6 Contents of the pack and other information

• 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.
• 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”.
• are taking riociguat. This drug is used to treat pulmonary arterial hypertension (i.e. high blood pressure in the lungs) and chronic thromboembolic pulmonary hypertension (i.e. high blood pressure in the lungs secondary to blood clots). PDE5 inhibitors, such as Tadalafil, have been shown to increase the hypotensive effects of this medicine. If you are taking riociguat or are unsure, tell your doctor.

Talk to your doctor or pharmacist before taking Tadalafil.

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.

• sickle cell anaemia (an abnormality of red blood cells).
• multiple myeloma (cancer of the bone marrow).
• leukaemia (cancer of the blood cells).

If you experience sudden decrease or loss of vision, stop taking Tadalafil and contact your doctor immediately.

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 nitrates.

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).

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.

A reduction in sperm was seen in some men and reduced sperm development was seen during testing, in dogs. These effects are unlikely to lead to a lack of fertility.

Some men taking Tadalafil in clinical studies have reported dizziness. Check carefully how you react to the tablets before driving or using machines. If you experience side effects which may affect your ability to drive or operate machinery safely, then do not do either of these activities until the effects have completely disappeared.

If you have been told by your doctor you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

Tadalafil 10mg and 20mg is intended for use prior to anticipated sexual activity and is not recommended for continuous daily use.

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, which equates to approximately 4 units of alcohol for a man of average weight), since this may increase the risk of dizziness when standing up.

Contact your doctor. You may experience side effects described in section 4.

• chest pain - do not use nitrates but seek immediate medical assistance (frequency uncommon).
