General
This product, like many other steroid formulations, is
sensitive to heat. Therefore, it should not be autoclaved when it is desirable
to sterilize the exterior of the vial.
The lowest possible dose of corticosteroid should be used to
control the condition under treatment. When reduction in dosage is possible,
the reduction should be gradual.
Since complications of treatment with glucocorticoids are
dependent on the size of the dose and the duration of treatment, a risk/benefit
decision must be made in each individual case as to dose and duration of
treatment and as to whether daily or intermittent therapy should be used.
Kaposi's sarcoma has been reported to occur in patients
receiving corticosteroid therapy, most often for chronic conditions.
Discontinuation of corticosteroids may result in clinical improvement.
Cardio-renal
As sodium retention with resultant edema and potassium loss
may occur in patients receiving corticosteroids, these agents should be used
with caution in patients with congestive heart failure, hypertension, or renal
insufficiency.
Endocrine
Drug-induced secondary adrenocortical insufficiency may 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.
Metabolic clearance of corticosteroids is decreased in
hypothyroid patients and increased in hyperthyroid patients. Changes in thyroid
status of the patient may necessitate adjustment in dosage.
Gastrointestinal
Steroids should be used with caution in active or latent
peptic ulcers, diverticulitis, fresh intestinal anastomoses, and nonspecific
ulcerative colitis, since they may increase the risk of a perforation. Signs of
peritoneal irritation following gastrointestinal perforation in patients
receiving corticosteroids may be minimal or absent.
There is an enhanced effect due to decreased metabolism of
corticosteroids in patients with cirrhosis.
Musculoskeletal
Corticosteroids decrease bone formation and increase bone
resorption both through their effect on calcium regulation (i.e., decreasing
absorption and increasing excretion) and inhibition of osteoblast function.
This, together with a decrease in the protein matrix of the bone secondary to
an increase in protein catabolism, and reduced sex hormone production, may lead
to inhibition of bone growth in pediatric patients and the development of
osteoporosis at any age. Special consideration should be given to patients at
increased risk of osteoporosis (i.e., postmenopausal women) before initiating
corticosteroid therapy.
Local injection of a steroid into a previously infected site
is not usually recommended.
Neurologic-psychiatric
Although controlled clinical trials have shown
corticosteroids to be effective in speeding the resolution of acute
exacerbations of multiple sclerosis, they do not show that corticosteroids
affect the ultimate outcome or natural history of the disease. The studies do
show that relatively high doses of corticosteroids are necessary to demonstrate
a significant effect. (See DOSAGE AND ADMINISTRATION.)
An acute myopathy has been observed with the use of high
doses of corticosteroids, most often occurring in patients with disorders of
neuromuscular transmission (e.g., myasthenia gravis), or in patients receiving
concomitant therapy with neuromuscular blocking drugs (e.g., pancuronium). This
acute myopathy is generalized, may involve ocular and respiratory muscles, and
may result in quadriparesis. Elevations of creatine kinase may occur. Clinical
improvement or recovery after stopping corticosteroids may require weeks to
years.
Psychic derangements may appear when corticosteroids are
used, ranging from euphoria, insomnia, mood swings, personality changes, and
severe depression, to frank psychotic manifestations. Also, existing emotional
instability or psychotic tendencies may be aggravated by corticosteroids.
Ophthalmic
Intraocular pressure may become elevated in some
individuals. If steroid therapy is continued for more than 6 weeks, intraocular
pressure should be monitored.
Carcinogenesis, Mutagenesis, Impairment of Fertility
No adequate studies have been conducted in animals to
determine whether corticosteroids have a potential for carcinogenesis or
mutagenesis.
Steroids may increase or decrease motility and number of
spermatozoa in some patients.
Pregnancy
Teratogenic effects: Pregnancy Category C.
