DITP

Q: How much time does it take for platelets to recover after the discontinuation of a drug in Drug-Induced Thrombocytopenia (DITP)?



Answer: one week

Many times it is hard to know the reason behind thrombocytopenia in ICU. One of the major causes of thrombocytopenia in ICU is Drug-Induced. It is extremely important to confirm the recovery of platelet count after the discontinuation of the drug to confirm the diagnosis of DITP. The platelet count usually starts to increase within a day or two days after the discontinuation of the drug. Full recovery usually occurs within a week. 


 Few exceptions are patients who are in severe liver or renal insufficiency. Also, some drugs take more than usual expected time in recovery particularly alemtuzumab, eptifibatide, and gold salts.
