6.Contents of the package and additional information

Citax is indicated for the treatment of erectile dysfunction in adult men. This condition occurs when a man is unable to obtain or maintain a firm erection, adequate for a satisfactory sexual activity. Citax has demonstrated a significant improvement in the ability to obtain a lasting erection of the penis, adequate for sexual activity.

This medication contains the active ingredient tadalafil, which belongs to a group of medications called phosphodiesterase type 5 inhibitors. After sexual stimulation, tadalafil acts by helping to relax the blood vessels of the penis, allowing blood to flow into the penis. The result is an improvement in erectile function. Tadalafil will not be effective if you do not have erectile dysfunction.

It is essential to inform you that tadalafil is not effective without sexual stimulation. Therefore, you and your partner should stimulate yourselves in the same way you would without taking a medication for erectile dysfunction.

Do not take Citax

-If you are allergic to tadalafil or any of the other components of this medication (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 medications (“nitrates”) used to treat angina pectoris (“chest pain”). Tadalafil has been seen to increase the effects of these medications. If you are taking any type of nitrates or are unsure, tell your doctor.

-If you have a serious heart condition or have had a recent heart attack, within the last 90 days.

-If you have had a recent stroke, within the last 6 months.

-If you have low or uncontrolled high blood pressure.

-If you have ever had vision loss due to non-arteritic anterior ischemic optic neuropathy (NAION), a condition described as “eye infarction”.

-If you are taking riociguat. This medication 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 clots). Phosphodiesterase type 5 inhibitors, such as tadalafil, have shown to increase the hypotensive effect of this medication. If you are taking riociguat or are unsure, consult your doctor.

Warnings and precautions

Consult your doctor before starting to take this medication.

Be aware that sexual activity poses a possible risk for patients with heart problems, due to the additional strain it puts on the heart. If you have a heart problem, consult your doctor.

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

• Thalassemia (a blood disorder).
• Multiple myeloma (bone marrow cancer).
• Leukemia (blood cancer).
• Any deformity of the penis.
• A serious liver problem.
• A serious kidney problem.

Tadalafil is not known to be effective in patients who have undergone:

• Pelvic surgery.
• A surgical procedure in which the prostate has been completely or partially removed and the nerves of the prostate have been cut (radical prostatectomy without neurovascular bundle preservation).

If you experience a sudden decrease or loss of vision or your vision is distorted or blurred 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 if the event is directly related to tadalafil, if you experience a 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

This medication should not be used in children or adolescents under 18 years old.

Taking Citax with other medications

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Do not take tadalafil if you are already using nitrates.

Some medications may be affected by tadalafil or may affect the proper functioning of tadalafil. Inform your doctor or pharmacist if you are using:

• An alpha blocker (used to treat high blood pressure or urinary symptoms associated with benign prostatic hyperplasia).
• Other medications to treat high blood pressure.
• Riociguat.
• A 5-alpha reductase inhibitor (used to treat benign prostatic hyperplasia).
• Medications such as ketoconazole tablets (for the treatment of fungal infections) and protease inhibitors for the treatment of HIV/AIDS or HIV infection.
• Phenobarbital, phenytoin, and carbamazepine (anticonvulsant medications).
• Rifampicin, erythromycin, clarithromycin, or itraconazole.
• Other treatments for erectile dysfunction.

Taking Citax with food, drink, and alcohol

Information about the effect of alcohol is found in section 3. Grapefruit juice may affect the proper functioning of tadalafil and should be taken with caution. Consult your doctor for more information.

Fertility

In dogs treated, a decrease in sperm production by the testicles was observed. A decrease in sperm count has been observed in some men. It is unlikely that these effects will cause infertility.

Driving and operating machinery

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

Citax contains lactose

This medication contains lactose. If your doctor has told you that you have a certain sugar intolerance, consult with them before taking this medication.

Follow exactly the administration instructions for this medication as indicated by your doctor. If in doubt, consult your doctor or pharmacist again.

Tadalafil tablets are for oral administration only in men. Swallow the tablet whole with a little water. Tablets can be taken with or without food.

Recommended initial doseis one 10 mg tablet before sexual activity. However, you have been given a dose of one 20 mg tablet because your doctor has decided that the recommended dose of 10 mg is too weak.

You can initiate sexual activity at least 30 minutes after taking tadalafil.

Tadalafil may still be effective up to 36 hours after taking the tablet.

You should not take tadalafil more than once a day. Tadalafil 10 and 20 mg will be used before expected sexual activity and are not recommended for continuous daily use.

It is essential to inform you that tadalafil is not effective without sexual stimulation. Therefore, you and your partner should stimulate yourselves in the same way as you would without taking a medication for erectile dysfunction.

Consuming alcohol may affect your ability to achieve an erection and 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 when standing up.

If you take more Citax than you should
