Consumer Medicine Information (CMI)
This leaflet provides important information about using CIALIS. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about using CIALIS.
Where to find information in this leaflet:
1. Why am I using CIALIS?
CIALIS contains the active ingredient tadalafil. CIALIS belongs to a group of medicines called phosphodiesterase type 5 inhibitors.
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.
2. What should I know before I use CIALIS?
Warnings
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).
Check with your doctor if you have or have had:
liver or kidney problems
heart problems or if you have had a heart attack
blood vessel problems
sickle cell anaemia (an abnormality or red blood cells)
multiple myeloma (cancer of the bone marrow)
leukaemia (cancer of the blood cells)
any deformation of the penis (such as angulation, cavernosal fibrosis or Peyronie's
disease)
sudden decrease in vision, loss of vision, distorted vision and/or dimmed vision affecting
one or both eyes. If you experience any of these while you are taking CIALIS, stop
taking CIALIS and contact your doctor immediately.
During treatment, you may be at risk of developing certain side effects. It is important
you understand these risks and how to monitor for them. See additional information

4. How do I use CIALIS?
For Erectile Dysfunction:
CIALIS can be taken as either on-demand dosing or once-a-day dosing:
CIALIS on-demand (10 mg or 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
When taking CIALIS once-a-day (5 mg), it may take up to 1 week for a full effect on
erectile dysfunction.
For urinary symptoms associated with benign prostate hyperplasia
CIALIS once-a-day (5 mg) is taken daily. It may take up to a week to notice an improvement
and 1 month for 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.
How much to take
You should not take CIALIS more than once a day.
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 10 mg 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
dose 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
is not recommended in patients with severe hepatic impairment.

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 should be taken daily at approximately the same time of day
CIALIS must be taken daily to maintain effect.
