Warnings and precautions

Talk to your doctor or pharmacist before taking Tamoxifen if:

  • you or any member of your family have ever had strokes or blood clots.

Co-administration with the following drugs should be avoided because a reduction of the effect of tamoxifen cannot be excluded: paroxetine, fluoxetine (e.g. antidepressants), bupropion (antidepressant or aid to smoking cessation), quinidine (for example used in the treatment of cardiac arrhythmia) and cincalet/cinacalcet (for treatment of disorders of the parathyroid gland).

In delayed breast reconstruction operation (weeks to years after the primary breast operation when your own tissue is moved to shape a new breast) tamoxifen may increase the risk of the formation of blood clots in the small vessels of the tissue flap which may lead to complications.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Tamoxifen.

Having operations and tests

  • Your doctor may give you blood tests, eye tests and gynaecological tests before and while you are taking this medicine.
