Once immune thrombocytopenic purpura (ITP) is diagnosed and other causes of thrombocytopenia have been excluded, treatment decisions depend on the patient’s platelet count, symptoms, and comorbidities. If a patient has a platelet count above 20,000 to 30,000 without active bleeding, treatment may not be necessary—close monitoring might be sufficient. However, if there is any evidence of bleeding (e.g., nosebleeds, hemorrhoid-related bleeding, or petechiae), treatment becomes necessary even at these higher platelet levels. Comorbid conditions, such as heart disease requiring antiplatelet therapy, can also influence the decision to initiate treatment sooner to avoid bleeding risks.

For patients with very low platelet counts—especially in the single digits—and active bleeding, rapid inpatient intervention is required. These cases are considered urgent due to the risk of hemorrhagic complications. First-line treatment options in such scenarios include high-dose steroids or intravenous immunoglobulin (IVIG) to quickly raise platelet levels and stabilize the patient. In more stable outpatient cases, oral steroids remain the most common approach. Dexamethasone is preferred for its quick action and short treatment duration (typically four days), while prednisone is used for longer courses but comes with a greater risk of side effects like fluid retention, hyperglycemia, or immunosuppression—especially concerning for patients with diabetes or cardiovascular conditions.

Other treatment considerations include choosing between short-term therapies that offer the possibility of treatment-free remission and long-term options requiring ongoing management. Some patients may benefit from therapies like rituximab, which is administered over a short course, while others may need regular subcutaneous injections requiring frequent clinic visits. Ultimately, treatment plans are individualized based on factors like the patient's overall health, convenience, access to care, and goals of therapy, aiming to balance efficacy with minimizing treatment burden and potential adverse effects.
