Rayos (prednisone) is a corticosteroid that reduces inflammation in the body, and also suppresses your immune system.
Rayos is used to treat many different conditions such as hormonal disorders, skin diseases, arthritis, lupus, psoriasis, allergic conditions, ulcerative colitis, Crohn's disease, eye diseases, lung diseases, asthma, tuberculosis, blood cell disorders, kidney disorders, leukemia, lymphoma, multiple sclerosis, organ transplant rejection, swelling from a brain tumor or injury.
Rayos may also be used for purposes not listed in this medication guide.
You should avoid taking Rayos if you have a fungal infection that requires oral antifungals. Topical antifungals may not be an issue, but always let your doctor know what medicines you’re taking before starting Rayos.
Corticosteroid medication can weaken your immune system, making it easier for you to get an infection. Avoid being near people who are sick or have infections. Do not receive a "live" vaccine while using prednisone.
Call your doctor at once if you have shortness of breath, severe pain in your upper stomach, bloody or tarry stools, severe depression, changes in personality or behavior, vision problems, or eye pain.
You should not stop using Rayos suddenly. Follow your doctor's instructions about tapering your dose.
You should not use Rayos if you are allergic to prednisone, or if you have a fungal infection anywhere in your body.
Corticosteroid medication can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have. Tell your doctor about any illness or infection you've had within the past several weeks.
To make sure Rayos is safe for you, tell your doctor if you have ever had:
heart problems, high blood pressure, or a heart attack;
glaucoma or cataracts;
herpes infection of the eyes;
past or present tuberculosis;
a parasite infection that causes diarrhea (such as threadworms);
any illness that causes diarrhea;
underactive thyroid;
diabetes;
a stomach ulcer, diverticulitis;
a colostomy or ileostomy;
osteoporosis or low bone mineral density (steroid medication can increase your risk of bone loss);
low levels of calcium or potassium in your blood;
cirrhosis or other liver disease;
mental illness or psychosis; or
a muscle disorder such as myasthenia gravis.
Long-term use of corticosteroids may lead to bone loss (osteoporosis), especially if you smoke or drink alcohol, if you do not exercise, or if you do not get enough vitamin D or calcium in your diet.
It is not known whether prednisone will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
You should not breastfeed while using Rayos.
Take Rayos exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.
Rayos is taken daily or every other day, depending on the condition being treated. You may need to take the medicine at a certain time of day. Follow your doctor's instructions about when and how often to take this medicine.
Take with food if Rayos upsets your stomach.
Swallow the Rayos delayed-release tablet whole and do not crush, chew, or break it.
Prednisone can weaken (suppress) your immune system, and you may get an infection more easily. Call your doctor if you have signs of infection (fever, weakness, cold or flu symptoms, skin sores, diarrhea, frequent or recurring illness).
If you have major surgery or a severe injury or infection, your prednisone dose needs may change. Make sure any doctor caring for you knows you are using this medicine.
If you use this medicine long-term, you may need medical tests and vision exams.
In case of emergency, wear or carry medical identification to let others know you use a steroid.
You should not stop using Rayos suddenly. Follow your doctor's instructions about tapering your dose.
Store at room temperature away from moisture, heat, and light.
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
High doses or long-term use of Rayos can lead to thinning skin, easy bruising, changes in body fat (especially in your face, neck, back, and waist), increased acne or facial hair, menstrual problems, impotence, or loss of interest in sex.
Do not receive a "live" vaccine while using Rayos. The vaccine may not work as well and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chickenpox or measles. These conditions can be serious or even fatal in people who are using steroid medicine.
Avoid drinking alcohol.
Get emergency medical help if you have signs of an allergic reaction to Rayos: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have:
muscle pain or weakness;
blurred vision, tunnel vision, eye pain, or seeing halos around lights;
severe depression, changes in personality, unusual thoughts or behavior;
bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds;
swelling, rapid weight gain, feeling short of breath;
irregular heartbeats;
severe headache, pounding in your neck or ears;
decreased adrenal gland hormones - muscle weakness, tiredness, diarrhea, nausea, menstrual changes, skin discoloration, craving salty foods, and feeling light-headed; or
low potassium level - leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling, muscle weakness or limp feeling.
Prednisone can affect growth in children. Tell your doctor if your child is not growing at a normal rate while using this medicine.
Common Rayos side effects may include:
weight gain (especially in your face or your upper back and torso);
increased appetite;
mood changes, trouble sleeping;
changes in your menstrual periods;
problems with memory or thought;
muscle or joint pain;
weakness;
headache, dizziness, spinning sensation;
nausea, bloating, loss of appetite;
slow wound healing; or
acne, increased sweating, thinning skin, bruising, pinpoint spots under your skin.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.
Tell your doctor about all your current medicines. Many drugs can interact with prednisone, especially:
bupropion;
cyclosporine;
digoxin;
ketoconazole;
an antibiotic;
birth control pills or hormone replacement therapy;
a diuretic or "water pill";
insulin or oral diabetes medicine;
a blood thinner - warfarin, Coumadin, Jantoven; or
NSAIDs (nonsteroidal anti-inflammatory drugs) - aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
This list is not complete and many other drugs may interact with prednisone. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use Rayos only for the indication prescribed.
Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances.
