No drug interaction studies have been conducted with lecanemab.
Elimination of lecanemab is likely to occur through normal degradation pathways for immunoglobulins and the clearance should not be affected by small molecule concomitant medications. Therefore, it is not expected that lecanemab will cause or be susceptible to pharmacokinetic (PK) drug interactions with concomitantly administered agents.
The risk of intracerebral haemorrhage with lecanemab treatment may be increased in patients receiving anticoagulant therapy or thrombolytic agents (see Contraindications and Precautions).
