1. What Tamoxifen-EGIS is and what it is used for

Tamoxifen-EGIS belongs to a group of anti-hormonal medicines. It is a non-steroidal agent which in certain tissues exerts effects similar to estrogen (a female sex hormone), while in other tissues it blocks the effects of estrogen.
Due to its complex action, this medicine is indicated for the treatment of breast cancer.

2. Important information before using Tamoxifen-EGIS

When not to use Tamoxifen-EGIS

  • If the patient is allergic to tamoxifen or to any of the other ingredients of this medicine (listed in section 6);
  • If the patient is pregnant.

Do not take Tamoxifen-EGIS if any of the above conditions apply to the patient. If in doubt, consult a doctor or pharmacist before starting to use Tamoxifen-EGIS.

Warnings and precautions

Talk to your doctor or pharmacist before starting to use Tamoxifen-EGIS. Other health problems may affect whether this medicine can be used, so you should inform your doctor:

  • if the patient has impaired liver function,
  • if the patient has previously had blood clots and the doctor has not determined their cause,
  • if someone in the patient’s family has had unexplained blood clots,
  • if the doctor has diagnosed the patient with an inherited condition that increases the risk of blood clots,
  • if the patient has bone metastases, as calcium levels in the blood may increase at the beginning of treatment,
  • if the patient has high levels of lipids (cholesterol, triglycerides) in the blood, as lipid levels may increase during treatment,
  • if the patient has thyroid disease, as Tamoxifen-EGIS may affect thyroid function test results,
  • if the patient has haematopoietic disorders (blood disorders), as treatment with Tamoxifen-EGIS may lead to a decrease in blood cell counts,
  • if the patient has eye problems (cataracts), as vision disturbances and eye problems have been reported in a few cases during treatment with Tamoxifen-EGIS,
  • if the patient has ever had hereditary angioedema, as Tamoxifen-EGIS may cause or worsen symptoms of hereditary angioedema. If symptoms such as swelling of the face, lips, tongue and/or throat, or difficulty swallowing or breathing occur, contact a doctor immediately.

Severe skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, have occurred during treatment with Tamoxifen-EGIS. If the patient notices any of the symptoms associated with these severe skin reactions described in section 4, treatment with Tamoxifen-EGIS should be stopped immediately and medical advice should be sought without delay.

Avoid concomitant use of the following medicines, as they may reduce the effectiveness of tamoxifen: paroxetine, fluoxetine (antidepressants), bupropion (an antidepressant and smoking cessation aid), quinidine (used to treat heart rhythm disorders), and cinacalcet (used to treat parathyroid disorders).

In cases of delayed breast reconstruction (weeks or years after the initial surgery, when tissue flaps are transplanted to restore breast shape), Tamoxifen-EGIS may increase the risk of blood clots in the small vessels of the transplanted tissue flaps, which may lead to complications.

Surgical procedures

If the patient is due to undergo surgery (including planned surgical procedures), inform the doctor that the patient is taking this medicine. The doctor may advise temporarily stopping Tamoxifen-EGIS.

Children and adolescents

Tamoxifen-EGIS must not be used in children.

Tamoxifen-EGIS and other medicines

Inform your doctor or pharmacist about all medicines currently or recently taken, as well as any medicines planned for future use.

This is because Tamoxifen-EGIS may affect the action of certain medicines, and some medicines may affect Tamoxifen-EGIS.

In particular, inform the doctor if the patient is taking:

  • medicines such as warfarin, used to thin the blood. These are known as anticoagulants,
  • rifampicin, used to treat tuberculosis,
  • medicines such as anastrozole, letrozole and exemestane, known as aromatase inhibitors, used in the treatment of breast cancer,
  • paroxetine, fluoxetine (antidepressants),
  • bupropion (an antidepressant and smoking cessation aid),
  • quinidine (used to treat heart rhythm disorders),
  • cinakalcet (used to treat parathyroid disorders).

Tamoxifen-EGIS and alcohol

Alcohol consumption is not recommended during treatment with Tamoxifen-EGIS.

Pregnancy, breastfeeding and fertility

If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a child, she should consult a doctor or pharmacist before using this medicine.

Tamoxifen-EGIS must not be used if the patient is pregnant, as it may harm the unborn child. In women of childbearing potential, pregnancy must be excluded before starting treatment, and effective non-hormonal contraception must be used throughout the treatment period and for an additional 2 months after treatment ends. If a patient becomes pregnant while taking tamoxifen, she should inform her doctor as soon as possible.

It is not known whether Tamoxifen-EGIS is excreted in human breast milk, and therefore its use during breastfeeding is not recommended. If treatment is essential for the mother, breastfeeding should be discontinued.

Driving and operating machinery

Tamoxifen-EGIS has no influence on the ability to drive or operate machinery. However, since fatigue has been reported after taking tamoxifen, caution should be exercised when driving or operating machinery if such symptoms persist.

Tamoxifen-EGIS contains lactose and sodium

Each tablet contains 216.4 mg of lactose.

If the patient has been previously diagnosed with intolerance to certain sugars, the patient should consult a doctor before taking this medicine.

This medicine contains less than 1 mmol of sodium (23 mg) per tablet, i.e. the medicine is considered "sodium-free".

3. How to use Tamoxifen-EGIS

This medicine should always be taken according to the instructions given by the doctor or pharmacist. If in doubt,
consult the doctor or pharmacist.
Recommended dose:
For the treatment of breast cancer, the recommended dose is 20 mg to 40 mg per day, administered in divided doses
twice daily or as a single daily dose. Treatment is long-term and may last for several years.
Taking more Tamoxifen-EGIS than prescribed
If more Tamoxifen-EGIS is taken than prescribed, medical advice should be sought immediately.
Missing a dose of Tamoxifen-EGIS
If a dose of Tamoxifen-EGIS is missed, it should be taken as soon as the patient remembers. However, if it is almost time for the next dose, the missed dose should be skipped. Do not take a double dose to make up for a missed tablet. Continue treatment according to the doctor's previous instructions.
Stopping Tamoxifen-EGIS treatment
Do not stop taking Tamoxifen-EGIS unless instructed by the doctor, as this may lead to worsening of the disease.
