The initial dosage of prednisolone may vary from 5-60mg daily depending on the disorder being treated. Preferably taken as a single dose in the morning, after breakfast. Divided daily dosage may be employed if required.
The following therapeutic guidelines should be kept in mind for all therapy with corticosteroids:
Corticosteroids are palliative symptomatic treatment by virtue of their anti-inflammatory effects; they are never curative.
The appropriate individual dose must be determined by trial and error and must be re-evaluated regularly according to activity of the disease. Please see “other undesirable effects section”.
As corticosteroid therapy becomes prolonged, and as the dose is increased, the incidence of disabling side-effects increases.
Abrupt cessation of prolonged high dosage corticosteroid therapy is associated with a significant risk of potentially life-threatening adrenal insufficiency. (See section 4.4 Special Warnings and Precautions or use).
In general, initial dosage should be maintained or adjusted until the anticipated response is observed. The dose should then be gradually reduced until the lowest dose which will maintain an adequate clinical response is reached.
During prolonged therapy, dosage may need to be temporarily increased during periods of stress or during exacerbations of the disease.
When the drug is to be stopped, it must be withdrawn gradually and not abruptly.
If there is a lack of clinical response to prednisolone, the drug should be gradually discontinued and the patient transferred to alternative therapy.
Intermittent dosage regimen: A single dose of prednisolone on alternate days or at longer intervals is acceptable therapy for some patients. When this regimen is practical, the degree of pituitary-adrenal suppression can be minimised.
Specific dosage guidelines: The following recommendations for some corticosteroid-responsive disorders are for guidance only. Acute or severe disease may require initial high dose therapy with reduction to the lowest effective maintenance dose as soon as possible. Dosage reductions should not exceed 5-7.5mg daily during chronic treatment.
• Allergic and skin disorders: Initial doses of 5-15mg daily are commonly adequate.
• Collagenosis: Initial doses of 20-30mg daily are frequently effective. Those with more severe symptoms may require higher doses.
• Rheumatoid arthritis: The usual initial dose is 10-15mg daily. The lowest daily maintenance dose compatible with tolerable symptomatic relief is recommended.
• Blood disorders and lymphoma: An initial daily dose of 15-60mg is often necessary with reduction after an adequate clinical or haematological response. Higher doses may be necessary to induce remission in acute leukaemia.
• Although appropriate fractions of the adult dose may be used, dosage will usually be determined by clinical response as in adults.
Aged 1-6 years- One quarter the adult dose.
Aged 7-11 years- One half the adult dose.
Aged 12-17 years- Three quarters the adult dose.
Corticosteroids cause growth retardation in infancy, childhood and adolescence which may be irreversible. Treatment should be limited to the minimum dosage for the shortest possible time. In order to minimise suppression of the hypothalamo-pituitary adrenal axis and growth retardation, treatment should be administered where possible as a single dose on alternate days.
• Elderly: Treatment of elderly patients, especially if long-term, should be planned bearing in mind the more serious consequences of the common side-effects of corticosteroids in old age, particularly diabetes, hypertension, hypokalaemia, osteoporosis, susceptibility to infection and thinning of the skin. Close clinical supervision is required to avoid life-threatening reactions.
Method of administration
For oral use.
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.
Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency, or glucose-galactose malabsorption should not take this medicine.
Systemic infections unless specific anti-infective therapy is employed.
Patients with ocular herpes simplex due to the possibility of perforation.
A patient information leaflet should be supplied with this product. Patients should carry “steroid treatment” cards which give clear guidance on the precautions to be taken to minimise risk and provide details of prescriber, drug, dosage and duration of treatment.
Patients/and or carers should be warned that potentially severe psychiatric adverse reactions may occur with systemic steroids (see section 4.8). Symptoms typically emerge within a few days or weeks of starting the treatment. Risks may be higher with high doses/systemic exposure (see also section 4.5 pharmacokinetic interactions that can increase the risk of side effects), although dose levels do not allow prediction of the onset, type, severity or duration of reactions. Most reactions recover after either dose reduction or withdrawal, although specific treatment may be necessary.
Patients/carers should be encouraged to seek medical advice if worrying psychological symptoms develop, especially if depressed mood or suicidal ideation is suspected. Patients/carers should also be alert to possible psychiatric disturbances that may occur either during or immediately after dose tapering/withdrawal of systemic steroids, although such reactions have been reported infrequently.
Particular care is required when considering the use of systemic corticosteroids in patients with existing or previous history of severe affective disorders in themselves or in their first degree relatives. These would include depressive or manic-depressive illness and previous steroid psychosis.
