In patients on corticosteroid therapy subjected to unusual stress, increased
dosage of rapidly acting corticosteroids before, during, and after the stressful
situation is indicated.
Corticosteroids may mask some signs of infection, and new infections may appear
during their use. Infections with any pathogen including viral, bacterial, fungal,
protozoan or helminthic infections, in any location of the body, may be associated
with the use of corticosteroids alone or in combination With other immunosuppressive
agents that affect cellular immunity, humoral immunity, or neutrophil function.1
These infections may be mild, but can be severe and at times fatal. With increasing
doses of corticosteroids, the rate of occurrence of infectious complications
increases.2 There may be decreased resistance and inability to localize
infection when corticosteroids are used. Prolonged use of corticosteroids may
produce posterior subcapsular cataracts, glaucoma with possible damage to the
optic nerves, and may enhance the establishment of secondary ocular infections
due to fungi or viruses.
Usage in pregnancy: Since adequate human reproduction studies have not
been done with corticosteroids, the use of these drugs in pregnancy, nursing
mothers or women of childbearing potential requires that the possible benefits
of the drug be weighed against the potential hazards to the mother and embryo
or fetus. Infants born of mothers who have received substantial doses of corticosteroids
during pregnancy, should be carefully observed for signs of hypoadrenalism.
Average and large doses of hydrocortisone or cortisone can cause elevation
of blood pressure, salt and water retention, and increased excretion of potassium.
These effects are less likely to occur with the synthetic derivatives except
when used in, large doses. Dietary salt restriction and potassium supplementation
may be necessary. All corticosteroids Increase calcium excretion.
Administration of live or live, attenuated vaccines is contraindicated in patients
receiving immunosuppressive doses of corticosteroids. Killed or inactivated
vaccines may be administered to patients receiving immunosuppressive doses of
corticosteroids; however, the response to such vaccines may be diminished. Indicated
immunization procedures may be undertaken in patients receiving nonimmunosuppressive
doses of corticosteroids.
The use of DELTASONE (prednisone) Tablets in active tuberculosis should be restricted to
those cases of fulminating or disseminated tuberculosis in which the corticosteroid
is used for the management of the disease in conjunction with an appropriate
anti-tuberculous regimen.
If corticosteroids are indicated in patients with latent tuberculosis or tuberculin
reactivity, close observation is necessary as reactivation of the disease may
occur. During prolonged corticosteroid therapy, these patients should receive
chemoprophylaxis.
Persons who are on drugs which suppress the immune system are more susceptible
to infections than healthy individuals. Chicken pox and measles, for example,
can have a more serious or even fatal course in non-immune children or adults
on corticosteroids. In such children or adults who have not had these diseases,
particular care should be taken to avoid exposure. How the dose, route and duration
of corticosteroid administration affects the risk of developing a disseminated
infection is not known. The contribution of the underlying disease and/or prior
corticosteroid treatment to the risk is also not known. If exposed to chicken
pox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated.
If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin
(IG) may be indicated. (See the respective package inserts for complete VZIG
and IG prescribing information.) If chicken pox develops, treatment with antiviral
agents may be considered. Similarly, corticosteroids. should be used with great
care in patients with known or suspected Strongyloides (threadworm) infestation.
In such patients, corticosteroid-induced immunosuppression may lead to Strongyloides
hyperinfection and dissemination with widespread larval migration, often accompanied
by severe enterocolitis and potentially fatal gram-negative septicemia.
