Can a woman have irregular periods with taking just one prednisone pill?

Prednisone is a corticosteroid medication used to treat a wide range of conditions. It is often prescribed to reduce inflammation and to suppress the immune system. While prednisone can cause irregular periods, this is not a common side effect. Prednisone is typically prescribed in higher doses for a longer duration of time to cause this side effect. Additionally, people who are already at risk of irregular periods, such as those with polycystic ovary syndrome (PCOS), may be more likely to experience this side effect. If you are concerned about the potential side effects of prednisone, it is important to talk to your doctor.
