Posology and method of administration

The initial dosage may vary from 5mg to 60mg daily depending on the disorder being
treated. Divided daily dosage is usually used.
The following therapeutic guidelines should be kept in mind for all therapy with
Corticosteroids are palliative symptomatic treatment by virtue of their antiinflammatory effects; they are never curative.
The appropriate individual dose must be determined by trial and error and must be reevaluated regularly according to activity of the disease.
As corticosteroid therapy becomes prolonged and as the dose is increased, the
incidence of disabling side-effects increases.
In general, initial dosage shall be maintained or adjusted until the anticipated
response is observed. The dose should be gradually reduced until the lowest dose
which will maintain an adequate clinical response is reached. Use of the lowest
effective dose may also minimise side-effects (see 'Special warnings and special
precautions for use').
In patients who have received more than physiological dose for 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 hypothalamic-pituitary-adrenal (HPA)
suppression, the dose of 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 (or equivalent).
• patients repeatedly taking doses in the evening.
(See 'Special warnings and special precautions for use' and 'Undesirable effects')
During prolonged therapy, dosage may need to be temporarily increased during
periods of stress or during exacerbations of the disease (see 'Special warnings and
special precautions for use')

If there is lack of a satisfactory clinical response, the drug should be gradually
discontinued and the patient transferred to alternative therapy.
Intermittent dosage regimen: A single dose in the morning 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 corticosteroidresponsive 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
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.
Use in children: Although appropriate fractions of the actual dose may be used,
dosage will usually be determined by clinical response as in adults (see also 'Special
warnings and special precautions for use'). Alternate day dosage is preferable where
Use in elderly: Treatment of elderly patients, particularly if long-term, should be
planned bearing in mind the more serious consequences of the common side-effects
of corticosteroids in old age (see also 'Special warnings and special precautions for


Systemic infections unless specific anti-infective therapy is employed.
Hypersensitivity to any ingredient. Ocular herpes simplex because of possible


Special warnings and precautions for use
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.
Caution is necessary when oral corticosteroids, including prednisolone, are prescribed
in patients with the following conditions, and frequent patient monitoring is
• Tuberculosis: Those with a previous history of, or X-ray changes characteristic
of, tuberculosis. The emergence of active tuberculosis can, however, be prevented
by the prophylactic use of anti-tuberculosis therapy.
• Hypertension.
• Congestive heart failure.
• Liver failure.
• Renal insufficiency.
• Diabetes mellitus or in those with a family history of diabetes.
• 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 steroid-induced psychoses.
• Also, existing emotional instability or psychotic tendencies may be aggravated by
corticosteroids including prednisolone.
• Epilepsy, and/or seizure disorders
• Peptic ulceration.
• Previous steroid myopathy.
• Glucocorticoids should be used cautiously in patients with myasthenia gravis
receiving anticholinesterase therapy.
• Because cortisone has been reported rarely to increase blood coagulability and to
precipitate intravascular thrombosis, thromboembolism, and thrombophlebitis,
corticosteroids should be used with caution in patients with thromboembolic
• Duchenne’s muscular dystrophy: transient rhabdomyolysis and myoglobinuria
may occur following strenuous physical activity. It is not known whether this is
due to prednisolone itself or the increased physical activity.
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
on alternate days. Frequent patient review is required to titrate the dose appropriately
against disease activity (see 'Posology and method of administration').
Adrenocortical Insufficiency: Pharmacologic doses of corticosteroids administered
for prolonged periods may result in hypothalamic-pituitary-adrenal (HPA)
suppression (secondary adrenocortical insufficiency). The degree and duration of
adrenocortical insufficiency produced is variable among patients and depends on the
dose, frequency, time of administration, and duration of glucocorticoid therapy.
In addition, acute adrenal insufficiency leading to a fatal outcome may occur if
glucocorticoids are withdrawn abruptly. Drug-induced secondary adrenocortical