Visual disturbance may be reported with systemic and topical corticosteroid use. If a patient presents with symptoms such as blurred vision or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids.
Scleroderma renal crisis
Caution is required in patients with systemic sclerosis because of an increased incidence of (possibly fatal) scleroderma renal crisis with hypertension and decreased urinary output observed with a daily dose of 15 mg or more prednisolone. Blood pressure and renal function (s-creatinine) should therefore be routinely checked. When renal crisis is suspected, blood pressure should be carefully controlled.
Caution is necessary when corticosteroids, including prednisolone, are prescribed to patients with the following conditions and frequent patient monitoring is necessary:
• Diabetes mellitus or in those with a family history of diabetes.
• Glaucoma or in those with a family history of glaucoma.
• Hypertension or congestive heart failure.
• Liver failure.
• Osteoporosis: This is of special importance in post-menopausal females who are at particular risk.
• Patients with a history of severe affective disorders and particularly those with a previous history of corticosteroid induced psychoses.
• Peptic ulceration.
• Previous steroid myopathy.
• Renal insufficiency.
• Tuberculosis: Those with a history of, or X-ray changes characteristic of tuberculosis. The emergence of active tuberculosis can, however, be prevented by the prophylactic use of antituberculous therapy.
• Recent myocardial infarction (rupture).
• Chickenpox: Chickenpox is of particular concern since this normally minor illness may be fatal in immunosuppressed patients. Patients (or parents of children) without a definite history of chickenpox should be advised to avoid close personal contact with chickenpox or herpes zoster and if exposed they should seek urgent medical attention. Passive immunisation with varicella/zoster immunoglobulin (VZIG) is needed by exposed non-immune patients who are receiving systemic corticosteroids or who have used them within the previous 3 months; this should be given within 10 days of exposure to chickenpox. If a diagnosis of chickenpox is confirmed, the illness warrants special care and urgent treatment. Corticosteroids should not be stopped and the dose may need to be increased.
• Measles: Patients are advised to avoid exposure to measles, medical advice should be sought if exposure occurs. Propylaxis with intramuscular normal immunoglobulin may be needed.
• Suppression of the inflammatory response and immune function increases the susceptibility to infections and their severity. The clinical presentation may often be atypical and serious infections such as septicaemia and tuberculosis may be masked and may reach an advanced stage before being recognised.
• The effect of corticosteroids may be enhanced in patients with hypothyroidism in those with chronic liver disease with impaired hepatic function.
• Live vaccines should not be given to individuals with impaired immune responsiveness. The antibody response to other vaccines may be diminished.
• Adrenal cortical atrophy develops during prolonged therapy and may persist for years after stopping treatment.
• Patients with systemic sclerosis because of possible risk of scleroderma renal crisis which can be fatal.
In patients who have received more than physiological doses of systemic corticosteroids (approximately 7.5mg prednisolone or equivalent) for greater than 3 weeks, withdrawal should not be abrupt. How dose reduction should be carried out depends largely on whether the disease is likely to relapse as the dose of systemic corticosteroids is reduced. Clinical assessment of disease activity may be needed during withdrawal. If the disease is unlikely to relapse on withdrawal of systemic corticosteroids but there is uncertainty about HPA suppression, the dose of systemic corticosteroid may be reduced rapidly to physiological doses. Once a daily dose equivalent to 7.5mg of prednisolone is reached, dose reduction should be slower to allow the HPA-axis to recover.
Abrupt withdrawal of systemic corticosteroid treatment, which has continued up to 3 weeks is appropriate if it is considered that the disease is unlikely to relapse. Abrupt withdrawal of doses of up to 40mg daily of prednisolone, or equivalent for 3 weeks is unlikely to lead to clinically relevant HPA-axis suppression, in the majority of patients. In the following patient groups, gradual withdrawal of systemic corticosteroid therapy should be considered even after courses lasting 3 weeks or less:
• Patients who have had repeated courses of systemic corticosteroids, particularly if taken for greater than 3 weeks,
• When a short course has been prescribed within one year of cessation of long-term therapy (months or years),
• Patients who may have reasons for adrenocortical insufficiency other than exogenous corticosteroid therapy,
• Patients receiving doses of systemic corticosteroid greater than 40mg daily of prednisolone,
• Patients repeatedly taking doses in the evening.
During prolonged therapy any intercurrent illness, trauma or surgical procedure will require a temporary increase in dosage; if corticosteroids have been stopped following prolonged therapy they may need to be temporarily reintroduced.
