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 .
Inform your physician of all the medications you take (prescription and over the counter) and other medical conditions you have before taking a Medrol Dose Pack. If you are scheduled for surgery, the medical staff must be aware that you are on a Medrol Dose Pack. It never should be taken if you are allergic to methylprednisolone or have a fungal infection. Since steroids can weaken the immune system, avoid people who have colds and the flu. Contact your physician if you become exposed to the measles or chicken pox, as these illnesses can become serious when a person is on steroid medication.
