Avana (Avanafil) – Patient Information (Australia)

Avana (avanafil) is a medicine used to help men with erectile dysfunction (ED) achieve and maintain an erection suitable for sexual activity. This page explains how it works, how to use it safely, what to expect, and important interactions and precautions.

Important: Always follow the directions given to you by a healthcare professional and read the consumer medicines information (CMI) supplied with your product. If you have questions or symptoms that worry you, seek medical advice promptly.

Basic product information

How Avana works (mechanism of action)

Avanafil belongs to the PDE5 inhibitor class. In sexual stimulation, nitric oxide is released in the penis. This leads to increased levels of a substance called cGMP, which helps relax smooth muscle and increases blood flow to the erectile tissue.

PDE5 is an enzyme that breaks down cGMP. By inhibiting PDE5, avanafil helps maintain higher cGMP levels longer, which supports improved blood flow and helps you achieve an erection when you are sexually stimulated.

• It does not automatically cause an erection; sexual arousal is still required.
• It may help improve firmness and the ability to maintain an erection for sexual activity.

Pharmacokinetics (how your body handles it)

Pharmacokinetics describes how a medicine is absorbed, distributed, metabolised, and eliminated.

• Absorption: Avanafil is absorbed after oral dosing. Peak blood levels typically occur roughly within 30 minutes to 1 hour (timing varies between individuals).
• Onset: Many men can notice effects as early as 15–30 minutes, depending on dose and individual response.
• Distribution: It distributes through the body; it targets pathways involved in penile blood flow.
• Metabolism: Avanafil is primarily metabolised by liver enzymes, especially CYP3A4.
• Elimination: The medicine and its metabolites are eliminated mainly through hepatic (liver) pathways and ultimately eliminated from the body.

Because metabolism involves liver enzymes, drug interactions and liver health can influence how long Avana works and how strong the effects may be.

What Avana is typically used for

Avanafil is indicated for the treatment of erectile dysfunction, which is commonly defined as the consistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance.

It is generally used when ED has an ongoing pattern and lifestyle measures alone have not been sufficient. ED can be associated with cardiovascular risk factors, diabetes, hormonal changes, medication effects, stress, and other conditions—so it’s useful to discuss underlying causes with a clinician.

When to take Avana (timing)

Timing can significantly affect how quickly you feel effects.

• Typical approach: Take Avana prior to sexual activity.
• Usual timing: Many men take it about 15 to 30 minutes before planned sexual activity.
• Individual variation: Some men may need up to around 60 minutes for best effect, especially if the medicine is taken with a heavier meal.

Plan ahead: If you’re trying Avana for the first time, consider taking it on a day you can observe your response safely. Avoid combining it with other ED medicines unless your doctor specifically advises it.

Food interactions and eating

Food can affect the speed of absorption.

• Heavy or high-fat meals: These may slow absorption and delay onset.
• Faster effect: Taking Avana on a relatively lighter stomach may help it work sooner.

Practical suggestion: If you want effects to begin quickly, avoid taking it right after a large, fatty meal. If you only have a meal, consider allowing additional time before sexual activity.

Alcohol and medicine interactions

Alcohol

Alcohol can affect sexual performance by reducing blood flow and decreasing sexual drive. It can also increase the risk of dizziness or light-headedness.

• For best results, keep alcohol intake moderate.
• Avoid heavy drinking, especially when trying Avana for the first time.

Medicines interactions (important)

Avanafil can interact with medicines that affect blood pressure or liver metabolism (especially CYP3A4 inhibitors). These interactions can increase side effects or reduce effectiveness.

Do not take Avanafil if you use nitrate medicines for chest pain (angina) or you are taking riociguat. Combining these can cause a dangerous drop in blood pressure.

• Nitrates (example categories): nitroglycerin, isosorbide, and similar preparations.
• Riociguat: used for certain lung or blood pressure conditions.

Also be cautious with medicines that may lower blood pressure, such as some antihypertensives.

Other common interaction areas

• CYP3A4 inhibitors: Some antifungals, antibiotics (certain types), antivirals, and some medicines for heart rhythm issues can raise avanafil levels, increasing side effects.
• Alpha-blockers: Medicines used for prostate/urinary symptoms or blood pressure may cause dizziness or low blood pressure when combined. A clinician may advise timing or dose adjustments.
• Other ED medicines: Avoid taking multiple PDE5 inhibitors at the same time.
• Stimulants or recreational drugs: Some may worsen cardiovascular risk and increase side effects.

Always tell us (and your prescriber/doctor) about all medicines you take—prescription and non-prescription—including herbal products such as St John’s wort.

Indications: who Avana is for

Avanafil is used in adult men for the treatment of erectile dysfunction. It may be considered when ED affects sexual activity and quality of life.

It is not for women or children.

Not suitable for everyone: Some medical conditions may make PDE5 inhibitors unsafe. Seek medical advice before use if you have:

• Significant heart disease or an unstable cardiovascular condition
• Low blood pressure or history of fainting
• Serious liver impairment
• Serious kidney impairment
• A history of stroke or recent major heart event (timing varies)
• Specific eye conditions related to blood flow (your clinician can advise)

Dosing: typical adult use

Dosing may vary depending on your health status, response, and any interacting medicines. The goal is the lowest effective dose.