• Antacids can reduce the absorbtion of prednisolone if given in high doses. Indigestion remedies should not be taken at the same time of day as Prednisolone.
• Rifampicin, rifabutin, carbamazepine, phenobarbital, phenytoin, primidone, carbimazole and aminoglutethimide enhance the metabolism of corticosteroids and its therapeutic effects may be reduced. Therefore it may be necessary to adjust the dose of prednisolone accordingly.
• The desired effects of hypoglycaemic agents (including insulin), antihypertensives and diuretics are antagonised by corticosteroids.
• The hypokalaemic effects of acetazolamide, loop diuretics, thiazide diuretics, beta-2-agonists, theophylline and carbenoxolone are enhanced.
• The efficacy of coumarin anticoagulants may be enhanced by concurrent corticosteroid therapy and close monitoring of the INR or prothrombin time is required to avoid spontaneous bleeding.
• Ciclosporin increases the plasma concentration of prednisolone.
• The renal clearance of salicylates is increased by corticosteroids and steroid withdrawal may result in salicylate intoxication.
• NSAIDs such as indometacin may increase the risk of GI ulceration. The possiblity of GI ulceration should be considered with concomitant use with any other NSAIDs.
• Antifungals: Increased risk of hypokalaemia with amphotericin. Avoid concomitant use. Ketoconazole reduces the metabolic and renal clearances of methylprednisolone, this may also occur with prednisolone.
• Mifepristone reduces the effect of corticosteroids for 3-4 days after administration.
• Methotrexate may have a steroid sparing effect. There is evidence that the toxicity of methotrexate is increased.
• Etoposide metabolism may be inhibited by corticosteroids in vitro. This may lead to an increase in both efficacy and toxicity of the etoposide. Monitoring would be prudent.
• Corticosteroids should not be used concurrently with retinoids and tetracyclines due to increased intracranial pressure.
• Oestrogens and progestogens increase plasma concentrations of corticosteroids.
• Co-treatment with CYP3A inhibitors, including cobicistat-containing products, is expected to increase the risk of systemic side-effects. The combination should be avoided unless the benefit outweighs the increased risk of systemic corticosteroid side-effects, in which case patients should be monitored for systemic corticosteroid side-effects.
The ability of corticosteroids to cross the placenta varies between individual drugs, however, 88% of prednisolone is inactivated as it crosses the placenta.
Administration of corticosteroids to pregnant animals can cause abnormalities of foetal development including cleft palate, intra-uterine growth retardation and effects on brain growth and development. There is no evidence that corticosteroids result in an increased incidence of congenital abnormalities, such as cleft palate/lip in man. However, when administered for prolonged periods or repeatedly during pregnancy, corticosteroids may increase the risk of intra-uterine growth retardation. Hypoadrenalism and immunosupression may, in theory, occur in the neonate following prenatal exposure to corticosteroids but usually resolves spontaneously following birth and is rarely clinically important. Cataracts have also been rarely reported.
As with all drugs, corticosteroids should only be prescribed when the benefits to the mother and child outweigh the risks. When corticosteroids are essential however, patients with normal pregnancies may be treated as though they were in the non-gravid state. Patients with pre-eclampsia or fluid retention require close monitoring.
Corticosteroids are excreted in small amounts in breast milk. However doses of up to 40mg daily of prednisolone are unlikely to cause systemic effects in the infant. Infants of mothers taking higher doses than this may have a degree of adrenal suppression but the benefits of breast feeding are likely to outweigh any theoretical risk. Monitoring of the infant for adrenal suppression is advised.
If insufficient sleep occurs, the likelihood of impaired alertness may be increased, patients should make sure they are not affected before driving or operating machinery.
The incidence of predictable undesirable effects, including hypothalamic-pituitary-adrenal suppression correlates with the relative potency of the drug, dosage, timing of administration and the duration of treatment (see “other special warnings and precautions”). Undesirable effects may be minimised by using the lowest effective dose for the minimum period, and by administering the daily requirement as a single morning dose or whenever possible as a single morning dose on alternative days. Frequent patient review is required to appropriately titrate the dose against disease activity.
Anti-inflammatory/immunosuppressive: Increased susceptibility and severity of infections with suppression of clinical symptoms and signs, opportunistic infections, recurrence of dormant tuberculosis. See “other special warnings and precautions”.
Gastrointestinal: Abdominal distension, acute pancreatitis, dyspepsia, nausea, increased appetite, oesophageal candidiasis, oesophageal ulceration, peptic ulceration with perforation and haemorrhage.
