Infection Risks and Precautions
Chickenpox and measles can be severe or even fatal in individuals taking steroid medications like this one. Avoid exposure to these diseases if you have not had them before, and if you have been exposed, notify your doctor immediately. Steroid medications increase the risk of infection, which can be mild or severe. The risk is higher with higher doses. To minimize your risk, wash your hands frequently, avoid people with infections, colds, or flu, and notify your doctor if you experience any signs of infection.
Some infections, such as tuberculosis and hepatitis B, may reactivate in patients taking this medication. If you have a history of these infections, inform your doctor. This medication may decrease your body's natural steroid production. If you experience a fever, infection, undergo surgery, or are injured, consult with your doctor, as you may need additional oral steroids to help your body cope with stress. Carry a warning card indicating that you may require extra steroids in certain situations.
Stopping the Medication and Special Considerations
If you have been taking this medication for an extended period, consult with your doctor before stopping, as you may need to taper off the medication gradually. If you miss a dose or recently stopped taking this medication and experience fatigue, weakness, shakiness, rapid heartbeat, confusion, sweating, or dizziness, notify your doctor.
Long-term use of this medication has been associated with an increased risk of Kaposi's sarcoma, a type of cancer. Discuss this with your doctor. If you have or may have pheochromocytoma, inform your doctor, as this medication can have severe and potentially fatal effects in individuals with this condition.
Patients with cancer may be at a higher risk of developing tumor lysis syndrome (TLS), a potentially life-threatening condition. Discuss this with your doctor. If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects.
This medication may affect growth in children and adolescents; they may require regular growth checks. If the patient is a premature infant, discuss the potential risks with your doctor, as a specific heart problem has been reported in this population.
Pregnancy, Breastfeeding, and Adrenal Function
If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the benefits and risks of this medication with your doctor. If you used this medication during pregnancy, inform your baby's doctor.
For individuals with poor adrenal function, stopping this medication, taking too low of a dose, or switching between different forms of this medication can lead to severe and potentially life-threatening adrenal gland problems. If you have questions or concerns, consult with your doctor.
Overdose Information
Overdose Symptoms:
- Acute overdose is rare but may include: fluid retention, hypertension, hypokalemia, hyperglycemia, and psychiatric disturbances. Chronic overdose leads to Cushingoid features (moon face, buffalo hump, central obesity).
What to Do:
Seek immediate medical attention. Call 911 or your local emergency number. For advice, call a poison control center at 1-800-222-1222.
Drug Interactions
Contraindicated Interactions
- Live or live attenuated vaccines (in immunosuppressed patients)
Major Interactions
- CYP3A4 inducers (e.g., rifampin, phenytoin, barbiturates, carbamazepine): May decrease hydrocortisone levels, requiring dose increase.
- CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir, clarithromycin): May increase hydrocortisone levels, requiring dose reduction.
- NSAIDs (e.g., ibuprofen, naproxen): Increased risk of gastrointestinal ulceration and bleeding.

- Vaccines (inactivated): Reduced immune response to vaccines.
Minor Interactions
- Grapefruit juice: May slightly increase hydrocortisone levels (CYP3A4 inhibition).
Monitoring
Baseline Monitoring
Rationale: To confirm diagnosis of adrenal insufficiency or assess baseline adrenal axis function.
Timing: Prior to initiation for adrenal insufficiency; as clinically indicated for other uses.
Rationale: To establish baseline and monitor for mineralocorticoid effects (sodium retention, potassium loss).
Timing: Prior to initiation.
Rationale: To establish baseline and monitor for glucocorticoid-induced hyperglycemia.
Timing: Prior to initiation.
Rationale: To establish baseline and monitor for hypertension.
Timing: Prior to initiation.
Rationale: For patients on long-term therapy to assess osteoporosis risk.
Timing: Prior to initiation for anticipated long-term use.
Routine Monitoring
Frequency: Periodically, especially during dose changes or intercurrent illness.
Target: Within normal limits
Action Threshold: Significant deviations (e.g., hypokalemia, hypernatremia) require intervention.
Frequency: Periodically, more frequently in diabetic patients or those at risk.
Target: Individualized, typically non-diabetic ranges
Action Threshold: Persistent hyperglycemia requires intervention (e.g., diet, antidiabetic medication adjustment).
Frequency: Regularly, especially during initial therapy and dose adjustments.
Target: Individualized, typically <130/80 mmHg
Action Threshold: Sustained hypertension requires intervention.
Frequency: Regularly (e.g., every 3-6 months).
Target: Normal growth velocity for age
Action Threshold: Growth retardation may necessitate dose reduction or alternative therapy.
Frequency: Annually for long-term therapy.
Target: Normal intraocular pressure
Action Threshold: Elevated pressure may indicate glaucoma.
Frequency: Every 1-2 years for long-term therapy.
Target: Stable or improving BMD
Action Threshold: Significant bone loss may require osteoporosis treatment.
Symptom Monitoring
- Signs of infection (fever, sore throat, malaise)
- Gastrointestinal upset (abdominal pain, black/tarry stools)
- Mood changes (irritability, depression, euphoria)
- Fluid retention (swelling in ankles/feet, weight gain)
- Muscle weakness or pain
- Vision changes
- Skin changes (thinning, bruising)
- Signs of adrenal crisis (severe fatigue, weakness, dizziness, nausea, vomiting, low blood pressure) if abruptly discontinued
Special Patient Groups
Pregnancy
Category C. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Hydrocortisone crosses the placenta. High doses or prolonged use may lead to fetal adrenal suppression, requiring monitoring of the neonate.
Trimester-Specific Risks:
Lactation
Considered compatible with breastfeeding at typical therapeutic doses. Hydrocortisone is excreted into breast milk in small amounts. Monitor infant for signs of adrenal suppression (e.g., poor weight gain, irritability) with high maternal doses or prolonged use.
Pediatric Use
Children are more susceptible to growth retardation and suppression of the hypothalamic-pituitary-adrenal (HPA) axis. Monitor growth and development closely. Alternate day therapy may be considered to minimize HPA axis suppression. Increased risk of intracranial hypertension in children.
Geriatric Use
Elderly patients may be at increased risk for adverse effects such as osteoporosis, hypertension, diabetes, and fluid retention. Use the lowest effective dose for the shortest duration possible. Monitor closely for side effects.
Clinical Information
Clinical Pearls
- Always advise patients not to abruptly discontinue hydrocortisone, especially after prolonged use, due to the risk of adrenal crisis.
- For adrenal insufficiency, emphasize the importance of stress dosing (increasing dose during illness, surgery, or severe stress).
- Educate patients on signs of infection, as corticosteroids can mask symptoms and increase susceptibility.
- Recommend taking hydrocortisone in the morning or divided doses (e.g., 2/3 AM, 1/3 PM) to mimic natural cortisol secretion and minimize sleep disturbances.
- Long-term use requires monitoring for bone density, blood glucose, blood pressure, and ophthalmologic changes.
Alternative Therapies
- Other glucocorticoids (e.g., prednisone, methylprednisolone, dexamethasone) for anti-inflammatory/immunosuppressive indications.
- Fludrocortisone (for mineralocorticoid replacement in adrenal insufficiency).
- Non-steroidal anti-inflammatory drugs (NSAIDs) for inflammatory conditions (less potent).
- Disease-modifying antirheumatic drugs (DMARDs) or biologics for autoimmune diseases (long-term management).
