What is prednisone (Prednisone Intensol, Rayos)?
Prednisone is a drug that belongs to the corticosteroid drug class, and is an anti-inflammatory and immune system suppressant. It's used to treat a variety of diseases and conditions, for example: inflammatory bowel disease (Crohn's disease and ulcerative colitis), lupus, asthma, cancers, and several types of arthritis.
Common side effects are weight gain, headache, fluid retention, and muscle weakness. Other effects and adverse events include glaucoma, cataracts, obesity, facial hair growth, moon face, and growth retardation in children. This medicine also causes psychiatric problems, for example: depression, insomnia, mood swings, personality changes, and psychotic behavior. Serious side effects include reactions to diabetes drugs, infections, and necrosis of the hips and joints.
Corticosteroids like prednisone, have many drug interactions; examples include: estrogens, phenytoin (Dilantin), diuretics, warfarin (Coumadin, Jantoven), alcohol, and diabetes drugs. Prednisone is available as tablets of 1, 2.5, 10, 20, and 50 mg; extended release tablets of 1, 2, and 5mg; and oral solution of 5mg/5ml. It's use during the first trimester of pregnancy may cause cleft palate. This medicine is secreted in breast milk and can cause side effects in infants who are nursing. You should not stop taking prednisone abruptly because it can cause withdrawal symptoms and adrenal failure.

- Loss of potassium
- Muscle weakness
- Thinning skin
- Problems sleeping

- Heart attack
- Pulmonary edema
- Allergic dermatitis

- 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.
