If you're in your nadir period, the good news is that you just completed another round of chemotherapy and are one step closer to having this behind you. However, you may be more likely to develop an infection during your nadir because your body’s first line of defense (white blood cells) will be at its lowest point. You should carefully watch for signs and symptoms of infection during this time.
You can also take extra precautions to prevent infections, like washing your hands regularly and staying away from sick people.
To help strengthen your immune system during chemotherapy, your doctor may prescribe medicine that will help your body make more white blood cells. The medicine may shorten the duration of your nadir.
