A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
How do you diagnose HIT?
Diagnosis of HIT is based on clinical assessment and laboratory results. Primary laboratory tests for HIT include immunologic assays, such as an enzyme-linked immunosorbent assay (ELISA), and functional, platelet-activation assays, such as the serotonin release assay (SRA).
What is the most serious clinical consequence of heparin-induced thrombocytopenia?
Thrombocytopenia is severe and frequently results in bleeding. Thrombosis in HIT is associated with a mortality of approximately 20–30% Obstetric patients are particularly at risk of developing thrombotic complications. Females are more likely to suffer thrombotic stroke as an outcome of their HIT.
What does heparin do to skin?
Heparin can also give rise to other cutaneous reactions, including: Purpura and paradoxical formation of clots in blood vessels in heparin-induced thrombocytopenia (HIT) Injection-site erythema, and eczematous, painful or itchy plaques. Generalised hypersensitivity reactions such as acute urticaria.
What type of allergy should you be concerned about when giving a client heparin?

Can you have an allergic reaction to heparin?
Allergy warning Heparin can cause a severe allergic reaction. Symptoms can include: skin tissue death at the injection site. chills.
What is the antidote to heparin?
Expert opinion: Despite of the low therapeutic index, protamine is the only registered antidote of heparins. The toxicology of protamine depends on a complex interaction of the high molecular weight, a cationic peptide with the surfaces of the vasculature and blood cells.
How do you reverse heparin-induced thrombocytopenia?
High-dose intravenous immunoglobulin (IVIG) has been used as an adjunct to anticoagulation in patients with HIT. At a usual dose of 1 g/kg for 2 days, IVIG is typically effective in interrupting platelet activation by HIT antibodies and results in a rapid increase in the platelet count.
How does heparin cause skin necrosis?
What is heparin-induced skin necrosis? Heparin-induced skin necrosis is a rare complication of heparin injections either at the injection site or distant sites, in which there is the death of skin cells (necrosis) due to the inadequate blood supply.
Why does heparin induced thrombocytopenia cause thrombosis?
When thrombosis is identified the condition is called heparin-induced thrombocytopenia and thrombosis ( HITT ). HIT is caused by the formation of abnormal antibodies that activate platelets. If someone receiving heparin develops new or worsening thrombosis, or if the platelet count falls, HIT can be confirmed with specific blood tests.
Is heparin contraindicated in thrombocytopenia?
The use of heparin sodium is contraindicated in patients: With history of heparin-induced thrombocytopenia (HIT) (With or Without Thrombosis) [see Warnings and Precautions (5.3) ] With a known hypersensitivity to heparin or pork products (e.g., anaphylactoid reactions) [see Adverse Reactions (6.1) ]
Why is heparin contraindicated in active tuberculosis?
Fatal Medication Errors.
Is rhabdomyolysis a side effect of heparin?
Thrombocytopenia, heparin-induced thrombocytopenia (HIT) and heparin-induced thrombocytopenia and thrombosis (HITT) are serious side effects of heparin.
