WASHINGTON (AP) - A drug used to prevent blood loss during heart bypass surgery has been linked to higher risks of serious side effects, including kidney problems, heart attacks and strokes, health officials warned doctors and patients Wednesday.
The Food and Drug Administration said it was evaluating the safety of Trasylol, formally known as aprotinin, in light of two studies published in January that link its use to the problems.
The drug's maker, Germany-based Bayer AG, said the drug is safe and effective when used correctly in artery bypass graft surgery patients.
