When it comes to treating erectile dysfunction (ED), many men wonder whether the higher‑dose version of Cialis is really worth the extra milligrams. Cialis Extra Dosage (Tadalafil) is a prescription‑only formulation that delivers 20 mg of tadalafil per tablet, compared with the standard 10 mg strength. This article breaks down how that strength stacks up against the most common alternatives, so you can decide if the extra dose fits your lifestyle, budget, and health profile.
How Tadalafil Works and What the Extra Dose Changes
Tadalafil belongs to the phosphodiesterase‑type 5 (PDE5) inhibitor class. By blocking the PDE5 enzyme, it helps keep cyclic guanosine monophosphate (cGMP) in the penis, allowing blood vessels to stay relaxed during sexual stimulation. The result is a firmer, longer‑lasting erection.
The standard 10 mg tablet starts working within 30‑60 minutes and can last up to 36 hours. The 20 mg version simply delivers twice the amount of active ingredient, which can translate into a slightly faster onset for some men and a marginally higher chance of achieving an erection in borderline cases. However, the extra milligrams also raise the likelihood of side effects such as headache, flushing, or dyspepsia.
Dosage Options, Timing, and Flexibility
- Standard Cialis (10 mg): Take as needed, 30 minutes before intimacy. Can be taken up to once daily.
- Cialis Extra Dosage (20 mg): Same timing, but recommended for men who did not respond adequately to 10 mg.
- Daily Low‑Dose Cialis (2.5 mg or 5 mg): Taken every day at the same time, providing continuous readiness.
- Other PDE5 inhibitors (see below): Usually taken 30‑60 minutes before sex; duration varies from 4‑6 hours (Viagra) to 12‑15 hours (Stendra).
Choosing the right schedule depends on how often you anticipate sexual activity and whether you prefer a “on‑demand” pill or a daily regimen.
Key Criteria for Comparing ED Medications
Every comparison needs a set of measurable factors. Here are the five most relevant criteria for men evaluating Cialis extra dosage against alternatives:
- Effectiveness - percentage of men reporting successful intercourse.
- Onset time - how quickly the drug starts working.
- Duration of effect - window during which intercourse is possible.
- Side‑effect profile - frequency and severity of common adverse events.
- Cost & insurance coverage - out‑of‑pocket price and eligibility for pharmaceutical benefits.
These benchmarks let you line up each medication side‑by‑side and see where the extra dose really shines-or falls short.

Overview of Popular Alternatives
Below is a snapshot of the main competitors in the PDE5 space. All are prescription drugs approved by the FDA and the Therapeutic Goods Administration (TGA) in Australia.
- Viagra (Sildenafil) an oral PDE5 inhibitor usually taken at 50 mg or 100 mg. Works within 30‑45 minutes; lasts 4‑6 hours.
- Stendra (Avanafil) the fastest‑acting PDE5 inhibitor, effective in as little as 15 minutes. Duration up to 12 hours.
- Levitra (Vardenafil) offers a slightly longer onset than Viagra and a 4‑5 hour window.
- Generic Tadalafil identical to Cialis but typically sold at lower price points. Available in 2.5 mg, 5 mg, 10 mg and 20 mg strengths.
Side‑Effect Profile Comparison
Medication | Headache | Flushing | Indigestion | Vision changes | Contraindications (major) |
---|---|---|---|---|---|
Cialis (10 mg) | 12 % | 9 % | 7 % | 1 % | Nitrate meds, severe heart disease |
Cialis Extra (20 mg) | 18 % | 14 % | 12 % | 2 % | Same as 10 mg, higher risk with nitrates |
Viagra (100 mg) | 16 % | 8 % | 9 % | 1 % | Nitrates, uncontrolled hypertension |
Stendra (200 mg) | 9 % | 7 % | 5 % | 0.5 % | Nitrates, certain eye conditions |
Levitra (20 mg) | 15 % | 10 % | 11 % | 1 % | Nitrates, severe liver impairment |
Notice how the 20 mg dose bumps up most side‑effect percentages by roughly 5‑7 points. The trade‑off is that a subset of men who didn’t respond to 10 mg achieve full rigidity with the higher dose.
Cost, Insurance, and Accessibility in Australia
Pricing can swing dramatically depending on brand, pharmacy, and whether you qualify for the Pharmaceutical Benefits Scheme (PBS). Rough estimates (2025 AUD) for a 30‑tablet pack:
- Standard Cialis (10 mg) - $180‑$220 (PBS subsidy may bring it to $85).
- Cialis Extra (20 mg) - $210‑$260 (PBS usually not listed, full price applies).
- Generic Tadalafil (10 mg) - $120‑$150 (often covered by PBS).
- Viagra (100 mg) - $170‑$210 (no PBS subsidy).
- Stendra (200 mg) - $250‑$300 (premium price, rarely subsidized).
- Levitra (20 mg) - $190‑$230 (limited PBS coverage).
