General
When multidose vials are used, special care to prevent
contamination of the contents is essential. A povidone-iodine solution or
similar product is recommended to cleanse the vial top prior to aspiration of
contents. (See WARNINGS)
This product, like many other steroid formulations, is
sensitive to heat. Therefore, it should not be autoclaved when it is desirable
to sterilize the outside 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 glucocorticosteroids
are dependent on the size of the dose and 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 mineral corticosteroid secretion may be impaired, salt
and/or a mineral corticosteroid 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 in caution in active or latent
peptic ulcer, diverticulitis, fresh intestinal anastomoses, and non-specific
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 increased metabolism of
corticosteroids in patients with cirrhosis.
Parenteral Administration
Intra-articular injected corticosteroids may be systemically
absorbed.
Appropriate examination of any joint fluid is necessary to
exclude a septic process.
A marked increase in pain associated by local swelling,
further restriction of joint motion, fever, malaise are suggestive of septic
arthritis. If this complication occurs and the diagnosis of sepsis is
confirmed, appropriate antimicrobial therapy should be instituted.
Injection of a steroid into an infected site is to be
avoided. Local injection of a steroid into a previously infected joint is not
usually recommended.
Musculoskeletal
Corticosteroids decrease bone formation and increase bone
resorption both through their effect on calcium regulation (e.g., decreasing
absorption and increasing excretion) and inhibition of osteoblast function.
This, together with a decrease in 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 (e.g., postmenopausal women) before initiating
corticosteroid therapy.
Neuro-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 results in quadriparesis. Elevation 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.
Corticosteroids should be used cautiously in patients with
ocular herpes simplex for fear of corneal perforation.
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 human dose. Animal studies in which
corticosteroids have been given to pregnant mice, rats, and rabbits, have
yielded an increase incidence of cleft palate in the off-spring. 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
This product contains benzyl alcohol as a preservative.
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 nephritic syndrome (patients > 2 years of age), and aggressive
lymphomas and leukemias (patients > 1 month of age). Other indications for
pediatric use of corticosteroids, e.g., severe asthma and wheezing, are based
on adequate and well-controlled clinical 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
hypothalamic-pituitary-adrenal (HPA) axis suppression (e.g., 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 ability 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.
