Methylprednisolone, like other corticosteroids, can cause false negative test results i. Methylprednisolone may cause stomach ulcers to worsen or develop. People with stomach problems or a history of stomach problems, should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
A dosage adjustment of methylprednisolone may be required for anyone subjected to unusual stress. Methylprednisolone may not clear from the body at the expected rate when a person is hypothyroid. As a result, the effects of the medication may be increased.
People with hypothyroidism should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
People receiving immunosuppressive doses of corticosteroids should not receive live or live-attenuated modified vaccines, as there is a risk of infection and poor immune response to the vaccine. Endocrine Disorders Primary or secondary adrenocortical insufficiency hydrocortisone or cortisone is the drug of choice; synthetic analogs may be used in conjunction with mineralocorticoids where applicable; in infancy, mineralocorticoid supplementation is of particular importance , congenital adrenal hyperplasia, hypercalcemia associated with cancer, nonsuppurative thyroiditis.
Gastrointestinal Diseases To tide the patient over a critical period of the disease in regional enteritis systemic therapy and ulcerative colitis. Hematologic Disorders Acquired autoimmune hemolytic anemia, congenital erythroid hypoplastic anemia Diamond Blackfan anemia , pure red cell aplasia, select cases of secondary thrombocytopenia. Miscellaneous Trichinosis with neurologic or myocardial involvement, tuberculous meningitis with subarachnoid block or impending block when used concurrently with appropriate antituberculous chemotherapy.
Neoplastic Diseases For palliative management of leukemias and lymphomas. Nervous System Acute exacerbations of multiple sclerosis; cerebral edema associated with primary or metastatic brain tumor or craniotomy. Ophthalmic Diseases Sympathetic ophthalmia, temporal arteritis, uveitis and ocular inflammatory conditions unresponsive to topical corticosteroids.

Respiratory Diseases Berylliosis, fulminating or disseminated pulmonary tuberculosis when used concurrently with appropriate antituberculous chemotherapy, idiopathic eosinophilic pneumonias, symptomatic sarcoidosis.
Rheumatic Disorders As adjunctive therapy for short-term administration to tide the patient over an acute episode or exacerbation in acute gouty arthritis; acute rheumatic carditis; ankylosing spondylitis; psoriatic arthritis; rheumatoid arthritis, including juvenile rheumatoid arthritis selected cases may require low-dose maintenance therapy.
For the treatment of dermatomyositis, polymyositis, and systemic lupus erythematosus. Methylprednisolone acetate injectable suspension also may be useful in cystic tumors of an aponeurosis or tendon ganglia.
Contraindications Methylprednisolone acetate injectable suspension is contraindicated in patients with known hypersensitivity to the product and its constituents. Intramuscular corticosteroid preparations are contraindicated for idiopathic thrombocytopenic purpura. Methylprednisolone acetate injectable suspension is contraindicated for intrathecal administration.
Reports of severe medical events have been associated with this route of administration. Methylprednisolone acetate injectable suspension is contraindicated for use in premature infants because the formulation contains benzyl alcohol. Methylprednisolone acetate injectable suspension is contraindicated in systemic fungal infections, except when administered as an intra-articular injection for localized joint conditions see WARNINGS, Infections, Fungal Infections.
Warnings Serious Neurologic Adverse Reactions with Epidural Administration Serious 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.
General This product contains benzyl alcohol, which is potentially toxic when administered locally to neural tissue. Exposure to excessive amounts of benzyl alcohol has been associated with toxicity hypotension, metabolic acidosis , particularly in neonates, and an increased incidence of kernicterus, particularly in small preterm infants.
There have been rare reports of deaths, primarily in preterm infants, associated with exposure to excessive amounts of benzyl alcohol. The amount of benzyl alcohol in medications is usually considered negligible compared to that received in flush solutions containing benzyl alcohol. Administration of high dosages of medications containing this preservative must take into account the total amount of benzyl alcohol administered. The amount of benzyl alcohol at which toxicity may occur is not known.
Multidose use of methylprednisolone acetate injectable suspension from a single vial requires special care to avoid contamination.
