How to take, the dosage

The dosing regimen is established individually, depending on the indication, the patient’s condition, and the antitumor therapy regimen used.

Interaction

Concomitant use with anticoagulants coumarin derivatives increases the risk of increased anticoagulant effect; with cytostatics – possible increased risk of thrombosis.

In concomitant use with allopurinol hepatotoxic effect is possible; with aminoglutethimide – decrease of plasma concentration of tamoxifen, probably due to its increased metabolism.

In patients receiving tamoxifen, atracurium-induced neuromuscular blockade may be prolonged.

The concomitant use of bromocriptine may increase the dopaminergic effect of bromocriptine. In patients receiving tamoxifen, when using warfarin, there is a risk of developing a threatening clinical situation: prolongation of prothrombin time, hematuria, hematoma are possible.

Concomitant use with mitomycin increases the risk of hemolytic-uremic syndrome.

The concentration of tamoxifen in plasma may decrease, which appears to be due to induction of CYP3A4 isoenzyme by rifampicin.

Estrogens may decrease the therapeutic effect of tamoxifen.
