Tadalafil comes in doses ranging from 2.5mg all the way to 20mg. Tadalafil 10mg and tadalafil 20mg are ideal options for men who don't want to take a tablet every time they have sex. This option involves some planning – as you need to take a tablet at least 30 minutes before you want to have sex – but the effects can last for up to 36 hours, which is why it’s sometimes known as “the weekender”. Tadalafil 2.5mg and tadalafil 5mg (known as Tadalafil Daily) are more ideal for those who have sex frequently, such as those who are in long term relationships. This is because Tadalafil Daily keeps your body topped up with a small but constant supply of tadalafil at all times, allowing you to get an erection whenever you need one. This gives you the ability to enjoy more spontaneous sex without needing to time when to take a tablet, which is why many men prefer Tadalafil Daily over other erectile dysfunction treatments.
