Stendra (Avanafil)

An as-needed erection medicine, with a prescription tailored to your health.

Written by

Medically reviewed by Dr. Ather Malik, DO

Stendra contains avanafil, a prescription treatment for erectile dysfunction. It helps the erection response during sexual stimulation and is taken before sex. At the prescribed 100 mg or 200 mg dose, it can be used as early as approximately 15 minutes beforehand.

At AV Community Clinic, we assess erection difficulties and discuss whether avanafil is suitable for you. Our care includes prescribing, help arranging your medication purchase through a participating pharmacy and follow-up. We review safety and practical fit before recommending a change from another erection treatment.

Do not combine avanafil with nitrates, recreational nitrites, riociguat or strong CYP3A4 inhibitors. A shorter time to possible effect does not remove the need to check medicine interactions.

What Stendra does

Avanafil is a PDE5 inhibitor. During arousal, it supports relaxation of blood vessels in the penis, helping increase blood flow and maintain an erection. It does not cause an automatic erection simply because you have swallowed a tablet.

Stendra treats erectile dysfunction in adult men. It is not a treatment for low desire and does not prevent pregnancy or sexually transmitted infections. If the main problem is discomfort, ejaculation timing or lack of interest in sex, we assess that rather than assume an erection medicine will resolve it.

Some patients ask about Stendra because they want less planning before sex. Others are considering a change after side effects or disappointing results with a different tablet. Tell us what you want to improve so the discussion starts with your experience rather than a brand preference alone.

What the faster onset means in practice

The prescribing instructions allow 100 mg or 200 mg to be taken as early as approximately 15 minutes before sex. The 50 mg dose is taken approximately 30 minutes beforehand. Your own instructions depend on the dose we prescribe.

These timings are not a guarantee that everyone will respond at the earliest minute. Stimulation, the circumstances of sex and individual response still matter. If a dose does not produce the result you hoped for, do not take another tablet that evening to try to speed things up.

We explain how to judge the response before deciding whether treatment needs to change. Tell us the dose, when you took it, whether there was any improvement and whether you felt unwell. That information helps us distinguish timing concerns from a poor fit or an underlying issue needing further care.

Your assessment at our clinic

We ask about the pattern of erection difficulty, how long it has been present and whether it varies with the situation. We also discuss other changes in sexual function. You can explain the problem in your own words, and you do not need to know which diagnosis or dose to request.

Your health review includes heart symptoms, blood pressure, kidney and liver conditions and the medicines you take. Erectile dysfunction can occur alongside other health problems. We may recommend an examination or tests when your history suggests they would help guide treatment.

Bring details of erection medicines you have already tried, including products obtained without a familiar prescription label. Tell us about side effects and any reason you stopped. We can assess a new treatment more reliably when we understand what happened with the previous one.

Choosing an avanafil strength

Stendra tablets come in 50 mg, 100 mg and 200 mg strengths. The usual starting dose is 100 mg, with changes based on effectiveness and tolerance. The aim is the lowest dose that provides a useful benefit within an appropriate safety plan.

A lower dose may be needed with certain medicines, while some combinations mean avanafil should not be used at all. The strongest tablet is not a suitable default. We check your complete medication list before deciding which strength, if any, is appropriate.

If you are changing from sildenafil, vardenafil or tadalafil, milligram strengths cannot be compared directly across the products. Do not use the number on your previous tablet to choose an avanafil dose. We provide specific instructions for the new medicine.

Stendra price and purchase

The listed Stendra offer starts at $62.00 for avanafil 100mg 4 tablets. The listed price covers medication only and doesn't include the cost of doctor visit. We confirm the prescribed product, strength, pack and final medication cost before you proceed.

We assess suitability before issuing a prescription. When treatment is appropriate, we coordinate dispensing through a participating pharmacy and explain how to use the supplied medicine. If you have a product preference, mention it before the prescription is finalized.

The cost of another strength or a different quantity can vary. We discuss those details alongside your treatment needs rather than encourage a higher dose to reduce the price per tablet. If supply is a problem, contact us so we can review an appropriate alternative.

Taking your tablets

Take only the prescribed dose before sexual activity and do not use avanafil more than once in 24 hours. It can be taken with or without food. Follow any more restrictive directions we give because of another medicine or your health.

This is an as-needed treatment, so there is no daily dose to catch up after a day without sex. Do not take an additional tablet because plans changed or the first attempt was unsuccessful. Ask us if you are unsure how the directions apply to your routine.

Keep tablets in their original packaging and check the strength when collecting a refill. Do not share the medicine. If the pharmacist changes the appearance or product, make sure you understand what has been dispensed and that the directions match your prescription.

Interactions that can change the prescription

Strong CYP3A4 inhibitors can greatly increase avanafil exposure and must not be combined with Stendra. Examples include some HIV treatments, azole antifungals and clarithromycin. Other medicines affecting this pathway can require a lower dose. We check exact drug names rather than broad categories alone.

Nitrates, recreational nitrites and riociguat must not be used with avanafil. Alpha-blockers and blood pressure medicines can also increase the risk of symptomatic low blood pressure. Tell us about occasional chest pain treatment, sprays, patches and recreational substances as well as daily tablets.

