1.

What Tadalafil is and what it is used for

Tadalafil is used for treatment of erectile dysfucntion and /or urinary symptoms associated with benign
prostatic hyperplasia. Tadalafil contains the active substance tadalafil which belongs to a group of medicines
called phosphodiesterase type 5 inhibitors.
Erectile dysfunction
Tadalafil 2.5mg, 5 mg, 10 mg and 20 mg 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. Tadalafil has been shown to
significantly improve the ability of obtaining a hard erect penis suitable for sexual activity. Following sexual
stimulation Tadalafil 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. Tadalafil will not help you if you do not have
erectile dysfunction.
It is important to note that Tadalafil 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 (see section 3).
Benign prostatic hyperplasia
Tadalafil 5 mg is a treatment for 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 water, a
feeling of not completely emptying the bladder and a more frequent need to pass water even at night.
Tadalafil improves blood flow to, and relaxes the muscles of, the prostate and bladder which may reduce
symptoms of benign prostatic hyperplasia. Tadalafil has been shown to improve these urinary symptoms as
early as 1-2 weeks after starting treatment.

2.

What you need to know before you take Tadalafil

Do NOT take Tadalafil if you:
- are allergic to tadalafil or any of the other ingredients of this medicine (listed in section 6).
- are taking any form of organic nitrate or nitric oxide donors such as amyl nitrite. This is a group of
medicines (“nitrates”) used in the treatment of angina pectoris (“chest pain”). Tadalafil has been shown

-

to increase the effects of these medicines. If you are taking any form of nitrate or are unsure tell your
doctor (see section ‘‘Other medicines and Tadalafil’’).
have serious heart disease or recently had a heart attack within the last 90 days.
recently had a stroke within the last 6 months.
have low blood pressure or uncontrolled high blood pressure.
ever had loss of vision because of non-arteritic anterior ischemic optic neuropathy (NAION), a condition
described as “stroke of the eye”.

Warnings and precautions
Talk to your doctor before taking Tadalafil.
If you are being treated for erectile dysfunction
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.
If you are being treated for benign prostatic hyperplasia
Since benign prostatic hyperplasia and prostate cancer may have the same symptoms, your doctor will check
you for prostate cancer before starting treatment with Tadalafil for benign prostatic hyperplasia.
Tadalafil does NOT treat prostate cancer.
Before taking the tablets, tell your doctor if you have:
- sickle cell anaemia (an abnormality of red blood cells).
- multiple myeloma (cancer of the bone marrow).
- leukaemia (cancer of the blood cells).
- any deformation of your penis.
- a serious liver problem.
- a severe kidney problem.
It is not known if Tadalafil is effective in patients who have had:
- pelvic surgery.
- removal of all or part of the prostate gland in which nerves of the prostate are cut (radical nonnervesparing prostatectomy).
If you experience sudden decrease or loss of vision, STOP taking Tadalafil and contact your doctor
immediately.
Tadalafil is not intended for use by women.
Children and adolescents
Tadalafil is not intended for use by children and adolescents under the age of 18.
Other medicines and Tadalafil
Tell your doctor if you are taking, have recently taken or might take any other medicines
Do NOT take Tadalafil if you are already taking any form of nitrates (See ‘Do NOT take Tadalafil).
Some medicines may be affected by Tadalafil or they may affect how well Tadalafil will work. Tell your
doctor or pharmacist if you are already taking:
-

an alpha blocker (used to treat high blood pressure or urinary symptoms associated with benign prostatic
hyperplasia).
other medicines to treat high blood pressure.
a 5- alpha reductase inhibitor (used to treat benign prostatic hyperplasia).
medicines such as ketoconazole tablets (to treat fungal infections) and protease inhibitors for treatment
of AIDS or HIV infection.
phenobarbital, phenytoin and carbamazepine (anticonvulsant medicines).
rifampicin, erythromycin , clarithromycin or itraconazole.

-

other treatments for erectile dysfunction.

Tadalafil with drink and alcohol
Information on the effect of alcohol is in section 3. Grapefruit juice may affect how well Tadalafil will work
and should be taken with caution. Talk to your doctor for further information.
Fertility
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.
Driving and using machines
Some men taking Tadalafil in clinical studies have reported dizziness. Check carefully how you react
to the tablets before driving or using machines.
Tadalafil contains lactose
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before

How to take Tadalafil

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you
are not sure.
Tadalafil tablets are for oral use in men only. Swallow the tablet whole with some water. The tablets can be
taken with or without food.
Tadalafil 2.5 mg and 5 mg for erectile dysfunction
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 Tadalafil. This will be given as a
2.5mg tablet.
Do not take Tadalafil more than once a day.
Tadalafil 10 mg and 20 mg for erectile dysfunction
The recommended starting dose is one 10 mg tablet before sexual activity. If the effect of this dose is too
weak your doctor may increase the dose to 20 mg. Tadalafil tablets are for oral use.
You may take a Tadalafil tablet at least 30 minutes before sexual activity.
Tadalafil may still be effective up to 36 hours after taking the tablet.
Once a day dosing of Tadalafil may be useful to men who anticipate having sexual activity two or more
times per week.
When taken once a day Tadalafil 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 Tadalafil 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 Tadalafil, avoid excessive drinking (blood alcohol level of 0.08 %
or greater), since this may increase the risk of dizziness when standing up.
Benign prostatic hyperplasia
The dose is one 5 mg tablet taken once a day at approximately the same time of the day.
If you have benign prostatic hyperplasia and erectile dysfunction, the dose remains one 5 mg tablet taken
once a day.
Do not take Tadalafil more than once a day.

If you take more Tadalafil than you should
Contact your doctor. You may experience side effects described in section 4.
If you forget to take Tadalafil
Take your dose as soon as you remember but do not take a double dose to make up for a forgotten tablet.
You should NOT take Tadalafil more than once a day.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
