1. What Tadalafilo Alter is and what it is used for

Tadalafilo Alter contains the active substance tadalafil, which belongs to a group of medicines called phosphodiesterase type 5 inhibitors.

Tadalafil 5 mg is used to treat adult men with:

• Erectile dysfunction. This occurs when a man cannot achieve or maintain a firm erection suitable for satisfactory sexual activity. Tadalafil has been shown to significantly improve the ability to achieve a durable penile erection suitable for sexual activity.

After sexual stimulation, tadalafil works by helping to relax the blood vessels in the penis, allowing blood to flow into the penis. The result is improved erectile function. Tadalafil will not help if you do not have erectile dysfunction. It is important to note that tadalafil is not effective without sexual stimulation. Therefore, you and your partner must stimulate each other in the same way 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 occurs when the prostate gland enlarges over time. Symptoms include difficulty starting to urinate, a sensation that the bladder has not emptied completely, and a need to urinate more frequently, even at night. Tadalafil improves blood flow and relaxes the muscles of the prostate and bladder, which may reduce the symptoms of benign prostatic hyperplasia. Tadalafil has been shown to improve these urinary symptoms within as little as 1–2 weeks after starting treatment.

2. What you need to know before taking Tadalafil Alter

Do not take Tadalafil Alter

• if you are allergic to tadalafil or to any of the other ingredients of this medicine (listed in section 6).
• if you are taking any type of organic nitrates or nitric oxide donors such as amyl nitrite. This is a group of medicines ("nitrates") used to treat angina pectoris ("chest pain"). Tadalafil has been shown to increase the effects of these medicines. If you are taking any type of nitrate or are unsure, tell your doctor.
• if you have a severe heart disease or have recently had a heart attack (within the last 90 days).
• if you have recently had a stroke (within the last 6 months).
• if you have low blood pressure or uncontrolled high blood pressure.
• if you have ever experienced vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION), a condition described as "stroke of the eye".
• if you are taking riociguat. This medicine 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 caused by blood clots). PDE5 inhibitors such as tadalafil have been shown to increase the hypotensive effect of this medicine. If you are taking riociguat or are unsure, consult your doctor.

Warnings and precautions

Talk to your doctor before starting to take Tadalafil Alter.

Be aware that sexual activity carries a potential risk for patients with heart problems, due to the additional strain placed on the heart. If you have a heart condition, consult your doctor.

Since benign prostatic hyperplasia and prostate cancer can have similar symptoms, your doctor will perform a prostate cancer evaluation before starting treatment with tadalafil for benign prostatic hyperplasia. Tadalafil does not treat prostate cancer.

Before taking the tablets, inform your doctor if you have:

• sickle cell anemia (an abnormality of red blood cells).
• multiple myeloma (a cancer of the bone marrow).
• leukemia (a cancer of blood cells).
• any deformity of the penis.
• a severe liver problem.
• a severe kidney problem.

It is not known whether tadalafil is effective in patients who have undergone:

• pelvic surgery.
• a surgical procedure in which the prostate has been partially or completely removed and the nerves to the prostate have been severed (radical prostatectomy without neurovascular bundle preservation).

If you experience a sudden decrease or loss of vision, or if your vision becomes distorted or dimmed while taking tadalafil, stop taking tadalafil and contact your doctor immediately.

Sudden decrease or loss of hearing has been observed in some patients taking tadalafil. Although it is not known whether this is directly related to tadalafil, if you experience sudden decrease or loss of hearing, stop taking tadalafil and contact your doctor immediately.

Tadalafil is not intended for use in women.

Children and adolescents

Tadalafil must not be used in children or adolescents under 18 years of age.

Taking Tadalafil Alter with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Do not take tadalafil if you are already using nitrates.

Some medicines may be affected by tadalafil or may affect how well tadalafil works. Inform your doctor or pharmacist if you are taking:

• an alpha-blocker (used to treat high blood pressure or urinary symptoms associated with benign prostatic hyperplasia).
• other medicines for treating high blood pressure.
• riociguat.
• a 5-alpha reductase inhibitor (used to treat benign prostatic hyperplasia).
• medicines such as ketoconazole tablets (for treatment of 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.

Taking Tadalafil Alter with food and alcohol

Information about the effect of alcohol is provided in section 3. Grapefruit juice may affect how well tadalafil works and should be consumed with caution. Consult your doctor for further information.

Fertility

In treated dogs, a decrease in sperm production by the testes was observed. Some men have shown reduced sperm count. It is unlikely that these effects would lead to infertility.

Driving and using machines

Some men who took tadalafil during clinical trials experienced dizziness. Carefully assess how you react when taking the tablets before driving or operating machinery.

Tadalafil Alter contains lactose

This medicine contains lactose. If your doctor has informed you of an intolerance to certain sugars, consult with him before taking this medicine.

Tadalafil Alter contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per tablet; hence, it is essentially "sodium-free".

Tadalafil Alter contains aspartame

This medicine contains 2.04 mg of aspartame per tablet.

Aspartame contains a source of phenylalanine, which may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body cannot properly eliminate it.

3. How to take Tadalafil Alter

Follow exactly the instructions for use of this medicine provided by your doctor. If in doubt, consult your doctor or pharmacist again.

Tadalafil orodispersible tablets are for oral use only in men. They are administered as a single dose and may be taken with or without food. The orodispersible tablet should be placed on the tongue, where it dissolves and can be swallowed without water.

Alcohol consumption may temporarily lower your blood pressure. If you have taken or are planning to take tadalafil, avoid excessive alcohol consumption (blood alcohol level of 0.08% or higher), as it may increase the risk of dizziness upon standing.

For the treatment of erectile dysfunction

The recommended dose is one 5 mg tablet once daily, taken at approximately the same time each day. Your doctor may adjust the dose to 2.5 mg depending on your response to tadalafil. This will be achieved by taking one 2.5 mg tablet.

Do not take tadalafil more than once a day.

Daily administration of tadalafil allows you to achieve an erection at any time during the 24-hour day, provided sexual stimulation is present. Daily tadalafil may be beneficial for men who anticipate having sexual activity two or more times per week.

It is important to note that tadalafil is not effective in the absence of sexual stimulation. Therefore, you and your partner should engage in the same kind of stimulation as you would if you were not taking a medicine for erectile dysfunction.

Alcohol consumption may affect your ability to achieve an erection.

For the treatment of benign prostatic hyperplasia

The dose is one 5 mg tablet once daily, taken at approximately the same time each day.

If you have benign prostatic hyperplasia and erectile dysfunction, the dose remains one 5 mg tablet once daily.

Do not take tadalafil more than once a day.

If you take more Tadalafil Alter than you should

Consult your doctor. You may experience adverse effects described in section 4.

In case of overdose or accidental ingestion, you may also call the Toxicology Information Service at telephone number 91 562 04 20, indicating the medication and the amount taken. It is recommended to bring the medicine packaging and leaflet to the healthcare professional.

If you forget to take Tadalafil Alter

Take your dose as soon as you remember, but do not take a double dose to make up for the missed dose. Do not take tadalafil more than once a day.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
