Consumer Medicine Information
 

NOTICE: This Consumer Medicine Information (CMI) is intended for persons living in Australia. This page contains answers to some common questions about Cialis. It does not contain all the information that is known about Cialis. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits. Your doctor has weighed the risk of you using this medicine against the benefits he/she expects it will have for you. If you have any concerns about using this medicine, ask your doctor or pharmacist. Bookmark or print this page, you may need to read it again.

What CIALIS is used for

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.
Your doctor may have prescribed you CIALIS to treat either, or both of these conditions.
Ask your doctor if you have any questions about why CIALIS has been prescribed for you.
Your doctor may have prescribed it for another reason. CIALIS is available only with a doctor's prescription.
CIALIS is not intended for use by women or by children under the age of 18 years.
The active ingredient in CIALIS tablets, tadalafil, belongs to a group of medicines called phosphodiesterase type 5 inhibitors.

Before you take CIALIS

When you must not take it

Do not take CIALIS if you are currently taking any nitrates or amyl nitrite.
Nitrates are 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 are taking any form of nitrate or are unsure talk to your doctor.
Do not take CIALIS:
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 (changes in rhythm or rate of heart beat), heart failure.
if you have suffered a heart attack in the last 3 months
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)
if you use recreational drugs called "poppers" or "amyl" like amyl nitrite and butyl nitrite that are normally taken through inhalation
Do not take CIALIS if you have an allergy to:
any of the ingredients listed at the end of this leaflet
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.
Do not take this medicine after the expiry date printed on the pack.
If it has expired, return it to your pharmacist for disposal.

Other PDE5 inhibitors such as sildenafil used to treat erectile dysfunction or pulmonary arterial hypertension (high blood pressure in the blood vessels in the lungs)
These medicines may be affected by CIALIS or may affect how well it works. You may need different amounts of your medicines or you may need to take different medicines.
You should not take CIALIS together with any other treatments for erectile dysfunction.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.

How to take CIALIS

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
For Erectile Dysfunction
CIALIS can be taken as either on-demand dosing or once-a-day dosing.
CIALIS on-demand (10 mg and 20 mg) is intended for use prior to anticipated sexual activity and is not for continuous daily use.
CIALIS once-a-day (5 mg) is for patients who anticipate frequent use of CIALIS (i.e. at least twice weekly). Your Doctor can advise on the appropriateness of once-a-day treatment. 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. Do not take once-a-day dosing and on-demand dosing concurrently.
For urinary symptoms associated with Benign Prostate Hyperplasia
CIALIS once-a-day (5mg) is taken daily. It may take a week to notice an improvement and several weeks before a full effect on urinary symptoms such as; urinating too frequently during the day or at night, the need to urinate being too urgent, or too soon after relieving your bladder. CIALIS must be taken daily to maintain effect.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

How much to take

You should not take CIALIS more than once a day. 
Always take CIALIS exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
ON-DEMAND DOSING FOR ERECTILE DYSFUNCTION
The maximum recommended dose of CIALIS is one 20 mg tablet taken before sexual activity.
If you have kidney disease, the recommended dose of CIALIS is one 10 mg tablet. This dose may be increased up to 20 mg. For patients with severe renal impairment 10 mg is the maximum recommended dose.
If you have liver disease, the recommended dose of CIALIS is one 10mg tablet. Patients with severe hepatic impairment should follow their doctor's advice.
No special dosing consideration is needed for the elderly or people with diabetes.
ONCE-A-DAY DOSING FOR ERECTILE DYSFUNCTION AND/OR URINARY SYMPTOMS ASSOCIATED WITH BENIGN PROSTATE HYPERPLASIA
The recommended dose of CIALIS is one 5 mg tablet taken once per day.
Dosage adjustments are not required in patients with kidney disease, unless you have severe renal impairment. Once-a-day dosing of CIALIS is not recommended in patients with severe renal impairment.
Patients with liver disease should follow their doctor's advice. Once-a-day dosing of CIALIS is not recommended in patients with severe hepatic impairment.
No special dosing consideration is needed for the elderly or people with diabetes.

How to take it

Swallow one tablet whole with a full glass of water.

When to take it

CIALIS can be taken with or without food or alcohol. However, drinking alcohol may affect your ability to get an erection, so avoid excessive drinking.
ON-DEMAND DOSING FOR ERECTILE DYSFUNCTION
CIALIS (10 mg or 20 mg) should be taken at least 30-60 minutes prior to anticipated sexual activity.
The amount of time CIALIS takes to work varies from person to person. In some men CIALIS can work as early as 16 minutes after taking the tablet but it is recommended that you allow 1 hour the first time you take it. CIALIS has been proven to be effective for up to 36 hours. This means you can take CIALIS and it will allow you to obtain an erection when sexually stimulated, at any time during the 36 hours after taking it. Sometimes if you're feeling anxious or nervous you may not respond to the first tablet. Don't give up, it may take a few doses before you get the full benefit of CIALIS.
ONCE-A-DAY DOSING FOR ERECTILE DYSFUNCTION AND/OR URINARY SYMPTOMS ASSOCIATED WITH BENIGN PROSTATE HYPERPLASIA
Cialis 5 mg should be taken daily at approximately the same time of day. CIALIS must be taken daily to maintain effect.
If you have any questions about taking CIALIS, ask your doctor or pharmacist.

If you take too much (overdose)

Immediately telephone your doctor or the Australian Poisons Information Centre (telephone 13 11 26) or the New Zealand National Poisons Centre (0800 POISON or 0800 764 766), or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much CIALIS.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Symptoms of an overdose may include headache, dyspepsia (indigestion), back pain, muscular aches, nasal congestion and facial flushing.
