    How to take Tadalafil

    Take one tablet at least 30 minutes before sex. Effects can last for up to 36 hours. Never take more than one tablet within 36 hours. Alcohol will limit Tadalafil's effectiveness. Do not combine Tadalafil with other ED medicines.

    The standard dose is 10mg. Depending on your age, height and weight, the cause and the severity of your ED, you may be prescribed a higher dose of 20mg. Dosage does not affect how quickly or for how long the treatment works.

    Higher doses come with an increased chance of developing side effects. 

    How does Tadalafil work?

    Tadalafil's active ingredient (tadalafil) increases blood flow to the penis. It enables a firmer, longer-lasting erection if you are sexually aroused.

    The treatment will not resolve the underlying physical cause of your ED or increase your sexual desire.

    How effective is Tadalafil?

    Tadalafil treats ED in 80% of cases. If you have drunk more than 1-2 units of alcohol, you may find Tadalafil is less effective. Food does not impact how Tadalafil works.

    We advise trying an ED treatment 8 times before giving up, considering a higher dose, or seeking an alternative.

    How long does Tadalafil take to work?  

    It usually takes 30-60 minutes for Tadalafil to start working. But, don’t forget you will only see the effects if you’re sexually aroused. Tadalafil can last for up to 36 hours.

      Does Tadalafil help with enlarged prostate?

      Why is Tadalafil known as the 'weekend' pill?

      You might hear or see people referring to Tadalafil as the ‘weekend’ pill.
