Glucort100 mg/2 ml

Glucort 100 mg/2 ml is the pharmaceutical form of cortisol, the body's natural glucocorticoid hormone, and is marketed in several distinct formulations (oral, topical, rectal, and injectable) with different approved uses. The generic name alone does not identify which formulation and route a specific product represents; always confirm this on the product's own label.

Oral and Injectable (Systemic) Use

• Adrenal insufficiency (primary or secondary) - as hormone replacement therapy for the body's own inadequate cortisol production, including Addison's disease and congenital adrenal hyperplasia
• Acute adrenal crisis - a life-threatening emergency requiring urgent high-dose injectable Glucort 100 mg/2 ml
• Severe allergic reactions, status asthmaticus, and other acute inflammatory or allergic conditions not responding to conventional treatment
• Stress dosing - a temporarily increased dose during illness, injury, or surgery in patients already on Glucort 100 mg/2 ml replacement, to mimic the body's natural increased cortisol output during physical stress

Topical Use

• Relief of redness, swelling, itching, and discomfort associated with various inflammatory skin conditions, including eczema, contact dermatitis, and insect bite reactions

Rectal Use

• Adjunctive treatment of ulcerative proctitis and related inflammatory conditions of the rectum

Contains Glucort 100 mg/2 ml (or, for some injectable products, Glucort 100 mg/2 ml sodium succinate or Glucort 100 mg/2 ml sodium phosphate) as the active ingredient. Marketed forms include oral tablets (commonly 5 mg, 10 mg, and 20 mg), oral granules for pediatric use, topical creams/ointments/lotions (commonly 0.5%-2.5%), rectal foam or suppositories, and injectable solutions for intravenous or intramuscular use (strength varies by product). The generic name alone does not identify a single formulation, strength, or route; always confirm the specific product's form and strength on its own label.

Glucort 100 mg/2 ml is identical to cortisol, the glucocorticoid hormone naturally produced by the adrenal glands. It is used both as replacement therapy in people whose adrenal glands do not make enough of this hormone, and, at higher doses in different formulations, as an anti-inflammatory and immune-suppressing treatment for various allergic, inflammatory, and skin conditions. Because Glucort 100 mg/2 ml is marketed across very different formulations - oral tablets for adrenal replacement, topical creams for skin conditions, and injectable forms for emergencies - the appropriate dose, frequency, and clinical use depend entirely on which specific product and route is being used.

Therapeutic Class: Corticosteroid (Glucocorticoid) / Adrenal Hormone Replacement

Glucort 100 mg/2 ml has a short biological half-life (approximately 1.5-2 hours), which is why oral replacement therapy for adrenal insufficiency generally requires two to three doses daily to approximate the body's natural cortisol rhythm, with the largest dose typically given first thing in the morning to mirror the normal diurnal peak. Systemic absorption from topical use is generally low on intact skin but increases significantly on damaged skin, in skin folds, in infants, or with occlusive dressings.

Oral

• Take the first (largest) dose immediately upon waking, and subsequent doses at intervals through the day as directed, with the last dose generally 4-6 hours before bedtime to avoid disrupting sleep
• May be taken with or without food

Topical

• Apply a thin layer to the affected skin area only, gently rubbing in
• Wash hands after application unless treating the hands
• Do not use on broken skin, infected areas, or under an occlusive dressing/bandage unless specifically directed by a doctor

Injectable

• Administered by intravenous or intramuscular injection by a healthcare professional, typically in a hospital or emergency setting

The following should be assessed by a healthcare professional before combining with Glucort 100 mg/2 ml, particularly at systemic (oral or injectable) doses:

• NSAIDs and aspirin: combined use increases the risk of gastrointestinal ulceration and bleeding.
• Drugs affecting CYP3A4 (such as ketoconazole, rifampicin, phenytoin): can alter Glucort 100 mg/2 ml blood levels, requiring dose adjustment.
• Potassium-depleting diuretics: increase the risk of low blood potassium when combined with corticosteroids.
• Anticoagulants such as warfarin: corticosteroids can alter anticoagulant effect, requiring closer monitoring.
• Live vaccines: should generally be avoided during systemic corticosteroid therapy due to immune suppression.
• Antidiabetic medicines: systemic Glucort 100 mg/2 ml can raise blood glucose, potentially requiring adjustment of diabetes treatment.

