Protamine sulfate

Protamine sulfate is a medication used to reverse the effects of certain blood thinners, specifically heparin, which helps prevent blood clots. When patients undergo surgery or have bleeding issues caused by heparin, protamine sulfate binds to the heparin and neutralizes its blood-thinning effect, helping to stop bleeding. It is administered intravenously under medical supervision to ensure safety and effectiveness. While generally safe, it can cause allergic reactions in some individuals, so healthcare providers monitor patients closely during use.
