The term "medicine cabinet" is an anachronism, because pharmacists say it's one of the last places medications should be stored. Why? Bathrooms (and often, kitchens) get too humid and warm for storing both prescription and over-the-counter drugs (including vitamins). Heat (over about 85 degrees, according to an article in The New York Times) can physically alter medicines, affecting their potency and possible making them dangerous. Especially susceptible, according to the Times article, are thyroid medications, birth control pills, insulin, seizure medications and anticoagulents. And any type of test strip is sensitive to humidity, making bathrooom storage a dicey choice for those as well.
