Summary

Imatinib can cause thrombocytopenia and occasionally hemorrhage, so adding a therapeutic-dose anticoagulant may raise the bleeding risk. Low-molecular-weight heparin is preferred over warfarin in patients on imatinib because of imatinib's effect on warfarin metabolism.

What this interaction means in plain words

Dalteparin and Imatinib can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Dalteparin belongs to Cardiovascular; Imatinib belongs to Oncology.

Evidence level: Moderate

Why it happens

Additive bleeding risk from imatinib-related thrombocytopenia and platelet dysfunction together with anticoagulation by dalteparin.

What to do

Monitor platelet counts and watch for bleeding during combined use. Reduce or hold dalteparin if significant thrombocytopenia occurs.
