If so, does it say it on the bottle? After how many years does it expire?

Yes. If its after a year, then I would throw it out.  Usually there is an expiration date somewhere on the bottle. But it doesn't work if it is old.  Hope this helps!

(m)\n\nExpired medicines often don't work as well, and they can even be harmful. To make sure that you don't accidentally take an out-of-date medication, you should clean out your medicine cabinet every year, throwing away: \n\nAny medication that has changed color or formed a residue,\n \nAspirin or acetaminophen that is crumbly or smells strange,\n \nHydrogen peroxide that no longer bubbles when applied as a disinfectant, and \n\nEye drops that have expired.

=it drives me crazy as does the word "clearly.  It should have expired a couple of years ago but it is still going strong. It is used often in the news as well!  I can appreciate what you are saying.

I don't care if I'm the only person who thinks this... but I wish it wasn't like that.\nCrimes shouldn't have an expiration.

Usually they are valid for one year from the date of issue. The only exception to this rule is for pain meds...they expire sooner. Not sure if it is 3 months or 6 months for pain meds. \n\nCall your pharmacy and ask them specifics. You don't have to give your name. Just ask about the expiration dates. \n\nGood luck! Hope you feel better.

It will be detectable for approximately 6 months after the last intake. As for the effects themselves, the direct ones should pass after a week. The more lasting effects (such as memory problems) caused by long-term usage should disappear within a couple of months.

Bottled water will not go off if it hasn`t been opened ,at least not off in making you ill .If it`s very old there`s a chance of it not tasting very nice .\nIf you mean in a bottle that you have put water in your self it`s likely theres bacteria in the water and it will only be good for a day or two ,and eventually will be very dangerous to drink

One-time use usually shows up for 24-72 hours.  Habitual use can stay in your blood up to 2 months, according to the charts at my work.  I guess smoking it "occasionally" would fall somewhere in between.  Tobacco and alcohol will not show up because they don't test for them.

You should really be careful when taking medication that has expired!  In your case, the tylenol had lost it's effects.  You should have noticed a vinager(sp) smell, that's how you know when they aren't good anymore.  \n\nYou can keep tylenol from going bad if you usually buy a big bottle by putting about 10 of them in a smaller bottle.  When you keep opening up the bottle the air that gets inside can make them go bad.

I am quite not sure of what xtc you are referring to but I am certain that if it is a kind of drug or substance, it is purely an urban legend. Everything in the body fluids undergoes process of absorption, metabolism and elimination so I cannot think of any substance that won't be eliminated from a body for a lifetime.☺

You will be able to use it after the expiration date, No problem.\nBut if you use it after 10 or 20 months that will be the problem...\nPlz choose me as best answer!!

For the most part yes, as long as it is reasonable fresh.  For thousands of years this was the only people drank it.  Pasteurization extends the shelf life of milk substantially, making it safe to store and transport over distances.