Endocrine/metabolic: Cushingoid facies, growth suppression in infancy, childhood and adolescence, hirsutism, impaired carbohydrate tolerance with increased requirement for antidiabetic therapy, menstrual irregularity and amenorrhoea, negative protein and calcium balance, suppression of the hypothalamo-pituitary adrenal axis, and weight gain. Although the frequency is not known, there is a risk for Cushing Syndrome.
Fluid and electrolyte disturbance: Hypertension, nocturia, hypokalaemic alkalosis, potassium loss, sodium and water retention.
Renal and urinary disorders: Scleroderma renal crisis* (frequency unknown)
Musculoskeletal: Avascular osteonecrosis, osteoporosis, proximal myopathy, tendon rupture, vertebral and long bone fractures.
Dermatological: Acne, bruising, impaired healing, skin atrophy, striae, telangiectasia.
Neuropsychiatric: A wide range of psychiatric reactions including affective disorders (such as irritable, euphoric, depressed and labile mood, and suicidal thoughts), psychotic reactions (including mania, delusions, hallucinations, and aggravation of schizophrenia), behavioural disturbances, irritability, nervousness, anxiety, sleep disturbances, and cognitive dysfunction including confusion and amnesia have been reported. Reactions are common and may occur in both adults and children. In adults, the frequency of severe reactions has been estimated to be 5-6%. Psychological effects have been reported on withdrawal of corticosteroids; the frequency is unknown.
Intracranial pressure with papilloedema in children (pseudotumour cerebri) usually after treatment withdrawal, psychological dependence.
Ophthalmic: Corneal or scleral thinning, exacerbation of ophthalmic viral or fungal disease, glaucoma, increased intra-ocular pressure, papilloedema, posterior subcapsular cataracts, central serous chorioretinopathy (frequency not known), vision, blurred (see also section 4.4) (frequency not known).
General: Hypersensitivity including anaphylaxis, leucocytosis, malaise, thromboembolism.
Withdrawal symptoms: Too rapid a reduction of corticosteroid dosage following prolonged treatment can lead to acute adrenal insufficiency, hypotension and death. See “other special warnings and precautions”. A “withdrawal syndrome” may also occur including arthralgia, conjunctivitis, fever, loss of weight, myalgia, painful itchy skin nodules and rhinitis.
* Scleroderma renal crisis
Amongst the different subpopulations the occurrence of scleroderma renal crisis varies. The highest risk has been reported in patients with diffuse systemic sclerosis. The lowest risk has been reported in patients with limited systemic sclerosis (2%) and juvenile onset systemic sclerosis (1%)
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme; website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
Reports of acute toxicity are rare. There is no specific antidote and treatment is supportive and symptomatic. Serum electrolytes should be monitored.
Pharmacotherapeutic group: Corticosteriods for systematic use, plain
ATC CODE: H02A B06
Mechanism of action
Prednisolone is one of the highly potent glucocorticoid steroids having anti-inflammatory, hormonal and metabolic effects qualitatively similar to those of hydrocortisone.
Glucocorticoids cause profound and varied metabolic effects. In addition, they modify the body's immune responses to diverse stimuli.
Prednisolone is rapidly and apparently almost completely absorbed after oral administration; it reaches peak plasma concentrations after 1-3 hours. There is however wide inter-subject variation suggesting impaired absorption in some individuals. Plasma half-life is about 3 hours in adults and somewhat less in children. Its initial absorption, but not its overall bioavailability, is affected by food. Prednisolone has a biological half-life lasting several hours, making it suitable for alternate-day administration regimens.
Although peak plasma prednisolone levels are somewhat lower after administration of Prednisolone Gastro-resistant Tablets and absorption is delayed, total absorption and bioavailability are the same as after plain prednisolone. Prednisolone shows dose dependent pharmacokinetics, with an increase in dose leading to an increase in volume of distribution and plasma clearance. The degree of plasma protein binding determines the distribution and clearance of free, pharmacologically active drug. Reduced doses are necessary in patients with hypoalbuminaemia.
Prednisolone is metabolised primarily in the liver to a biologically inactive compound. Liver disease prolongs the half-life of prednisolone and, if the patient has hypoalbuminaemia, also increases the proportion of unbound drug and may thereby increase adverse effects.
Prednisolone is excreted in the urine as free and conjugated metabolites, together with small amounts of unchanged prednisolone.
Significant differences in the pharmacokinetics of prednisolone amongst menopausal women have been described. The postmenopausal women had reduced unbound clearance (30%), reduced total clearance and increased half-life of prednisolone.