If cost is a primary driver, the generic 10 mg version of tadalafil typically offers the best bang for the buck while still delivering the 36‑hour window.

Choosing the Right Option for Your Situation
Below is a quick decision guide. Read the question that matches your circumstances and follow the recommendation.
- Do you need a longer “window” for spontaneity? If yes, stay with any tadalafil formulation (10 mg or 20 mg) because they last up to 36 hours.
- Have you tried the 10 mg dose and still struggle? Consider stepping up to 20 mg, but discuss heart health with your GP first.
- Are you on nitrates or have uncontrolled hypertension? All PDE5 inhibitors, including the 20 mg dose, are contraindicated. Look into non‑PDE5 options such as vacuum devices or counseling.
- Is price the biggest barrier? Generic tadalafil 10 mg or daily low‑dose may be the most affordable route.
- Do you want the fastest onset? Stendra (Avanafil) can work in 15 minutes, making it the go‑to for last‑minute plans.
Always involve a qualified healthcare professional before changing dose or switching drugs. They can run a quick assessment of heart health, medication interactions, and any underlying conditions that could affect safety.
Practical Tips for Safe Use
- Take the tablet with water, not a full meal; heavy fatty foods can delay absorption. \n
- Avoid alcohol excess; it can worsen dizziness and lower blood pressure.
- If you experience a painful or prolonged erection (priapism) lasting more than 4 hours, seek emergency care.
- Store pills at room temperature, away from moisture and direct sunlight.
- Keep a list of all medications you take; share it with your prescribing doctor.
Frequently Asked Questions
Can I take Cialis Extra Dosage more than once a day?
No. Even the 20 mg tablet should not be taken more than once in a 24‑hour period. Doing so raises the risk of serious side effects like low blood pressure.
Is it safe to combine the 20 mg dosage with alcohol?
Moderate alcohol (one‑two drinks) is usually okay, but heavy drinking can intensify dizziness, headache, and blood‑pressure drops. Keep alcohol low‑key on pill days.
Do I need a prescription for the 20 mg strength?
Yes. In Australia, any dosage of tadalafil above 5 mg requires a doctor's prescription because of the higher side‑effect potential.
How does the effectiveness of 20 mg compare to the 10 mg version?
Clinical trials show an extra 5‑10 % increase in successful intercourse for men who did not achieve results with 10 mg. The benefit varies per individual.
Are there any long‑term health risks with taking the higher dose?
Long‑term data are limited, but the main concerns revolve around cardiovascular stress in men with pre‑existing heart disease. Regular check‑ups are advisable.
By weighing effectiveness, side effects, cost, and personal health, you can pinpoint whether the 20 mg Cialis pill or another ED medication fits best. Remember, the right choice is the one that keeps both performance and safety in balance.
Comments
It is deeply unsettling how the pharmaceutical conglomerates, cloaked in glossy marketing, push ever‑higher doses of tadalafil onto unsuspecting patients while conveniently glossing over the cumulative burden on the cardiovascular system. The surge in prescriptions for the 20 mg formulation is not merely a response to clinical need, but a calculated move to increase profit margins, leveraging the fear of under‑performance that many men experience with the standard 10 mg dose. Every extra milligram translates into a larger paycheck for the drug manufacturers, and the regulatory agencies appear complicit by allowing such dosage escalations without demanding longitudinal safety data. The subtle shift from a modest, on‑demand tablet to a potent, semi‑daily high‑dose regimen fuels a culture of dependency that undermines personal responsibility. Moreover, the alleged “marginally higher chance of success” is statistically insignificant for the majority of users, yet it is advertised as a miracle cure for those who “didn't respond adequately.” By normalizing the extra dosage, the industry creates a false narrative that more is always better, ignoring the principle of the lowest effective dose. The side‑effect profile, inflated by five to seven percent for each adverse event, is downplayed, and patients are rarely warned about the heightened risk of severe hypotension when combined with nitrates. In a society already plagued by over‑medicalization, pushing the 20 mg option without robust evidence is morally reprehensible. One must ask why the data supporting the superiority of the higher dose is buried in obscure journal supplements, accessible only to those who can afford expensive subscriptions. The covert messaging exploits men's insecurities about sexual performance, weaponizing vulnerability for commercial gain. Ethical physicians should resist this pressure and counsel patients on lifestyle modifications before defaulting to pharmacological escalation. The cost disparity is another glaring injustice; while a generic 10 mg tablet can be subsidized, the premium 20 mg version remains largely excluded from public health schemes, effectively penalizing lower‑income individuals. The hidden agenda is clear: create a tiered market where those with deeper pockets receive the “enhanced” version, while the rest are left to manage suboptimal outcomes. This stratification deepens socioeconomic health gaps and erodes trust in the medical establishment. Ultimately, the pursuit of profit must not eclipse the duty to protect patients from unnecessary exposure to higher drug concentrations and their attendant risks.
