What are the differences between prednisone and prednisolone?
- Prednisone and prednisolone are synthetic corticosteroids used for suppressing the immune system and inflammation. Both drugs are used to treat many conditions including arthritis, colitis, asthma, bronchitis, skin problems, and allergies.
- Corticosteroids including prednisone and prednisolone are commonly used to suppress the immune system and prevent the body from rejecting transplanted organs.
- Brand names of prednisone include Prednisone Intensol and Rayos. Brand names of prednisolone include Flo-Pred, Pediapred, Orapred, and Orapred ODT.
- Common side effects of both prednisone and prednisolone include retention of sodium (salt) and fluid, weight gain, high blood pressure (hypertension), potassium loss, headache, muscle weakness, nausea, vomiting, acne, thinning skin, restlessness, and psychiatric disturbances (depression, euphoria, insomnia, mood swings, personality changes, and psychotic behavior).
- Prolonged use of prednisone or prednisolone can depress the ability of body's adrenal glands to produce corticosteroids. Abruptly stopping prednisone or prednisolone can cause symptoms of corticosteroid insufficiency, such as nausea, vomiting, weakness, fatigue, decreased appetite, weight loss, diarrhea, abdominal pain, and shock. Weaning off prednisone or prednisolone should occur gradually so that the adrenal glands have time to recover and resume production of cortisol.
What are prednisone and prednisolone?
What are the side effects of prednisone and prednisolone?
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.
Prednisolone side effects depend on the dose, the duration and the frequency of administration. Short courses of prednisolone - days to a week or two - are usually well tolerated with few and mild side effects. Long-term, high doses of prednisolone will usually produce predictable and potentially serious side effects. Whenever possible, the lowest effective doses of prednisolone should be used for the shortest length of time to minimize side effects. Alternate day dosing can also help reduce side effects.
Side effects of prednisolone and other corticosteroids range from mild annoyances to serious irreversible damage. Side effects include
- fluid retention,
- weight gain,
- high blood pressure,
- potassium loss,
- muscle weakness,
- puffiness of and hair growth on the face,
- thinning and easy bruising of the skin,
- peptic ulceration,
- worsening of diabetes,
- irregular menses,
- growth retardation in children,
- convulsions, and
- psychic disturbances. (Psychic disturbances can include depression, euphoria, insomnia, mood swings, personality changes, and even psychotic behavior.)
Prolonged use of prednisolone can depress the ability of body's adrenal glands to produce corticosteroids. Abruptly stopping prednisolone can cause symptoms of corticosteroid insufficiency, with accompanying nausea/a>, vomiting, and even shock. Therefore, withdrawal of prednisolone is usually accomplished by gradual tapering. Gradually tapering prednisolone not only minimizes the symptoms of corticosteroid insufficiency, but it also reduces the risk of an abrupt flare of the disease under treatment.
Prednisolone and other corticosteroids can mask signs of infection and impair the body's natural immune response to infection. Patients on corticosteroids are more susceptible to infections and can develop more serious infections than healthy individuals. For instance, chickenpox and measles viruses can produce serious and even fatal illnesses in patients on high doses of prednisolone. Live virus vaccines, such as smallpox vaccine, should be avoided in patients taking high doses of prednisolone, since even vaccine viruses may cause disease in patients taking prednisolone. Some infectious organisms, such as tuberculosis (TB) and malaria, can remain dormant in a patient for years. Prednisolone and other corticosteroids can reactivate dormant infections in these patients and cause serious illnesses. Patients with dormant TB may require anti-TB medications while undergoing prolonged corticosteroid treatment.
By interfering with the patient's immune response, prednisolone can impede the effectiveness of vaccinations. Prednisolone can also interfere with the tuberculin skin test and cause false negative results in patients with tuberculosis infection.
Prednisolone impairs calcium absorption and new bone formation. Patients on prolonged treatment with prednisolone and other corticosteroids can develop thinning of bone (osteoporosis) and an increased risk of bone fractures. Supplemental calcium and vitamin D are encouraged to slow this process of bone thinning. In some patients, medications used to treat osteoporosis may be prescribed. In rare individuals, destruction of large joints (osteonecrosis) can occur while undergoing treatment with prednisolone or other corticosteroids. These patients experience severe pain in the involved joints, and can require replacement of joints. The reason behind such destruction is not clear.