• Common starting dose: Many patients start at a lower dose to assess tolerance and effectiveness.
• How to adjust: Your clinician may increase or decrease the dose depending on response and side effects.
• Maximum frequency: Do not take more often than recommended on the product information.

How to take:

• Take by mouth with water.
• Take it before sexual activity.
• Do not exceed the advised dose.

Missed dose: Avana is taken before sexual activity. If you missed a planned dose, take it only if it fits your planned activity and dosing schedule; do not double up.

Safety profile and side effects

Like all medicines, avanafil can cause side effects. Not everyone gets them. Many are mild to moderate and improve as your body adjusts.

Common side effects

• Headache
• Flushing (warmth/redness of the face)
• Blocked or runny nose (nasal congestion)
• Dizziness
• Indigestion or mild stomach discomfort

Less common but serious risks (seek urgent medical advice)

• Chest pain or symptoms suggesting a heart problem
• Fainting or severe dizziness
• Sudden vision loss or severe changes in vision
• Sudden hearing changes (sometimes with ringing)
• Priapism: an erection lasting longer than expected (commonly >4 hours). This requires urgent treatment.
• Severe allergic reaction: swelling of face/lips, trouble breathing, severe rash

Cardiovascular considerations

Sexual activity itself exerts strain on the heart. If you have known cardiovascular disease, it’s wise to discuss whether sexual activity is safe for you. Some people may need a check-up before using ED medicines.

Practical use tips for better results

• Timing matters: Start with a dose and timing that matches your typical meals and schedule.
• Sexual stimulation is required: PDE5 inhibitors enhance the response but do not replace arousal.
• Give it a fair trial: Some men need more than one attempt to find the best dose and timing.
• Avoid double-dosing: If it doesn’t work, do not increase dose on the spot without advice.
• Choose a comfortable setting: Anxiety can worsen ED—calm, private conditions may improve outcomes.
• Supportive lifestyle steps: Reduce smoking, moderate alcohol, maintain activity, and manage diabetes and cholesterol where relevant.

Alternative options (if Avana isn’t suitable)

If avanafil is not appropriate or not effective for you, there are several other options depending on the cause of ED and your health:

• Other PDE5 inhibitors: Different PDE5 inhibitors may suit different people based on timing and tolerability.
• Non-PDE5 options: For some patients, clinicians may consider other medicines or treatment strategies.
• Devices: Vacuum erection devices can be effective for some men.
• Psychosexual support: Counselling may help when anxiety, relationship factors, or performance pressure contribute.
• Address underlying causes: Treatment of diabetes, sleep apnoea, hormonal issues (if present), and medication side effects can improve ED.

Tip: If you’re switching from one ED medicine to another, dosing and timing differ. Always seek advice before changing.

FAQ – Common questions about Avana (avanafil)

1) How quickly does Avanafil work?

Many men notice effects within 15–30 minutes, but it can take longer (often up to about 60 minutes), especially after a heavy meal. Individual response varies.

2) How long does Avana last?

Effects can last for several hours, but the exact duration differs by person. If you’re planning an encounter, allow enough time for the medicine to work and for sexual stimulation.

3) Can I take Avana with food?

Yes, but a heavy or high-fat meal may delay onset. For faster timing, consider taking it when you’ve eaten less heavily.

4) Can I drink alcohol with Avana?

Moderate alcohol is generally less likely to cause problems, but heavy drinking can reduce sexual performance and increase dizziness. Keep alcohol intake moderate and avoid binge drinking.

5) What medicines should I avoid?

Do not use Avanafil with nitrates (often used for angina) or riociguat. Also be cautious with medicines that affect blood pressure or liver metabolism (e.g., certain antibiotics/antifungals or other CYP3A4-related medicines). Always check interactions with a clinician or pharmacist.

6) Is Avanafil safe for men with heart disease?

It may not be suitable for everyone. Sexual activity and ED medications both involve cardiovascular considerations. If you have heart disease, you should talk to a healthcare professional before use.

7) What should I do if it doesn’t work?

First, ensure timing and sexual stimulation are appropriate. Avoid taking extra doses beyond the recommended schedule. Review possible factors such as meal timing, alcohol, stress, and interacting medicines. If persistent, consider speaking to a clinician to assess the cause of ED and whether a different treatment is better.

8) What side effects are normal?

Common effects include headache, flushing, and nasal congestion. If side effects are severe, persistent, or you develop serious symptoms (chest pain, fainting, vision changes, hearing changes, priapism), seek urgent medical help.

9) Can I take Avana with other ED medicines?

Do not combine PDE5 inhibitors unless specifically instructed by a healthcare professional. Combining can increase side effects and risk.

10) What if I get an erection that won’t go away?

If you have an erection lasting longer than expected (commonly over 4 hours), seek urgent medical care—this may be priapism.

11) Who should not use Avanafil?

Men who use nitrates or riociguat should not use it. Others may need caution depending on cardiovascular status, blood pressure, liver impairment, and interacting medications. If you are unsure, get medical advice.

When to seek medical advice

Get medical help promptly if you experience:

• Chest pain, severe dizziness, or fainting
• Sudden changes in vision or hearing
• An erection that lasts too long
• Symptoms of a severe allergic reaction

Also speak to a clinician if your ED is new, worsening, or associated with other symptoms—because ED can sometimes be an early sign of underlying health conditions.
