Would you believe that your bathroom medicine cabinet is the worst place to store your medicines? If that's the case, why did they call it a medicine cabinet in the first place? The reason is the medicine cabinet inside the bathroom tend to be humid and warm and drugs in this kind of environment speeds up a drug's breakdown process. Where should we store medicines and your top diet pills? Store these in a cool and dry place and of course, out of children's reach. I store the medicines in the pantry. If you have to keep them in the kitchen, make sure to store them far from heat-releasing appliances like the stove.
