There is no direct correlation between diarrhea and the ascorbic injection. Recombinant human granulocyte stimulating factor (commonly known as ascorbic acid injection) can trigger bone soreness, low-grade fever and other uncomfortable symptoms. During the period of bone marrow suppression during the use of the ascending injection, the white blood cells are low, diarrhea is recommended to check the blood routine, stool routine and other laboratory tests under the guidance of the doctor, to clarify whether it is infectious diarrhea. If it is infectious diarrhea, antibiotics (such as cephalosporin) can be taken under the guidance of the doctor for treatment. In addition, during chemotherapy, it is easy to cause diarrhea, abdominal pain, anorexia and other symptoms. It is recommended to go to the regular hospital for examination to identify the specific causes of diarrhea and to carry out treatment.
