Thanks for contacting HCM with you health care questions. I am sorry to hear that your son has had recently typhoid and now malaria. His doctor has prescribed medication for malaria usually an antibiotic related to chloroquine and also ofloxacin. I am not sure why your doctor would have given the ofloxacin since it is not used for the treatment of malaria. Perhaps the doctor was treating some other ongoing infection or continued treatment for the typhoid. I would recommend discussing this with his doctor to get better information on why he is taking ofloxacin. Hope I answered your question. Please contact us again with your medical concerns
