It’s a good idea to clean out your medicine cabinet twice a year. After the expiry date, medications start to lose their effectiveness, and so do products like sunscreen - so if you keep taking them you may not be getting the treatment or the protection you need. Some drugs even become toxic. Storing medications in the wrong place can also reduce their efficacy. Many of us keep drugs in the bathroom, but they really should be put in places that are not humid. A poll showed that in addition to prescription drugs, the most common expired products people found at home were Sunscreen, Cough & Cold medicine, Allergy pills and Vitamins.
