Monitor for increased signs and/or symptoms of hypercorticism; discontinue use if signs or symptoms are observed.

Rectal enema [Canadian product]: There are no dosage adjustments provided in the manufacturer's labeling.

Reconstitution

Enema [Canadian product]: Remove nozzle and protective cap from enema bottle; place one dispersible tablet into enema bottle. Place nozzle back on the bottle, ensure protective cap is secured, then shake bottle vigorously for at least 10 seconds or until tablet is completely dissolved (suspension should turn slightly yellowish). Volume of reconstituted enema is 115 mL.

Administration

Rectal: Rectal foam: For rectal use only; not for oral use. Wash hands before and after use. Prior to use, patients should use the bathroom to empty the bowel. Attach applicator to canister nozzle. Each applicator is coated with a lubricant. If additional lubrication is needed, petrolatum or petroleum jelly can also be used. Warm the canister in the hands while shaking it vigorously for 10 to 15 seconds prior to use. Unlock the canister by twisting the domed canister top until it is aligned with the nozzle. May be used in a standing, lying or sitting position (eg, while sitting on the toilet). Turn the canister upside down and gently insert applicator tip into rectum as far as is comfortable. Push down on the pump dome with forefinger and hold for 2 seconds; release finger pressure on pump dome and hold applicator in place for 10 to 15 seconds. Only use applicator provided by manufacturer; do not insert any part of the aerosol container in the rectum. After administering, withdraw and discard the used applicator in provided plastic trash bag. Evening doses should be applied immediately prior to bedtime. Patient should try not to empty the bowel again until the next morning. Avoid fire, flame and smoking during and immediately following administration. Temporarily discontinue use before initiation of bowel preparation for colonoscopy; consult provider prior to resuming therapy.

Rectal enema [Canadian product]: For rectal use only; not for oral use. Patient should lie down on left side, shake the reconstituted enema bottle, remove protective cap and then empty contents into rectum. Patient should roll over on stomach and remain in this position for 5 minutes, then lie in a comfortable position. Enema should be retained the whole night if possible or as long as possible.

Dietary Considerations

Avoid consumption of grapefruit or grapefruit juice during treatment

Storage

Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Do not expose to heat or store at temperatures above 49°C (120°F). Do not refrigerate.

Enema [Canadian product]: Store at 15°C to 30°C (59°F to 86°F). Use immediately after preparation.

Drug Interactions

Aldesleukin: Corticosteroids may diminish the antineoplastic effect of Aldesleukin. Avoid combination

Corticorelin: Corticosteroids may diminish the therapeutic effect of Corticorelin. Specifically, the plasma ACTH response to corticorelin may be blunted by recent or current corticosteroid therapy. Monitor therapy

CYP3A4 Inhibitors (Moderate): May increase the serum concentration of Budesonide (Topical). Management: Per US prescribing information, avoid this combination. Canadian product labeling does not recommend strict avoidance. If combined, monitor for excessive glucocorticoid effects as budesonide exposure may be increased. Consider therapy modification

CYP3A4 Inhibitors (Strong): May increase the serum concentration of Budesonide (Topical). Management: Per US prescribing information, avoid this combination. Canadian product labeling does not recommend strict avoidance. If combined, monitor for excessive glucocorticoid effects as budesonide exposure may be increased. Consider therapy modification

Deferasirox: Corticosteroids may enhance the adverse/toxic effect of Deferasirox. Specifically, the risk for GI ulceration/irritation or GI bleeding may be increased. Monitor therapy

Hyaluronidase: Corticosteroids may diminish the therapeutic effect of Hyaluronidase. Management: Patients receiving corticosteroids (particularly at larger doses) may not experience the desired clinical response to standard doses of hyaluronidase. Larger doses of hyaluronidase may be required. Consider therapy modification

Adverse Reactions

Frequency not always defined.

>10%: Endocrine & metabolic: Decreased plasma cortisol (17%)

1% to 10%:

Warnings/Precautions

Concerns related to adverse effects:

• Adrenal suppression: May cause hypercorticism or suppression of hypothalamic-pituitary-adrenal (HPA) axis, particularly in patients receiving high doses for prolonged periods, or with concomitant CYP3A4 inhibitor use. HPA axis suppression may lead to adrenal crisis. Withdrawal and discontinuation of a corticosteroid should be done slowly and carefully. In situations where patients are subject to surgery or other stress situations, supplementation with systemic glucocorticoids is recommended.

