Maybe I'm parinoid, but that doesn't mean that I can read my doctors writing on my families prescriptions, or that I know all the generic names of the drug I'm suppose to be taking, or that the pharmicist really checked for drug interactions. This book will help clear things up. It lists every drug you could think of, with generic brands, has color pictures of hard to identify drugs.
Especially useful are the details on drug interations, including herbal medications (e.g. don't take St. Johns Wort with birth control pills) and common foods (e.g. some drugs do not mix will with grapefruit). Long also lists medical conditions that do not mix well with drugs (e.g. diabetes) as well as the risks of smoking and taking a certain drug, or the possible effects of the drug on pregnancy (very complete information here).
Even if you only take one or two Prescription drugs this is a good book to own, your health is worth it. Also, you can look up friends and relatives drugs and find out what they are taking them for, as well as possible side effects or harmful interactions. This would be a good gift for an elderly parent or friend.
