What is the antidote for heparin?

The antidote for heparin is protamine sulfate. It is a medication that works by neutralizing the anti-clotting effects of heparin. Protamine sulfate can be administered intravenously (IV) and should only be given under the supervision of a healthcare provider. The dosage of protamine sulfate is based on the amount of heparin given and the patient's weight. It is important to note that protamine sulfate can cause allergic reactions in some people, so it should only be used when necessary, and patients should be closely monitored for any adverse effects.