What is the dosage of prednisone vs. prednisolone?
The initial dosage of prednisone varies depending on the condition being treated and the age of the patient.
- It's recommended that you take this medication with food.
- The starting dose may be from 5 mg to 60 mg per day, and often is adjusted based on the response of the disease or condition being treated.
- Corticosteroids typically do not produce immediate effects and must be used for several days before maximal effects are seen. It may take much longer before conditions respond to treatment.
- When prednisone is discontinued after a period of prolonged therapy, the dose of prednisone must be tapered (lowered gradually) to allow the adrenal glands time to recover.
- Dosage requirements of corticosteroids vary among individuals and the diseases being treated. The usual starting dose range is 5 mg to 60 mg daily depending on the disease being treated.
- Doses are adjusted based on patient response. In general, the lowest possible effective dose is used. Corticosteroids given in multiple doses throughout the day are more effective, but also more toxic than alternate-day therapy where twice the daily dose is administered every other morning.
- Prednisolone should be taken with food to reduce irritation of the stomach and intestines.
What drugs interact with prednisone and prednisolone?
Prednisone interacts with many drugs, examples include:
- Prednisone may interact with estrogens and phenytoin (Dilantin). Estrogens may reduce the action of enzymes in the liver that break down (eliminate) the active form of prednisone, 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 (eliminate) prednisone and thereby may reduce the effectiveness of prednisone. Thus, if phenytoin is being taken, an increased dose of prednisone may be required.
- The risk of hypokalemia (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 (Coumadin, Jantoven). Therefore, warfarin therapy should be monitored closely.
- The response to diabetes drugs may be reduced because prednisone increases blood glucose.
- Prednisone may increase the risk of tendon rupture in patients treated with fluoroquinolone type antibiotics. Examples of fluoroquinolones include ciprofloxacin (Cipro) and levofloxacin (Levaquin).
- The elderly are especially at risk and tendon rupture may occur during or after treatment with fluoroquinolones.
- Combining aspirin, ibuprofen (Motrin) or other nonsteroidal anti-inflammatory agents (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 prednisone may reduce blood levels of prednisone. Conversely, ketoconazole, itraconazole (Sporanox), ritonavir (Norvir), indinavir (Crixivan), macrolide antibiotics such as erythromycin, and other drugs that reduce the activity of liver enzymes that breakdown prednisone may increase blood levels of prednisone.
- Rifampin decreases blood levels of prednisolone by increasing its breakdown in the liver. The dose of prednisolone may need to be increased in order to avoid therapeutic failure.
- Corticosteroids have variable effects of warfarin (Coumadin) therapy. Coagulation levels should be monitored more closely when anticoagulants are combined with corticosteroids.
- Estrogens may increase the levels of prednisolone by decreasing its breakdown. When estrogens are used with prednisolone, side effects of prednisolone should be monitored.
- Steroids increase blood sugar (glucose) levels and, therefore, reduce the effect of drugs used for treating diabetes.
- Activity of cyclosporine and corticosteroids increase when both drugs are combined. Seizures have been reported.
- Combining aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids increases the risk of gastrointestinal side effects.
- Combining corticosteroids with potassium-depleting agents (for example, diuretics) increases the risk of low blood potassium (hypokalemia). Vaccines are less effective in patients on prolonged corticosteroid treatment because corticosteroids suppress the immune system. Corticosteroids may also allow organisms contained in live attenuated vaccines to replicate.
Are prednisone and prednisolone safe to take while pregnant or breastfeeding?
- Corticosteroids cross the placenta into the fetus. Compared to other corticosteroids, however, prednisone 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. Prednisone is less likely than other corticosteroids to be secreted in breast milk, but it may still pose a risk to the infant.

AllergyAn allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.

