Frequently Asked Questions
What is HIT (Heparin-Induced Thrombocytopenia)?
HIT is a serious immune reaction to heparin where the body develops antibodies that destroy platelets, paradoxically causing massive clotting throughout the body. It requires immediate discontinuation of heparin.
How is Heparin different from Warfarin?
Heparin is given via injection and works immediately, making it ideal for acute clots. Warfarin is an oral tablet that takes several days to become fully effective and is used for long-term therapy.
