This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

My niece got a fever for the past eight days. Also, low white blood cells (WBC) count. The doctors tried all the tests, antibiotics and medicines, but still, the fever is not controlled. She got fits 15 days back and the doctors prescribed Eptoin tablets. My question is whether Eptoin reduce the white blood cell counts?

Hello,

Welcome to icliniq.com. I understand your concern and would explain that Eptoin (Phenytoin) is a drug used to treat or prevent seizures. It does not usually affect WBC, but very rarely (like all the drugs) it can cause suppression of the blood cell formation in the bone marrow. The low WBC count can be related to different possible causes like viral disease, an autoimmune disorder, drug adverse effects, etc. A myelogram may be needed to exclude a possible hematological disorder. In the meantime, I recommend taking Eptoin, as it is well known that high fever can lead to seizures. I would also recommend taking steroids, because they can increase white blood cells (WBC) and also help fight the fever.