Are Skin Rashes ContagiousDirect and indirect contact can spread some types of rashes from person to person. Rash treatment depends upon a rash's underlying cause. A rash that sheds large amounts of skin warrants urgent medical attention. Rashes can be either contagious or noncontagious. Noncontagious rashes include seborrheic dermatitis, atopic dermatitis, contact dermatitis, stasis dermatitis, psoriasis, nummular eczema, drug eruptions, hives, heat rash (miliaria), and diaper rash. Rashes usually considered contagious include molluscum contagiosum (viral), impetigo (bacterial), herpes (herpes simplex, types 1 and 2 viruses), rash caused by Neisseria meningitides (N. meningitides) (bacterial), rash and blisters that accompany shingles (herpes zoster virus), ringworm (fungal) infections (tinea), scabies (itch mite), chickenpox (viral), measles and rubella (viral), erythema infectiosum (viral), pityriasis rosea (viral), cellulitis and erysipelas (bacterial), lymphangitis (bacterial, and folliculitis (bacterial).
ArthritisArthritis 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.
Asthma OverviewAsthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.
Take the Asthma QuizAsthma is a chronic disease of the airways of the lungs, which can be managed with proper treatment. Triggered by two main causes, asthma symptoms can be brought on by environmental factors and surprising allergens.
Bronchitis is inflammation of the airways in the lung. Acute bronchitis is is short in duration (10 to 20 days) in comparison with chronic bronchitis, which lasts for months to years. Causes of acute bronchitis include viruses and bacteria, which means it can be contagious. Acute bronchitis caused by environmental factors such as pollution or cigarette smoke is not contagious. Common symptoms for acute bronchitis include nasal congestion, cough, headache, sore throat, muscle aches, and fatigue.
Acute bronchitis in children also my include runny nose, fever, and chest pain. Treatment for acute bronchitis are OTC pain relievers, cough suppressants (although not recommended in children), and rest. Infrequently antibiotics may be prescribed to treat acute bronchitis.
Chronic bronchitis is a cough that occurs daily with production of sputum that lasts for at least three months, two years in a row. Causes of chronic bronchitis include cigarette smoking, inhaled irritants, and underlying disease processes (such as asthma, or congestive heart failure). Symptoms include cough, shortness of breath, and wheezing. Treatments include bronchodilators and steroids. Complications of chronic bronchitis include COPD and emphysema.
Inner Ear Infection
An inner ear infection or otitis interna is caused by viruses or bacteria and can occur in both adults and children. An inner ear infection can cause symptoms and signs, for example, a severe ear, dizziness, vertigo, nausea and vomiting, and vertigo. An inner ear infection also may cause inflammation of the inner ear or labyrinthitis. Inner ear infections are not contagious; however, the bacteria and viruses that cause the infection can be transmitted to other people. Good hygiene practices will help decrease the chances of the infection spreading to others.
Inner ear infection symptoms and signs like ear pain and nausea may be relieved with home remedies or over the counter (OTC) medication. Some inner ear infections will need to be treated and cured with antibiotics or prescription pain or antinausea medication.
Labyrinthitis (Inner Ear Inflammation)
Labyrinthitis is inflammation of the labyrinth (the part of the ear responsible for balance and hearing). Doctors do not know the exact cause of labyrinthitis; however, they often are associated viral infections of the inner ear. Symptoms of labyrinthitis are ear pain or earache, ear discharge, problems with balance and walking, ringing in the ears, dizziness, nausea, vomiting, and vertigo. Viral infections associated with labyrinthitis are contagious.
Home remedies may help labyrinthitis symptoms and signs. Over-the-counter (OTC) and prescription medication may treat inner ear infections, labyrinthitis symptoms like vertigo and nausea, and help ear pain.
Osteoarthritis SlideshowOsteoarthritis (OA) is a degenerative joint disease affecting both cartilage and bone. Joints most often affected by osteoarthritis include the knees, hands, back, or hips. Osteoarthritis symptoms include pain, swelling and joint inflammation.
RashThe word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.

West Syndrome is rare condition that affects infants and children, and has three distinct signs and symptoms (characteristics), 1) abnormal brain waves on EEG, 2) infantile spasms (jackknife seizures), and 3) mental retardation. West syndrome characteristics appear between age 3 and 12 months. West syndrome is caused or associated with severe brain damage at birth, tuberosis sclerosis, and prenatal, perinatal, and postnatal disorders. Cryptogenic West syndrome has no identifiable cause).
There is no treatment or cure for West syndrome. Symptoms and signs of West syndrome may be managed with medication. The prognosis and life expectancy for an individual with West syndrome varies depending upon the cause and severity of signs and symptoms. For every 100 infants and children, about five will not live past age five.
