Summary

Tranexamic acid is antifibrinolytic and oral tretinoin used for acute promyelocytic leukaemia is associated with thrombotic events. Together they may add to the risk of thrombosis, and some labeling advises caution. The concern is chiefly with systemic tretinoin.

What this interaction means in plain words

Tranexamic acid and Tretinoin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Tranexamic acid belongs to Cardiovascular; Tretinoin belongs to Dermatology.

Evidence level: Low

Why it happens

Additive prothrombotic effects: tranexamic acid inhibits fibrinolysis while tretinoin is associated with a procoagulant state.

What to do

Avoid the combination where possible, particularly in acute promyelocytic leukaemia with coagulopathy. If it is necessary, monitor for signs of venous or arterial thrombosis and coagulation parameters.
