Can prednisolone affect the immune system?

Prednisolone is a steroid. Steroid medications can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using steroid medication.

Do not receive a "live" vaccine while you are taking prednisolone. Vaccines may not work as well while you are taking a steroid.
