Hydrocortisonum-Sf (Hydrocortisone)

Hydrocortisonum‑Sf is prescribed for several endocrine and inflammatory conditions where systemic glucocorticoid activity is required.

• Replacement therapy in primary or secondary adrenal insufficiency.
• Management of acute adrenal crisis.
• Adjunctive treatment of inflammatory or autoimmune disorders such as rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease.
• Short‑term control of severe allergic reactions or skin disorders when oral therapy is preferred.
• Supportive therapy in certain oncologic protocols that involve steroid pre‑medication.

• Hydrocortisonum‑Sf delivers hydrocortisone, which binds to intracellular glucocorticoid receptors and translocates to the nucleus. The receptor‑ligand complex interacts with glucocorticoid response elements on DNA, modulating transcription of multiple genes. This results in decreased synthesis of pro‑inflammatory cytokines, inhibition of phospholipase A2, and reduced expression of adhesion molecules, collectively producing anti‑inflammatory and immunosuppressive effects while also supporting cortisol‑dependent metabolic pathways.

Oral hydrocortisone may cause a range of adverse reactions, varying from mild and transient to potentially serious.

Common

• Increased appetite or mild weight gain.
• Gastrointestinal discomfort such as nausea.
• Fluid retention causing mild peripheral edema.

Serious

• Significant hyperglycemia or new‑onset diabetes.
• Suppression of the hypothalamic‑pituitary‑adrenal axis, risking adrenal insufficiency.
• Opportunistic infections due to immunosuppression.

Before initiating Hydrocortisonum‑Sf, clinicians should evaluate several safety considerations to minimize risk.

• Assess for active infections; avoid systemic glucocorticoids in uncontrolled bacterial, viral, or fungal infections.
• Review history of hypertension, diabetes, or osteoporosis, as hydrocortisone may exacerbate these conditions.
• Evaluate for known hypersensitivity to hydrocortisone or any excipients.
• Use the lowest effective dose for the shortest duration needed to achieve therapeutic goals.
• Monitor serum electrolytes, glucose, and blood pressure regularly during treatment.
• Consider stress‑dosing protocols in patients with adrenal insufficiency undergoing surgery or trauma.

Hydrocortisonum‑Sf can alter the pharmacokinetics or pharmacodynamics of several other medicines; awareness of these interactions helps guide safe co‑administration.

Avoid

• Strong CYP3A4 inducers such as rifampin, phenytoin, or carbamazepine, which may reduce hydrocortisone exposure.
• Live vaccines, because systemic steroids can diminish vaccine efficacy and increase infection risk.

Use with caution

• Antidiabetic agents, as hydrocortisone may raise blood glucose and require dose adjustment.
• Antihypertensive drugs, particularly ACE inhibitors or diuretics, due to potential fluid retention and blood pressure changes.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs), which together may increase risk of gastrointestinal ulceration.
• Anticoagulants like warfarin, where glucocorticoids can affect coagulation parameters.
