Heparin-Induced Thrombocytopenia (HIT) – Part 3
In Type 2 HIT the heparin should always be discontinued. The platelet count will usually start to rise after 2 to 3 days and usually returns to normal within 4 to 10 days. The antibody that is formed by the body against the heparin (that also affects the platelets) will usually disappear within 2 to 3 months of cessation of heparin therapy. Although HIT does not invariably recur during subsequent exposure to heparin, future heparin administration must be approached with much clinical caution and vigilance.
Patients should be told that they experienced a HIT reaction if it occurs and patients should always report this in any medical history.
