Thyroid + Oral Anticoagulants Interaction

Majorinteraction on record

Description

Thyroid hormones increase catabolism of vitamin K-dependent clotting factors, impairing compensatory increases in clotting factor synthesis. Patients stabilized on oral anticoagulants starting thyroid replacement require close monitoring and likely need anticoagulant dose reduction.

Mechanism

Increased catabolism of vitamin K-dependent clotting factors
