Longevity really depends on the drug and the conditions that it's stored in. Never take antibiotics that have expired. Liquid forms should probably be tossed out when they expire as well. Usually, the potency of solid drugs will decrease very slowly over time depending on storage conditions; most drugs will not become toxic (except some antibiotics). Factors such as heat, humidity, exposure to air, exposure to light, and perhaps others can affect drug longevity.
