For minor symptoms and illnesses that are common, it is wise to keep some medications in supply at home. Follow the manufacture's directions and warnings when using these products. Check the expiration date before using any product.
Improper storage shortens the effective date of the medicine.
Store medicines in a cool, dry area. The heat from kitchens and the moisture from bathrooms decrease the effectiveness of a medication. Store all medications out of reach of children. There are many other products available that may also be used for these medical conditions. The products listed are not necessarily superior to other available commercial products.
