Avanafil (Stendra): Fast-Acting ED Medicine — What You Need to Know

Need a straightforward take on avanafil? This drug — sold commonly as Stendra — treats erectile dysfunction and is known for a quick start. Many men notice effect in 15–30 minutes and it can last up to about six hours. Below I’ll cover how it’s used, common doses, side effects to watch for, and simple steps to buy it safely online.

How avanafil works and dosing basics

Avanafil relaxes blood vessels in the penis to help achieve and keep an erection when you’re sexually aroused. It does not cause arousal by itself. Typical dosing: 50 mg, 100 mg, or 200 mg taken as needed about 15–30 minutes before sex. Doctors often start at 100 mg and adjust based on effect and side effects. Don’t take more than one dose in 24 hours.

Tips on timing: take it on an empty stomach for faster action. A heavy, fatty meal can slow how quickly it works. Avoid mixing large amounts of alcohol — that can reduce effectiveness and raise side effect risk.

Side effects, warnings, and interactions

Common side effects are headache, flushing, nasal congestion, back pain, and dizziness. Serious issues are rare but include sudden vision problems, hearing loss, or an erection lasting more than 4 hours (priapism). If any of those happen, get emergency care right away.

Major drug interactions: never use avanafil with nitrates (often prescribed for chest pain) — the combo can dangerously drop blood pressure. Also be careful with alpha-blockers for prostate or blood pressure, and with strong CYP3A4 inhibitors (like certain antifungals and HIV drugs) — these can raise avanafil levels and require dose changes. Grapefruit and grapefruit juice can affect metabolism too; avoid large amounts while taking avanafil.

If you have heart disease, unstable angina, severe liver problems, or very low blood pressure, talk with your doctor before using avanafil.

Always follow your prescriber’s guidance and tell them about all medicines and supplements you use.

Buying online? Here are quick, practical safety checks:

• Only buy from pharmacies that require a prescription and show clear contact info and pharmacy licensing.
• Look for secure checkout (https), a pharmacist you can contact, and normal market prices — ultra-cheap offers are often risky.
• Check packaging and expiry when your order arrives. If pills look different from usual, don’t use them and contact the seller.
• Prefer pharmacies with transparent return and privacy policies and readable user reviews.
