Uses for Rayos
Prednisone provides relief for inflamed areas of the body. It is used to treat a number of different conditions, such as inflammation (swelling), severe allergies, adrenal problems, arthritis, asthma, blood or bone marrow problems, endocrine problems, eye or vision problems, stomach or bowel problems, lupus, skin conditions, kidney problems, ulcerative colitis, and flare-ups of multiple sclerosis. Prednisone is a corticosteroid (cortisone-like medicine or steroid). It works on the immune system to help relieve swelling, redness, itching, and allergic reactions.
This medicine is available only with your doctor's prescription.
Before using Rayos
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of prednisone in children. However, pediatric patients are more likely to have slower growth and bone problems if prednisone is used for a long time. Recommended doses should not be exceeded, and the patient should be carefully monitored during therapy.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of prednisone in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for elderly patients receiving prednisone.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Precautions while using Rayos
If you will be taking this medicine for a long time, it is very important that your doctor check you at regular visits for any unwanted effects that may be caused by this medicine. Blood or urine tests may be needed to check for unwanted effects.
Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using this medicine, tell your doctor right away.
If you are using this medicine for a long time, tell your doctor about any extra stress or anxiety in your life, including other health concerns and emotional stress. Your dose of this medicine might need to be changed for a short time while you have extra stress.
Using too much of this medicine or using it for a long time may increase your risk of having adrenal gland problems. Talk to your doctor right away if you have more than one of these symptoms while you are using this medicine: blurred vision, dizziness or fainting, a fast, irregular, or pounding heartbeat, increased thirst or urination, irritability, or unusual tiredness or weakness.
This medicine may cause you to get more infections than usual. Avoid people who are sick or have infections and wash your hands often. If you are exposed to chickenpox or measles, tell your doctor right away. If you start to have a fever, chills, sore throat, or any other sign of an infection, call your doctor right away.
Check with your doctor right away if blurred vision, difficulty in reading, eye pain, or any other change in vision occurs during or after treatment. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
While you are being treated with prednisone, do not have any immunizations (vaccines) without your doctor's approval. Prednisone may lower your body's resistance and the vaccine may not work as well or you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live virus vaccines because there is a chance they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.
This medicine may cause changes in mood or behavior for some patients. Tell your doctor right away if you have depression, mood swings, a false or unusual sense of well-being, trouble with sleeping, or personality changes while taking this medicine.
This medicine might cause thinning of the bones (osteoporosis) or slow growth in children if used for a long time. Tell your doctor if you have any bone pain or if you have an increased risk for osteoporosis. If your child is using this medicine, tell the doctor if you think your child is not growing properly.
Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine may affect the results of certain skin tests.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