Although initially sterile, any multidose use of vials may lead to contamination unless strict aseptic technique is observed.
Particular care, such as use of disposable sterile syringes and needles, is necessary. In order to minimize the incidence of dermal and subdermal atrophy, care must be exercised not to exceed recommended doses in injections. Multiple small injections into the area of the lesion should be made whenever possible. The technique of intra-articular and intramuscular injection should include precautions against injection or leakage into the dermis.
Injection into the deltoid muscle should be avoided because of a high incidence of subcutaneous atrophy.
Following intrasynovial injection, relief from pain may be experienced within 12 to 24 hours. The duration of relief varies, but averages three to four weeks, with a range of one to five or more weeks.
Injections of methylprednisolone acetate have been well tolerated. Intrasynovial intra-articular injections may occasionally result in an increased localized inflammatory response. Intrasynovial injection is recommended as an adjuvant to general therapeutic measures to effect suppression of inflammation in one or a few peripheral structures when 1 the disease is limited to one or a few peripheral structures; 2 the disease is widespread with one or a few peripheral structures actively inflamed; 3 systemic therapy with other corticoids or corticotropin controls all but a few of the more actively involved structures; 4 systemic therapy with cortisone, hydrocortisone, or corticotropin is contraindicated; 5 joints show early but actively progressing deformity to enhance the effect of physiotherapy and corrective procedures ; and 6 surgical or other orthopedic corrective measures are to be or have been done.
In a few instances mild and transient improvement of structures other than those injected have been reported. No other systemic effects have been noted. However, it is possible that mild systemic effects may occur following intrasynovial administration, and this possibility is greater the larger the number of structures injected and the higher the total dose employed. Procedure for Intrasynovial Injection. The anatomy of the area to be injected should be reviewed in order to assure that the suspension is properly placed and to determine that large blood vessels or nerves are avoided.
The injection site is located where the synovial cavity is most superficial. A sterile to gauge needle for horses, to gauge needle for dogs, on a dry syringe is quickly inserted into the synovial space and a small amount of synovial fluid withdrawn. It is possible that adverse events associated with the use of either drug alone may be more likely to occur with coadministration.
Convulsions have been reported with concurrent use of methylprednisolone and ciclosporin CYP3A4 inhibitor and substrate. Since concurrent administration of these agents results in a mutual inhibition of metabolism which may increase the plasma concentrations of either or both drugs , it is possible that convulsions and other adverse effects associated with the individual use of either drug may be more apt to occur.
Drugs that induce hepatic enzymes, such as rifampicin antibiotic CYP3A4 inducer , rifabutin, carbamazepine anticonvulsant CYP3A4 inducer and substrate , phenobarbitone and phenytoin anticonvulsants CYP3A4 inducers , primidone, and aminoglutethimide aromatase inhibitor enhance the metabolism of corticosteroids and its therapeutic effects may be reduced. Aminoglutethimide- induced adrenal suppression may exacerbate endocrine changes caused by prolonged glucocorticoid treatment.
The acetylation rate and clearance of isoniazid CYP3A4 inhibitor , an antibacterial drug, can be increased by methylprednisolone. Troleandomycin CYP3A4 inhibitor , as well as clarithromycin, erythromycin, itraconazole and ketoconazole CYP3A4 inhibitors and substrates increase the effects and the side effects of methylprednisolone. Steroids may reduce the effects of anticholinesterases in myasthenia gravis.
The desired effects of hypoglycaemic agents including insulin , anti-hypertensives and diuretics are antagonised by corticosteroids, and the hypokalaemic effects of acetazolamide, loop diuretics, thiazide diuretics and carbenoxolone are enhanced.
An acute myopathy has been reported with the concomitant use of high doses of corticosteroids and anticholinergics, such as neuromuscular blocking drugs.
Antagonism of the neuromuscular blocking effects of pancuronium and vecuronium has been reported in patients taking corticosteroids. This interaction may be expected with all competitive neuromuscular blockers. The effect of methylprednisolone on oral anticoagulants is variable. The efficacy of coumarin anticoagulants may be enhanced by concurrent corticosteroid therapy and close monitoring of the INR or prothrombin time is required to avoid spontaneous bleeding and to maintain the desired anticoagulant effects.
