Medrol methylprednisolone 4 mg Tablet, 21-count — NDC 0009-0056-04 (Billing 00009-0056-04)

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 corti… [Excerpted — this section continues on DailyMed.]

ADVERSE REACTIONS Fluid and Electrolyte Disturbances • Sodium retention • Congestive heart failure in susceptible patients • Hypertension • Fluid retention • Potassium loss • Hypokalemic alkalosis Musculoskeletal • Muscle weakness • Loss of muscle mass • Steroid myopathy • Osteoporosis • Tendon rupture, particularly of the Achilles tendon • Vertebral compression fractures • Aseptic necrosis of femoral and humeral heads • Pathologic fracture of long bones Gastrointestinal • Peptic ulcer with possible perforation and hemorrhage • Pancreatitis • Abdominal distention • Ulcerative esophagitis Increases in alanine transaminase (ALT, SGPT), aspartate transaminase (AST, SGOT), and alkaline phosphatase have been observed following corticosteroid treatment.

These changes are usually small, not associated with any clinical syndrome and are reversible upon discontinuation. Dermatologic • Impaired wound healing • Petechiae and ecchymoses • May suppress reactions to skin tests • Thin fragile skin • Facial erythema • Increased sweating Neurological • Increased intracranial pressure with papilledema (pseudo-tumor cerebri) usually after treatment • Convulsions • Vertigo • Headache Endocrine • Development of Cushingoid state • Suppression of growth in children • Secondary adrenocortical and pituitary unresponsiveness, particularly in times of stress, as in trauma, surgery or illness • Menstrual irregularities • Decreased carbohydrate tolerance • Manifestations of latent diabetes mellitus • Increased requirements of insulin or oral hypoglycemic agents in diabetics Ophthalmic • Posterior subcapsular cataracts • Increased intraocular pressure • Glaucoma • Exophthalmos Metabolic • Negative nitrogen balance due to protein catabolism Vascular • Flushing The following additional reactions have been reported following oral as well as parenteral therapy: Urticaria and other allergic, anaphylactic or hypersensitivity reactions.

DRUG INTERACTIONS The pharmacokinetic interactions listed below are potentially clinically important. Mutual inhibition of metabolism occurs with concurrent use of cyclosporin and methylprednisolone; therefore, it is possible that adverse events associated with the individual use of either drug may be more apt to occur. Convulsions have been reported with concurrent use of methylprednisolone and cyclosporin.

Drugs that induce hepatic enzymes such as phenobarbital, phenytoin and rifampin may increase the clearance of methylprednisolone and may require increases in methylprednisolone dose to achieve the desired response. Drugs such as troleandomycin and ketoconazole may inhibit the metabolism of methylprednisolone and thus decrease its clearance. Therefore, the dose of methylprednisolone should be titrated to avoid steroid toxicity.

Methylprednisolone may increase the clearance of chronic high dose aspirin. This could lead to decreased salicylate serum levels or increase the risk of salicylate toxicity when methylprednisolone is withdrawn. Aspirin should be used cautiously in conjunction with corticosteroids in patients suffering from hypoprothrombinemia.

The effect of methylprednisolone on oral anticoagulants is variable. There are reports of enhanced as well as diminished effects of anticoagulant when given concurrently with corticosteroids. Therefore, coagulation indices should be monitored to maintain the desired anticoagulant effect.

PRECAUTIONS General Precautions Drug-induced secondary adrenocortical insufficiency may be minimized by gradual reduction of dosage. This type of relative insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted. Since mineralocorticoid secretion may be impaired, salt and/or a mineralocorticoid should be administered concurrently.

There is an enhanced effect of corticosteroids on patients with hypothyroidism and in those with cirrhosis. Corticosteroids should be used cautiously in patients with ocular herpes simplex because of possible corneal perforation. The lowest possible dose of corticosteroid should be used to control the condition under treatment, and when reduction in dosage is possible, the reduction should be gradual.

Psychic derangements may appear when corticosteroids are used, ranging from euphoria, insomnia, mood swings, personality changes, and severe depression, to frank psychotic manifestations. Also, existing emotional instability or psychotic tendencies may be aggravated by corticosteroids. Caution is required in patients with systemic sclerosis because an increased incidence of scleroderma renal crisis has been observed with corticosteroids, including methylprednisolone.

Steroids should be used with caution in nonspecific ulcerative colitis, if there is a probability of impending perforation, abscess or other pyogenic infection; diverticulitis; fresh intestinal anastomoses; active or latent peptic ulcer; renal insufficiency; hypertension; osteoporosis; and myasthenia gravis. Growth and development of infants and children on prolonged corticosteroid therapy should be carefully observed. Although controlled clinical trials have shown corticosteroids to be effective in speeding the resolution of acute exacerbations of multiple sclerosis, they do not show that corticosteroids affect the ultimate outcome or natural history of the disease.

The studies do show that relatively high doses of corticosteroids are necessary to demonstrate a significant effect. (See DOSAGE AND ADMINISTRATION .) Since complications of treatment with glucocorticoids are dependent on the size of the dose and the duration of treatment, a risk/benefit decision must be made in each individual case as to dose and duration of treatment and as to whether daily or intermittent therapy should be used. In post marketing experience, tumor lysis syndrome (TLS) has been reported in patients with malignancies, including hematological malignancies and solid tumors, following the use of systemic corticosteroids alone or in combination with other chemotherapeutic agents.

Patients at high risk of TLS, such as patients with tumors that have a high proliferative rate, high tumor burden and high sensitivity to cytotoxic agents, should be monitored closely and appropriate precautions should be taken.
