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

Tamoxifeno Vir belongs to a group of medications known as anti-estrogens.

Estrogen is present in your body and is a natural substance known as a “sex hormone”. Tamoxifeno acts by blocking the effects of estrogen.

Tamoxifeno Vir is indicated for certain breast pathologies.

2. What you need to know before taking Tamoxifen Vir

Do not take Tamoxifeno Vir

?If you are allergic to tamoxifen or any of the other components of this medication (listed in section 6).

  • If you are pregnant (see “Pregnancy, breastfeeding and fertility”).

Warnings and precautions

Consult your doctor or pharmacist before taking tamoxifen.

  • The concomitant administration with the following medications should be avoided, as the effects of tamoxifen cannot be ruled out: paroxetine, fluoxetine (e.g. antidepressants), bupropion (antidepressant or used to quit smoking), quinidine (used in the treatment of cardiac arrhythmia) and cinacalcet/cinaclet (for the treatment of parathyroid gland disorders).
  • If you are using a contraceptive method. Consult your doctor about the contraceptive methods you should use, as some may be affected by this medication.
  • It is essential to inform your doctor immediately if you experience any unusual vaginal bleeding or other gynecological symptoms (such as pelvic pain or pressure) during treatment with tamoxifen or at any time thereafter. This is because certain changes may occur in the uterus (endometrium), some of which may be severe.
  • Before starting treatment with this medication, it is essential to inform your doctor if you or any family member has a history of blood clots or any known hereditary condition that increases the risk of blood clot formation.
  • Inform hospital staff that you are taking tamoxifen if you are admitted to a hospital.
  • In a delayed breast reconstruction surgery (weeks or years after the primary breast surgery, when your own tissue is moved to shape a new breast), tamoxifen may increase the risk of blood clot formation in small blood vessels of the tissue graft, which may lead to complications.
  • This medication contains tamoxifen, which may produce a positive result in doping control tests.
  • Severe skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, have been reported in association with tamoxifen treatment. If you experience any symptoms related to these severe skin reactions described in section 4, stop using Tamoxifeno Vir and seek medical attention immediately.
  • If you have a history of hereditary angioedema, as Tamoxifeno Vir may provoke or worsen angioedema symptoms. If you experience symptoms such as facial swelling, lips, tongue, and/or throat with difficulty swallowing or breathing, contact a doctor immediately.

Children and adolescents

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

Use of Tamoxifeno Vir with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

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

  • Warfarin (an oral anticoagulant to prevent blood clots)
  • Rifampicin (for tuberculosis).
  • Aromatase inhibitors such as anastrozole, letrozole, or exemestane (used to treat breast cancer).
  • Paroxetine, fluoxetine (antidepressants).
  • Bupropion (antidepressant or used to quit smoking).
  • Quinidine (used in the treatment of cardiac arrhythmia).
  • Cinacalcet (for the treatment of parathyroid gland disorders)

Pregnancy, breastfeeding and fertility

You should not be pregnant during treatment with tamoxifen or for two months after stopping treatment.

Do not take tamoxifen if you are breastfeeding, unless your doctor has evaluated the risks and benefits involved. It is not known if tamoxifen passes into breast milk.

Driving and operating machinery

The influence of tamoxifen on the ability to drive and operate machinery is small.

However, fatigue has been reported with tamoxifen use, so you should exercise caution when driving or operating machinery while these symptoms persist.
