If you have surgery scheduled soon, you may need to set aside your over-the-counter dietary supplements for a while.
Some supplements can interact with drugs given before, during or after orthopaedic surgery, according to a review of studies in the Journal of the American Academy of Orthopaedic Surgeons.
“The main problem with using [supplements] is their interaction with anticoagulants used around the time of surgery,” according to study author David T. Rispler, MD, director of the Grand Rapids/Michigan State Orthopedic Surgery Residency. Many supplements can interfere with anticoagulants, such as warfarin, brand name Coumadin, which are used to reduce the risk of blood clots.
