Avanafil (brand name Stendra) is a prescription pill for erectile dysfunction that can start working in as little as 15 minutes. It’s part of the PDE5 inhibitor family, like sildenafil and tadalafil, but many men choose it for quicker onset and shorter active time. You need sexual stimulation; it won’t cause an erection by itself.
The drug works by blocking the PDE5 enzyme to increase blood flow to the penis during arousal. Standard dosing starts at 100 mg taken about 15–30 minutes before sex; doctors may adjust to 50 mg or 200 mg based on response and side effects. Don’t take more than one dose daily.
For fastest effect, take avanafil on an empty stomach — a large fatty meal can delay absorption. Avoid nitrates and nitroglycerin products at all costs: combining them with avanafil can cause a dangerous drop in blood pressure. If you take alpha-blockers for prostate issues, your doctor needs to time doses carefully to prevent dizziness or fainting. Tell your provider about heart disease, stroke history, low blood pressure, or retinal disorders before starting.
Avanafil is metabolized by CYP3A4. Strong inhibitors like ketoconazole, itraconazole, and ritonavir raise avanafil levels and increase side effects; your prescriber may lower your dose or choose another treatment. Grapefruit juice may also affect metabolism, so avoid large amounts with this medication. People with serious liver or kidney problems often need lower doses and closer monitoring.
Common side effects include headache, flushing, nasal congestion, and back pain. Most are mild and short-lived. A rare but serious problem is priapism — an erection lasting more than four hours. If that happens, get emergency care to avoid permanent damage. Stop the drug and seek help if you experience sudden vision loss or chest pain.
Compared with sildenafil (Viagra) and vardenafil (Levitra), avanafil tends to act faster and may cause fewer lingering effects. Tadalafil (Cialis) lasts much longer — up to 36 hours — so it fits different needs. Effectiveness across PDE5 drugs is similar for many men, but side effect profiles and timing vary. If one drug doesn’t work or causes bad side effects, trying a different prescription often helps.
Buying avanafil requires a valid prescription. If you order online, use accredited pharmacies, check for a visible license, and read reviews. Telehealth services can provide legitimate prescriptions after an online consult. Avoid sites that sell without a prescription or offer very low prices — counterfeit pills can be dangerous. Look for pharmacy discount programs, manufacturer coupons, or insurance coverage to cut costs.
Quick practical tips: start with a lower dose to test tolerance, avoid heavy alcohol the night you plan to use it, and track how long it takes to work and any side effects so you can discuss them with your doctor. If you have ongoing heart symptoms or repeated side effects, stop the medication and call your provider — there’s always another option to explore.
