Anyone who’s tried to manage erectile dysfunction (ED) quickly learns that not all pills are created equal. Viagra Professional is often the first name that pops up, but dozens of alternatives promise faster onset, longer lasting effects, or a gentler side‑effect profile. This guide breaks down how Viagra Professional (Sildenafil) stacks up against the most common competitors, so you can pick the option that fits your schedule, budget, and health needs.
Key Takeaways
- Viagra Professional delivers a reliable response in 30‑60 minutes and lasts about 4‑6 hours.
- Cialis (Tadalafil) works in as little as 15 minutes and can stay effective for up to 36 hours.
- Levitra (Vardenafil) offers a slightly quicker onset than Viagra but a similar duration.
- Stendra (Avanafil) boasts the fastest onset-often under 15 minutes-with fewer visual side effects.
- Generic sildenafil provides the same chemistry as Viagra Professional at a fraction of the price, though brand‑name consistency can vary.
Below, we’ll define each pill, compare their performance, and walk through the factors you should weigh before choosing.
What is Viagra Professional (Sildenafil)?
Viagra Professional is a prescription tablet that contains 100mg of sildenafil citrate. It works by blocking the enzyme phosphodiesterase‑5 (PDE‑5), which allows blood vessels in the penis to relax and fill with blood during sexual stimulation. Most men notice an erection within 30‑60 minutes, and the effect can last 4‑6 hours, giving a reasonable window for intimacy.
Typical dosing starts at one tablet taken about an hour before activity, with the option to adjust up or down based on response and tolerance. Because it’s a high‑strength version, it’s often prescribed to men who need a stronger dose than the standard 50mg tablet.
Major Alternatives on the Market
Below are the most frequently prescribed ED medications that compete directly with Viagra Professional:
- Cialis (Tadalafil) - known for its "weekend pill" effect.
- Levitra (Vardenafil) - a close chemical cousin of sildenafil.
- Stendra (Avanafil) - the newest generation with rapid onset.
- Generic sildenafil - chemically identical to Viagra Professional but sold under various brand names.
- Herbal options such as L‑arginine and ginseng - often marketed as natural boosters.

Side‑Effect Profiles Compared
All PDE‑5 inhibitors share a core set of possible side effects: headaches, flushing, nasal congestion, and upset stomach. However, individual compounds differ in how often these occur and what extra risks may appear.
- Viagra Professional: Visual disturbances (blue‑tinted vision) affect less than 1% of users; mild headache is the most common complaint.
- Cialis: Muscle aches and back pain can surface, especially with higher daily doses.
- Levitra: Slightly higher rate of dizziness, but usually short‑lived.
- Stendra: Rare visual side effects; most users report only mild flushing.
- Generic sildenafil: Mirrors the brand’s side‑effect profile, though tablet consistency can vary.
- Herbal supplements: Potential interactions with blood thinners and variable potency, making them less predictable.
Performance Snapshot
Brand | Active ingredient | Typical dose | Onset | Duration | Average cost (AU$) |
---|---|---|---|---|---|
Viagra Professional | Sildenafil | 100mg | 30‑60min | 4‑6hrs | ≈$30 per tablet |
Cialis | Tadalafil | 10mg (as needed) / 2.5mg (daily) | 15‑30min | Up to 36hrs | ≈$35 per 10mg tablet |
Levitra | Vardenafil | 20mg | 25‑60min | 4‑5hrs | ≈$28 per tablet |
Stendra | Avanafil | 100mg | <15min | 6‑12hrs | ≈$40 per tablet |
Generic sildenafil | Sildenafil | 100mg | 30‑60min | 4‑6hrs | ≈$10 per tablet |
How to Choose the Right Option
Picking a pill isn’t just about price; it’s about how the drug fits your lifestyle.
- Timing needs: If you want spontaneity on weekends, Cialis’s long window may be ideal. For a quick, on‑the‑spot boost, Stendra edges out the competition.
- Side‑effect tolerance: Men who notice visual changes with sildenafil might switch to Avanafil or Tadalafil.
- Budget constraints: Generic sildenafil gives you the same chemistry as Viagra Professional for roughly a third of the cost.
- Health considerations: If you’re on nitrates or have severe heart disease, none of the PDE‑5 inhibitors are safe; you’ll need a physician‑guided alternative.
- Frequency of use: Daily low‑dose Cialis works well for men who have frequent sexual activity, while an as‑needed approach suits occasional use.

Practical Tips for Safe Use
- Take the tablet with water, not a heavy meal, as fatty foods can delay absorption.
- Allow at least 24 hours between sildenafil doses; Tadalafil can be taken daily under a doctor’s supervision.
- Avoid alcohol excess; it can compound dizziness and lower blood pressure.
- Inform your doctor about any heart medications, especially nitrates, to prevent dangerous interactions.
- If you experience a prolonged erection lasting more than 4 hours, seek medical help immediately.
Common Misconceptions Debunked
Many men think a higher dose always means a stronger erection. In reality, increasing the dose past the recommended level only raises side‑effect risk without guaranteeing better performance. Similarly, "herbal" doesn’t automatically equal safety; supplements like yohimbe have been linked to serious cardiovascular events.
Frequently Asked Questions
Can I switch from Viagra Professional to a generic version without a new prescription?
Yes, generic sildenafil contains the same active ingredient, so your doctor can simply note the change on the prescription. Pharmacists often dispense the generic automatically if it’s cheaper.
Is it safe to take a daily low dose of Cialis?
Daily dosing (2.5mg) is approved for men with frequent sexual activity and has been shown to be well‑tolerated in clinical trials. Still, you need a doctor’s approval because it interacts with some heart medications.
Do herbal supplements work as well as prescription pills?
Research on L‑arginine, ginseng, and similar herbs shows modest improvement for some men, but the effect is far weaker than PDE‑5 inhibitors. They can be useful as adjuncts, not replacements.
What should I do if my erection lasts longer than 4 hours?
Seek emergency medical attention right away. A prolonged erection (priapism) can damage penile tissue if not treated promptly.
Can I take Viagra Professional with alcohol?
A moderate amount (one or two drinks) usually doesn’t cause problems, but heavy drinking can lower blood pressure and increase the chance of dizziness.
Next Steps
Talk to your GP or a qualified urologist about your specific health profile. Bring a list of any current medications, and ask whether a daily low‑dose Tadalafil, an as‑needed Sildenafil, or a trial of Stendra best matches your goals. Once you have a prescription, compare pharmacy prices-online dispensaries often list lower rates for generics, while some bulk‑buy programs discount brand names.
Remember, the right pill is the one that lets you feel confident without unwanted side effects. Use the comparison chart above as a reference, but let your doctor’s advice guide the final decision.
