Basic Product Information
Avana (avanafil) is an oral tablet medicine. Avanafil is designed to treat erectile dysfunction by enhancing the body’s natural response to sexual stimulation.
- Brand name: Avana
- Generic name: avanafil
- Dosage strengths: Available strengths may vary by product/market packaging.
- Route: Oral (swallowed by mouth)
Availability in Australia may depend on local approvals, supply, and distribution through pharmacy channels. If you’re unsure whether Avana is right for you or which strength is suitable, speak with a pharmacist.
How Avana Works (Mechanism of Action)
Sexual arousal triggers release of nitric oxide in the penis. This increases cGMP levels, which helps relax smooth muscle cells and allows increased blood flow—leading to an erection.
Avanafil works by inhibiting PDE5 (phosphodiesterase type 5), an enzyme that breaks down cGMP. By blocking PDE5, Avana helps maintain higher cGMP levels for longer, which supports erection quality and duration when you are sexually stimulated.
Key point: Avana does not automatically create an erection. It supports erections in response to sexual stimulation.
Pharmacokinetics (How the Body Handles Avana)
Understanding onset and duration can help you plan your dose appropriately.
Absorption
Avanafil is absorbed after oral dosing. The time to feel effects can vary between individuals and depends on factors such as food intake.
Onset of action
Clinical use commonly reflects an onset within about 15–30 minutes for many men, though some may need more time. Your personal response may differ.
Distribution
After absorption, avanafil distributes throughout the body. It is metabolised mainly in the liver.
Metabolism and elimination
Avanafil is metabolised primarily by hepatic enzymes (notably CYP3A4). Metabolites are eliminated mainly via urine and to a lesser extent via faeces.
Because metabolism can be affected by other medicines (especially those that influence CYP3A4), drug–drug interactions are important for safety.
What Avana Is Typically Used For
Avana is used to treat erectile dysfunction (ED) in adult men. ED may be caused by a range of factors, including vascular problems, diabetes, stress, or other health conditions.
If ED is new, worsening, or associated with symptoms such as chest pain, shortness of breath, or fainting, seek medical advice promptly—ED can sometimes be a sign of underlying cardiovascular disease.
Indications and When It’s Appropriate
Avana is generally indicated for men with ED who can safely use PDE5 inhibitors. It may be considered when lifestyle measures and addressing underlying factors are not enough on their own.
- For: Improving the ability to achieve and maintain an erection during sexual activity
- Not for: Women, children, or adolescents
- Not a fertility or libido medicine: It supports erections when arousal is present
Dosing: Typical Adult Use
Dosing can vary by product strength and individual response. Always follow the directions provided by your healthcare professional or pharmacist. The information below describes typical dosing patterns used for ED.
Typical timing and frequency
- Take Avana before sexual activity.
- Many men aim for dosing about 15–30 minutes before sex, but follow your clinician’s instructions and your experience.
- Do not exceed the maximum frequency (commonly once per day) unless advised otherwise.
Common dose adjustment considerations
- If you experience side effects (e.g., headache, flushing, dizziness), you may need a different dose.
- Medicines that increase avanafil levels (e.g., some antibiotics/antifungals/antivirals) may require dose changes or avoidance.
- In men with liver or kidney impairment, dosing may need adjustment.
Missed dose
Avana is used on-demand before sex rather than on a strict daily schedule. If you did not take it before activity, do not take extra doses to “catch up.” Use your next planned dose as advised.
Timing With Food: Food Interactions
Food can affect how quickly Avanafil works. For best results, consider the following general guidance:
- High-fat meals: May delay onset. If you’ve eaten a large, fatty meal, you may need to allow more time before sexual activity.
- Fasting or lighter meals: May help the medicine start working sooner.
- Consistency: If you notice your response changes with meals, try to keep timing and meal type similar on future attempts.
If you have specific dietary habits (e.g., frequent high-fat meals) or digestive issues, ask your pharmacist for tailored advice.
Alcohol: Effects and Safety
Alcohol can worsen ED in multiple ways, including reducing erection quality and increasing the likelihood of dizziness. When combined with PDE5 inhibitors, alcohol may increase side effects such as:
- Dizziness or light-headedness
- Flushing
- Headache
- Lower blood pressure symptoms (especially if you’re sensitive)
Practical tip: If you choose to drink, consider keeping alcohol modest and allow time to see how you respond. Avoid driving or operating machinery if you feel dizzy.
