Avanafil (brand name Stendra) is a fast-acting medicine for erectile dysfunction. Many men choose it because it can work in as little as 15–30 minutes and often lasts about 4–6 hours. If you want a drug that acts quickly before intimacy, avanafil is worth learning about.
How it works is simple: avanafil relaxes blood vessels in the penis so blood flow increases during sexual arousal. It belongs to the same group as sildenafil (Viagra) and tadalafil (Cialis) but tends to start faster than most. That makes it a good option when planning ahead is hard.
The usual doses are 50 mg, 100 mg, and 200 mg. Doctors often start with 100 mg and adjust up or down based on effect and side effects. Take it by mouth with or without food. For the quickest effect, avoid a heavy fatty meal right before taking it — food can slow absorption. Do not take more than one dose in 24 hours.
Timing matters. If you need fast action, take avanafil 15–30 minutes before sex. If you find the effect is too weak, talk to your doctor about adjusting the dose. If you take nitrates for chest pain, do not use avanafil — mixing them can cause a dangerous drop in blood pressure.
Common side effects include headache, flushing, nasal congestion, and back pain. Most are mild and go away on their own. Serious but rare issues include sudden vision loss or an erection that lasts more than four hours (priapism). Seek medical help right away for either of those.
Avoid avanafil if you use nitrates or strong CYP3A4 inhibitors like ritonavir or ketoconazole. Tell your doctor about blood pressure meds, alpha-blockers, and supplements. Alcohol and grapefruit juice can change how the drug works, so ask your prescriber what’s safe for you.

Talk to your doctor about other medicines you take and any heart issues. Older adults may need lower doses. Avoid using avanafil to boost confidence — using ED drugs without need can mask other problems. Ask your prescriber about costs, coupons, or generic options if price is a concern. Keep a list of your medicines and show it during any online or in-person consult so the prescriber can pick safe choice today.
