Blocking this enzyme lets more blood flow into the penile tissue during sexual arousal. It doesn’t create an erection on its own – you still need stimulation. Think of it as a traffic cop that lifts a roadblock so blood can move freely.

How to Take Sildenafil Safely

The usual starting dose for most men is 50 mg, taken about an hour before intimacy. Some doctors start lower (25 mg) if you’re new to the drug or have health concerns, while others may increase to 100 mg after a few tries.

Swallow the tablet whole with water; don’t crush it. Food can slow absorption, especially heavy meals, so try to take it on an empty stomach for faster results. If you’re on nitrate medication (often prescribed for chest pain), avoid sildenafil completely – the combo can cause a dangerous drop in blood pressure.

Possible Side Effects & When to Seek Help

Most men feel fine, but common side effects include headache, flushing, upset stomach, and occasional visual changes like a blue tint. These usually fade within a few hours. If you notice a painful or prolonged erection lasting more than four hours (priapism), get medical help right away – it can damage tissue.

Other red flags are sudden chest pain, severe dizziness, or an allergic reaction with swelling and breathing trouble. Those signs mean you need emergency care.

Because sildenafil affects blood flow, men with serious heart conditions should talk to a doctor before trying it. The same goes for anyone taking blood thinners, certain antidepressants, or high‑dose alpha blockers.

If you’re wondering where to get genuine sildenafil online, look for licensed pharmacies that require a prescription, show clear contact info, and have verified reviews. Avoid sites that sell the drug without asking for a doctor’s note – they often deal in counterfeit pills.
