Viagra (sildenafil) is a pill that helps men get and keep an erection long enough for sex. It isn’t a hormone, it just relaxes blood vessels in the penis so more blood can flow in when you’re aroused. The effect starts in about 30 minutes and can last up to four hours. If you’re new to it, this guide breaks down the basics you need to know.
When you’re sexually stimulated, your body releases a chemical called nitric oxide. This triggers a chain reaction that makes a molecule called cGMP widen the arteries in the penis. Viagra blocks an enzyme (PDE5) that breaks down cGMP, so the vessels stay open longer. The result is a firmer, longer-lasting erection. It won’t work without sexual excitement, so you still need the right mood and foreplay.
Buying Viagra online can be cheap, but you have to watch out for fake pills. Look for pharmacies that require a prescription, show a physical address, and have a pharmacist’s contact info. Check for a seal from a recognized regulator (e.g., TGA in Australia, FDA in the US). Avoid sites that sell “Viagra without a prescription” at rock‑bottom prices – they’re usually counterfeit.
Typical dosage for most men is 50 mg taken about an hour before sex. If that’s too strong or not strong enough, doctors often adjust to 25 mg or 100 mg. You shouldn’t take more than one pill in 24 hours. Food, especially high‑fat meals, can slow down how fast the drug works, so try to take it on an empty stomach for the quickest effect.
Common side effects include headache, flushing, upset stomach, and a mild visual change (like a blue tint). These usually fade in a few hours. Rare but serious reactions are sudden vision loss or an erection lasting longer than four hours (priapism). If either happens, get medical help right away.
Before you start, tell your doctor if you have heart disease, low blood pressure, or are taking nitrates (often prescribed for chest pain). Mixing Viagra with nitrates can cause a dangerous drop in blood pressure. Also, limit alcohol – too much can reduce the drug’s effectiveness and increase side effects.When the prescription arrives, store the tablets in a cool, dry place and keep them out of reach of children. Don’t share your pills with anyone else, even if they have similar symptoms. If you miss a dose, just wait for the next opportunity; don’t double up.
In short, Viagra works by keeping blood flow steady in the penis, and it can be a reliable tool when used correctly. Follow dosage instructions, watch for side effects, and only buy from reputable online pharmacies that ask for a prescription. Doing so gives you the best chance of a safe, effective experience.
