How does it work?
Following sexual stimulation Tadalafil works by helping the blood vessels in your penis to relax, allowing the flow of blood into your penis. The result of this is improved erectile function.
How is Tadalafil used?
Always use this medicine exactly as your doctor has told you. Check with your doctor, nurse or pharmacist if you are not sure.
Tadalafil tablets are for oral use in men only. Swallow the tablet whole with some water. The tablets can be taken with or without food.
The recommended starting dose is one 10 mg tablet before sexual activity. However, you have been given the dose of one 20mg tablet as your doctor has decided that the recommended dose of 10mg is too weak.
You may take a Tadalafil tablet at least 30 minutes before sexual activity. Tadalafil may still be effective up to 36 hours after taking the tablet.
Do not take Tadalafil more than once a day. Tadalafil 10 mg and 20 mg is intended for use prior to anticipated sexual activity and is not recommended for continuous daily use.
It is important to note that Tadalafil does not work if there is no sexual stimulation.
Drinking alcohol may affect your ability to get an erection and may temporarily lower your blood pressure. If you have taken or are planning to take Tadalafil, avoid excessive drinking (blood alcohol level of 0.08 % or greater), since this may increase the risk of dizziness when standing up.
