It depends on the medicine. I have been told by a pharmacist that liquids expire, but normal pills do not.What do you do about prescription medicines that you must take daily?
Stock piling them would just end up with them going out of date.
What do you do?
ask your doctor what he/she can do to help.....................
I would argue that many diseases that are treated by medication would be better to be prevented or treated through diet and exercise (diabetes, cholesterol problems, high blood pressure, etc.) I'm not soapboxing here, just providing my own viewpoint on how you can help yourself without the meds.
Good luck.
BTW, yes I am a pharmacist.