Common side effects (systemic/oral use)

• Fluid retention, mild swelling
• Raised blood glucose
• Increased appetite
• Mood changes, sleep disturbance
• Indigestion

Common side effects (topical use)

• Local burning, stinging, or itching on application
• Skin thinning with prolonged use

Serious side effects (seek medical attention)

• Signs of infection that may be masked by the corticosteroid's anti-inflammatory effect
• Signs of adrenal suppression if stopped abruptly after prolonged systemic use: severe fatigue, weakness, low blood pressure, nausea
• Signs of Cushing's syndrome with prolonged, excessive dosing: weight gain (particularly central/facial), stretch marks, easy bruising
• Vision changes, which may indicate raised eye pressure with prolonged systemic use

Pregnancy

Glucort 100 mg/2 ml crosses the placenta in small amounts; systemic use during pregnancy should occur under medical guidance, weighing the benefit of treating adrenal insufficiency or a serious inflammatory condition against any potential risk, particularly with high-dose or prolonged therapy. Topical use on limited skin areas carries a much lower systemic exposure.

Breastfeeding

Glucort 100 mg/2 ml is excreted in human milk in small amounts; systemic use during breastfeeding should be discussed with a healthcare professional, while topical use on limited areas, away from the breast, is generally considered lower risk.

• Never stop systemic (oral) Glucort 100 mg/2 ml abruptly after regular use, as this can precipitate a life-threatening adrenal crisis; any dose reduction must be gradual and medically supervised.
• Sick-day rules: patients on Glucort 100 mg/2 ml replacement therapy should be educated on increasing their dose during illness, fever, or before surgical procedures, and on when to seek emergency injectable treatment.
• Medical alert identification: patients dependent on Glucort 100 mg/2 ml replacement should carry medical identification (such as a bracelet) and an emergency injection kit where advised by their endocrinologist.
• Topical use: avoid prolonged use on the face, in skin folds, or under occlusive dressings, given increased absorption and skin-thinning risk in these areas.
• Monitor blood glucose, blood pressure, and signs of infection during systemic use, particularly with higher doses or longer courses.

Acute overdose of Glucort 100 mg/2 ml is unlikely to be immediately life-threatening in most cases, but repeated excessive dosing over time can worsen effects such as fluid retention, raised blood glucose, mood disturbance, and increased infection susceptibility (Cushing's syndrome with prolonged excess). If overdose is suspected, particularly involving injectable or high-dose oral Glucort 100 mg/2 ml, contact a doctor or poison control center; management is generally supportive.

Oral tablets and granules: store at room temperature (15-30°C), with brief excursions in this range acceptable during transport. Topical creams/ointments: store at room temperature as directed on the label, away from excessive heat. Injectable forms: store as directed by the manufacturer, generally at room temperature and protected from light; use reconstituted or diluted solutions promptly per the product's stability instructions.

• Infants and children with adrenal insufficiency: Weight-based dosing, often using specially formulated oral granules or liquid preparations for accurate low-dose administration; regular monitoring of growth is important with long-term use.
• Elderly: May be more susceptible to skin thinning (topical use) and to metabolic effects (systemic use); use the lowest effective dose.
• Patients undergoing surgery: Those on Glucort 100 mg/2 ml replacement require perioperative "stress dose" adjustment, coordinated with the anaesthesia and surgical team.

For adrenal insufficiency, Glucort 100 mg/2 ml replacement is typically lifelong. For acute allergic or inflammatory conditions, systemic use is generally short-term, tapered as the condition improves. Topical use for skin conditions is generally limited to short courses (days to a few weeks), with longer use reserved for chronic conditions under medical supervision, given the skin-thinning risk with prolonged application.

Injectable powder formulations (such as Glucort 100 mg/2 ml sodium succinate) require reconstitution with the diluent specified by the manufacturer immediately before use, following the specific product's instructions for volume and resulting concentration. Reconstituted solution should be used promptly per the manufacturer's stability data.

Drug Class: Short-acting glucocorticoid (naturally occurring cortisol)

Glucort 100 mg/2 ml binds to glucocorticoid receptors throughout the body, where it regulates gene expression involved in inflammation, immune response, and metabolism. In adrenal insufficiency, it replaces the body's own missing cortisol, restoring normal metabolic and stress-response function. At higher, pharmacologic doses (well above the body's natural replacement needs), it suppresses inflammation and immune activity, which is the basis for its use in allergic and inflammatory conditions, and, topically, for reducing skin inflammation and itching.

Glucort 100 mg/2 ml is used in infants and children for adrenal insufficiency (including congenital adrenal hyperplasia) and various inflammatory and allergic conditions, with dosing individualized by weight and age; specially formulated low-dose granules or liquid preparations are often used in this population to allow accurate dosing, since crushed adult tablets do not reliably provide the small, precise doses often needed. Growth should be monitored regularly with long-term use.
