How to take Tadalafil 20mg tablets

The maximum dose of Tadalafil is one 20mg tablet per day. Do not repeat the dose or take any other ED treatments within 36 hours of your initial dose.

Tadalafil 20mg tablets are designed to be taken on an ‘as required' basis — only take them if you expect that you’re going to need help achieving an erection within the next 36 hours.

Tadalafil tablets may be taken either with or without food. Swallow the tablet whole and if needed, use water to wash it down.

Always avoid or limit the use of alcohol while using Tadalafil.

Which strength of Tadalafil should I choose?

Tadalafil tablets are available in a variety of different strengths, including 2.5mg, 5mg, 10mg, and 20mg. The strength you choose will depend on how you want to use it — the two main ways to take Tadalafil are as an ‘as required’ dosage or as a continuous daily dosage.

• Tadalafil 10mg & 20mg (the ‘as required’ dose) — the recommended starting dose for Tadalafil as an ‘as required’ medication is 10mg, taken at least 30 minutes before sexual activity. From there, the dose may be increased to 20mg or decreased to 5mg, depending on how your body reacts. It's important to note that Tadalafil should not be taken more than once per day.

Tadalafil's 10mg and 20mg strengths are formulated for occasional use and can remain active for up to 36 hours, making them an excellent choice if you engage in sexual activity less than twice a week or cannot predict when you'll next have sex. These strengths provide you with the flexibility to achieve an erection only when you need it, without requiring daily medication.

• Tadalafil 2.5mg & 5mg (Tadalafil Daily) — For individuals who engage in sexual activity more frequently or want to be ready at all times, Tadalafil is also available as a continuous daily medication.

The recommended starting dose for daily Tadalafil is 2.5mg, which can be increased to 5mg based on the individual's response. This method of dosing is ideal for individuals who have sex at least twice a week and want to be able to achieve an erection at any time.