insufficiency may therefore be minimized by gradual reduction of dosage. This type
of relative insufficiency may persist for months after discontinuation of therapy;
therefore, in any situation of stress occurring during that period, hormone therapy
should be reinstituted. Since mineralocorticoid secretion may be impaired, salt and/or
a mineralocorticoid should be administered concurrently. 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 re-introduced.
Patients should carry “Steroid treatment” cards which give clear guidance on the
precautions to be taken to minimise risk and which provide details of prescriber, drug,
dosage and the duration of treatment.
Anti-inflammatory/Immunosuppressive effects and Infection: 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
infection such as septicaemia and tuberculosis may be masked and may reach an
advanced stage before being recognised when corticosteroids including prednisolone
are used. The immunosuppressive effects of glucocorticoids may result in activation
of latent infection or exacerbation of intercurrent infections.
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 specialist care and urgent treatment. Corticosteroids should not be stopped
and the dose may need to be increased. The effect of corticosteroids may be enhanced
in patients with hypothyroidism and in those with chronic liver disease with impaired
hepatic function.
Measles: Patients should be advised to take particular care to avoid exposure to
measles, and to seek immediate medical advice if exposure occurs. Prophylaxis with
intramuscular normal immunoglobulin may be needed.
Administration of Live Vaccines: Live vaccines should not be given to individuals on
high doses of corticosteroids, due to impaired immune response. Live vaccines should
be postponed until at least 3 months after stopping corticosteroid therapy. (See also
section 4.5 Interactions).
Ocular Effects: Prolonged use of corticosteroids may produce posterior subcapsular
cataracts and nuclear cataracts (particularly in children), exophthalmos, or increased
intraocular pressure, which may result in glaucoma with possible damage to the optic
nerves. Establishment of secondary fungal and viral infections of the eye may also be
enhanced in patients receiving glucocorticoids.
Corticosteroids should be used cautiously in patients with ocular herpes simplex
because of possible perforation.
Visual disturbance
Visual disturbance may be reported with systemic and topical corticosteroid use. If a
patient presents with symptoms such as blurred vison 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.
Cushing's disease: Because glucocorticoids can produce or aggravate Cushing's
syndrome, glucocorticoids should be avoided in patients with Cushing's disease
There is an enhanced effect of corticosteroids in patients with hypothyroidism and in
those with cirrhosis.
Psychic derangements may appear when corticosteroids, including prednisolone, are
used, ranging from euphoria, insomnia, mood swings, personality changes, and severe
depression, to frank psychotic manifestations.
Use in children: Corticosteroids cause growth retardation in infancy, childhood and
adolescence, which may be irreversible, and therefore long-term administration of
pharmacological doses should be avoided. If prolonged therapy is necessary,
treatment should be limited to the minimum suppression of the hypothalamo-pituitary
adrenal axis and growth retardation. The growth and development of infants and
children should be closely monitored. Treatment should be administered where
possible as a single dose on alternate days
Use in the elderly: Treatment of elderly patients, particularly if long term, should be
planned bearing in mind the more serious consequences of the common side-effects
of corticosteroids in old age, especially osteoporosis, diabetes, hypertension,
hypokalaemia, susceptibility to infection and thinning of the skin. Close clinical
supervision is required to avoid life threatening reactions.
Patients with rare hereditary problems of galactose intolerance, the Lapp lactase
deficiency or glucose-galactose malabsorption should not take this medicine.


