I just found some meds in the back of my cupboard that were my mums, they are codeine and paracetamol tablets, only thing the expiry dates are 2002 & 2005. Are they safe to take, or do they just lose potency? They are in original packets and were in a dark cupboard. I also take endone in 20mg doses when i can get it, but ran out today. Will the codeine be similar and how much should i take? The strength is 30mg codeine/500mg paracetamol. Thanks!