There are also reports of diminished effects of anticoagulants when given concurrently with corticosteroids. There may be increased incidence of gastrointestinal bleeding and ulceration when corticosteroids are given with NSAIDs. Methylprednisolone may increase the clearance of high-dose aspirin, which can lead to decreased salicylate serum levels.
Discontinuation of methylprednisolone treatment can lead to raised salicylate serum levels, which could lead to an increased risk of salicylate toxicity. Salicylates and non-steroidal anti-inflammatory agents should be used cautiously in conjunction with corticosteroids in hypothrombinaemia.
Antidiabetics- Because corticosteroids may increase blood glucose concentrations, dosage adjustments of antidiabetic agents may be required. Antivirals - HIV protease inhibitors: Other immunosuppressants like cyclophosphamide and tacrolimus are substrates of CYP3A4. Potassium-depleting agents -When corticosteroids are administered concomitantly with potassium-depleting agents e.
There is also an increased risk of hypokalaemia with concurrent use of corticosteroids with amphotericin B, xanthenes, or beta2 agonists. Grapefruit juice — CYP3A4 inhibitor. Pregnancy The ability of corticosteroids to cross the placenta varies between individual drugs, however, methylprednisolone does cross the placenta.
One retrospective study found an increased incidence of low birth weights in infants born of mothers receiving corticosteroids.
Administration of corticosteroids to pregnant animals can cause abnormalities of foetal development including cleft palate, intra-uterine growth retardation and affects on brain growth and development. There is no evidence that corticosteroids result in an increased incidence of congenital abnormalities, such as cleft palate in man, however, when administered for long periods or repeatedly during pregnancy, corticosteroids may increase the risk of intra-uterine growth retardation.
Hypoadrenalism may, in theory, occur in the neonate following prenatal exposure to corticosteroids but usually resolves spontaneously following birth and is rarely clinically important.
Although neonatal adrenal insufficiency appears to be rare in infants who were exposed in utero to corticosteroids, those exposed to substantial doses of corticosteroids must be carefully observed and evaluated for signs of adrenal insufficiency. As with all drugs, corticosteroids should only be prescribed when the benefits to the mother and child outweigh the risks. When corticosteroids are essential, however, patients with normal pregnancies may be treated as though they were in the non-gravid state.
Cataracts have been observed in infants born to mothers treated with long-term corticosteroids during pregnancy. Breast-feeding Corticosteroids are excreted in small amounts in breast milk, however, doses of up to 40 mg daily of methylprednisolone are unlikely to cause systemic effects in the infant.
The amount of benzyl alcohol from medications is usually considered negligible compared to that received in flush solutions containing benzyl alcohol. Administration of high dosages of medications containing this preservative must take into account the total amount of benzyl alcohol administered.
The amount of benzyl alcohol at which toxicity may occur is not known. In order to minimize the incidence of dermal and subdermal atrophy , care must be exercised not to exceed recommended doses in injections. Injection into the deltoid muscle should be avoided because of a high incidence of subcutaneous atrophy.
Increased dosage of rapidly acting corticosteroids is indicated in patients on corticosteroid therapy who are subjected to any unusual stress before, during, and after the stressful situation.
Results from one multicenter, randomized, placebo-controlled study with methylprednisolone hemisuccinate, an intravenous 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.
Cardio-renal Average 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 the synthetic derivatives except 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 the 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. Endocrine Hypothalamic- 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.
The time to onset of this form of steroid -induced liver injury can be several weeks or longer. The desired dose may be administered intravenously over a period of several minutes. To prepare solutions for intravenous infusion, first prepare the solution for injection as directed.
Multiple Sclerosis In treatment of acute exacerbations of multiple sclerosis, daily doses of mg of prednisolone for a week followed by 80 mg every other day for 1 month have been shown to be effective 4 mg of methylprednisolone is equivalent to 5 mg of prednisolone.
