Does Rayos (prednisone) cause side effects?
- ulcerative colitis,
- Crohn's disease,
- systemic lupus,
- allergic reactions,
- severe psoriasis,
- idiopathic thrombocytopenic purpura,
- autoimmune hemolytic anemia,
- bronchitis, to prevent the body from rejecting transplanted organs, and
- as replacement therapy in patients whose adrenal glands are unable to produce sufficient amounts of cortisol.
Synthetic corticosteroids mimic the action of cortisol (hydrocortisone), the naturally-occurring corticosteroid produced in the body by the adrenal glands. Corticosteroids have many effects on the body, but they most often are used for their potent anti-inflammatory effects, particularly in those diseases and conditions in which the immune system plays an important role.
Prednisone is inactive in the body and, in order to be effective, first must be converted to prednisolone by enzymes in the liver. Therefore, prednisone may not work as effectively in people with liver disease whose ability to convert prednisone to prednisolone is impaired.
Common side effects of Rayos include
- retention of sodium and fluid,
- weight gain,
- high blood pressure,
- loss of potassium,
- muscle weakness,
- thinning skin,
- restlessness, and
- problems sleeping.
Serious side effects of Rayos include
- puffiness of the face (moon face),
- growth of facial hair,
- thinning and easy bruising of the skin,
- impaired wound healing,
- worsening of diabetes,
- irregular menses,
- rounding of the upper back ("buffalo hump"),
- obesity, growth retardation in children,
- anaphylaxis (severe allergic reactions like hives, itching, skin rash, swollen lips/tongue/face),
- vision changes,
- congestive heart failure,
- heart attack,
- pulmonary edema,
- fast heart rate,
- allergic dermatitis,
- low blood pressure,
- missed menstrual periods,
- new-onset diabetes,
- high blood sugar (hyperglycemia),
- amnesia, and
- psychiatric disturbances (depression, euphoria, insomnia, mood swings, personality changes, and psychotic behavior).
- Estrogens may reduce the action of enzymes in the liver that break down the active form of Rayos, prednisolone. As a result, the levels of prednisolone in the body may increase and lead to more frequent side effects.
- Phenytoin increases the activity of enzymes in the liver that break down Rayos and thereby may reduce the effectiveness of Rayos.
- The risk of high potassium levels in the blood increases when corticosteroids are combined with drugs that reduce potassium levels (for example, amphotericin B, diuretics), leading to serious side effects such as heart enlargement, heart arrhythmias and congestive heart failure.
- Corticosteroids may increase or decrease the response warfarin.
- The response to diabetes drugs may be reduced because Rayos increases blood glucose.
- Rayos may increase the risk of tendon rupture in patients treated with fluoroquinolone type antibiotics.
- Combining aspirin, ibuprofen, or other nonsteroidal anti-inflammatory drugs (NSAIDs) with corticosteroids increases the risk of stomach related side effects like ulcers.
- Barbiturates, carbamazepine, rifampin and other drugs that increase the activity of liver enzymes that breakdown Rayos may reduce blood levels of prednisone.
- Conversely, ketoconazole, itraconazole, ritonavir, indinavir, macrolide antibiotics, and other drugs that reduce the activity of liver enzymes that breakdown prednisone may increase blood levels of Rayos.
Corticosteroids cross the placenta into the fetus. Compared to other corticosteroids, however, Rayos is less likely to cross the placenta. Chronic use of corticosteroids during the first trimester of pregnancy may cause cleft palate.
Corticosteroids are secreted in breast milk and can cause side effects in the nursing infant. Rayos is less likely than other corticosteroids to be secreted in breast milk, but it may still pose a risk to the infant. Consult your doctor before breastfeeding.
What are the important side effects of Rayos (prednisone)?
Side effects of prednisone and other corticosteroids range from mild annoyances to serious, irreversible organ damage, and they occur more frequently with higher doses and more prolonged treatment.
