What is tadalafil?
Tadalafil is a medication used to treat erectile dysfunction. It has been shown to be very effective, and is generally safe to use. But, like any other medication, it needs to be taken as your doctor or pharmacist has instructed.
How does it work?
For an erection to take place, cells in your arteries normally release nitric oxide, which, via molecular messengers including cGMP, sends instructions to blood vessels to relax and open wide. This causes blood to flow into your penis, which causes an erection. It’s that arterial blood flow that causes the erection. After ejaculation, an enzyme called PDE-5 normally breaks down cGMP, which reverses that relaxation, allowing your erection to subside. Tadalafil, a PDE-5 inhibitor, helps maintain that erection instead.
Tadalafil does not cause an erection without sexual stimulation, and it does not increase your interest in sex. To get an erection, even having taken tadalafil, you still need to be sexually aroused.

The recommended dose
We offer tadalafil at two doses. The 10mg dose is taken 30 minutes before sexual intercourse, as needed, and the effects last around 36 hours. You should not take this every day. The 2.5mg dose is taken once daily. After taking it for three to five days, there is a constant level of tadalafil in your system which means you can have sex as spontaneously as you like. Taking tadalafil should not result in an erection for longer than you’d expect - a prolonged and painful erection (priapism) is a surgical emergency, and you should seek urgent medical attention should this happen.
