Key Points:

• Immune thrombocytopenic purpura (ITP) causes low platelets, by definition less than 100,000 microL, in the setting of a normal bone marrow and no other cause of thrombocytopenia.
• ITP can be acute or chronic meaning lasting longer than 6 months.
• Acute ITP can be self limiting and not require treatment but treatment can include steroids, IVIG, thrombopoietin receptor agonists (TPO-RA like eltrombopag), or Rhogam.
• Chronic ITP can include rituximab, eltrombopag, and/or splenectomy