Common side effects include:
- Retention of sodium (salt) and fluid
- Weight gain
- High blood pressure
- Loss of potassium
- Muscle weakness
- Thinning skin
- Problems sleeping
Serious side effects include:
- Puffiness of the face (moon face)
- Growth of facial hair
- Thinning and easy bruising of the skin
- Impaired wound healing
- Ulcers in the stomach and duodenum
- Worsening of diabetes
- Irregular menses
- Rounding of the upper back ("buffalo hump")
- Retardation of growth in children
- Anaphylaxis (severe allergic reactions like hives, itching, skin rash, swollen lips/tongue/face)
- Vision changes
- Congestive heart failure
- Heart attack
- Pulmonary edema
- Allergic dermatitis
- Low blood pressure
- Amenorrhea (lack of menstruation)
- Newly onset diabetes
This drug also causes psychiatric disturbances, which include:
Other possible serious side effects of this drug include:
Prednisone and diabetes: Prednisone is associated with new onset or manifestations of latent diabetes, and worsening of diabetes. Diabetics may require higher doses of diabetes medications while taking prednisone.
Allergic reaction: Some people may develop a severe allergic reaction (anaphylaxis) to prednisone that includes swelling of the airways (angioedema) that may result in shortness of breath or airway blockage.
Immune suppression: Prednisone suppresses the immune system and, therefore, increases the frequency or severity of infections and decreases the effectiveness of vaccines and antibiotics.
Osteoporosis: Prednisone may cause osteoporosis that results in fractures of bones. Patients taking long-term prednisone often receive supplements of calcium and vitamin D to counteract the effects on bones. Calcium and vitamin D probably are not enough, however, and treatment with bisphosphonates such as alendronate (Fosamax) and risedronate (Actonel) may be necessary. Calcitonin (Miacalcin) also is effective. The development of osteoporosis and the need for treatment can be monitored using bone density scans.
Adrenal insufficiency and weaning off prednisone: Prolonged use of prednisone and other corticosteroids causes the adrenal glands to atrophy (shrink) and stop producing the body's natural corticosteroid, cortisol.
Necrosis of hips and joints: A serious complication of long-term use of corticosteroids is aseptic necrosis of the hip joints. Aseptic necrosis is a condition in which there is death and degeneration of the hip bone. It is a painful condition that ultimately can lead to the need for surgical replacement of the hip. Aseptic necrosis also has been reported in the knee joints. The estimated incidence of aseptic necrosis among long-term users of corticosteroids is 3%-4%. Patients taking corticosteroids who develop pain in the hips or knees should report the pain to their doctors promptly.

Reproductive: Alteration in motility and number of spermatozoa
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of Rayos was evaluated in 375 rheumatoid arthritis patients in two controlled trials. Patients treated with Rayos ranged in age from 20 to 80 years (median age 56 years), with 85% female, 99% Caucasian, 1% African-American, and < 1% Asian.
Patients received Rayos 3 mg to 10 mg once daily at 10 pm; the majority (84%) received ≥ 5 mg. The clinical trial experience did not raise new safety concerns beyond those already established for immediate-release prednisone.
Adverse reactions have been identified during post-approval use of Rayos. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The postmarketing experience has not raised new safety concerns beyond those already established for immediate-release prednisone.
What drugs interact with Rayos (prednisone)?
Aminoglutethimide may lead to loss of corticosteroid-induced adrenal suppression.
Amphotericin B Injection
There have been cases reported in which concomitant use of Amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure.
Concomitant use of anticholinesterase agents and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating corticosteroid therapy.
Co-administration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Therefore, coagulation indices should be monitored frequently to maintain the desired anticoagulant effect.
Because corticosteroids may increase blood glucose concentrations, dosage adjustments of antidiabetic agents may be required.
Serum concentrations of isoniazid may be decreased.
CYP 3A4 Inducers (e.g., Barbiturates, Phenytoin, Carbamazepine, and Rifampin)
Drugs such as barbiturates, phenytoin, ephedrine, and rifampin, which induce hepatic microsomal drug metabolizing enzyme activity may enhance the metabolism of corticosteroids and require that the dosage of the corticosteroid be increased.
CYP 3A4 Inhibitors (e.g., Ketoconazole, Macrolide Antibiotics)
Ketoconazole has been reported to decrease the metabolism of certain corticosteroids by up to 60% leading to increased risk of corticosteroid side effects.
Cholestyramine may increase the clearance of corticosteroids.
Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently. Convulsions have been reported with this concurrent use.
Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia.
Estrogens, Including Oral Contraceptives
Estrogens may decrease the hepatic metabolism of certain corticosteroids, thereby increasing their effect.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDS) Including Aspirin and Salicylates
Concomitant use of aspirin or other nonsteroidal anti-inflammatory drugs and corticosteroids increases the risk of gastrointestinal side effects. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The clearance of salicylates may be increased with concurrent use of corticosteroids; this could lead to decreased salicylate serum levels or increase the risk of salicylate toxicity when corticosteroid is withdrawn.
Potassium-Depleting Agents (e.g., Diuretics, Amphotericin B)
When corticosteroids are administered concomitantly with potassium-depleting agents, patients should be observed closely for development of hypokalemia.
Corticosteroids may suppress reactions to skin tests.
Toxoids and Live or Attenuated Vaccines
Patients on corticosteroid therapy may exhibit a diminished response to toxoids and live or inactivated vaccines due to inhibition of antibody response. Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines. Routine administration of vaccines or toxoids should be deferred until corticosteroid therapy is discontinued if possible.
Rayos (prednisone) is a corticosteroid used to treat a wide variety of conditions including arthritis, ulcerative colitis, Crohn's disease, systemic lupus, allergic reactions, asthma, severe psoriasis, leukemias, lymphomas, idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, and bronchitis. Common side effects of Rayos include retention of sodium and fluid, weight gain, high blood pressure, loss of potassium, headache, muscle weakness, nausea, vomiting, acne, thinning skin, restlessness, and problems sleeping. Compared to other corticosteroids, Rayos is less likely to cross the placenta in pregnant women. Rayos is less likely than other corticosteroids to be secreted in breast milk, but it may still pose a risk to the infant.

Related Disease Conditions
Psoriasis is a long-term skin condition that may cause large plaques of red, raised skin, flakes of dry skin, and skin scales. There are several types of psoriasis, including psoriasis vulgaris, guttate psoriasis, inverse psoriasis, and pustular psoriasis. Symptoms vary depending on the type of psoriasis the patient has. Treatment of psoriasis may include creams, lotions, oral medications, injections and infusions of biologics, and light therapy. There is no cure for psoriasis.
Buildup of uric acid crystals in a joint causes gouty arthritis. Symptoms and signs include joint pain, swelling, heat, and redness, typically of a single joint. Gout may be treated with diet and lifestyle changes, as well as medication.
Rheumatoid Arthritis (RA)
Rheumatoid arthritis (RA) is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease. The 16 characteristic early RA signs and symptoms include the following. Anemia Both sides of the body affected (symmetric) Depression Fatigue Fever Joint deformity Joint pain Joint redness Joint stiffness Joint swelling Joint tenderness Joint warmth Limping Loss of joint function Loss of joint range of motion Many joints affected (polyarthritis)
16 Early Signs and Symptoms of Rheumatoid Arthritis (RA)
Early RA symptoms and signs vary differently from person to person. The most common body parts that are initially affected by RA include the small joints of the hands, wrists, and feet, and the knees and hip joints. Joint inflammation causes stiffness. Warmth, redness, and pain may vary in degree.
Arthritis (Joint Inflammation)
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis, including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.

Scalp Psoriasis (Psoriasis of the Scalp)
Scalp psoriasis causes red, raised, scaly patches that may extend from the scalp to the forehead and the back of the neck and ears. Symptoms and signs include itching, hair loss, flaking, silvery scales, and red plaques. Treatment includes topical medicated shampoos, creams, gels, oils, ointments, and soaps, medications, and light therapy.
Psoriatic arthritis is a disease that causes skin and joint inflammation. Symptoms and signs include painful, stiff, and swollen joints, tendinitis, and organ inflammation. Treatment involves anti-inflammatory medications and exercise.
Rheumatoid Arthritis vs. Fibromyalgia
Though rheumatoid arthritis (RA) and fibromyalgia have similar symptoms, RA is an autoimmune disease and fibromyalgia is a chronic pain syndrome. RA symptoms include joint redness, swelling, and pain that lasts more than six weeks. Fibromyalgia symptoms include widespread pain, tingling feet or hands, depression, and bowel irritability. Home remedies for both include stress reduction, exercise, and getting enough sleep.
