1. What is Tamoxifeno Tillomed and what is it used for

Tamoxifeno belongs to the group of medications called "anti-estrogens".

Estrogens are natural substances found in the body, also known as "sex hormones". Tamoxifeno works by blocking the effects of estrogens in the body.

Tamoxifeno is indicated:

• For adjuvant therapy after initial treatment of breast cancer and treatment of secondary tumors (metastases) of breast cancer.
• In adult men for the prevention of breast enlargement (gynecomastia) and breast pain (mastalgia) caused by medications called anti-androgens used in the treatment of prostate cancer (prostatic carcinoma).

Consult your doctor if you do not feel better or if you feel worse.

2. What you need to know before taking Tamoxifeno Tillomed

Do not taketamoxifeno

• if you are allergic to tamoxifen citrate or any of the other components of this medication (listed in section 6).
• If you are pregnant or breastfeeding.

Warnings and precautions

Consult your doctor or pharmacist before starting to take tamoxifeno.

Special care is required:

• if you have a significantly low level of platelets (thrombocytopenia) or white blood cells (leukopenia) or elevated calcium levels in the blood (hypercalcemia). In these circumstances, your doctor will ask you to have periodic blood tests.
• If you have ever had a lack of blood flow to the brain (stroke), similar events to stroke, conditions resulting from the formation and release of blood clots (thromboembolism) or uterine cancer, as these conditions may occur again during treatment with tamoxifeno
• If you have a particular type of breast cancer (ductal carcinoma in situ), specifically if you are receiving simultaneous treatment to thin the blood or if you have had a blood clot in a blood vessel (deep vein thrombosis or pulmonary embolism) in the past, the decision to start therapy with tamoxifeno should be discussed with your doctor to evaluate the potential risks and benefits.
• If you have high levels of certain lipids in the blood (triglycerides) during treatment with tamoxifeno. This medication may cause an alteration in the metabolism of lipids in the blood (hypertriglyceridemia).
• If you have postmenopausal bleeding or irregular bleeding before menopause. The cause of such bleeding should be clarified immediately with a gynecologist. Additionally, you should discuss the need for an annual gynecological examination with your doctor to determine changes in the endometrium or other investigations.
• If you experience visual disturbances during treatment with tamoxifeno. In this case, you should be examined urgently by an ophthalmologist, as some changes, when recognized in the early stages, are reversible after discontinuation of treatment with tamoxifeno. In general, an ophthalmological examination should be performed before starting therapy with tamoxifeno.
• In delayed breast reconstruction surgery (weeks or years after primary breast surgery, when your own tissue is moved to shape a new breast), tamoxifeno may increase the risk of blood clot formation in the small blood vessels of the tissue graft, which can lead to complications.

In case of hospitalization, inform the healthcare staff that you are taking tamoxifeno:

Surgery and immobility

If you are going to undergo surgery or will be unable to move for a long time, you should take the following precautions:

• If you are taking tamoxifeno for breast cancer or for the prevention of gynecomastia: your doctor should decide whether it is best for you to continue taking tamoxifeno. You may need to wear special stockings called compression stockings while hospitalized or be given an anticoagulant. These reduce the risk of a blood clot.

During administration of tamoxifeno, your doctor will need to periodically monitor your blood profile, calcium levels in the blood, and liver function. You should also have your triglyceride levels in the blood checked.

Use in athletes:

This medication contains tamoxifeno, which may produce a positive result in doping tests.

Children and adolescents

Tamoxifeno should not be administered to children/adolescents, as its safety and efficacy in this age group have not been established.

Other medications and Tamoxifeno

Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication, including those obtained without a prescription.

In particular, you should inform your doctor if you are taking any of the following medications:

• Paroxetine, fluoxetine (antidepressants).
• Bupropion (antidepressant or used to quit smoking).
• Quinidine (used to treat cardiac arrhythmia).
• Cinacalcet (for the treatment of parathyroid disorders)
• Cytotoxic medications (used to treat cancer) as they may increase the risk of blood clot formation.