Tell your pharmacist and any other prescriber that you use avanafil, even if it is infrequent. Before starting a new medicine, check whether it changes your erection treatment. Taking the products a few hours apart does not automatically make an interacting combination safe.

Alcohol, dizziness and low blood pressure

Avanafil and alcohol can both lower blood pressure. Drinking a substantial amount increases the risk of dizziness, headache, a fast heartbeat or faintness. We discuss your usual alcohol intake so the advice fits the way you are likely to use the medicine.

Alcohol can also make erection difficulties worse. If the first attempt with Stendra happens after heavy drinking, the result may be difficult to interpret. Do not compensate by taking more medication or combining it with a different erection product.

If you become dizzy, sit or lie down in a safe place and avoid driving. Seek medical help if symptoms are severe, persist or include chest discomfort or loss of consciousness. Tell us about the episode before another dose so we can reconsider the plan.

Heart health and emergency symptoms

We consider whether sexual activity is appropriate for you before prescribing. Tell us about chest pain, recent heart attack or stroke, significant rhythm problems and breathlessness with ordinary activity. Do not use an erection tablet to push through symptoms that need assessment.

If chest pain occurs during sex, stop and seek emergency care. Do not take a nitrate yourself. Tell the treating team the exact time and dose of your last avanafil tablet so they can choose appropriate treatment.

The Stendra label describes nitrate consideration only in a life-threatening situation after at least 12 hours and with close medical supervision. That is not an instruction to resume your own nitrate after a countdown. The emergency clinician must assess the circumstances.

Side effects to discuss with us

Headache, flushing, nasal congestion and back pain can occur with avanafil. Tell us whether the symptoms appear after each dose and how much they interfere with your activities. A medicine can improve erections yet still be the wrong choice if its side effects are unacceptable.

Seek emergency care for an erection lasting more than four hours. Sudden loss or marked reduction of hearing or vision requires urgent medical attention too. Stop the medicine and do not take a different erection tablet while awaiting assessment.

We also want to know about less dramatic but repeated problems, such as feeling lightheaded whenever you stand after a dose. Describe the timing, other medicines and alcohol used that day. Do not make your own dose change until we have reviewed the reaction.

Considering another erection treatment

Avanafil, sildenafil, vardenafil and tadalafil share a broad treatment approach, but their dosing routines and interactions differ. A medicine that suits a friend may not suit your heart treatment, schedule or previous side effects. We compare the features that matter for you.

Do not overlap products or take one to rescue an unsuccessful dose of another. When a switch is appropriate, we explain when the previous medicine should stop and when the new one can start. The plan considers how long the earlier medicine remains active.

If oral treatment is unsuitable or consistently ineffective, we discuss further assessment and other options. That may include specialist care or a different type of treatment. There is no need to keep cycling through tablets without reviewing why the response is limited.

Reviewing treatment and renewing a prescription

At follow-up, we ask about erection quality, reliability, timing and any unwanted effects. Tell us whether the treatment has made sex easier or introduced another difficulty. We review the whole experience rather than judge success only by whether an erection occurred.

We reassess your medication list and any new symptoms before continuing treatment. Let us know about an operation, a new heart diagnosis or a change in kidney or liver health. An old prescription is not a substitute for checking a new interaction.

If another clinic prescribed Stendra, we can assess ongoing care. Share the product, strength and directions and tell us how it worked. We confirm the appropriate prescription and medication supply after reviewing those details with you.

Common questions

Can Stendra work in approximately 15 minutes?

At prescribed doses of 100 mg or 200 mg, the instructions allow use as early as approximately 15 minutes before sex. The 50 mg dose has different timing. Individual response varies, and sexual stimulation is still needed.

Is avanafil suitable if Viagra did not help?

Possibly, but a different brand is not automatically the solution. We review how you used the previous medicine, the response, side effects and your health. That helps decide whether avanafil or another approach is appropriate.

Can I take a higher dose on the same day?

Do not take an extra dose or increase the strength yourself. Avanafil is used no more than once in 24 hours, with any additional limits on your prescription. Contact us to review inadequate benefit.

Does Stendra have fewer interactions because it acts quickly?

No. Timing of onset does not remove interactions. Nitrates, riociguat and strong CYP3A4 inhibitors are particularly important. We need a complete list of your medicines and recreational substances before prescribing.

What does the listed starting price cover?

The listed offer is avanafil 100mg 4 tablets for medication only. Your doctor visit is separate. We confirm the prescribed product and final medication cost before purchase.

Can I use avanafil after taking tadalafil?

Do not combine or switch between them without a plan from your prescriber. Tadalafil can remain active for longer than other erection medicines. We consider your last dose and health before giving instructions.

Do I need to take it on an empty stomach?

Avanafil can be taken with or without food. Follow your prescription rather than adding extra rules from another erection medicine. Tell us if the timing or effect seems inconsistent so we can review your experience.

Can you review a prescription from another clinician?

Yes. We can assess continuing treatment using your prescription details, response and updated medical history. A review is particularly important if your health or other medicines have changed since the previous supply.