Reactive arthritis is a chronic, systemic rheumatic disease characterized by three conditions, including conjunctivitis, joint inflammation, and genital, urinary, or gastrointestinal system inflammation. Inflammation leads to pain, swelling, warmth, redness, and stiffness of the affected joints. Non-joint areas may experience irritation and pain. Treatment for reactive arthritis depends on which area of the body is affected. Joint inflammation is treated with anti-inflammatory medications.
Juvenile Rheumatoid Arthritis (JRA)
Juvenile rheumatoid arthritis (JRA) annually affects one child in every thousand. There are six types of JRA. Treatment of juvenile arthritis depends upon the type the child has and should focus on treating the symptoms that manifest.
Is Psoriasis Contagious?
Psoriasis is an incurable skin disease that causes reddish patches of skin topped with a thick layer of dry silvery scales. Psoriasis cannot spread and is not contagious.
Osteoarthritis vs. Rheumatoid Arthritis
Osteoarthritis (OA) and rheumatoid arthritis (RA) are chronic joint disorders. RA is also an autoimmune disease. OA and RA symptoms and signs include joint pain, warmth, and tenderness. Over-the-counter pain relievers treat both diseases. There are several prescription medications that treat RA.
What Is the Main Cause of Osteoarthritis?
Osteoarthritis (OA) is a chronic degenerative disease of the joints affecting middle-aged and elderly people. It involves the breakdown of cartilage and associated inflammatory changes in the adjacent bone. It is a leading cause of chronic disability, affecting 30 million people in the United States alone.
Osteoarthritis vs. Osteoporosis Differences and Similarities
Arthritis is defined as painful inflammation and joint stiffness. Osteoarthritis is a type of arthritis and the most common cause of chronic joint pain, affecting over 25 million Americans. Osteoarthritis is a type of arthritis that involves the entire joint. Osteoporosis is not a type of arthritis. It is a disease that mainly is caused by a loss of bone tissue that is not limited to the joint areas. It is possible for one person to have both osteoarthritis and osteoporosis. The differences in the signs and symptoms of osteoarthritis and osteoporosis include; pain, stiffness, and joint swelling, joint deformity, crackle sounds when the joint is moving, and walking with a limp. Osteoporosis is called the "silent disease" because it can progress for years without signs and symptoms before it is diagnosed, severe back pain, bone fractures, height loss, and difficulty or inability to walk. The differences in the causes of osteoarthritis and osteoporosis are that osteoarthritis usually is caused by wear and tear on the joints. Osteoporosis usually is caused by one or more underlying problems, for example, calcium and vitamin D deficiencies. Treatment for osteoarthritis and osteoporosis are not the same. There is no cure for osteoarthritis or osteoporosis.
What Is the Main Cause of Rheumatoid Arthritis?
Rheumatoid arthritis is a chronic inflammatory disease characterized by pain and inflammation in joints, typically of the hands and feet. It is an autoimmune disease in which the immune system of the body attacks its own healthy cells, resulting in inflammation of the membrane lining the joints and damage to joint tissue.
What Is the Best Treatment for Psoriasis?
Psoriasis is an incurable chronic autoimmune disorder of the skin that causes patches of thick, flaky, scaly skin, mostly around the scalp, knees, and elbows, though any skin surface may be involved. Some people experience only small patches while others have red, inflamed skin and think scaly patches all over the body. The exact cause of psoriasis is not clear, but it isn’t contagious.
Rheumatoid Arthritis vs. Arthritis
Arthritis is a general term used to describe joint disease. Rheumatoid arthritis (RA) is a type of arthritis in which the body’s immune system mistakenly attacks the joints, causing chronic inflammation.
What Is the Main Cause of Psoriasis?
Psoriasis is a non-contagious skin disease in which the skin cells grow in numbers faster than normal, producing rashes on the body. Normally, the cells on the surface of the skin are shed as new cells grow beneath. In psoriasis, the swift build-up of skin cells collects on the surface of the skin as scales or plaques. The exact cause of psoriasis is not completely understood. It appears to involve an interplay between a person’s genes, immune system and environment.
