Key advantages of Tadalafil
- Long duration of activity of upto 36 hours

Tadalafil is a PDE-5 (phosphodiesterase type 5) Phosphodiesterase Type inhibitor. Its mechanism of action is by dilating the blood vessels within the penis. During sexual arousal (sexual stimuli) process, a nucleotide called cGMP is released in your bloodstream. This relaxes the blood vessels within the penis, this in turn leads to an increase in blood flow and volume within the penis helping to achieve and sustain an erection.
To return to a non-erect state, cGMP is broken down by the naturally occurring enzyme PDE-5, this reduces blood flow in the penis. Tadalafil works by blocking the actions of PDE-5, this maintains a larger volume of cGMP within the bloodstream resulting in the effect of prolonging the erection (achieve a fuller and firmer erection). Tadalafil can start working within 30minutes after use and can last for upto 36hours. This however does not mean the user will maintain an erection for 36 hours, Tadalafil only works when the user is aroused (encounters sexual stimulation).
Tadalafil can last up to 36 hours, this is not for every individual as factors such as weight, existing medical conditions and use of other medications will have an effect on duration. The diagram below shows the typical concentration of Tadalafil in the blood, peak concentration is reached between 5-6 hours.
The dosage that is prescribed depends on many factors such as age, medical conditions and other medications being taken. The severity of your Erectile Dysfunction (impotence) is also a key consideration too.
Our doctors will take these and other factors into account when prescribing the treatment.

Some men who are taking Tadalafil regularly (more than 2 times a week) are suited to a daily lower dose tablet (either 2.5mg or 5mg).
This keeps the levels of tadalafil constant in the body. Tadalafil is the only ED medication available in the daily dosage form.
Some people refer to Tadalafil as the ‘weekend’ pill. The effects of Tadalafil can last for 36 hours. This would help you to achieve an erection across a 2/3 day period. Therefore, if you took it on Friday evening, the medication would be effective for the whole weekend. It is only effective when there is sexual stimulation or sexual activity.
Tadalafil should only be taken to treat the symptoms of ED.
Drinking one or two units of alcohol with Tadalafil should not be a problem. Excess alcohol usage will lead to poor outcomes from this treatment.
Please note, Tadalafil can cause your blood pressure to be lowered, this is also the effect alcohol has on your blood pressure therefore this combined effect could be dangerous.
