Pharmacy/Percocet and expiration timeframe

Question
dear Dr.,

I had ear surgery Thu. (5/3/07) and got a generic script for percocet 7.5-325mg.  I wanted to use my old script first (from 1/2003) generic percocet 5-325 mg.  What are the side effects/adverse reactions from a 4 year old generic perscription of percocet?  I took one so far, but want to know if I'm doing more harm than good taking the 4 yr old script.

Thank you in advance,

Doug

Answer
Dear Doug,

While the expired Percocet will most likely not hurt you, it will probably not help much either. I would throw out your old percocet and get the new prescription filled.

Hope you feel better soon!

Best,
Dr. Tara Kompare, Pharm.D.
