Vidalista is a range of tadalafil products manufactured by Centurion Laboratories. Two of the most searched strengths in the UK are Vidalista 60 and Vidalista 80 – containing 60mg and 80mg of tadalafil respectively. To understand what these doses mean requires understanding how tadalafil is used clinically in the UK and how these figures relate to the licensed dose range.

What tadalafil is and how it works

Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor – the same drug class as sildenafil. It works by blocking the PDE5 enzyme, allowing cyclic GMP to accumulate in penile smooth muscle tissue, which supports blood flow during sexual arousal. Like sildenafil, it requires sexual arousal to produce its effect.

Tadalafil’s most distinctive clinical feature is its duration of action. While sildenafil’s effect lasts approximately four to six hours, tadalafil’s half-life is around 17.5 hours, and its effect is typically described as lasting up to 36 hours. This extended window makes it a preferred option for men who do not want to plan sexual activity around a narrow medication window.

Tadalafil is also approved in the UK for two additional indications beyond erectile dysfunction: pulmonary arterial hypertension and benign prostatic hyperplasia (enlarged prostate). The doses used for these conditions differ from those used for ED.

Licensed tadalafil doses in the UK

This is the essential reference point for understanding Vidalista 60 and 80. In the UK, tadalafil is licensed by the MHRA for erectile dysfunction at the following doses:

10mg – the standard starting dose, taken as needed before sexual activity
20mg – the maximum licensed on-demand dose for ED
2.5mg and 5mg – approved for daily use, providing continuous low-level effect without the need for timing

The maximum licensed on-demand dose of tadalafil for erectile dysfunction in the UK is 20mg. This is the dose that has been evaluated by the MHRA for safety and efficacy in the UK adult population.

Vidalista 60mg: three times the licensed maximum

Vidalista 60mg contains 60mg of tadalafil – three times the maximum licensed on-demand dose approved by the MHRA for erectile dysfunction. This dose has not been evaluated in the regulatory process that establishes safety and efficacy benchmarks for UK adults.

Pharmacologically, a higher dose of tadalafil produces stronger and potentially longer-lasting PDE5 inhibition. However, the dose-response relationship has a ceiling – beyond the licensed range, the incremental therapeutic benefit decreases while side effect risk continues to increase.

Tadalafil’s extended half-life amplifies this concern. At licensed doses, tadalafil remains active for up to 36 hours. At 60mg, a supratherapeutic dose remains in the body at meaningful concentrations for an extended period – increasing the window during which interactions with other substances, including alcohol and nitrate medications, can occur.

Vidalista 80mg: four times the licensed maximum

Vidalista 80mg contains 80mg of tadalafil – four times the maximum licensed dose for erectile dysfunction in the UK. The same concerns that apply to Vidalista 60mg apply here with greater intensity.

Side effects at licensed doses and how they scale

The side effects associated with tadalafil at licensed doses include:

Headache – one of the most commonly reported
Back pain and muscle aches – more commonly associated with tadalafil than sildenafil, thought to relate to PDE11 inhibition in muscle tissue
Facial flushing
Indigestion and nasal congestion
Dizziness and orthostatic hypotension

At doses above the licensed range, these effects become more pronounced. Back pain and muscle aches – already more associated with tadalafil than sildenafil at standard doses – are likely to be more significant at 60mg and 80mg. The blood pressure effects, particularly when combined with alcohol or antihypertensive medications, become more clinically significant.

Why the dose difference between Vidalista and licensed tadalafil is so large

The question of why Vidalista products come in doses so far above the licensed range – rather than simply replicating the 10mg and 20mg licensed doses – reflects market positioning rather than clinical reasoning. The perception that a higher number means a stronger or more reliable product is commercially exploitable, even when pharmacological reality is more nuanced.

The licensed maximum dose for ED reflects the point at which the benefit-risk assessment was considered most favourable across the population studied. It is not an arbitrary conservative limit – it is the output of clinical trials that included dose-escalation studies.

Tadalafil for daily use versus on-demand use

One of the distinctive features of tadalafil’s pharmacology – its long half-life – makes it suitable for daily low-dose use. At 2.5mg or 5mg daily, tadalafil maintains a consistent blood level that provides ongoing PDE5 inhibition without the peaks and troughs of on-demand dosing. This approach suits men who have frequent sexual activity and prefer not to take a dose in anticipation of any specific occasion.

This daily-use option is only available through licensed products at licensed doses. It is not an approach that can be safely applied to supratherapeutic doses, where the accumulation effect of daily dosing would be clinically unmanageable.

Frequently asked questions

Why do some men report that Vidalista 60 works when lower tadalafil doses did not?

Non-response to licensed tadalafil is most appropriately addressed through clinical review, not dose escalation to unlicensed products. Possible reasons for reduced efficacy at licensed doses include underlying vascular or hormonal conditions, incorrect use timing, or alcohol interaction. A GP is the right resource to assess this.

Is Vidalista the same as Cialis?

Both contain tadalafil as the active ingredient. Cialis is the branded licensed product manufactured by Eli Lilly, approved by the MHRA. Vidalista is manufactured by Centurion Laboratories and is not licensed in the UK. The active compound is the same; the regulatory status and quality assurance framework are not.

Is there a maximum safe dose of tadalafil?

The maximum dose assessed and approved by the MHRA for ED is 20mg as needed. Beyond this, there is no established safety profile from regulatory-standard clinical trials for UK adults. Doses above 20mg carry increasing side effect risk without a proportional increase in established therapeutic benefit.

Can a GP prescribe Vidalista?

No. GPs can only prescribe licensed medicines within their approved dose ranges. A GP can prescribe tadalafil at licensed doses – 10mg or 20mg on demand, or 2.5mg or 5mg for daily use – but not Vidalista or any other unlicensed tadalafil product.
