Thymoglobulin (Anti-Thymocyte Globulin (Rabbit)) - Drug Interactions, Contraindications, Overdosage, etc



Drug Interactions

  • No drug interaction studies have been performed.
  • Because Thymoglobulin is administered to patients receiving a standard immunosuppressive regimen, this may predispose patients to overimmunosuppression. Many transplant centers decrease maintenance immunosuppression therapy during the period of antibody therapy.
  • Thymoglobulin can stimulate the production of antibodies which crossreact with rabbit immune globulins (See Pharmacokinetics and Immunogenicity ).


Thymoglobulin overdosage may result in leukopenia (including lymphopenia and neutropenia) or thrombocytopenia, which can be managed with dose reduction (See DOSAGE AND ADMINISTRATION ).


Thymoglobulin is contraindicated in patients with history of allergy or anaphylaxis to rabbit proteins or to any product excipients, or who have active acute or chronic infections which contraindicate any additional immunosuppression.
