CIALIS is used to treat:
- erectile dysfunction, also known as impotence, in men. This is when a man cannot get, or maintain, a hard erect penis suitable for sexual activity. 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 only treat
- erectile dysfunction if you are sexually aroused. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.
urinary symptoms associated with a common condition called benign prostatic hyperplasia. This is when the prostate gland gets bigger with age. Symptoms include difficulty in starting to pass urine, a feeling of not completely emptying the bladder and a more frequent need to pass urine even at night. CIALIS improves blood flow to, and relaxes the muscles of, the prostate and bladder which may reduce symptoms of benign prostatic hyperplasia.
Do not use CIALIS if:
- you are allergic to tadalafil, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can use this medicine
- you are currently taking any nitrates, medicines used for the treatment of angina ("chest pain") or other heart conditions. CIALIS has been shown to increase the effects of these medicines.
- if you use recreational drugs called "poppers" or "amyl" like amyl nitrite and butyl nitrite that are normally taken through inhalation
- if you use guanylate cyclase stimulators such as riociguat, used to treat pulmonary arterial hypotension
- if you have heart or blood vessel problems that make sexual intercourse inadvisable. Sexual activity carries a possible risk to patients with a heart condition because it puts extra strain on the heart
- if you have heart problems such as angina, arrhythmias (change in rhythm or rate of heart beat), heart failure
- if you have suffered a heart attack in the last 3 months
- if you have suffered a stroke in the last 6 months
- if your blood pressure is unusually high or low or is not effectively treated
- if you have vision loss in one eye because of non-arteritic interior ischaemic optic neuropathy (NAION).