Your doctor should perform frequent blood tests if you are taking medications to thin the blood, called anticoagulants of the dicumarin type (e.g., warfarin). In fact, tamoxifeno may significantly enhance the effect of these medications.

The use of tamoxifeno in combination with another medication for the treatment of breast cancer (aromatase inhibitor) as adjuvant therapy has not shown greater efficacy compared to tamoxifeno alone.

In some studies, a decrease in the efficacy of tamoxifeno has been reported when administered concomitantly with certain antidepressants (e.g., paroxetine).

The effect of the following medications or groups of preparations may be influenced by concomitant therapy with tamoxifeno.

Enhance the effect up to a greater risk of side effects:

• Anticoagulant medications. Do not combine tamoxifeno with these medications unless your doctor has given you specific instructions. Due to the increased tendency to bleed, laboratory appointments should be followed with great care.
• Concomitant chemotherapy. There is some evidence that tamoxifeno may increase the formation of blood clots (thromboembolic events, including deep vein thrombosis and pulmonary embolism). This incidence increases with concomitant chemotherapy.

Decrease the effect of:

• Hormonal preparations, specifically estrogen compounds (such as "the pill"): a mutual decrease in effects is possible. Therefore, these medications should not be taken during treatment with tamoxifeno.

Pregnancy andbreastfeeding

Pregnancy

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Since there is insufficient experience with the use of tamoxifeno during pregnancy, you should not take tamoxifeno during pregnancy. Pregnancy should be ruled out before starting treatment. Women of childbearing age should use a non-hormonal effective contraceptive method (such as barrier methods or non-hormonal methods) until two months after discontinuing treatment, as there may be risks to the child. (See also "Other medications and tamoxifeno").

In premenopausal women, tamoxifeno may suppress menstrual bleeding (see section 4 "Possible side effects"). Therefore, your doctor should perform tests to exclude the possibility of pregnancy before starting treatment.

Breastfeeding

Tamoxifeno inhibits lactation in humans at high doses, and milk production does not resume even after treatment is discontinued. It is unknown whether tamoxifeno is excreted in human breast milk. Therefore, you should not take tamoxifeno during breastfeeding. If treatment is justified, your doctor will evaluate the risk-benefit before administering this medication to you.

Driving and using machines

It is unlikely that this medication will affect your ability to drive vehicles or operate hazardous machinery. However, fatigue, drowsiness, and visual disturbances have been reported with the use of tamoxifeno, and you should exercise caution when driving or using machines while such symptoms persist.

Tamoxifeno Tillomed contains lactose

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

Tamoxifeno Tillomed contains sodium

This medication contains less than 23 mg of sodium (1 mmol) per tablet; this is essentially "sodium-free".

3. How to take Tamoxifeno Tillomed

Follow the instructions for administration of this medication indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

Oral use only. Swallow the tablet whole, without chewing, with sufficient liquid (such as a glass of water), preferably with a meal.

The recommended dose for the treatment of breast cancer is 20 to 40 mg per day. It is usually taken once or twice a day. In general, a dose of 20 mg is sufficiently effective.

The recommended dose for the prevention of breast enlargement and pain caused by anti-androgen medications used in the treatment of advanced prostate cancer is 20 mg once a day.

Treatment with tamoxifeno is generally long-term. Your doctor will indicate the duration of treatment. In adjuvant treatment of early breast cancer, the duration of treatment is usually 5 years.

If you take more Tamoxifeno than you should

If you ingest a dose higher than normal, contact your doctor or the nearest hospital.

In case of overdose or accidental ingestion, consult your doctor or pharmacist or call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount ingested.

If you forget to take Tamoxifeno

If you forget a dose, take it as soon as you remember.

Do not take a double dose to make up for forgotten doses.

If you interrupt treatment with Tamoxifeno

Do not interrupt administration of tamoxifeno without consulting your doctor first, as the success of your treatment may be at risk.

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