Is a stronger tablet more effective?

Only if a standard dose was genuinely insufficient. These medicines have a ceiling: past it you add side effects faster than effect, which is why 100 mg sildenafil and 20 mg tadalafil are the registered maximums.

Does a higher dose last longer?

No. Duration is a property of the molecule, not the dose — sildenafil covers 4–5 hours at any strength, tadalafil up to 36.

When is a high-strength tablet reasonable?

When lower doses have been tried properly — right timing, no heavy meal, limited alcohol, several attempts — and demonstrably fell short, with medical advice.

What changes at a higher dose?

Side effects scale with dose: headache, flushing, blocked nose, indigestion and dizziness all become more likely, as does the drop in blood pressure.

What must I never combine them with?

Nitrates and poppers, absolutely. Care is also needed with alpha-blockers and other blood-pressure medicines, more so at high doses.

Strong Dose ED Meds

Erectile Dysfunction Strong Dose

All stronger dosage erectile dysfunction medications are displayed on this page. Suited to men who require extra help with their ED. The medications below are of equivalent strength to each other (notwithstanding some contain 150mg and others have 40mg of active ingredient).

Some men who suffer from ED, find that after taking standard strength medications such as Viagra 100mg or Cialis 20mg, their condition does not improve much and they are still unable to get a satisfactory erection to have sex. Men with severe erectile dysfunction may benefit from a stronger dose medication such as 150mg Viagra or 40mg Cialis.

Other men get confused between the strengths of Viagra 150mg and Cialis 40mg, thinking one medication is stronger than the other. Both medications, despite the size of the pill, are exactly the same strength despite having different quantities of active ingredient. This is due to different formulations of each active ingredient that cause a similar result. Both medications stimulate blood flow in your body and help to produce a firmer erection, however 40mg generic Cialis lasts for up to 36 hours versus 5 hours for 150mg generic Viagra.

The condition of ED can become more severe over time depending on your age and health. Your medication may have to be adjusted accordingly to a stronger dosage so that it can still be effective for you.

At OzPills we offer our customers a convenient selection of medications in different combinations. In our popular Duo Pro Pack, we offer a selection of ten generic Viagra 150mg pills and ten generic Cialis 40mg. That way, you will have medications that prepare you for sex with strong generic Viagra or for longer duration of action, strong generic Cialis. Another popular combination is our Combo Pro Pack, which includes ten generic Viagra 150mg, ten generic Cialis 40mg and ten generic Levitra 40mg pills. As generic Levitra is a more recently developed medication than the other two, it has been refined to have fewer side effects, while still being very effective. Fewer side effects is the most apt benefit of generic Levitra Professional 40mg which is also our strongest and most reliable erectile dysfunction medication.

A study conducted by the Australian Centre for Sexual Health at St Luke’s Hospital in Sydney, set out to test the effectiveness of higher dosages of Viagra for the treatment of men with chronic ED. Over 50 men were selected for the clinical trial, all of whom were unable to achieve an erection after taking a standard 100mg Viagra dose. The participants were given increasing strengths of up to 200mg of Viagra over a period of one month.

After the treatment concluded, the subjects of the study were evaluated to see how much the firmness of their erections had improved with higher medication dosages. The results showed that the men who took 150mg of Viagra showed an improvement of 46%, while the men who took 200mg of Viagra, showed a 69% improvement.

However, up to 60% of the men in the study experienced some side effects after taking the maximum dosage of Viagra 200mg. Those side effects included dizziness, nasal congestion, blurred vision and headaches. The conclusion of the clinical trial was that higher dosages of Viagra did improve the erections of those men with severe ED. Those side effects increased in severity with higher medication dosages. That is why at OzPills we do not sell dosages of generic Viagra higher than 150mg.

The honest case for — and against — a stronger dose

Higher strengths have a real place, and it is narrower than the page count on the internet suggests. These medicines have a ceiling: past a certain dose the extra benefit is small and inconsistent while the side effects keep climbing. That is why 100 mg sildenafil and 20 mg tadalafil are the registered maximums, and why everything on this page sits above what a pharmacy would dispense.

A stronger tablet is reasonable when a standard dose has been tried properly and genuinely fell short. "Properly" means the right timing, no heavy fatty meal, no more than a drink or two, and two or three attempts — because a single disappointing evening usually says more about the evening.

What actually changes at a higher dose

What people expect	What actually happens
It lasts longer	No — duration belongs to the molecule, not the dose. Sildenafil stays 4–5 hours; tadalafil stays up to 36
It works when a normal dose did nothing	Sometimes — but if a full dose does nothing at all, the cause often is not dose-related
Side effects are the same	No — headache, flushing, blocked nose, indigestion and dizziness all become more likely
Blood pressure effect is the same	No — it scales too, which matters with blood-pressure medicines or an alpha-blocker

The sensible sequence

Standard dose, taken correctly, judged over two or three attempts.
If it helped but not enough, the standard maximum — 100 mg sildenafil or 20 mg tadalafil.
Only then a higher strength, and preferably after a conversation with a doctor about why the maximum was not enough.
If nothing works at a full dose, that is a medical question rather than a bigger tablet: blood pressure, diabetes, medication side effects and hormonal causes all produce exactly this pattern.

The rules do not relax at higher strengths

Never with nitrates or poppers. Extra care with alpha-blockers and other blood-pressure medicines, because the pressure drop is larger here. One dose in 24 hours — more so, not less, with a high-strength tablet. An erection lasting more than four hours needs urgent medical attention. See ED pills and other medicines for the full map, and remember these are all Schedule 4 medicines in Australia.