Corticosteroids have been shown to be teratogenic in many
species when given in doses equivalent to the human dose. Animal studies in
which corticosteroids have been given to pregnant mice, rats, and rabbits have
yielded an increased incidence of cleft palate in the offspring. There are no
adequate and well-controlled studies in pregnant women. Corticosteroids should
be used during pregnancy only if the potential benefit justifies the potential
risk to the fetus. Infants born to mothers who have received corticosteroids
during pregnancy should be carefully observed for signs of hypoadrenalism.
Nursing Mothers
Systemically administered corticosteroids appear in human
milk and could suppress growth, interfere with endogenous corticosteroid
production, or cause other untoward effects. Because of the potential for
serious adverse reactions in nursing infants from corticosteroids, a decision
should be made whether to continue nursing, or discontinue the drug, taking
into account the importance of the drug to the mother.
Pediatric Use
Some formulations of this product contain benzyl alcohol as
a preservative (see DESCRIPTION). Carefully examine vials to determine
formulation that is being used.
Benzyl alcohol, a component of this product, has been
associated with serious adverse events and death, particularly in pediatric
patients. The “gasping syndrome” (characterized by central nervous system
depression, metabolic acidosis, gasping respirations, and high levels of benzyl
alcohol and its metabolites found in the blood and urine) has been associated
with benzyl alcohol dosages > 99 mg/kg/day in neonates and low-birth-weight
neonates. Additional symptoms may include gradual neurological deterioration,
seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown,
hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse.
Although normal therapeutic doses of this product deliver amounts of benzyl
alcohol that are substantially lower than those reported in association with
the “gasping syndrome”, the minimum amount of benzyl alcohol at which toxicity
may occur is not known. Premature and low-birth-weight infants, as well as
patients receiving high dosages, may be more likely to develop toxicity.
Practitioners administering this and other medications containing benzyl
alcohol should consider the combined daily metabolic load of benzyl alcohol
from all sources.
The efficacy and safety of corticosteroids in the pediatric
population are based on the well-established course of effect of
corticosteroids which is similar in pediatric and adult populations. Published
studies provide evidence of efficacy and safety in pediatric patients for the
treatment of nephrotic syndrome ( > 2 years of age), and aggressive lymphomas
and leukemias ( > 1 month of age). Other indications for pediatric use of
corticosteroids, e.g., severe asthma and wheezing, are based on adequate and
well-controlled trials conducted in adults, on the premises that the course of
the diseases and their pathophysiology are considered to be substantially
similar in both populations.
The adverse effects of corticosteroids in pediatric patients
are similar to those in adults (see ADVERSE REACTIONS). Like adults,
pediatric patients should be carefully observed with frequent measurements of
blood pressure, weight, height, intraocular pressure, and clinical evaluation
for the presence of infection, psychosocial disturbances, thromboembolism,
peptic ulcers, cataracts, and osteoporosis. Pediatric patients who are treated
with corticosteroids by any route, including systemically administered
corticosteroids, may experience a decrease in their growth velocity. This
negative impact of corticosteroids on growth has been observed at low systemic
doses and in the absence of laboratory evidence of HPA axis suppression (i.e.,
cosyntropin stimulation and basal cortisol plasma levels). Growth velocity may
therefore be a more sensitive indicator of systemic corticosteroid exposure in
pediatric patients than some commonly used tests of HPA axis function. The
linear growth of pediatric patients treated with corticosteroids should be
monitored, and the potential growth effects of prolonged treatment should be
weighed against clinical benefits obtained and the availability of treatment
alternatives. In order to minimize the potential growth effects of
corticosteroids, pediatric patients should be titrated to the lowest effective
dose.
Geriatric Use
Clinical studies did not include sufficient numbers of
subjects aged 65 and over to determine whether they respond differently from
younger subjects. Other reported clinical experience has not identified
differences in responses between the elderly and younger patients. In general,
dose selection for an elderly patient should be cautious, usually starting at
the low end of the dosing range, reflecting the greater frequency of decreased
hepatic, renal, or cardiac function, and of concomitant disease or other drug
therapy.