Medicine Interactions: What to Avoid and What to Be Cautious With
Drug interactions are a crucial safety topic for PDE5 inhibitors. Some combinations can cause a dangerous drop in blood pressure. Always tell your pharmacist or doctor about all medicines you take, including over-the-counter products and herbal supplements.
Absolute or strongly contraindicated combinations
- Nitrates (e.g., glyceryl trinitrate/nitroglycerin, isosorbide mononitrate/dinitrate) used for chest pain: Do not combine with PDE5 inhibitors.
- Riociguat: Do not combine.
CYP3A4 inhibitors (can increase avanafil levels)
Avanafil is metabolised largely via CYP3A4. Medicines that inhibit CYP3A4 can raise avanafil blood levels, increasing side effects and potentially requiring dose changes.
- Some antibiotics
- Some antifungal medicines
- Some antiviral medicines used for HIV or hepatitis
- Some heart or blood pressure medicines (depending on what’s being taken)
This does not list every medicine. Your pharmacist can check your exact regimen for interaction risk.
Alpha-blockers (for prostate symptoms or high blood pressure)
If you take an alpha-blocker, the combination may affect blood pressure. Some patients can use them safely with careful timing and monitoring, but you should discuss dosing and stability of blood pressure with a clinician.
Other blood pressure medicines
Avana may add to the blood pressure-lowering effects of certain medicines. If you’re prone to low blood pressure, dizziness, or fainting, consult a healthcare professional before using PDE5 inhibitors.
“Lifestyle” interactions
- Smoking and excessive alcohol can reduce erectile function over time.
- Recreational drugs (including stimulants) can be dangerous in combination with PDE5 inhibitors due to effects on the heart and blood vessels.
Safety Profile: Side Effects and Warning Signs
Most men tolerate Avana well, but like all medicines it can cause side effects. Many side effects are mild and temporary. However, you should be aware of warning signs that require urgent medical attention.
Common side effects
- Headache
- Flushing (warmth or redness of the face)
- Stuffy or runny nose
- Dizziness
- Indigestion or mild gastrointestinal discomfort
- Back pain (reported in some users)
Less common but important side effects
- Vision changes or sudden eye pain
- Hearing changes or sudden ringing in the ears
- Prolonged erection (priapism) lasting more than 4 hours
- Fainting or severe dizziness
- Chest pain or symptoms of severe cardiovascular strain
Seek urgent help if
- An erection lasts more than 4 hours
- You experience severe dizziness, fainting, or signs of a serious allergic reaction
- You have sudden vision loss or severe eye symptoms
- You develop severe chest pain
Who should use caution
People with certain medical conditions may need extra caution or may not be suitable for Avana. Discuss with a clinician if you have:
- Known heart disease or unstable cardiovascular conditions
- Very low blood pressure or history of fainting
- Severe liver impairment
- Severe kidney impairment
- Conditions affecting blood flow to the retina or certain eye disorders
- A history of priapism or certain blood disorders (e.g., sickle cell disease)
Practical Use Tips (Maximise Effect and Minimise Issues)
The following practical tips can improve results and reduce the chance of side effects.
Before you take Avana
- Check interactions: Ensure you’re not using nitrates or riociguat.
- Review medicines: Include all prescriptions, pharmacy items, and supplements.
- Plan timing: Allow time before sex—especially if you’ve eaten.
During use
- Sexual stimulation is required: Give yourself time for arousal; the medicine works with your natural response.
- Start with a safe approach: If you’re new to PDE5 inhibitors, avoid heavy alcohol and plan for a comfortable environment.
- Observe your response: If onset is slower than expected, consider adjusting timing in future attempts (discuss with your pharmacist/doctor if changing the dose schedule).
If it doesn’t work as expected
- Timing may be the issue: Try again with a different interval from food and activity.
- Dose may need adjustment: Do not increase above recommended limits without medical advice.
- Consider underlying factors: Diabetes, smoking, stress, and cardiovascular health can all affect erections.
