Documentation of allergenic cross-reactivity for corticosteroids is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Concerns related to adverse effects:
• Adrenal suppression: May cause hypercortisolism or suppression of hypothalamic-pituitary-adrenal (HPA) axis, particularly in younger children or in patients receiving high doses for prolonged periods. HPA axis suppression may lead to adrenal crisis. Withdrawal and discontinuation of a corticosteroid should be done slowly and carefully.
• Anaphylactoid reactions: Rare cases of anaphylactoid reactions have been observed in patients receiving corticosteroids.
• Immunosuppression: Prolonged use may increase risk of infection, mask acute infection (including fungal infections), prolong or exacerbate viral infections, or limit response to killed or inactivated vaccines. Exposure to chickenpox or measles should be avoided. Corticosteroids should not be used for cerebral malaria or viral hepatitis. Close observation is required in patients with latent tuberculosis (TB) and/or TB reactivity. Restrict use in active TB (only fulminating or disseminated TB in conjunction with antituberculosis treatment). Amebiasis should be ruled out in any patient with recent travel to tropic climates or unexplained diarrhea prior to initiation of corticosteroids. Use with extreme caution in patients with Strongyloides infections; hyperinfection, dissemination and fatalities have occurred.
• Kaposi sarcoma: Prolonged treatment with corticosteroids has been associated with the development of Kaposi sarcoma (case reports); if noted, discontinuation of therapy should be considered (Goedert 2002).
• Myopathy: Acute myopathy has been reported with high-dose corticosteroids, usually in patients with neuromuscular transmission disorders; may involve ocular and/or respiratory muscles; monitor creatine kinase; recovery may be delayed.
• Psychiatric disturbances: Corticosteroid use may cause psychiatric disturbances, including euphoria, insomnia, mood swings, personality changes, severe depression to psychotic manifestation. Preexisting psychiatric conditions may be exacerbated by corticosteroid use.
Disease-related concerns:
• Cardiovascular disease: Use with caution in patients with HF and/or hypertension; use may be associated with fluid retention, electrolyte disturbances, and hypertension. Use with caution following acute MI; corticosteroids have been associated with myocardial rupture.
• Diabetes: Use corticosteroids with caution in patients with diabetes mellitus; may alter glucose production/regulation leading to hyperglycemia.
• Gastrointestinal disease: Use with caution in patients with GI diseases (diverticulitis, fresh intestinal anastomoses, active or latent peptic ulcer, ulcerative colitis, abscess or other pyogenic infection) due to perforation risk.
• Hepatic impairment: Use with caution in patients with hepatic impairment, including cirrhosis; long-term use has been associated with fluid retention.
• Myasthenia gravis: Use may cause transient worsening of myasthenia gravis (MG) (eg, within first 2 weeks of treatment); monitor for worsening MG (AAN [Narayanaswami 2021]).
• Ocular disease: Use with caution in patients with cataracts and/or glaucoma; increased intraocular pressure, open-angle glaucoma, and cataracts have occurred with prolonged use. Use with caution in patients with a history of ocular herpes simplex; corneal perforation has occurred; do not use in active ocular herpes simplex. Consider routine eye exams in chronic users.
• Osteoporosis: Use with caution in patients with osteoporosis; high doses and/or long-term use of corticosteroids have been associated with increased bone loss and osteoporotic fractures.
• Renal impairment: Use with caution in patients with renal impairment; fluid retention may occur.
• Seizure disorders: Use corticosteroids with caution in patients with a history of seizure disorder; seizures have been reported with adrenal crisis.
• Systemic sclerosis: Use with caution in patients with systemic sclerosis; an increase in scleroderma renal crisis incidence has been observed with corticosteroid use. Monitor BP and renal function in patients with systemic sclerosis treated with corticosteroids (EULAR [Kowal-Bielecka 2017]).
• Thyroid disease: Changes in thyroid status may necessitate dosage adjustments; metabolic clearance of corticosteroids increases in hyperthyroid patients and decreases in hypothyroid ones.
Special populations:
• Elderly: Because of the risk of adverse effects, use with caution in the elderly with the smallest possible effective dose for the shortest duration.
• Pediatric: May affect growth velocity; growth and development should be routinely monitored in pediatric patients.
Other warnings/precautions:
• Discontinuation of therapy: Withdraw therapy with gradual tapering of dose.
• Stress: Patients may require higher doses when subject to stress (ie, trauma, surgery, severe illness).
May cause osteoporosis (at any age) or inhibition of bone growth in pediatric patients. Use with caution in patients with osteoporosis. In a population-based study of children, risk of fracture was shown to be increased with >4 courses of corticosteroids; underlying clinical condition may also impact bone health and osteoporotic effect of corticosteroids (Leonard 2007). Hypertrophic cardiomyopathy has been reported in premature neonates.

Animal reproduction studies have not been conducted with fludrocortisone; adverse events have been observed with corticosteroids in animal reproduction studies. Some studies have shown an association between first trimester systemic corticosteroid use and oral clefts (Park-Wyllie 2000; Pradat 2003). Systemic corticosteroids may also influence fetal growth (decreased birth weight); however, information is conflicting (Lunghi 2010). Hypoadrenalism may occur in newborns following maternal use of corticosteroids in pregnancy; monitor.
When systemic corticosteroids are needed in pregnancy, it is generally recommended to use the lowest effective dose for the shortest duration of time, avoiding high doses during the first trimester (Leachman 2006; Lunghi 2010). Fludrocortisone may be used to treat women during pregnancy who require therapy for congenital adrenal hyperplasia or primary adrenal insufficiency (Endocrine Society [Bornstein 2016; Speiser 2018]).
It is not known if fludrocortisone is excreted in breast milk; corticosteroids are excreted in breast milk. The manufacturer recommends that caution be exercised when administering fludrocortisone to nursing women.
Systemic use of mineralocorticoids/corticosteroids may require a diet with increased potassium, vitamins A, B6, C, D, folate, calcium, zinc, and phosphorus, and decreased sodium. With fludrocortisone, a decrease in dietary sodium is often not required as the increased retention of sodium is usually the desired therapeutic effect.
Blood pressure; blood glucose, electrolytes, weight; growth and development in children; HPA axis suppression.
Very potent mineralocorticoid with high glucocorticoid activity; used primarily for its mineralocorticoid effects. Promotes increased reabsorption of sodium and loss of potassium from renal distal tubules.
