Warnings
In patients on corticosteroid therapy subjected to unusual stress, increased dosage of rapidly acting corticosteroids before, during, and after the stressful situation is indicated. Immunosuppression and Increased Risk of Infection Corticosteroids, including MEDROL, suppress the immune system and increase the risk of infection with any pathogen, including viral, bacterial, fungal, protozoan, or helminthic pathogens. Corticosteroids can:
Reduce resistance to new infections
Exacerbate existing infections
Increase the risk of disseminated infections
Increase the risk of reactivation or exacerbation of latent infections
Mask some signs of infection Corticosteroid-associated infections can be mild but can be severe and at times fatal. The rate of infectious complications increases with increasing corticosteroid dosages. Monitor for the development of infection and consider MEDROL withdrawal or dosage reduction as needed. Tuberculosis If MEDROL is used to treat a condition in patients with latent tuberculosis or tuberculin reactivity, reactivation of tuberculosis may occur. Closely monitor such patients for reactivation. During prolonged MEDROL therapy, patients with latent tuberculosis or tuberculin reactivity should receive chemoprophylaxis. Varicella Zoster and Measles Viral Infections Varicella and measles can have a serious or even fatal course in non-immune patients taking corticosteroids, including MEDROL. In corticosteroid-treated patients who have not had these diseases or are non-immune, particular care should be taken to avoid exposure to varicella and measles:
If a MEDROL-treated patient is exposed to varicella, prophylaxis with varicella zoster immune globulin may be indicated. If varicella develops, treatment with antiviral agents may be considered.
If a MEDROL-treated patient is exposed to measles, prophylaxis with immunoglobulin may be indicated. Hepatitis B Virus Reactivation Hepatitis B virus reactivation can occur in patients who are hepatitis B carriers treated with immunosuppressive dosages of corticosteroids, including MEDROL. Reactivation can also occur infrequently in corticosteroid-treated patients who appear to have resolved hepatitis B infection. Screen patients for hepatitis B infection before initiating immunosuppressive (e.g., prolonged) treatment with MEDROL. For patients who show evidence of hepatitis B infection, recommend consultation with physicians with expertise in managing hepatitis B regarding monitoring and consideration for hepatitis B antiviral therapy. Fungal Infections Corticosteroids, including MEDROL, may exacerbate systemic fungal infections; therefore, avoid MEDROL use in the presence of such infections unless MEDROL is needed to control drug reactions. For patients on chronic MEDROL therapy who develop systemic fungal infections, MEDROL withdrawal or dosage reduction is recommended. Amebiasis Corticosteroids, including MEDROL, may activate latent amebiasis. Therefore, it is recommended that latent amebiasis or active amebiasis be ruled out before initiating MEDROL in patients who have spent time in the tropics or patients with unexplained diarrhea. Strongyloides Infestation Corticosteroids, including MEDROL, 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. Cerebral Malaria Avoid corticosteroids, including MEDROL, in patients with cerebral malaria. Ophthalmic Effects 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. Kaposi’s Sarcoma 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 of Kaposi’s sarcoma. Hypertension, Volume Overload, and Hypokalemia 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. Vaccination 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. 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 child-bearing 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.
