What happens
Increased risk of bleeding
Interaction Deep Dive
Use caution with the coadministration of an antiplatelet agent and a low molecular weight heparin (LMWH), as this may increase the risk of bleeding. Discontinue the antiplatelet agent prior to initiating a LMWH if possible. If discontinuation is not possible, monitor patients closely for signs or symptoms of bleeding and evaluate promptly. Lab monitoring may be appropriate1.
