WHAT CIALIS IS AND WHAT IT IS USED FOR
CIALIS is a treatment for men with erectile dysfunction. This is when a man cannot get, or keep a
hard, erect penis suitable for sexual activity.
CIALIS 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

CIALIS has been shown to increase the effects of these medicines. If you are taking any form of nitrate or are unsure tell your doctor. if you have serious heart disease or have had a recent heart attack. - if you have low blood pressure or uncontrolled high blood pressure. - if you have ever had loss of vision because of non-arteritic anterior ischemic optic neuropathy (NAION), a condition sometimes described as “stroke of the eye”.
Take special care with 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.

talk to your doctor before you take the medicine:
You have sickle cell anaemia (an abnormality of red blood cells), multiple myeloma (cancer of the bone marrow), leukaemia (cancer of the blood cells) or any deformation of your penis.

Using other medicines

medicines obtained without a prescription, because they might interact.
This is particulary important if you are treated with nitrates as you should not take CIALIS if you are
taking these medicines.
A type of medicine called an alpha blocker is sometimes used to treat high blood pressure and
enlarged prostate. Tell your doctor if you are being treated for either of these conditions or if you take
other medicines to treat high blood pressure.

protease inhibitors for treatment of HIV) the frequency of side effects might increase.
Do not take CIALIS with other medicines if your doctor tells you that you may not.
You should not use CIALIS together with any other treatments for erectile dysfunction.

HOW TO TAKE CIALIS
Always take CIALIS exactly as your doctor has told you. You should check with your doctor or
pharmacist if you are not sure.
Once a day dosing of CIALIS may be useful to men who anticipate having sexual activity two or more
times per week. The recommended dose is one 5 mg tablet taken once a day at approximately the same
time of the day. Your doctor may adjust the dose to 2.5 mg based on your response to CIALIS.
CIALIS tablets are for oral use. Swallow the tablet whole with some water. You may take CIALIS
with or without food.
When taken once a day CIALIS allows you to obtain an erection, when sexually stimulated, at any
time point during the 24 hours of the day. 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. Drinking alcohol may temporarily lower
your blood pressure. If you have taken or are planning to take CIALIS, avoid excessive drinking

POSSIBLE SIDE EFFECTS
Like all medicines, CIALIS can cause side effects, although not everybody gets them. These effects are normally mild to moderate in nature. In this leaflet, when a side effect is described as “very common” this means that it has been reported in at least 1 in 10 patients taking the medicine. When a side effect is described as “common” this means that it has been reported in more than 1 in every 100 patients but less than 1 in every 10 patients. When a side effect is described as “uncommon”, this means it has been reported in more than 1 in every 1,000 patients, but less than 1 in every 100 patients. When a side effect is described as “rare”, this means it has been reported in more than 1 in every 10,000 patients, but less than 1 in every 1,000 patients. Very commonly reported side effects in patients taking CIALIS were headache. Commonly reported side effects in patients taking CIALIS include back pain, muscle aches, facial flushing, nasal congestion, dizziness, and indigestion. Uncommon side effects are allergic reactions including rashes, abdominal pain, reflux, blurred vision, eye pain, increased sweating, pounding heartbeat sensation, a fast heart rate, high blood pressure, low blood pressure and chest pain. In case of chest pain occurring during or after sexual activity you should NOT use nitrates but you should seek immediate medical assistance. Rare side effects in patients taking CIALIS include fainting, seizures and passing memory loss, swelling of the eyelids, red eyes, sudden decrease or loss of hearing, hives and nose bleeds.

CIALIS. If you have such an erection, which lasts continuously for more than 4 hours, you should
contact a doctor immediately.
Heart attack and stroke have also been reported rarely in men taking CIALIS. Most, but not all of
these men had known heart problems before taking this medicine. It is not possible to determine
whether these events were directly related to CIALIS.
Partial, sudden, temporary, or permanent decrease or loss of vision in one or both eyes has been rarely
Some additional side effects have been reported in men taking CIALIS at an estimated frequency of
rare that were not seen in clinical trials. These include migraine, swelling of the face, serious skin
rashes some disorders affecting blood flow to the eyes, irregular heartbeats, angina and sudden cardiac
