How long can you store betadine once it has been open?

Once opened, Betadine (povidone-iodine) should be stored in a cool, dry place and typically can be used for up to three years, as indicated by the expiration date on the packaging. However, it's important to check for any changes in color, consistency, or odor before use, as these may indicate that the solution has degraded. Always consult the manufacturer's guidelines for the most accurate information regarding storage and shelf life. If in doubt, it's best to discard it and obtain a new bottle.
