Medications to treat underlying infections
If your white blood cell count is low, it is likely caused by an infection ravaging your immune system. Doctors trying to boost your white blood cell count and immune system often start by trying to get rid of the infection. The treatments they will prescribe depend on several factors.
The medications they give you will help fight your infection. These drugs will boost your immune system’s defense and give it time to produce and replenish lost white blood cells. If doctors suspect your leukocyte count is likely to fall, they may prescribe prophylactic antibiotics [1] to reduce the risk of infection and keep your white blood cell count up.
Stopping certain treatments
Some medications can cause your white blood cells to reduce in number. Doctors may recommend that you temporarily stop [2] these treatments to give your body time to heal and replenish your white blood cells. The duration of this recovery varies from person to person. Treatments that can cause your white cells to fall include chemotherapy and radiation.
