I took it about half an hour before dinner plans. The first time I had eaten too much and it felt slow, but the next attempts were more predictable. I had a mild blocked nose and warmth in my face.

Active ingredient
Avanafil
Avana is an oral tablet containing avanafil for erectile dysfunction in adult men. It is intended for men who have difficulty achieving or maintaining an erection sufficient for sexual activity, and it supports penile blood flow during sexual stimulation.
Description
Avana contains avanafil, a phosphodiesterase type 5 inhibitor, also called a PDE5 inhibitor. PDE5 is an enzyme that breaks down cyclic guanosine monophosphate, or cGMP, the chemical messenger that relaxes penile blood vessels during arousal.
Composition
Avana contains avanafil, a phosphodiesterase type 5 inhibitor, also called a PDE5 inhibitor. PDE5 is an enzyme that breaks down cyclic guanosine monophosphate, or cGMP, the chemical messenger that relaxes penile blood vessels during arousal. By slowing cGMP breakdown, avanafil helps the smooth muscle in penile blood vessels relax and allows increased blood flow.
Sexual stimulation remains necessary. Avana does not create sexual desire and does not cause an erection in the absence of arousal.
The European Medicines Agency lists avanafil as a PDE5 inhibitor for erectile dysfunction, with treatment intended for adult men able to engage in sexual activity [1]. Erectile dysfunction can have vascular, metabolic, neurological, hormonal, psychological, or medication-related causes. Diabetes, high blood pressure, smoking, pelvic surgery, depression, and low testosterone may all contribute.
Practical tip: an erection that starts after taking Avana still depends on stimulation. A tablet taken without planned sexual activity will not produce a spontaneous erection.
Dosage and usage
Take Avana by mouth with water before anticipated sexual activity. It may be taken with or without food. The dose is stated on the pack — follow the leaflet.
The dose is stated on the pack — follow the leaflet.
Do not exceed one dose daily.
Use these principles:
- Take only the prescribed strength.
- Do not take a second tablet because the first one seems slow.
- Avoid combining Avana with another PDE5 inhibitor.
- Swallow the tablet whole with water.
- Keep alcohol intake modest, since alcohol can worsen dizziness, flushing, and erection difficulties.
- If a dose is not used for sexual activity, do not make it up later. Avana is taken when needed, not on a fixed daily schedule.
Practical tip: splitting a tablet to create a lower dose is not a substitute for a prescribed lower-strength tablet. Uneven pieces can lead to inconsistent dosing.
How it works
Avanafil inhibits PDE5, increasing penile blood flow during sexual stimulation. By slowing cGMP breakdown, avanafil helps the smooth muscle in penile blood vessels relax and allows increased blood flow.
Indications
Avana is an oral tablet containing avanafil for erectile dysfunction in adult men. It is intended for men who have difficulty achieving or maintaining an erection sufficient for sexual activity.
Comparison
PDE5 inhibitors share the same core goal: enhancing the natural erectile response to arousal by improving penile blood flow. Their onset and duration differ, so the best choice often depends on timing preferences, side-effect tolerance, and interacting medicines.
| Active ingredient | Typical timing profile | Practical distinction |
|---|---|---|
| Avanafil | May begin working from about 15–30 minutes | Often chosen for faster on-demand timing |
| Sildenafil | Usually taken about 30–60 minutes beforehand | Food, especially fatty meals, can delay onset |
| Tadalafil | Usually begins within 30–60 minutes and can last longer | Offers a longer window and may be prescribed daily at lower doses |
Avanafil may suit men who prefer a shorter planning window. Sildenafil has extensive clinical experience and remains widely used. Tadalafil creates a longer opportunity for sexual activity, though its prolonged effect may be less desirable for men who prefer a shorter treatment window.
All three can cause headache, flushing, nasal congestion, indigestion, and dizziness. None should be combined with nitrates. Switching between PDE5 inhibitors should be planned by the prescriber, not done by alternating tablets from one occasion to the next.
Contraindications
- Nitrate treatment for angina or heart disease.
- Use of riociguat for pulmonary hypertension.
- A recent heart attack, stroke, or unstable angina.
- Severe heart failure or blood pressure that is not controlled.
- Severe liver impairment.
- Severe kidney impairment requiring dialysis.
- Previous non-arteritic anterior ischaemic optic neuropathy, a serious form of sudden vision loss.
- Known allergy to avanafil or a tablet ingredient.
- A medical reason to avoid sexual activity because of cardiovascular risk.
Alpha-blockers used for prostate symptoms or blood pressure can also lower blood pressure. The combination may be possible under careful medical direction, though dose timing and dose selection matter. Strong CYP3A4 inhibitors, including ketoconazole, itraconazole, ritonavir, and clarithromycin, can raise avanafil levels and increase side-effect risk.
Grapefruit can alter exposure.
When this is not for you
This is not for you if you use nitrates for chest pain or recreational nitrite products, because combining avanafil with nitrates can cause a dangerous fall in blood pressure. You should also avoid Avana if you use riociguat, have recently had a heart attack or stroke, have unstable heart disease, severe liver or kidney problems, a history of sudden vision loss, or an allergy to avanafil or one of the tablet ingredients. If sexual activity is medically unsafe because of your cardiovascular condition, Avana is not suitable without medical assessment.
Side effects
Most side effects from avanafil are mild and temporary. Headache is among the most frequently reported effects. Flushing, nasal congestion, back pain, indigestion, and dizziness can also occur because PDE5 inhibition affects blood vessels beyond the penis.
Common effects may include:
- Headache
- Facial flushing or warmth
- Stuffy or runny nose
- Indigestion or acid reflux
- Back pain
- Dizziness
- Tiredness
