WHY is this medicine prescribed?
Prednisone is used alone or with other medications to treat the symptoms of low corticosteroid levels (lack of certain substances that are usually produced by the body and are needed for normal body functioning). Prednisone is also used to treat other conditions in patients with normal corticosteroid levels. These conditions include certain types of arthritis; severe allergic reactions; multiple sclerosis (a disease in which the nerves do not function properly); lupus (a disease in which the body attacks many of its own organs); and certain conditions that affect the lungs, skin, eyes, kidneys blood, thyroid, stomach, and intestines. Prednisone is also sometimes used to treat the symptoms of certain types of cancer. Prednisone is in a class of medications called corticosteroids. It works to treat patients with low levels of corticosteroids by replacing steroids that are normally produced naturally by the body. It works to treat other conditions by reducing swelling and redness and by changing the way the immune system works.
Are there OTHER USES for this medicine?
Prednisone is also sometimes used with antibiotics to treat a certain type of pneumonia in patients with acquired immunodeficiency syndrome (AIDS). Talk to your doctor about the risks of using this drug for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
HOW should this medicine be used?
Prednisone comes as a tablet, delayed-release tablet, as a solution (liquid), and as a concentrated solution to take by mouth. Prednisone is usually taken with food one to four times a day or once every other day. Your doctor will probably tell you to take your dose(s) of prednisone at certain time(s) of day every day. Your personal dosing schedule will depend on your condition and on how you respond to treatment. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take prednisone exactly as directed. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.
If you are taking the concentrated solution, use the specially marked dropper that comes with the medication to measure your dose. You may mix the concentrated solution with juice, other flavored liquids, or soft foods such as applesauce.
Swallow the delayed-release tablet whole; do not chew or crush it.
Your doctor may change your dose of prednisone often during your treatment to be sure that you are always taking the lowest dose that works for you. Your doctor may also need to change your dose if you experience unusual stress on your body such as surgery, illness, infection, or a severe asthma attack. Tell your doctor if your symptoms improve or get worse or if you get sick or have any changes in your health during your treatment.
If you are taking prednisone to treat a long-lasting disease, the medication may help control your condition but will not cure it. Continue to take prednisone even if you feel well. Do not stop taking prednisone without talking to your doctor. If you suddenly stop taking prednisone, your body may not have enough natural steroids to function normally. This may cause symptoms such as extreme tiredness, weakness, slowed movements, upset stomach, weight loss, changes in skin color, sores in the mouth, and craving for salt. Call your doctor if you experience these or other unusual symptoms while you are taking decreasing doses of prednisone or after you stop taking the medication.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. [WEB]
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ([WEB]) for more information if you do not have access to a take-back program.
What should I do in case of OVERDOSE?
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at [WEB]. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
What OTHER INFORMATION should I know?

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
