An advance directive is a legal form that describes the kinds of medical care you want to receive if something happens to you and you can't speak for yourself. It tells your family and your doctor what to do if you're badly hurt or have a serious illness that keeps you from saying what you want.
The two main types of advance directives are a living will and a medical power of attorney.
Some people are able to split their pills in half in order to save money on prescription drugs. If your doctor can double your normal dose, and you split the pills, you may be able to get a 2-month supply of medicine for the price of one.
But many medications cannot be split safely. The FDA has issued warnings about the risks. So have professional societies representing pharmacists and doctors. This article looks at when pill splitting is safe, and when it’s not.
A living will makes clear the kinds of medical care you want to receive if you get seriously hurt or ill and can't make your own decisions. It describes your choices for care and how you want them carried out if you're near the end of your life or are in the hospital with a serious illness. If you get better and can speak for yourself again, you can stop or say "no" to treatment at any time. If you have a living will, your choices will be honored. A living will is also called a treatment directive.
Medical power of attorney
A medical power of attorney lets you name a person to make treatment decisions for you when you can't speak for yourself. This person is called a health care agent or health care proxy. Some states may limit what your health care agent can decide for you. In a few states, he or she can speak for you right away and at any time that you don't want to make choices for yourself. He or she can also use your living will and what he or she knows about you to help guide your care.
When you choose a health care agent, select a person you trust to make medical decisions for you. For more information, see the topic Choosing a Health Care Agent.
As long as you can still make your own decisions, your advance directive won't be used. You can change or cancel it at any time. Your health care agent will only make choices for you if you can't or don't want to decide for yourself.
