In the hospital setting, hydrogen peroxide is discarded 4 days after opening. It may still fizz and bubble, but it's actions are diminished. Buy the smallest bottle possible, and replace it frequently - it's cheap.

∙ 13y agoHydrogen Peroxide, or H2O2 can, over time, give up that extra oxygen atom and become H2O, or water. If the water is sealed, it mostly turns into old water and remains harmless, but also useless as an antiseptic. If improperly stored, the water can become a growth medium for all manner of life, just like any other water, which can be dangerous.
So yes -- it's rare but possible. Most of the time, it simply loses its antiseptic capabilities. This can happen fairly quickly once the bottle is opened; for maximum effectiveness, you should probably replace the bottle a few months after you open it.

∙ 14y agoHydrogen peroxide spontaneously decomposes on standing to water and oxygen gas. This decomposition causes the hydrogen peroxide to lose most of its oxidizing and sterilizing power, because the oxygen usually escapes to the atmosphere, and water is not a strong oxidant or sterilizer. For this reason, at least partial loss of hydrogen peroxide's most commonly used qualities, it is often said to "expire", but this does not mean that it disappears, and if the oxygen is retained, the product water and oxygen will have the same mass as the original hydrogen peroxide.

Can you use peroxide in your ear?
Yes you can although you have to be triple sure that your ear drum is not punctured or burst. You have to consult a doctor to find that out. And be sure you don't have a solid ear wax plug where the hydrogen can wiggle its way behind and with no room left to expand it can damage your earIf you are sure it is not punctured and you don't have an ear wax plug, you can put a few drops of hydrogen peroxide in the ear. This will give you a fizzing sound. After a few minutes take a clean wash cloth and turn your head over to drain the peroxide. Then put some alcohol in the ear to dry it out. Make sure you get out all the peroxide because 'left overs' will make your ears fizz for a long time
