Is Prednisone medicine still good after 3 years?

Prednisone, like many medications, typically has an expiration date that is determined by stability testing. While some medications may remain effective beyond their expiration date, it's generally not recommended to use them after that time due to potential changes in potency or safety. If you have prednisone that is three years old, it's best to consult a healthcare professional or pharmacist for advice.
