Lilinorm (Hydrocortisone)

Hydrocortisone acts on the endocrine and inflammatory pathways to restore glucocorticoid balance and suppress excess inflammation.

• Adrenal insufficiency: replaces deficient cortisol and prevents adrenal crisis.
• Congenital adrenal hyperplasia: provides glucocorticoid control of excess androgen production.
• Inflammatory conditions: reduces inflammation and symptom severity in disorders such as rheumatoid arthritis or severe dermatitis.

• Hydrocortisone binds to intracellular glucocorticoid receptors, forming a complex that translocates to the nucleus and modulates gene transcription. This interaction up‑regulates anti‑inflammatory proteins and down‑regulates pro‑inflammatory cytokines, resulting in reduced immune cell activation, decreased vascular permeability, and suppression of the hypothalamic‑pituitary‑adrenal axis when used exogenously.

Hydrocortisone may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Hyperglycemia: elevated blood sugar levels.
• Fluid retention: swelling of the ankles or face.
• Hypertension: increased blood pressure.
• Mood changes: irritability or euphoria.
• Gastrointestinal upset: nausea or abdominal discomfort.
• Weight gain: increased appetite and fat deposition.

Serious or Rare Side Effects

• Adrenal suppression: reduced endogenous cortisol production.
• Severe infection: heightened susceptibility to bacterial, viral or fungal infections.
• Cushingoid appearance: moon face, central obesity, skin thinning.
• Osteoporosis: loss of bone density with prolonged use.
• Psychosis or severe mood disorders.
• Anaphylaxis: rare but potentially life‑threatening allergic reaction.

Before initiating therapy, clinicians should evaluate individual risk factors and monitor patients regularly.

• Assess adrenal function: confirm need for glucocorticoid replacement.
• Monitor blood glucose: adjust antidiabetic therapy as needed.
• Monitor blood pressure: watch for hypertension development.
• Use the lowest effective dose: limit duration to reduce adverse effects.
• Avoid abrupt discontinuation: taper gradually to prevent withdrawal.
• Store at ambient temperature: keep in the original pack, protect from moisture.

Hydrocortisone can alter the activity of several co‑administered medicines, requiring careful management.

Major Interactions (Avoid)

• Strong CYP3A4 inhibitors (e.g., ketoconazole): may increase systemic exposure.
• Anticoagulants (e.g., warfarin): enhanced anticoagulant effect.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs): increased risk of gastrointestinal bleeding.
• Live vaccines: reduced vaccine efficacy.
• Loop diuretics: may exacerbate hypokalemia.

Moderate Interactions (Monitor Closely)

• CYP3A4 inducers (e.g., rifampin): may reduce hydrocortisone levels.
• Antidiabetic agents (e.g., insulin): may require dose adjustment for hyperglycemia.
• Antihypertensives: possible reduction in blood‑pressure control.
• Anticonvulsants (e.g., phenytoin): may lower glucocorticoid effect.
• Antifungal azoles (e.g., fluconazole): may modestly increase exposure.
