does keflex need to be refrigerated
<br /><br /><br /><br /><br /> Nothing, Keflex (brand name) Cephalixin (generic) is anti-biotic and unless it's a liquid (and even then it would say on the bottle if it needs to be refrigerated) they usually don't need to be refrigerated. If you are talking about the liquid formulation, it will go bad very quickly. It will survive being left out over night at room temperature, but if a 24 hour period has passed, it needs to be thrown away as the cephalexin (which is the correct spelling) slowly becomes hydrolyzed by water, and later destroyed.
