What is Tadalafil and how does it work?
Tadalafil is classed as a 'PDE5 inhibitor' and is a prescription only medication in the UK. It is licenced for men with erectile dysfunction (ED). ED is defined as a condition where a man cannot get or maintain a hard, erect penis suitable for sexual activity.
Tadalafil has been shown in clinical studies to significantly improve the ability to obtain a hard erection suitable for sexual activity for most men with ED. With sexual stimulation, Tadalafil works by helping the blood vessels in your penis to relax and open, allowing a good flow of blood into the penis. The result of which is a long lasting and firm erection.
Tadalafil will not help you if you do not have ED. It is important to note that Tadalafil does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay to increase arousal as usual, just as you would if you were not taking medicine for ED.
How do I take Tadalafil?
Tadalafil should be taken at least 30 minutes before sex. The recommended starting dose is 10 mg Tadalafil which can be taken with or without food. If 10mg Tadalafil is not effective for you, then after consulting with your doctor, you may be recommended the higher dose of 20mg Tadalafil. Daily Tadalafil is ideal for men who have sex three times a week or more, and who want to enjoy spontaneous sex that does not have to be planned around medication. Daily Tadalafil comes in two doses, 2.5mg or 5mg.
Can I take Tadalafil with alcohol?
Avoid taking Tadalafil with more than one or two units of alcohol, as this can limit its effectiveness. Eating a meal before taking Tadalafil should not delay the positive effects of the medicine.
What are the side effects of Tadalafil?
Side effects are uncommon but can include nausea, vomiting, diarrhoea and an allergic rash. It can also cause facial flushing, headache and rarely back-pain. There are some rare, more serious side effects (as with any medicine) and you should read the manufacturer’s leaflet that comes with the medication before taking it.
If Tadalafil doesn’t work for you the first time it is used, it could be more effective the next time. We advise that any erectile dysfunction medicine should be tried at on eight separate occasions before increasing the dose or switching to a different agent as there is good evidence for a cumulative effect.
