When it comes to treating erectile dysfunction, Cialis Professional is a brand‑name formulation of the active ingredient tadalafil that offers a longer window of action compared with many rivals. If you’re weighing your options, you’ll want to know how it stacks up against the most common alternatives, what the real differences are, and which factors matter most for your lifestyle.
What is Cialis Professional (Tadalafil)?
Tadalafil is a phosphodiesterase‑5 (PDE5) inhibitor approved for erectile dysfunction (ED) and, at a lower dose, for benign prostatic hyperplasia. The “Professional” version is a prescription‑only tablet that contains 20mg of tadalafil, designed for men who need a reliable, on‑demand solution with a flexible timing window.
How do PDE5 inhibitors work?
All the major ED drugs-Sildenafil (brandViagra), Vardenafil (brandLevitra), and Avanafil (brandStendra)-share the same basic mechanism. They block the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). By preserving cGMP, blood flow to the penile tissue improves, allowing an erection in response to sexual stimulation.
Key differences: Onset, Duration, and Dosing
While the biochemical action is similar, the pharmacokinetics vary:
- Cialis Professional: Takes about 30‑60minutes to work, but the effect can last up to 36hours.
- Sildenafil (Viagra): Starts in 15‑30minutes, lasting roughly 4‑6hours.
- Vardenafil (Levitra): Similar onset to sildenafil, with a 4‑5hour window.
- Avanafil (Stendra): Fastest onset (as little as 15minutes) and a duration of 6‑12hours.
Because Cialis Professional stays active for so long, many users treat it as a “weekend pill,” taking it Thursday night for Saturday plans. The other drugs usually require a tighter schedule, timed closer to the intended activity.
Safety profile and side‑effects
All PDE5 inhibitors share a core set of possible side‑effects: headache, flushing, nasal congestion, and upset stomach. However, the frequency and intensity can differ:
- Cialis Professional - Muscle aches and back pain are more common, especially at the 20mg dose, due to the drug’s longer half‑life.
- Sildenafil - Visual disturbances (blue‑tint vision) occur in a small percentage of users.
- Vardenafil - Similar to sildenafil but with slightly higher reports of dizziness.
- Avanafil - Generally the mildest side‑effect profile, though rare cases of sudden hearing loss have been reported.
The FDA requires a warning about possible cardiovascular risks for any PDE5 inhibitor. Men with unstable angina, recent heart attack, or severe hypertension should discuss options with their doctor before starting any medication.

Drug interactions and contraindications
Because PDE5 inhibitors are metabolized by the liver enzyme CYP3A4, they can interact with a range of other medicines. Nitrates (often prescribed for chest pain) are a strict contraindication-combining them can cause a dangerous drop in blood pressure. Other notable interactions include:
- Alpha‑blockers (used for prostate issues) - may cause additive blood‑pressure effects.
- Certain antifungals and antibiotics - can raise plasma levels of the ED drug, increasing side‑effect risk.
- Grapefruit juice - especially with tadalafil, can slow metabolism and prolong exposure.
Always review your full medication list with a pharmacist or physician before picking an ED treatment.
Cost, insurance coverage, and accessibility
Price is a practical factor many people consider. In Australia, the cost per tablet varies:
- Cialis Professional (20mg) - Approximately AU$30‑$45 per pill, depending on pharmacy pricing.
- Sildenafil (Viagra) - Roughly AU$20‑$35 for a 50mg tablet.
- Vardenafil (Levitra) - Similar to sildenafil, around AU$22‑$38.
- Avanafil (Stendra) - Typically the most expensive, up to AU$45‑$55 per 100mg tablet.
Private health insurance may cover a portion of the cost for any of these drugs if a doctor provides a prescription, but coverage limits differ. Online telehealth services have made it easier to obtain a prescription and sometimes offer bulk‑discount pricing.

How to decide which option fits you best
Choosing the right ED medication isn’t just about price or how long it lasts. Ask yourself these practical questions:
- Do you need spontaneity, or can you plan ahead? If you want a “take‑it‑any‑time” pill, Cialis Professional’s 36‑hour window is a strong advantage.
- Are you on other medications that might interact? Tadalafil’s longer half‑life means it stays in your system longer, raising the stakes for certain drug interactions.
- How sensitive are you to side‑effects? If muscle aches have bothered you in the past, a lower‑dose daily tadalafil regimen or switching to sildenafil might be gentler.
- What does your budget allow? For occasional use, the cheaper per‑pill cost of sildenafil could make sense, while daily low‑dose tadalafil might be cost‑effective for frequent use.
Discuss these points with a healthcare professional who can tailor the prescription to your health profile and lifestyle.
Frequently Asked Questions
Frequently Asked Questions
Can I take Cialis Professional every day?
Yes, a lower‑dose daily version of tadalafil (2.5mg or 5mg) is approved for daily use. The 20mg Professional tablet is meant for on‑demand use only.
Is it safe to combine Cialis Professional with alcohol?
Moderate alcohol is generally fine, but heavy drinking can worsen side‑effects like dizziness or low blood pressure. Keep consumption moderate and talk to your doctor if you have heart concerns.
How quickly does Cialis Professional work compared to Viagra?
Viagra often starts in 15‑30minutes, while Cialis Professional usually takes 30‑60minutes. The trade‑off is that Cialis stays effective for up to a day and a half.
What should I do if I miss a dose of my daily tadalafil?
Take the missed tablet as soon as you remember, unless it’s close to the time of your next dose. In that case, skip the missed pill-don’t double‑dose.
Are there any foods that affect how Cialis Professional works?
A high‑fat meal can delay absorption slightly, but the effect isn’t as pronounced as with some other ED drugs. For best results, take the tablet with a light meal or on an empty stomach.
By weighing onset time, duration, side‑effects, cost, and personal health factors, you can pinpoint whether Cialis Professional or another PDE5 inhibitor suits you best. Remember, the final decision should always involve a qualified healthcare provider who can tailor the prescription to your unique profile.

Life’s choices are a reflection of the very chemistry we ingest; we either chase the instant spark or we honor the lingering flame. In the arena of erectile aids, the allure of a 36‑hour horizon tempts the strategist, while the fleeting pulse of a four‑hour pill suits the impulsive. The question is not merely how fast it works, but how it fits into the cadence of one’s existence. One must weigh the silence of muscle aches against the freedom of unplanned intimacy.
