Does Lunesta increase or decrease in potency or change chemically when expired?

Please destroy the med or take them across to the pharmacist so that they could get rid of them, it is not recommended to use expired meds, they are no longer effective, hope this helps?

If stored in a cool dry place away from heat and moisture then its shelf life is at least a maximum of 5 years. A minimum of 2 if not stored properly.

Lunesta does infact lose potency once it begins to expire. However it will not harm you in anyway. It just may not work as well as it had in the past!