Less common effects include palpitations, faster heartbeat, blurred vision, raised liver enzymes, or changes in blood pressure. Alcohol can make dizziness and low blood pressure more likely. Men taking blood pressure medicines may still use avanafil in some circumstances, though the treatment plan needs individual review.
Urgent medical help is required for chest pain, fainting, sudden loss of vision, sudden hearing reduction, or an erection lasting more than four hours. A prolonged erection, called priapism, can damage penile tissue if treatment is delayed. The FDA prescribing information for avanafil describes these serious reactions as uncommon but clinically significant warnings [2].
Practical tip: nasal congestion and facial warmth often settle as the medicine wears off. A severe headache with faintness, chest symptoms, or visual loss is different and needs urgent assessment.
Common mistakes
The most frequent mistake is taking more than one dose in 24 hours after a disappointing first attempt. Higher exposure does not guarantee a better erection and may increase headache, flushing, dizziness, or low blood pressure.
Another mistake is combining Avana with sildenafil, tadalafil, or erectile dysfunction products of uncertain composition. PDE5 inhibitors should not be stacked. Their blood-pressure effects can add up.
Some men also mistake alcohol-related erection difficulty for treatment failure. Alcohol can reduce sexual performance on its own, even where avanafil is present in the bloodstream. Others stop after one attempt, despite needing a few separate occasions to understand timing and response.
A final concern is ignoring cardiovascular symptoms. Erectile dysfunction can precede a diagnosis of high blood pressure, diabetes, or coronary artery disease. New erectile dysfunction with exertional chest discomfort, breathlessness, or reduced exercise tolerance deserves medical assessment before sexual activity is increased.
What doctors say
In clinical practice, prescribers usually assess erectile dysfunction as more than a bedroom concern. They ask about morning erections, libido, diabetes, blood pressure, cholesterol, sleep, smoking, mood, pelvic surgery, and medicines such as antidepressants or beta-blockers. That conversation helps separate a circulation problem from a hormonal, neurological, psychological, or mixed cause.
Doctors often explain that the first use is not a perfect test. The tablet needs adequate time, stimulation, and a reasonably relaxed setting. Some men take it after a large meal, drink heavily, become anxious, then assume the medicine failed. Adjusting timing or dose can make a meaningful difference.
WHO guidance on sexual health recognises that sexual function is linked with physical health, mental wellbeing, relationships, and chronic disease management [3]. Avana can support erectile function, yet improving blood pressure control, sleep, exercise capacity, diabetes management, and smoking cessation may improve the underlying vascular environment as well.
Frequently asked questions
Can Avana be taken with alcohol?
Small amounts of alcohol may not prevent avanafil from working, yet alcohol can worsen dizziness, flushing, fast heartbeat, and low blood pressure. Larger amounts can independently reduce erection quality and make the tablet seem less effective. FDA prescribing information from 2022 warns about additive blood-pressure effects when avanafil is used with substantial alcohol intake . Limiting alcohol is the more predictable approach.
Does Avana increase sexual desire?
Avana improves the blood-flow response involved in an erection, but it does not raise libido or testosterone. Desire can be reduced by stress, depression, relationship difficulties, low testosterone, chronic pain, poor sleep, or certain medicines. The EMA's 2024 product information describes avanafil as a treatment for erectile dysfunction rather than a hormonal treatment . A persistent loss of desire needs a different clinical assessment.
Can men with diabetes use Avana?
Men with diabetes can experience erectile dysfunction because long-term high glucose can affect blood vessels and nerves. PDE5 inhibitors are commonly considered for suitable men with diabetes, provided cardiovascular status and other medicines are reviewed. The European Association of Urology’s 2025 guidance supports PDE5 inhibitors as a first-line pharmacological option for erectile dysfunction . Better glucose, blood pressure, and lipid control can also improve treatment response.
What should I do if Avana does not work the first time?
Do not take an extra tablet on the same day. Consider practical factors such as a heavy meal, insufficient waiting time, alcohol, anxiety, inadequate stimulation, or an unsuitable dose. Clinicians often evaluate several properly timed attempts before deciding that a PDE5 inhibitor is ineffective. The FDA's 2022 label supports use only once per day, regardless of the result from the first attempt .
Can Avana be used with blood pressure medicine?
Some blood pressure treatments can be used alongside avanafil, while others need extra caution. Alpha-blockers and multiple blood-pressure medicines can amplify dizziness or a blood-pressure drop, especially when treatment begins. MOHAP guidance from 2024 expects medication interactions and cardiovascular fitness for sexual activity to be assessed before prescribing erectile dysfunction therapy. Nitrates remain an absolute contraindication.
Does Avana protect against sexually transmitted infections?
No. Avana affects penile blood flow only and does not prevent HIV, gonorrhoea, chlamydia, syphilis, or other sexually transmitted infections. WHO sexual-health guidance from 2022 continues to support barrier protection and testing strategies based on personal risk . Erectile dysfunction treatment and infection prevention address different health needs.

Diabetes had made erections less reliable. Avana helped when I gave it enough time and did not drink alcohol. The headache was noticeable at first, then became less of an issue.

The onset suited my schedule better than planning hours in advance. I found that stress still affected the result, so it was not a complete answer on difficult days.

I stopped after dizziness on the first use. I was also taking medicine for blood pressure, so the timing needed to be reviewed before I tried any erectile dysfunction treatment again.
