How to take tadalafil

If using 10mg or 20mg tadalafil, one tablet should be taken at least 30 minutes before you want to have sex.

If using the 5mg daily dose, one tablet should be taken every day around the same time. You do not have to plan when in the day you will have sex.

Tadalafil will only work if you are sexually aroused. You should only take 1 tadalafil tablet per 24 hours.

Can you take tadalafil with food or drink?

You can take tadalafil with or without food. Keep in mind that a heavy or greasy meal can slow down how fast tadalafil will work.

You should not drink a large amount of alcohol before you take tadalafil, as this can make it difficult for you to maintain an erection.

If you are unable to get an erection or keep an erection long enough with tadalafil, contact your doctor.

What dosage is tadalafil available in?

Tadalafil is available in 5mg, 10mg and 20mg dosage strengths. The dose you are prescribed by a doctor will depend on your medical history.

  • The lowest dose of tadalafil is 5mg. This is used as a once daily dose, and is recommended for men who have sex frequently (at least twice a week). 5 mg is taken every day.
  • The standard dose for tadalafil is 10mg.This is the usual starting dose if you have not used tadalafil before and you want to use it as and when it is needed.
  • The highest dose for tadalafil is 20mg. This might be used if the standard 10mg dose does not work for you.
