Before you start the treatment you must read the manufacturers leaflet contained with the medication. This contains more information about the medication and the potential side effects.
Tadalafil prevents the action of a chemical called phosphodiesterase type 5 in your body, helping to widen the blood vessels improving the flow of blood to the penis after sexual stimulation. Tadalafil helps to maintain an erection. Cialis is a branded version of tadalafil.
Tadalafil can be taken in two ways:
- Before sexual activity. It is available in two strengths for this purpose; 10mg and 20mg tablets. These tablets are not suitable for continuous daily use. You should take one tablet at least half an hour before you plan to have sex. Tadalafil may still be effective up to 36 hours after taking the 10mg or 20mg strength tablet. Do not take more than one dose in 24 hours. If tadalafil 10mg does not produce an adequate effect then 20 mg might be tried.
- Continuous daily use. There are two strengths available for this purpose; 2.5mg and 5mg tablets. Take one tablet every day at the same time of day. This can be used in men who anticipate a frequent use of tadalafil (at least twice weekly) based on patient choice. The lowest dose should be started and increased if the effect is not adequate.
How to take tadalafil
Tadalafil can be taken either with or without food. Swallow the tablet with a drink of water.
Do not drink grapefruit juice with tadalafil because there is a chemical in grapefruit juice which can increase the levels of tadalafil in your bloodstream, making side-effects more likely.
Tadalafil will not cause an erection unless you are sexually aroused, therefore you will still need to engage in foreplay.
Drinking too much alcohol before taking tadalafil can reduce your ability to get an erection. Only drink in moderation to ensure maximum benefit from the medication.
Do not drive or operate machinery if you develop any dizziness or visual changes such as blurred vision or colour distortion.
When starting tadalafil for the first time it is best to start on the lowest dose for the method in which you have chosen to take it. That is, 10mg if to be taken as and when needed before sexual activity and the 2.5mg dose if taken continuously on a daily basis. You can then judge whether this dose is adequate and discuss this with your doctor.
If you are using any other products or taking any other medicines to treat erectile dysfunction then you should not take tadalafil.
Never give your medication to other people even if their condition appears to be the same as yours.
