Generally, neutrophils begin to rebound back up about 1 to 2 weeks after chemotherapy in most patients, and may extend to about 3 weeks in patients with severe symptoms, but the specific situation varies from person to person.
In general, most chemotherapeutic drugs such as paclitaxel injection cause bone marrow suppression, which is more lethal to white blood cells, and therefore prone to lower neutrophils. After treatment, most patients will have a better effect of neutrophil rise, and can return to normal level in about 1~2 weeks.
However, some patients will have more obvious bone marrow suppression and lower white blood cells after chemotherapy, and the effect of white blood cells rising after treatment is not ideal, and it may be extended to about 3 weeks before the neutrophils start to rise gradually, and the specific time of rebound should also be taken into account in the patient’s personal situation.
If the neutrophil level does not return to normal after chemotherapy for more than 3 weeks, it is recommended to consult a doctor in time, under the guidance of the doctor, complete the relevant examinations, identify the cause of the disease, and target treatment. All the drugs mentioned above should be used in accordance with medical advice.
