All penicillin will go bad after a period of time, but it is actually better to keep liquid penicillin refrigerated. It is a good idea to check the expiration date on your penicillin, and dispose of it when it expires. Penicillin that has gone bad will not help you, and you should be careful with medications that are past their date.

Two years past the best-by is a long time. If the can is in good condition - not bulging or showing signs of leakage - the contents could be safe, but the quality is probably not so good. You might just replace it with new product.
About four to five days, properly refrigerated.
Check the expiration date on the container if you have one. If not, ask your local Pharmacist for advice. Taking out of date medications can do more harm than good, so it's best to know as much as you can about your meds.
