A member asked:

My current birth control (lo loestrin fe) is a sample. it is not expired. is it still effective? what would make birth control less effective?

A doctor has provided 1 answer

Expiration dates: If the medication is not expired it will work and is no less effective. Expired medications deteriorate over time and may be less effective or not work at all.