Pediatric Methylprednisolone This product contains benzyl alcohol as a preservative. Persons who are on drugs which suppress the immune system are more susceptible to infections than healthy individuals. Elevation of creatine kinase may occur. Remission of musculoskeletal conditions may be permanent, or symptoms may recur, depending on the cause and extent methylprednisolone structural degeneration. Metabolic clearance of corticosteroids is decreased in hypothyroid patients and increased in hyperthyroid patients. The amount of benzyl alcohol at which toxicity may occur is not known. Corticosteroids may mask 40mg signs of infection and new infections may appear during their use.

Patients should also be advised that if they are exposed, medical advice should be sought without delay. Viral Infections Chicken 40mg and measles can have a more serious or even fatal course in pediatric and adult patients on corticosteroids. 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. Signs of peritoneal irritation following gastrointestinal perforation in patients receiving corticosteroids may be minimal or absent. The methylprednisolone effects of hypoglycaemic agents including insulinanti-hypertensives and diuretics are antagonised by corticosteroids, and the hypokalaemic 40mg of acetazolamide, loop diuretics, thiazide diuretics and carbenoxolone are enhanced.
This negative impact of corticosteroids on growth 40mg been observed at low systemic doses and in the absence of laboratory evidence of hypothalamic-pituitary-adrenal HPA axis suppression e. Areas not suitable for injection are those that are anatomically inaccessible such as spinal joints and those like the sacroiliac joints, which are devoid of synovial space. Blindness, exophthalmoses, glaucoma, increased intraocular pressure, ophthalmic inflammation ophthalmicsubcapsular posterior cataract, visual impairment Respiratory: This medication passes into breast milk. During prolonged corticosteroid therapy, these patients should receive chemoprophylaxis. Aspiration pneumonitis oral only ; asthma; berylliosis; fulminating or disseminated pulmonary tuberculosis when used concurrently with appropriate antituberculous chemotherapy; idiopathic eosinophilic pneumonias; symptomatic sarcoidosis. Inhaled corticosteroids are recommended for the treatment of asthma during pregnancy; however, systemic corticosteroids should be used to control acute exacerbations or treat severe persistent asthma ACOG ; GINA ; Namazy A 40mg to gauge needle for horses, to gauge needle for dogs, on a dry syringe is quickly inserted into methylprednisolone synovial space and a small amount of synovial fluid withdrawn. Bradycardia methylprednisolone been reported during or after the administration of large doses of methylprednisolone sodium succinate, methylprednisolone 40mg ml, and may be unrelated to the speed or duration of infusion. Palliative management of leukemias and lymphomas, methylprednisolone 40mg ml. Smaller spaces will require a correspondingly lesser dose.
If this complication occurs and diagnosis of sepsis is confirmed, methylprednisolone 40mg ml, appropriate antimicrobial therapy should be instituted. Ophthalmic Use of corticosteroids may produce posterior subcapsular cataracts, glaucoma with possible damage to the optic 40mg, and may enhance the establishment of secondary ocular infections due to bacteria, fungi, or viruses. Depo-Medrone vials are intended for single dose use only. Psychic derangements may appear when corticosteroids are used, methylprednisolone 40mg ml, ranging from euphoria, insomnia, mood swings, personality changes, methylprednisolone 40mg ml, and severe depression, to frank where can i buy phentermine uk manifestations. Cholestyramine Cholestyramine may increase the clearance of oral corticosteroids. The use of systemic corticosteroids is not recommended in the treatment of optic neuritis and may lead methylprednisolone an increase in the risk of new episodes. Inhaled corticosteroids are recommended for the treatment of asthma during pregnancy; however, systemic corticosteroids should be used to control acute exacerbations or treat severe persistent asthma Methylprednisolone ; 40mg ; Namazy Directions for Reconstitution 1. 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. Administration of high dosages of medications containing this preservative must take into account the total amount of benzyl alcohol administered. Initial dosage depends upon condition being treated; adjust subsequent doses based on patient response. Do not give acetate form IV.
