If you’ve ever wondered whether the brand‑name pill you’re taking is the best fit for your life, you’re not alone. Men across Australia and beyond constantly weigh the benefits of Viagra Professional is a pharmaceutical formulation of sildenafil citrate, a phosphodiesterase‑5 (PDE5) inhibitor approved for treating erectile dysfunction (ED). The real question isn’t just “does it work?” but “how does it compare to the other options on the market?” This guide breaks down the key differences, helping you decide which medication (or lifestyle tweak) aligns with your priorities.
What is erectile dysfunction and why PDE5 inhibitors matter?
Erectile dysfunction is a chronic condition where a man cannot achieve or maintain an erection sufficient for sexual activity. The condition affects roughly 1 in 10 men aged 40‑70, according to the Australian Institute of Health. PDE5 inhibitors work by relaxing smooth muscle in the penis, allowing increased blood flow when sexual stimulation occurs. This class has become the first‑line treatment because it’s effective, oral, and relatively safe when used as directed.
Key players in the PDE5 arena
Beyond Viagra Professional, four other branded drugs dominate the Australian market:
- Cialis (tadalafil) is a longer‑acting PDE5 inhibitor, often taken daily in low doses or as needed.
- Levitra (vardenafil) offers a slightly faster onset, with a profile similar to sildenafil.
- Stendra (avanafil) is the newest entrant, marketed for a rapid 15‑minute onset.
- Generic sildenafil provides the same active ingredient as Viagra Professional at a lower price point.
All five belong to the PDE5 inhibitor class, sharing a core mechanism but differing in dosage, duration, and side‑effect nuances.
How do they stack up? Comparison table
Medication | Typical Dose | Onset of Action | Effective Window | Common Side Effects | Average Cost (AU$) |
---|---|---|---|---|---|
Viagra Professional (sildenafil) | 50mg (adjustable 25‑100mg) | 30‑60min | 4‑6hr | Headache, flushing, dyspepsia | ~$45 per tablet |
Generic sildenafil | Same as brand | 30‑60min | 4‑6hr | Headache, nasal congestion | ~$12 per tablet |
Cialis (tadalafil) | 10mg as needed or 2.5mg daily | 15‑30min | Up to 36hr (as needed) | Back pain, muscle aches | ~$55 per tablet (as needed) |
Levitra (vardenafil) | 20mg (adjustable 5‑20mg) | 25‑60min | 4‑5hr | Headache, dizziness | ~$48 per tablet |
Stendra (avanafil) | 100mg (adjustable 50‑200mg) | 15‑30min | 6‑12hr | Rash, nasal congestion | ~$70 per tablet |
When to choose Viagra Professional
Viagra Professional shines in three scenarios:
- Predictable timing: If you can plan intimacy 30‑90 minutes beforehand, the 30‑60 minute onset offers reliable performance.
- Cost vs. brand confidence: While generic versions are cheaper, some men prefer the brand’s consistent tablet integrity and packaging.
- Compatibility with other meds: Sildenafil has a well‑documented interaction profile, making it easier for physicians to assess safety alongside antihypertensives.
Clinical guidelines from the Royal Australian College of General Practitioners (RACGP) recommend starting with a low dose of sildenafil and adjusting based on response, reinforcing its status as the first‑line choice for many doctors.

When alternatives make more sense
Each competitor addresses a specific need that Viagra Professional may not cover.
- Longer spontaneity: Cialis’s 36‑hour window lets couples stay flexible without timing the pill.
- Rapid onset for last‑minute plans: Stendra’s 15‑minute kick‑off works when you’re already in the mood.
- Lower daily dosing: For men who prefer a daily pill rather than “as‑needed,” low‑dose tadalafil can maintain readiness without thinking about timing.
- Fewer visual side effects: Some users report less colour distortion with vardenafil, making Levitra a comfortable alternative.
Insurance coverage also sways choice. Many private health funds in Australia cover generic sildenafil but not the newer brand‑only options, making cost a decisive factor.
Safety, side‑effects, and contraindications
All PDE5 inhibitors share a safety framework, yet each has quirks.
Medication | Headache | Flushing | Back Pain | Visual Disturbance |
---|---|---|---|---|
Viagra Professional | ✓ | ✓ | Rare | |
Generic sildenafil | ✓ | ✓ | Rare | |
Cialis | ✓ (up to 48hr) | |||
Levitra | ✓ | Occasional | ||
Stendra | Very rare |
Absolute contraindications include concurrent nitrate therapy (e.g., nitroglycerin for angina) and severe uncontrolled hypertension. Partial contraindications involve certain eye conditions (retinitis pigmentosa) and recent stroke. Discussing your full medication list with a GP or urologist is essential before starting any PDE5 inhibitor.
Practical tips for getting the best results
- Take the pill on an empty stomach. High‑fat meals can delay absorption, especially for sildenafil.
- Avoid alcohol excess. While a modest drink won’t kill the effect, heavy drinking can blunt the response.
- Maintain a healthy lifestyle. Regular exercise, weight management, and quitting smoking improve overall erectile function and may reduce the needed dose.
- Track your response. Simple notes on timing, effectiveness, and side‑effects help you and your doctor fine‑tune the regimen.
- Consider telehealth. In 2024, the Australian government expanded subsidised tele‑consults, making it easier to get a prescription without lengthy GP visits.

Frequently Asked Questions
Is Viagra Professional more effective than generic sildenafil?
The active ingredient is identical, so clinical efficacy is the same. Differences lie in tablet excipients, price, and perceived brand reliability. Some men report a slightly smoother onset with the brand, but studies show no statistically significant efficacy gap.
Can I switch between sildenafil and tadalafil without a doctor’s approval?
No. Both drugs require a prescription in Australia, and each has specific dosing rules and contraindications. Switching without medical guidance could increase risk of adverse reactions, especially if you have heart disease or are on nitrate medication.
How long does a typical prescription for ED medication last?
Most GPs prescribe a 3‑month supply, providing enough tablets for regular use. If you’re on a daily low‑dose regimen (e.g., Cialis 2.5mg), a 90‑day repeat is common. Your doctor may adjust the interval based on response and side‑effects.
Are there any food interactions I should avoid?
Heavy, high‑fat meals can delay the absorption of sildenafil and vardenafil, reducing peak concentration by up to 30%. Tadalafil and avanafil are less affected but still benefit from a lighter meal or fasting period of 1‑2hours before dosing.
What should I do if I experience a painful erection lasting more than 4 hours?
Seek emergency medical attention immediately. A prolonged erection (priapism) can damage penile tissue. While rare, it’s a known risk, especially if you exceed the recommended dose or combine with other vasodilators.
