Step 1
Compare the two items. All foods and medications, as well as cleaning products and items such as toothpaste or mouthwash, will have their ingredients listed. The ingredient listed first is the what makes up the bulk of the product. If the first two or three ingredients are the same, chances are you will not notice any difference between the generic version versus a brand name.

Step 2
Review your medications with your doctor or pharmacist to determine when you can substitute generic drugs for the more expensive brand name medications. In very few instances there are differences between a generic medication the brand name version. Allow a professional to make that choice for you.

Step 3
Purchase small amounts of a generic item to test it. Do this when buying such items as trash bags, lunch sacks or other items that do not have a list of ingredients. You may find that while the brand name may cost more to purchase, it may also perform better, justifying the extra expense.

Step 4
Compare the construction of the products, such as clothing, if you have the opportunity. Look at the quality of the sewing and fabric itself. Compare the weight and textures of the fabrics. If you can't find any appreciable difference, the generic is probably fine.
