Avanafil (Stendra): Fast-acting ED medicine you should know

Avanafil is one of the newer pills for erectile dysfunction (ED). People pick it because it often works faster than older options. If you want an ED medicine that can kick in quickly and can be taken when needed, avanafil is worth knowing about.

How avanafil works and how to take it

Avanafil belongs to a group called PDE5 inhibitors. It relaxes blood vessels in the penis so blood flows easier during sexual arousal. Most men notice effects in about 15–30 minutes, and the effect can last up to six hours. That doesn’t mean constant erections for six hours — it means you have a window to be ready for sex.

Common doses are 50 mg, 100 mg, and 200 mg. Doctors often start at 100 mg and adjust up or down based on how you respond and side effects. Take it shortly before sex. Fatty meals can slow how fast it works, so avoid a heavy, greasy meal if you want the quickest start.

Safety tips, side effects, and interactions

Side effects are usually mild: headache, flushing, nasal congestion, back pain, or dizziness. If you get an erection lasting more than 4 hours, get emergency care—this is called priapism and needs quick treatment to avoid damage.

Don’t take avanafil with nitrates (used for chest pain). That combo can drop your blood pressure dangerously. Also be careful with strong CYP3A4 inhibitors like ritonavir or some antifungals — they can raise avanafil levels. Talk to your doctor about other meds you take, including alpha-blockers for prostate or blood pressure, and avoid mixing with recreational poppers.

If you have serious heart problems, unstable angina, recent stroke, or uncontrolled high blood pressure, your provider may say it’s not safe. Always check with a clinician before starting any ED drug.

Alcohol in large amounts can reduce effectiveness and increase dizziness. Grapefruit juice may raise avanafil levels, so avoid large amounts around the time you take the pill.

Storage is simple: keep at room temperature, away from moisture and heat. Keep out of reach of children.

Buying tips: avanafil needs a prescription in most countries. Use a licensed pharmacy—local or reputable online stores. If you see offers for very cheap pills without a prescription, be cautious. Fake ED drugs are common and can be unsafe.

Want to try avanafil? Start the conversation with your doctor. Be honest about heart health, other meds, and how often you expect to use it. That helps pick the right dose and keeps you safer.

Short, practical takeaway: avanafil can act fast and give you a useful window for sex, but check meds and heart health with your doctor, start at a low dose if suggested, and buy only from trusted pharmacies.
