Many people store their medications in the bathroom. But this popular spot is actually one of the worst places to keep medicine. Bathroom cabinets tend to be warm and humid, an environment that speeds up a drug's breakdown process.
This is especially true for tablets and capsules. Being exposed to heat and moisture can make medicines less potent before their expiration date. For example, a warm, muggy environment can cause aspirin tablets to break down into acetic acid (vinegar) and salicylic acid, both of which can irritate the stomach.
Instead, keep medicines in a cool, dry, secure place out of a child's reach. You may need to use a locked cabinet or box. If you must keep your medicines in the bathroom, keep the containers tightly closed. If you store medicines in a kitchen, keep them away from the stove, sink, and any hot appliances.
Consider refilling your prescriptions each month, instead of every 3 months to make sure they are still potent.