Interaction with other medicinal products and other forms of interaction
Hepatic microsomal enzyme inducers: Drugs that induce hepatic enzyme
cytochrome P-450 (CYP) isoenzyme 3A4 such as phenobarbital, phenytoin,
rifampicin, rifabutin, carbamazepine, primidone and aminoglutethimide may reduce
the therapeutic efficacy of corticosteroids by increasing the rate of metabolism. Lack
of expected response may be observed and dosage may need to be increased.
Hepatic microsomal enzyme inhibitors: Drugs that inhibit hepatic enzyme
cytochrome P-450 (CYP) isoenzyme 3A4 (e.g. ketoconazole, troleandomycin) may
decrease glucocorticoid clearance. Dosages of glucocorticoids given in combination
with such drugs may need to be decreased to avoid potential adverse effects.
Antidiabetic agents: Glucocorticoids may increase blood glucose levels. Patients with
diabetes mellitus receiving concurrent insulin and/or oral hypoglycemic agents may
require dosage adjustments of such therapy.
CYP3A inhibitors: Co-treatment with CYP3A inhibitors, including cobicistatcontaining 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.
Non-steroidal anti-inflammatory drugs: Concomitant administration of ulcerogenic
drugs such as indomethacin during corticosteroid therapy may increase the risk of GI
ulceration. Aspirin should be used cautiously in conjunction with glucocorticoids in
patients with hypoprothrombinaemia. Although concomitant therapy with salicylate
and corticosteroids does not appear to increase the incidence or severity of GI
ulceration, the possibility of this effect should be considered.
Serum salicylate concentrations may decrease when corticosteroids are administered
concomitantly. The renal clearance of salicylates is increased by corticosteroids and
steroid withdrawal may result in salicylate intoxication. Salicylates and
corticosteroids should be used concurrently with caution. Patients receiving both
drugs should be observed closely for adverse effects of either drug.
Antibacterials: Rifamycins accelerate metabolism of corticosteroids and thus may
reduce their effect. Erythromycin inhibits metabolism of methylprednisolone and
possibly other corticosteroids.
Anticoagulants: Response to anticoagulants may be reduced or, less often, enhanced
by corticosteroids. Close monitoring of the INR or prothrombin time is required to
avoid spontaneous bleeding.
Antiepileptics Carbamazepine, phenobarbital, phenytoin, and primidone accelerate
metabolism of corticosteroids and may reduce their effect.
Antifungals: Risk of hypokalaemia may be increased with amphotericin, therefore
concomitant use with corticosteroids should be avoided unless corticosteroids are
required to control reactions; ketoconazole inhibits metabolism of
methylprednisolone and possibly other corticosteroids.
Antivirals: Ritonavir possibly increases plasma concentrations of prednisolone and
other corticosteroids.
Cardiac Glycosides: Increased toxicity if hypokalaemia occurs with corticosteroids.
Ciclosporin: Concomitant administration of prednisolone and ciclosporin may result
in decreased plasma clearance of prednisolone (i.e. increased plasma concentration of
prednisolone). The need for appropriate dosage adjustment should be considered
when these drugs are administered concomitantly.
Cytotoxics: Increased risk of haematological toxicity with methotrexate.
Mifepristone: Effect of corticosteroids may be reduced for 3-4 days after
Vaccines: Live vaccines should not be given to individuals with impaired immune
responsiveness. The antibody response to other vaccines may be diminished.
Oestrogens: Oestrogens may potentiate the effects of glucocorticoids and dosage
adjustments may be required if oestrogens are added to or withdrawn from a stable
dosage regimen.
Somatropin: Growth promoting effect may be inhibited.

Sympathomimetics: Increased risk of hypokalaemia if high doses of corticosteroids
given with high doses of bambuterol, fenoteral, formoteral, ritodrine, salbutamol,
salmeterol and terbutaline.
Other: The desired effects of hypoglycaemic agents (including insulin),
antihypertensives and diuretics are antagonised by corticosteroids; and the
hypokalaemic effect of acetazolamide, loop diuretics, thiazide diuretics,
carbenoxolone and theophylline are enhanced.


Fertility, Pregnancy and lactation
Use in pregnancy: 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 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 been observed in infants born
to mothers treated with long-term prednisolone during pregnancy. As with all drugs,
cortico-steroids 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.
Use in lactation: Corticosteroids are excreted in small amounts in breast milk.
Corticosteroids distributed into breast milk may suppress growth and interfere with
endogenous glucocorticoid production in nursing infants. Since adequate reproductive
studies have not been performed in humans with glucocorticoids, these drugs should
be administered to nursing mothers only if the benefits of therapy are judged to
outweigh the potential risks to the infant.


