Yes
Yes, the expiration date does matter. Isopropyl alcohol (standard rubbing alcohol) will oxidize into acetone. This happens slowly over time, and the expiration date is the point at which the rubbing alcohol is less than effective. The good news is that alcohol is like a dollar and you can find it just about anywhere! When it comes to preventing an infection (instead of paying medical bills!) it is worth having something that you can trust and isn't expired.
As with ALL medications, there is an EXPIRATION DATE, so YES it can go bad and should not be used past the expiration date. I forget what the exact percentage is, but liquid hydrocodone also has alcohol (not rubbing alcohol) as an ingredient.
No, I have used rubbing compound that was 10 years old and it worked just like it was new.
It is not recommended that you take a medication after it's expiration date. Therefore nutrofurantoin-macro will not still be effective for treating an UTI after the expiration date.

no
Hand sanitizer may become less effective over time as the alcohol content can evaporate or degrade, reducing its ability to kill germs. An expiration date helps ensure that the product is still safe and effective to use. It is always recommended to check the expiration date before using hand sanitizer.
It is never good to use any medication after an expiration date, if one is listed.
There is no expiration date! There is a date of manufacture under the brim. It really depends on the condition, whether it is still OK.
The expiration or best-use-by dates are for unopened packages.
Read carefully. It is NOT an expiration date. Only baby food has expiration dates. It is "best by" or "use by" recommendations. Extracts have alcohol in them. Unless the lid was off and the alcohol evaporated nothing goes wrong. With time the taste of the extract MAY degrade but it does not expire.
