Depo - Medrol - Methylprednisolone Acetate injection, Suspension
(Methylprednisolone Acetate)Depo - Medrol - Methylprednisolone Acetate injection, Suspension Prescribing Information
When oral therapy is not feasible and the strength, dosage form, and route of administration of the drug reasonably lend the preparation to the treatment of the condition, the intramuscular use of DEPO-MEDROL Sterile Aqueous Suspension is indicated as follows:
The initial dosage of parenterally administered DEPO-MEDROL will vary from 4 to 120 mg, depending on the specific disease entity being treated. However, in certain overwhelming, acute, life-threatening situations, administration in dosages exceeding the usual dosages may be justified and may be in multiples of the oral dosages.
DEPO-MEDROL is contraindicated in patients with known hypersensitivity to the product and its constituents.
Intramuscular corticosteroid preparations are contraindicated for idiopathic thrombocytopenic purpura.
DEPO-MEDROL is contraindicated for intrathecal administration. This formulation of methylprednisolone acetate has been associated with reports of severe medical events when administered by this route.
DEPO-MEDROL is contraindicated in systemic fungal infections, except when administered as an intra-articular injection for localized joint conditions (see
Corticosteroids, including DEPO-MEDROL, may exacerbate systemic fungal infections; therefore, avoid DEPO-MEDROL use in the presence of such infections unless DEPO-MEDROL is needed to control drug reactions. For patients on chronic DEPO-MEDROL therapy who develop systemic fungal infections, DEPO-MEDROL withdrawal or dosage reduction is recommended.
The following adverse reactions have been reported with DEPO-MEDROL or other corticosteroids:
WARNINGSSerious Neurologic Adverse Reactions with Epidural AdministrationSerious neurologic events, some resulting in death, have been reported with epidural injection of corticosteroids. Specific events reported include, but are not limited to, spinal cord infarction, paraplegia, quadriplegia, cortical blindness, and stroke. These serious neurologic events have been reported with and without use of fluoroscopy. The safety and effectiveness of epidural administration of corticosteroids have not been established, and corticosteroids are not approved for this use.
GeneralRare instances of anaphylactoid reactions have occurred in patients receiving corticosteroid therapy (see
Increased dosage of rapidly acting corticosteroids is indicated in patients on corticosteroid therapy subjected to any unusual stress before, during, and after the stressful situation.
Results from one multicenter, randomized, placebo-controlled study with methylprednisolone hemisuccinate, an IV corticosteroid, showed an increase in early (at 2 weeks) and late (at 6 months) mortality in patients with cranial trauma who were determined not to have other clear indications for corticosteroid treatment. High doses of systemic corticosteroids, including DEPO-MEDROL, should not be used for the treatment of traumatic brain injury.
Cardio-renalAverage and large doses of corticosteroids can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium. These effects are less likely to occur with synthetic derivatives when used in large doses. Dietary salt restriction and potassium supplementation may be necessary. All corticosteroids increase calcium excretion.
Literature reports suggest an apparent association between use of corticosteroids and left ventricular free wall rupture after a recent myocardial infarction; therefore, therapy with corticosteroids should be used with great caution in these patients.
There have been cases reported in which concomitant use of amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure (see
EndocrineHypothalamic-pituitary adrenal (HPA) axis suppression. Cushing's syndrome, and Hyperglycemia: Monitor patients for these conditions with chronic use.
Corticosteroids can produce reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal of treatment. 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.
Immunosuppression and Increased Risk of InfectionCorticosteroids, including DEPO-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 DEPO-MEDROL withdrawal or dosage reduction as needed.
Do not administer DEPO-MEDROL by an intraarticular, intrabursal, intratendinous or intralesional route in the presence of acute local infection.
If DEPO-MEDROL is used to treat a condition in patients with latent tuberculosis or tuberculin reactivity, as reactivation of the disease may occur. Closely monitor such patients for reactivation. During prolonged DEPO-MEDROL therapy, patients with latent tuberculosis or tuberculin reactivity should receive chemoprophylaxis.
Varicella and measles can have a serious or even fatal course in non-immune patients taking corticosteroids, including DEPO-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 DEPO-MEDROL-treated patient is exposed to varicella, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If varicella develops, treatment with antiviral agents may be considered.• If a DEPO-MEDROL-treated patient is exposed to measles, prophylaxis with immunoglobulin (IG) may be indicated.
Hepatitis B virus reactivation can occur in patients who are hepatitis B carriers treated with immunosuppressive dosages of corticosteroids, including DEPO‑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 DEPO-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.
Corticosteroids, including DEPO-MEDROL, may exacerbate systemic fungal infections; therefore, avoid DEPO-MEDROL use in the presence of such infections unless DEPO-MEDROL is needed to control drug reactions. For patients on chronic DEPO-MEDROL therapy who develop systemic fungal infections, DEPO-MEDROL withdrawal or dosage reduction is recommended.
Corticosteroids, including DEPO-MEDROL, may activate latent amebiasis. Therefore, it is recommended that latent amebiasis or active amebiasis be ruled out before initiating DEPO-MEDROL in patients who have spent time in the tropics or patients with unexplained diarrhea.
Corticosteroids, including DEPO-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.
Avoid corticosteroids, including DEPO-MEDROL, in patients with cerebral malaria.
VaccinationsImmunization procedures may be undertaken in patients who are receiving corticosteroids as replacement therapy (e.g., for Addison’s disease).
OphthalmicUse 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 bacteria, fungi, or viruses. The use of systemic corticosteroids is not recommended in the treatment of optic neuritis and may lead to an increase in the risk of new episodes. Corticosteroids should be used cautiously in patients with ocular herpes simplex because of corneal perforation. Corticosteroids should not be used in active ocular herpes simplex.
Kaposi’s SarcomaKaposi’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.
WARNINGSSerious Neurologic Adverse Reactions with Epidural AdministrationSerious neurologic events, some resulting in death, have been reported with epidural injection of corticosteroids. Specific events reported include, but are not limited to, spinal cord infarction, paraplegia, quadriplegia, cortical blindness, and stroke.
