CIALIS is a treatment for adult men with erectile dysfunction. This is when a man cannot get, or keep a hard, erect penis suitable for sexual activity. CIALIS has been shown to significantly improve the ability of obtaining a hard erect penis suitable for sexual activity.
CIALIS contains the active substance tadalafil which belongs to a group of medicines called phosphodiesterase type 5 inhibitors. Following sexual stimulation CIALIS 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. CIALIS will not help you if you do not have erectile dysfunction.
It is important to note that CIALIS does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
Talk to your doctor before taking CIALIS.
Be aware that sexual activity carries a possible risk to patients with heart disease because it puts an extra strain on your heart. If you have a heart problem you should tell your doctor.
Before taking the tablets, tell your doctor if you have:
It is not known if CIALIS is effective in patients who have had:
If you experience sudden decrease or loss of vision or your vision is distorted, dimmed while you are taking CIALIS, stop taking CIALIS and contact your doctor immediately.
Decreased or sudden hearing loss has been noted in some patients taking tadalafil. Although it is not known if the event is directly related to tadalafil, if you experience decreased or sudden hearing loss, stop taking CIALIS and contact your doctor immediately.
CIALIS is not intended for use by women.
CIALIS is not intended for use by children and adolescents under the age of 18.
Tell your doctor if you are taking, have recently taken or might take any other medicines
Do not take CIALIS if you are already taking nitrates.
Some medicines may be affected by CIALIS or they may affect how well CIALIS will work. Tell your doctor or pharmacist if you are already taking:
Information on the effect of alcohol is in section 3. Grapefruit juice may affect how well CIALIS will work and should be taken with caution. Talk to your doctor for further information.
When dogs were treated there was reduced sperm development in the testes. A reduction in sperm was seen in some men. These effects are unlikely to lead to a lack of fertility.
Some men taking CIALIS in clinical studies have reported dizziness. Check carefully how you react to the tablets before driving or using machines.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
CIALIS 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 CIALIS tablet at least 30 minutes before sexual activity.
CIALIS may still be effective up to 36 hours after taking the tablet.
Do not take CIALIS more than once a day. CIALIS 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 CIALIS does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
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 CIALIS, avoid excessive drinking (blood alcohol level of 0.08 % or greater), since this may increase the risk of dizziness when standing up.
Contact your doctor. You may experience side effects described in section 4.
