Hisone (Hydrocortisone)

Hisone is prescribed for several endocrine and inflammatory conditions where glucocorticoid replacement or suppression is required.

• Adrenal insufficiency, including primary (Addison’s disease) and secondary forms.
• Acute exacerbations of chronic asthma or chronic obstructive pulmonary disease (COPD) when systemic therapy is indicated.
• Management of severe allergic reactions or urticaria unresponsive to antihistamines.
• Treatment of autoimmune disorders such as rheumatoid arthritis, systemic lupus erythematosus, or inflammatory bowel disease.
• Replacement therapy in patients receiving long‑term corticosteroid tapering.
• Short‑term use for adrenal crisis management during major stress, surgery, or trauma.

• Hydrocortisone exerts its pharmacologic activity by binding to intracellular glucocorticoid receptors, forming a receptor‑ligand complex that translocates to the nucleus. The complex interacts with glucocorticoid response elements on DNA, modulating transcription of anti‑inflammatory proteins such as annexin‑1 and suppressing pro‑inflammatory cytokines including interleukin‑1, interleukin‑6, and tumor necrosis factor‑α. This genomic effect reduces leukocyte migration and stabilizes lysosomal membranes, producing systemic anti‑inflammatory and immunosuppressive actions.

Like other systemic glucocorticoids, hydrocortisone can cause a range of adverse reactions that vary in frequency and severity.

Common

• Increased appetite or weight gain.
• Mild gastrointestinal discomfort or dyspepsia.
• Fluid retention leading to peripheral edema.
• Mood changes such as irritability or mild insomnia.
• Skin thinning or easy bruising.
• Acne or other dermatologic changes.
• Increased susceptibility to upper respiratory tract infections.

Serious

• Severe hyperglycemia or new‑onset diabetes mellitus.
• Significant hypertension or cardiovascular events.
• Suppression of the hypothalamic‑pituitary‑adrenal (HPA) axis causing adrenal insufficiency on abrupt discontinuation.
• Osteoporosis or increased risk of fractures.
• Severe infections due to immunosuppression.
• Visual disturbances such as cataracts or glaucoma.

When prescribing Hisone, clinicians consider several precautionary measures to minimize risks and ensure safe use.

• Assess baseline blood pressure, glucose, and electrolyte status before initiating therapy.
• Evaluate for active infections; avoid use in uncontrolled bacterial, viral, or fungal infections.
• Use the lowest effective dose for the shortest duration to reduce systemic exposure.
• Monitor for signs of adrenal suppression, especially during tapering or abrupt discontinuation.
• Caution in patients with a history of peptic ulcer disease or gastrointestinal bleeding.
• Consider bone health assessment in long‑term users.
• Discuss potential mood or psychiatric effects with patients and caregivers.

Hydrocortisone may interact with other medicines, altering its effectiveness or increasing the risk of adverse events.

Avoid

• Concurrent use of potent CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin) that can raise systemic hydrocortisone levels.
• Co‑administration with other systemic glucocorticoids, which may amplify immunosuppression and metabolic effects.

Use with caution

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) may increase the risk of gastrointestinal ulceration.
• Antidiabetic agents may require dose adjustment due to hydrocortisone‑induced hyperglycemia.
• Antihypertensive medications, especially ACE inhibitors or diuretics, may need monitoring for fluid retention and blood pressure changes.
• Vaccines, particularly live attenuated vaccines, should be administered with caution because of possible reduced immune response.
