Contraindications and Precautions for Dexamethasone Use

Introduction to Contraindications

• The Centers for Disease Control and Prevention recommends that dexamethasone is contraindicated in individuals with malignancies, including blood dyscrasias, leukemia, lymphomas, or other malignant neoplasias that affect the bone marrow or lymphatic systems 1
• The Centers for Disease Control and Prevention also recommends that dexamethasone is contraindicated in persons with primary or acquired immunodeficiency, including immunosuppression associated with HIV/AIDS or other clinical manifestations of HIV infection, cellular immunodeficiencies, hypogammaglobulinemia, and dysgammaglobulinemia 1

Contraindications Due to Medical Conditions

• Dexamethasone is contraindicated in patients with systemic fungal infections, as it may exacerbate these infections
• The use of dexamethasone in active tuberculosis should be restricted to cases of fulminant or disseminated tuberculosis where the corticosteroid is used in conjunction with an appropriate antitubercular regimen

Contraindications Due to Allergic Reactions and Vaccinations

• Dexamethasone is contraindicated in patients with a history of anaphylactic reactions to the drug or any of its components
• The administration of live virus vaccines is contraindicated in individuals receiving immunosuppressive doses of corticosteroids

Contraindications Due to Pregnancy, Lactation, and Administration Route

• Dexamethasone should not be administered to pregnant women due to unknown effects on the fetus
• Mothers taking pharmacologic doses of corticosteroids should be advised not to breastfeed, as these drugs appear in breast milk and may suppress growth or interfere with endogenous corticosteroid production in the infant
• Dexamethasone is not approved for epidural administration due to reports of serious neurological events, including spinal cord infarction, paraplegia, quadriplegia, cortical blindness, and stroke

Evaluation of Patients Before Dexamethasone Use

• Evaluate the presence of infections, including systemic fungal infections and tuberculosis
• Assess the patient's immunological status, including history of allergic reactions to corticosteroids and presence of immunodeficiencies
• Evaluate specific conditions, such as malignancies affecting the bone marrow or lymphatic system, pregnancy, or lactation
• Consider the route of administration and avoid epidural administration
