Most antineoplastic drugs, sulfonamides and streptomycins in antibiotics, isoniazid and rifampicin in antituberculosis drugs, phenytoin sodium in antiepileptic drugs, analgesics and antipyretics, methyl dopa in antihypertensive drugs, thiazide in diuretics, acetylsalicylic acid in antiplatelet drugs, heparin in anticoagulants, and estrogen Drugs and so on. Patients may develop thrombocytopenia within hours to days after taking the above drugs. There are also anti-rheumatic analgesics such as Baotaisong and indomethacin, which are currently more common drugs leading to drug-induced thrombocytopenia. In addition, there is a powerful narcotic analgesic drug, morphine, which occasionally causes immune thrombocytopenia. Morphine-dependent anti-platelet antibodies can be found in the serum of patients. Morphine, as a powerful analgesic, is often used in severe pain and in patients with advanced tumors. It is necessary to observe the changes of platelets in order to find out the problems in time and treat them properly.
I hope the above information will be useful to you.