Effects on ability to drive and use machines
The effect on the ability to drive or use machinery has not been evaluated. There is no
evidence to suggest that prednisolone may affect these abilities.


Undesirable effects
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, 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.
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 'Special warnings and special
precautions for use').
Body as a Whole: Leucocytosis, hypersensitivity including anaphylaxis,
thromboembolism, fatigue, malaise.
Cardiovascular: congestive heart failure in susceptible patients, hypertension
Gastro-intestinal: Dyspepsia, nausea, peptic ulceration with perforation and
haemorrhage, abdominal distension, abdominal pain, increased appetite which may
result in weight gain, diarrhoea, oesophageal ulceration, oesophageal candidiasis,
acute pancreatitis.
Musculo-skeletal: Proximal myopathy, osteoporosis, vertebral and long bone
fractures, avascular osteonecrosis, tendon rupture, myalgia.
Metabolic/Nutritional: Sodium and water retention, hypokalaemic alkalosis,
potassium loss, negative nitrogen and calcium balance.
Skin/Appendages: Impaired healing, hirsutism, skin atrophy, bruising, striae,
telangiectasia, acne, increased sweating, may suppress reactions to skin tests, pruritis,
rash, urticaria.
Endocrine: Suppression of the hypothalamo-pituitary adrenal axis particularly in
times of stress, as in trauma, surgery or illness, growth suppression in infancy,
childhood and adolescence, menstrual irregularity and amenorrhoea. Cushingoid
facies, weight gain, impaired carbohydrate tolerance with increased requirement for
antidiabetic therapy, manifestation of latent diabetes mellitus, increased appetite.
Central and Peripheral Nervous System: Euphoria, psychological dependence,
depression, insomnia, dizziness, headache, vertigo. Raised intracranial pressure with
papilloedema (pseudotumor cerebri) in children, usually after treatment withdrawal.
Aggravation of schizophrenia. Aggravation of epilepsy.
Eye disorders: Increased intra-ocular pressure, glaucoma, papilloedema, posterior
subcapsular cataracts, exophthalmos, corneal or scleral thinning, exacerbation of
ophthalmic viral or fungal disease.
Rare: Vision, blurred (see also section 4.4)
Anti-inflammatory and immunosuppressive effects: Increases susceptibility to, and
severity of infections with suppression of clinical symptoms and signs, opportunistic
infections, recurrence of dormant tuberculosis (see 'Special warnings and special
precautions for use').
Withdrawal symptoms: Too rapid a reduction of corticosteroid dosage following
prolonged treatment can lead to acute adrenal insufficiency, hypotension and death
(see 'Special warnings and special precautions for use' and 'Posology and method of
administration'). A steroid “withdrawal syndrome” seemingly unrelated to
adrenocortical insufficiency may also occur following abrupt discontinuance of

glucocorticoids. This syndrome includes symptoms such as: anorexia, nausea,
vomiting, lethargy, headache, fever, joint pain, desquamation, myalgia, arthralgia,
rhinitis, conjunctivitis, painful itchy skin nodules weight loss, and/or hypotension.
These effects are thought to be due to the sudden change in glucocorticoid
concentration rather than to low corticosteroid levels.
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 at:


Reports of acute toxicity and/or death following overdosage of glucocorticoids are
rare. No specific antidote is available; treatment is supportive and symptomatic.
Serum electrolytes should be monitored.




Pharmacodynamic properties
Naturally occurring glucocorticoids (hydrocortisone and cortisone), which also have
salt-retaining properties, are used as replacement therapy in adreno-cortical
deficiency states. Their synthetic analogs are primarily used for their potent antiinflammatory effects in disorders of many organ systems.
Glucocorticoids cause profound and varied metabolic effects. In addition, they
modify the body’s immune responses to diverse stimuli.


Pharmacokinetic properties
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.


Preclinical safety data
There are no pre-clinical data of relevance to the prescriber which are additional to
that already included in other sections of the SPC.
