Objectively, the effect of therapy is usually observed after 4-10 weeks of treatment, but in the case of metastases in the bones, the effect can be observed only after several months of treatment.
The duration of treatment with tamoxifen is determined by the severity and course of the disease. Usually treatment is lengthy. “
In the treatment of elderly patients or patients with impaired liver or kidney function, dose adjustment is not required.
Side effect
Disorders from the blood system: rarely – thrombocytopenia (the number of platelets decreases to 80,000 – 90,000 / mm3), leukopenia; Very rarely – neutropenia, pancytopenia. Impaired vision: visual acuity, retinopathy, keratopathy, cataract. These effects probably depend on the doses and duration of therapy and can be partially reversible after cessation of tamoxifen treatment.

Benign and malignant neoplasms with terapyatemoxifen are associated with an increased risk of proliferative changes in the endometrium, in particular, endometrial hyperplasia, polyps, endometriosis and, in rare cases, endometrial cancer. The likelihood of developing endometrial cancer increases with increasing duration of tamoxifen therapy and approximately 2 to 3 times the likelihood of endometrial cancer in women who have not received the drug. However, the clinical benefit of using tamoxifen in the treatment of breast cancer in women exceeds the possible risk of development of neoplastic endometrial structures.
Vascular disorders: often enough – thrombosis; Very rarely – pulmonary embolism. With the parallel use of tamoxifen and cytotoxic drugs, the risk of thromboembolic complications increases.
Disorders from the immune system: rarely – hypersensitivity reactions, including skin rash, angioedema, polymorphic erythema, Stevens-Johnson syndrome, bullous pemphigoid.
