Gastrointestinal perforation has been reported in association with this combination. Aldesleukin: Corticosteroids may diminish the antineoplastic effect of Aldesleukin.

If no response within 3 days, discontinue treatment. Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.Initial high-dose “pulse” therapy for select indications (eg, severe systemic rheumatic disorders): 7 to 15 mg/kg/dose (or 500 mg to 1 g/dose) given once daily for 3 to 5 days.The following dosing is from the commercially available tapered-dosage product (eg, dose-pack containing 21 × 4 mg tablets):Day 1: 24 mg on day 1 administered as 8 mg (2 tablets) before breakfast, 4 mg (1 tablet) after lunch, 4 mg (1 tablet) after supper, and 8 mg (2 tablets) at bedtime Day 2: 20 mg on day 2 administered as 4 mg (1 tablet) before breakfast, 4 mg (1 tablet) after lunch, 4 mg (1 tablet) after supper, and 8 mg (2 tablets) at bedtime.Day 3: 16 mg on day 3 administered as 4 mg (1 tablet) before breakfast, 4 mg (1 tablet) after lunch, 4 mg (1 tablet) after supper, and 4 mg (1 tablet) at bedtime.Day 4: 12 mg on day 4 administered as 4 mg (1 tablet) before breakfast, 4 mg (1 tablet) after lunch, and 4 mg (1 tablet) at bedtime.Day 5: 8 mg on day 5 administered as 4 mg (1 tablet) before breakfast and 4 mg (1 tablet) at bedtime.Day 6: 4 mg on day 6 administered as 4 mg (1 tablet) before breakfast.Larger joint (eg, knee, shoulder, hip): 20 to 80 mg.Medium joint (eg, wrist, ankle, elbow): 10 to 40 mg.Usual dosage range: 20 to 60 mg; for large lesions, it may be necessary to distribute doses ranging from 20 to 40 mg by repeated local injections; 1 to 4 injections are usually employed with intervals between injections varying with the type of lesion being treated and clinical response.IV (succinate): Loading dose of 1 mg/kg over 30 minutes, followed by a gradual taper:Days 1 to 14: 1 mg/kg/day in divided doses or as a continuous infusion.Days 15 to 21: 0.5 mg/kg/day in divided doses or as a continuous infusion.Days 22 to 25: 0.25 mg/kg/day in divided doses or as a continuous infusion.Days 26 to 28: 0.125 mg/kg/day in divided doses or as a continuous infusion.IV (succinate): Initial: 60 to 80 mg; switch to an oral corticosteroid as soon as possible, tapering the dose for a total treatment duration of ≤10 days (EAACI [Zuberbier 2018]; Zuraw 2019).Oral: Initial: 16 to 32 mg/day in 1 to 2 divided doses for 3 to 4 days (Barniol 2018; Powell 2015; Zuraw 2019); may consider tapering the dose for a total treatment duration of ≤10 days (EAACI [Zuberbier 2018]; Zuraw 2019).Oral (preferred route), IV (succinate): 40 to 60 mg/day in 1 or 2 divided doses for 3 to 10 days (NAEPP 2007); doses up to 60 to 80 mg every 6 to 12 hours have been used in critically ill patients (Fanta 2019).
As more becomes known about these mechanisms, it may become possible to design treatment regimes that are more specific towards both the individual and the disease state. More specifically, Corticosteroids (Systemic) may increase protein catabolism and plasma ammonia concentrations, thereby increasing the doses of Urea Cycle Disorder Agents needed to maintain these concentrations in the target range. Hypoadrenalism may occur in newborns following maternal use of corticosteroids in pregnancy; monitor.When systemic corticosteroids are needed in pregnancy for rheumatic disorders, it is generally recommended to use the lowest effective dose for the shortest duration of time, avoiding high doses during the first trimester (Götestam Skorpen 2016; Makol 2011; Østensen 2009).For dermatologic disorders in pregnant women, systemic corticosteroids are generally not preferred for initial therapy; should be avoided during the first trimester; and used during the second or third trimester at the lowest effective dose (Bae 2012; Leachman 2006).Uncontrolled asthma is associated with adverse events on pregnancy (increased risk of perinatal mortality, preeclampsia, preterm birth, low birth weight infants, cesarean delivery, and the development of gestational diabetes).
