Which medication is commonly used as an initial treatment for ITP?

• A. Corticosteroids
• B. Antibiotics
• C. Platelet transfusion
• D. Anticoagulants

Answer: (A)

Corticosteroids are used first-line for ITP because they blunt the immune attack on platelets. They decrease autoantibody production and lessen macrophage-mediated destruction of platelets, allowing the platelet count to rise fairly quickly. In practice, prednisone or dexamethasone is given to curb the immune response, with dosing strategies chosen to balance efficacy and side effects. This approach targets the underlying immune-mediated destruction rather than merely replacing platelets. Other options aren’t used as initial therapy for different reasons: antibiotics don’t treat the autoimmunity of ITP; platelet transfusions are rarely helpful long-term because the antibodies quickly destroy transfused platelets and are reserved for major bleeding scenarios; anticoagulants would worsen bleeding in someone with low platelets. If needed later, additional therapies can be considered for cases that don’t respond to steroids, such as IVIG, anti-D in select patients, rituximab, or splenectomy.
