Can I take Mucus Relief DM if it’s expired past a year or two? What do I do? ## Most medication don't become toxic, once they are expired, but they can begin to lose efficacy. Thus, the best thing to do would be to dispose of it, and obtain a new supply, if you still need to take it. The FDA's disposal methods state that you should put them in some undesirable substance, such as dirty cat litter, or coffee grounds, then place the mixture into a sealed container and dispose of it with your regular trash. What are the active ingredients in the medication you have?
