Common use

Stendra (avanafil) is the newest ED drug approved for the treatment of erectile dysfunction in adult men. As a second-generation PDE5 inhibitor, avanafil offers a significant advantage over older medications in its class: it works faster, often producing results in as little as 15 minutes after ingestion. When you buy Stendra online, you are choosing a modern, highly selective phosphodiesterase type 5 inhibitor that targets penile blood vessels with greater precision than earlier ED treatments, resulting in fewer systemic side effects. Stendra is marketed in the US under the brand name Stendra and is also available as an affordable Stendra generic. Whether you are dealing with occasional difficulties or chronic erectile dysfunction, avanafil provides a fast-acting ED solution that fits seamlessly into spontaneous intimate moments without the need for extensive advance planning.



Dosage and direction

The recommended starting dose of Stendra is one 100 mg tablet taken orally approximately 15 to 30 minutes before planned sexual activity. However, your doctor may adjust the dosage — prescribing 50 mg or 200 mg — depending on your individual response, tolerability, and medical profile. Always aim for the minimum effective dose to reduce the risk of side effects. Do not take Stendra more than once per day. The medication can be taken with or without food, though a very high-fat meal may slightly delay its onset. Limit alcohol consumption while using avanafil, as excessive drinking can impair erectile function and increase the risk of dizziness or low blood pressure. If you buy avanafil and find that the standard dose does not produce the desired results, consult your doctor before making any changes.



Precautions

You should consult your doctor before using Stendra to treat your erectile dysfunction. It is essential that your physician evaluate your cardiovascular health, because sexual activity itself places demands on the heart. Inform your doctor if you have: heart disease, angina, or a history of heart attack or stroke; high or low blood pressure; liver or kidney disease; retinitis pigmentosa or other visual disorders; a bleeding disorder; a physical deformity of the penis; sickle-cell disease, leukemia, or multiple myeloma; or any condition that predisposes you to priapism. Also disclose all medications you take, as many drugs interact with avanafil. Stendra is for adult male use only and should not be taken by women or children. Avoid driving or operating machinery until you understand how this fast-acting ED medication affects you personally.



Contraindications

Stendra (avanafil) must not be taken together with any form of organic nitrates, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and recreational "poppers" containing amyl nitrite. The combined vasodilatory effect creates an increased risk of severe, potentially life-threatening hypotension. Nitrates can be taken no earlier than 12 hours after the use of Stendra. Any known hypersensitivity to avanafil or any of the inactive ingredients in the formulation is also a strict contraindication. Patients with unstable angina, severe hepatic impairment, end-stage renal disease on dialysis, or recent cardiovascular events should not use this product without specialist approval.



Possible side effects

The most common adverse effects of Stendra include headache (reported by approximately 5% of users) and facial flushing (up to 4% of users). Other possible side effects include nasal congestion, back pain, and mild gastrointestinal issues such as indigestion or nausea. Most of these negative effects are dose-dependent and can often be minimized by adjusting the dosage under medical supervision. Seek immediate medical attention if you experience: sudden loss of vision in one or both eyes; sudden decrease or loss of hearing; an erection that is painful or lasts more than 4 hours (priapism); chest pain, dizziness, or fainting; severe skin rash or allergic reaction; or irregular heartbeat. Though rare, these serious effects require prompt treatment.



Drug interaction

Stendra should not be taken concurrently with organic nitrates, as the interaction can cause severe hypotension. Additionally, exercise caution when combining avanafil with: alpha-blockers used for high blood pressure or prostate enlargement; antihypertensive medications; strong CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, atazanavir, clarithromycin, and nelfinavir; moderate CYP3A4 inhibitors like erythromycin, fluconazole, and diltiazem; and other PDE5 inhibitors. Alcohol consumption should be limited, as it may potentiate the blood-pressure-lowering effects of avanafil. Before you buy Stendra online, provide your doctor with a complete list of all prescription medications, over-the-counter drugs, vitamins, and herbal supplements you are currently taking.



Missed dose

There is no negative therapeutic effect observed in patients who miss a dose of Stendra. The drug is not addictive and is used on an as-needed basis before sexual activity. It does not require a regular dosing schedule. Simply take one tablet when you anticipate sexual activity, respecting the once-daily maximum.



Overdose

Do not exceed the recommended dose of Stendra. Overdose of avanafil can intensify its side effects, potentially causing severe dizziness, drowsiness, prolonged painful erection, dangerous hypotension, visual disturbances, and fatigue. If you experience flushing, persistent headache, back pain, or any symptoms suggestive of overdose, immediately contact a medical care specialist or go to the nearest emergency department for evaluation and treatment.



Storage

Keep Stendra in a dry, dark place out of reach of children at room temperature between 20 and 25 degrees C (68 and 77 degrees F). Protect from moisture and direct light. Do not use tablets past the expiration date printed on the packaging.
