Erectile dysfunction (ED) is a common health concern that can affect adult men for several reasons. When erectile difficulties persist, a healthcare professional may recommend treatment after assessing possible underlying causes and individual health needs.

One prescription medicine used to manage erectile dysfunction is avanafil, which belongs to a group of medicines called PDE5 inhibitors.

Adults researching avanafil may encounter several tablet strengths, including 200 mg. However, choosing a higher strength does not necessarily provide better results.

In Australia, avanafil is a prescription-only medicine. Understanding its uses, dosage considerations, side effects and potential interactions is essential before treatment.

What Is Avanafil and How Does It Work?

Avanafil is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction in adult men.

Other medicines in this category include sildenafil, tadalafil and vardenafil.

During sexual stimulation, the body releases substances that help relax blood vessels in the penis. Avanafil supports this natural process by inhibiting the PDE5 enzyme, allowing increased blood flow.

This can help suitable patients achieve or maintain an erection.

However, avanafil does not:

• Automatically produce an erection

• Increase sexual desire

• Permanently cure erectile dysfunction

• Prevent sexually transmitted infections

• Provide contraception

Sexual stimulation is still necessary for the medicine to work.

Are Avanafil Tablets Available in Australia?

Yes. Avanafil is available in Australia as the prescription medicine Spedra.

The Australian-registered product is available in 50 mg, 100 mg and 200 mg strengths.

People researching avanafil tablets should understand that obtaining this medicine requires an appropriate prescription.

A healthcare professional should assess the patient's medical history, cardiovascular health, current medications and suitability for treatment.

Consumers should also distinguish between Australian-registered medicines and overseas products claiming to contain the same active ingredient.

The Therapeutic Goods Administration (TGA) recommends checking the Australian Register of Therapeutic Goods (ARTG) when verifying a medicine's regulatory status.

What Does Avanafil 200 mg Mean?

The 200 mg strength refers to the amount of avanafil contained in each tablet.

However, avanafil 200 mg is not the recommended starting dose for every patient.

According to Australian Spedra prescribing information, the recommended dose is generally 100 mg, taken as needed before anticipated sexual activity.

Depending on effectiveness and tolerability, a prescriber may increase the dose to a maximum of 200 mg or reduce it to 50 mg.

Does a Higher Dose Mean Better Results?

Not necessarily.

The Australian product information notes that the additional benefit of the 200 mg dose may be limited.

Dose selection depends on factors such as:

• Individual response to treatment

• Previous side effects

• Existing medical conditions

• Other prescription medicines

• Cardiovascular health

Patients should never increase their prescribed dose independently.

How Is Avanafil Usually Taken?

The Australian Consumer Medicine Information for Spedra recommends taking the prescribed dose approximately 15–30 minutes before anticipated sexual activity.

The medicine may be taken with or without food, although food can affect how quickly it starts working.

The recommended maximum frequency is one dose within 24 hours, with additional restrictions applying to certain medicine combinations.

Patients should always follow their prescriber's specific instructions.

If treatment does not provide the expected response, speak with a healthcare professional rather than taking additional tablets.

What Are the Possible Side Effects?

Like other prescription medicines, avanafil can cause unwanted reactions.

Common Side Effects

Possible side effects include:

• Headache

• Facial flushing

• Nasal congestion

• Dizziness

• Changes in blood pressure

Individual responses may vary.

Persistent or concerning symptoms should be discussed with a doctor or pharmacist.

Serious Side Effects

Although less common, serious reactions may require urgent medical attention.

These include sudden vision or hearing loss, chest pain, severe allergic reactions and an erection lasting longer than four hours.

A prolonged erection requires emergency medical assessment because it can cause permanent tissue damage.

Patients should read the Consumer Medicine Information supplied with their prescribed medicine.

Important Medicine Interactions

Avanafil can interact with several medicines, potentially causing serious complications.

Nitrates and Blood Pressure

Avanafil must not be combined with nitrate medicines used for conditions such as angina.

Combining these medicines can cause a dangerous reduction in blood pressure.

Nitrate medicines may include glyceryl trinitrate and isosorbide preparations.

Other Medicines Requiring Caution

Certain antifungal medicines, antibiotics and HIV treatments can interfere with how avanafil is processed by the body.

Some combinations are contraindicated, while others require dose restrictions.

Avanafil must also not be combined with riociguat.

Before using avanafil, tell your doctor about all prescription medicines, over-the-counter products and supplements you take.

Why Cardiovascular Assessment Matters

Erectile dysfunction can sometimes be associated with underlying cardiovascular conditions.

Additionally, sexual activity places physical demands on the heart.

For these reasons, healthcare professionals may assess cardiovascular health before prescribing avanafil.

The medicine may be unsuitable for people with certain serious heart conditions, recent cardiovascular events or significant blood-pressure abnormalities.

Medical assessment also provides an opportunity to investigate other potential causes of ED, including diabetes, hormonal changes, medication effects and psychological factors.

Can Avanafil Be Combined With Other ED Medicines?

Avanafil should not be combined with sildenafil, tadalafil, vardenafil or other erectile dysfunction medicines without specialist medical direction.

Combining PDE5 inhibitors may increase the likelihood of adverse reactions.

If treatment is not working as expected, a healthcare professional can review the prescribed dose, timing, underlying conditions and alternative treatment options.

Self-adjusting doses or combining medicines can create unnecessary risks.

Important Checks Before Using Avanafil

Before taking avanafil, consider the following questions:

1. Has my erectile dysfunction been professionally assessed?

2. Is avanafil appropriate for my medical history?

3. Is the prescribed strength suitable?

4. Have all potential medicine interactions been reviewed?

5. Are there cardiovascular concerns?

6. Is the medicine supplied through a legitimate pharmacy?

7. Have I read the Consumer Medicine Information?

These checks help ensure that treatment decisions are based on medical suitability rather than online advertisements or assumptions about tablet strength.

Final Thoughts

Avanafil is a prescription PDE5 inhibitor used to manage erectile dysfunction in adult men.

Although 200 mg tablets are available in Australia, this is not the recommended starting dose for everyone.

The appropriate strength depends on individual response, medical history, other medicines and potential side effects.

Nitrate interactions and cardiovascular health are particularly important safety considerations.

Australian patients should obtain avanafil through legitimate prescription pathways and follow professional medical advice.

The most important consideration is not choosing the highest strength, but using a medicine and dose that are appropriate for individual health needs.