• Impaired adrenal suppression in patients transferred from other glucocorticoids: Monitor patients transferred from systemic corticosteroids to corticosteroids with lower systemic effects (eg rectal foam), since steroid withdrawal, including benign intracranial hypertension or acute adrenal suppression, may occur. Replacement of systemic corticosteroids with rectal foam may unmask allergies (eg, rhinitis and eczema) previously controlled by systemic drug. Adrenocortical function monitoring may be required in these patients; reduce dose cautiously.

• Immunosuppression: Prolonged use of corticosteroids may also increase the incidence of secondary infection, mask acute infection (including fungal infections), prolong or exacerbate viral infections, or limit response to vaccines. Exposure to chickenpox should be avoided; if exposed, therapy with varicella zoster immune globulin (VZIG) or pooled intravenous immunoglobulin (IVIG) may be needed; antivirals may be needed if chickenpox develops. Exposure to measles may require pooled intramuscular immunoglobulin use. Corticosteroids should not be used to treat ocular herpes simplex. Corticosteroids should not be used for viral hepatitis. Close observation is required in patients with latent tuberculosis and/or TB reactivity; restrict use in active TB (only in conjunction with antituberculosis treatment). Use of Entocort enema [Canadian product] in patients with active TB is contraindicated.

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with hypertension, acute coronary disease, or limited cardiac reserve.

• Diabetes: Use with caution in patients with diabetes or a family history of diabetes; may alter glucose production/regulation leading to hyperglycemia.

• Gastrointestinal disease: Use with caution in patients with peptic ulcer disease. Use budesonide enema [Canadian product] with caution in patients with diverticulitis or severe ulcerative colitis (perforation risk).

• Hepatic impairment: Use with caution in patients with hepatic impairment, including cirrhosis; increased oral bioavailability has been reported in patients with cirrhosis.

• Myasthenia gravis: Use with caution; exacerbation of symptoms has occurred especially during initial treatment with systemic corticosteroids.

• Ocular disease: Use with caution in patients with cataracts and/or glaucoma or a family history of these diseases; increased intraocular pressure, open-angle glaucoma, and cataracts have occurred with prolonged glucocorticoid use.

• Osteoporosis: Use with caution in patients with osteoporosis; high doses and/or long-term use of corticosteroids have been associated with increased bone loss and osteoporotic fractures.

• Psychiatric disturbances: Systemic corticosteroid use may cause psychiatric disturbances, including depression, euphoria, insomnia, mood swings, and personality changes. Preexisting psychiatric conditions may be exacerbated by corticosteroid use.

• Thyroid disease: Metabolic clearance of corticosteroids increases in hyperthyroid patients and decreases in hypothyroid patients.

Concurrent therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Elderly: Because of the risk of adverse effects, corticosteroids should be used cautiously in the elderly in the smallest possible effective dose for the shortest duration.

Dosage form specific issues:

• Flammable contents: Rectal foam contains flammable propellants. Avoid fire, flame and smoking during and immediately following administration. Temporarily discontinue use before initiation of bowel preparation for colonoscopy; consult health care provider prior to resuming therapy.

Monitoring Parameters

Baseline hepatic function tests; serum glucose, electrolytes; presence of infection, signs/symptoms of hypercorticism as clinically indicated

Pregnancy Risk Factor

C

Pregnancy Considerations

Adverse events were observed in some animal reproduction studies. Hypoadrenalism may occur in newborns following maternal use of corticosteroids in pregnancy; monitor. Oral budesonide has been used for the induction of remission in pregnant women with inflammatory bowel disease (Habal, 2012).

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience flatulence, diarrhea, or nausea. Have patient report immediately to prescriber signs of high blood sugar (confusion, fatigue, increased thirst, increased hunger, polyuria, flushing, fast breathing, or breath that smells like fruit), signs of skin changes (acne, stretch marks, slow healing, or hair growth), signs of infection, buffalo hump, moon face, ankle edema, severe loss of strength and energy, dizziness, passing out, severe nausea, severe vomiting, bruising, bleeding, vision changes, joint pain, or bone pain (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
