This list is not exhaustive, and it is crucial to discuss all your medications (prescription and over-the-counter), natural products, vitamins, and health issues with your doctor and pharmacist. They will help determine if it is safe to take this medication in combination with your other medications and health conditions.
Remember, do not start, stop, or adjust the dosage of any medication without first consulting your doctor to ensure your safety.
Precautions & Cautions
This medication may interfere with allergy skin tests, so be sure to notify your doctor and laboratory personnel that you are taking it. Long-term use of this medication may increase the risk of developing cataracts or glaucoma, so it is crucial to discuss this with your doctor.
Prolonged use of this medication can also lead to weak bones (osteoporosis). Your doctor can help determine if you are at higher risk of developing osteoporosis and answer any questions you may have. You may need to reduce your salt intake and take potassium supplements, so consult with your doctor about this.
If you have diabetes, it is vital to closely monitor your blood sugar levels while taking this medication. Before consuming alcohol, discuss the potential risks with your doctor. Additionally, if you regularly drink grapefruit juice or eat grapefruit, talk to your doctor about potential interactions.
Do not exceed the prescribed dose of this medication, as taking more than recommended can increase the risk of severe side effects. Before receiving any vaccines, consult with your doctor, as some vaccines may not be effective or may increase the risk of infection when taken with this medication.
If you have not had chickenpox or measles before, avoid close contact with anyone who has these conditions, as they can be severe or even life-threatening in people taking steroid medications like this one. If you have been exposed to chickenpox or measles, inform your doctor immediately.
Steroid medications, including this one, can increase the risk of infection, which can be mild or severe. They can also make it more challenging to recognize the signs of infection. To minimize the risk of infection, wash your hands frequently, avoid close contact with people who have infections, colds, or flu, and notify your doctor if you experience any symptoms of infection.
In some cases, this medication can reactivate latent infections, such as tuberculosis or hepatitis B. If you have a history of these infections, inform your doctor. This medication can also lower the levels of natural steroids in your body. If you experience a fever, infection, surgery, or injury, consult with your doctor, as you may require additional oral steroid doses to help your body cope with these stresses. Carry a warning card indicating that you may need extra steroids in certain situations.
If you have been taking this medication for an extended period, do not stop taking it without consulting your doctor, as this can lead to withdrawal symptoms. If you miss a dose or recently stopped taking this medication and experience fatigue, weakness, shakiness, rapid heartbeat, confusion, sweating, or dizziness, inform your doctor promptly.
Long-term use of this medication has been associated with an increased risk of developing Kaposi's sarcoma, a type of cancer. Discuss this risk with your doctor. If you have or may have pheochromocytoma, a rare condition, inform your doctor, as this medication can have severe and potentially life-threatening effects in people with this condition.
Patients with cancer may be at higher risk of developing tumor lysis syndrome (TLS), a potentially life-threatening condition. Discuss this risk 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 can affect growth in children and adolescents, so regular growth checks may be necessary. If you are a premature infant, inform your doctor, as this medication can increase the risk of a specific heart problem.
If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the benefits and risks of this medication with your doctor. If you took 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 dose forms 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 Cushingoid features (moon face, buffalo hump) with chronic overdose.
What to Do:
Seek immediate medical attention. Call 911 or Poison Control at 1-800-222-1222. Treatment is generally supportive and symptomatic. Chronic overdose requires gradual withdrawal of the drug under medical supervision.
Drug Interactions
Contraindicated Interactions
- Live or live attenuated vaccines (in patients receiving immunosuppressive doses of corticosteroids)
- Systemic fungal infections (unless used as replacement therapy)
Major Interactions
- CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, clarithromycin, grapefruit juice) - may increase hydrocortisone levels and effects.
- CYP3A4 inducers (e.g., rifampin, phenytoin, carbamazepine, barbiturates) - may decrease hydrocortisone levels and effects.
- NSAIDs (e.g., ibuprofen, naproxen) - increased risk of gastrointestinal ulceration and bleeding.
- Anticoagulants (e.g., warfarin) - corticosteroids may alter anticoagulant effects (either increase or decrease).
- Diuretics (e.g., thiazides, loop diuretics) - increased risk of hypokalemia.
- Digitalis glycosides (e.g., digoxin) - increased risk of digitalis toxicity due to hypokalemia.
- Antidiabetic agents (e.g., insulin, oral hypoglycemics) - corticosteroids may increase blood glucose, requiring dose adjustments of antidiabetics.
Moderate Interactions
- Cholestyramine, colestipol - may decrease absorption of hydrocortisone.
- Oral contraceptives/estrogens - may increase hydrocortisone levels by increasing transcortin.
- Immunosuppressants (e.g., cyclosporine) - increased risk of seizures with concomitant use; increased levels of both drugs.
- Vaccines (other than live) - diminished antibody response.
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To establish baseline and monitor for mineralocorticoid effects (sodium retention, potassium excretion).
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor for glucocorticoid-induced hyperglycemia.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor for hypertension.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline and monitor for fluid retention.
Timing: Prior to initiation of therapy.
Rationale: If used for adrenal insufficiency, to confirm diagnosis. If used for other conditions, to assess baseline adrenal axis function if prolonged therapy is anticipated.
Timing: Prior to initiation of therapy (especially for adrenal insufficiency).
Routine Monitoring
Frequency: Periodically, especially during initiation or dose changes, or with concomitant diuretics.
Target: Within normal limits (Na: 135-145 mEq/L, K: 3.5-5.0 mEq/L)
Action Threshold: Significant deviations (e.g., K < 3.0 mEq/L or Na > 145 mEq/L) warrant intervention.
Frequency: Periodically, more frequently in diabetic patients or those at risk.
Target: Fasting: <100 mg/dL; Postprandial: <140 mg/dL
Action Threshold: Persistent hyperglycemia (>126 mg/dL fasting) warrants intervention (e.g., diet, antidiabetic medication).
Frequency: Regularly, especially during initiation or dose changes.
Target: <120/80 mmHg
Action Threshold: Sustained hypertension (>140/90 mmHg) warrants intervention.
Frequency: Regularly.
Target: Stable
Action Threshold: Significant weight gain (>2 kg/week) may indicate fluid retention.
Frequency: Regularly (e.g., every 3-6 months) for long-term therapy.
Target: Normal growth velocity for age.
Action Threshold: Growth suppression warrants re-evaluation of therapy.
Frequency: Baseline and periodically (e.g., every 1-2 years) for long-term therapy (>3 months).
Target: Stable or improving BMD.
Action Threshold: Significant bone loss warrants intervention (e.g., calcium, vitamin D, bisphosphonates).
Frequency: Annually for long-term therapy.
Target: Normal intraocular pressure, absence of posterior subcapsular cataracts.
Action Threshold: Elevated IOP or cataract formation warrants ophthalmology referral.
Symptom Monitoring
- Signs of infection (fever, sore throat, malaise, localized pain/redness)
- Gastrointestinal symptoms (abdominal pain, black/tarry stools, vomiting blood)
- Mood changes (depression, euphoria, insomnia, irritability)
- Muscle weakness or pain
- Swelling of ankles/feet
- Unusual bruising or skin thinning
- Vision changes
- Increased thirst or urination
- Signs of adrenal insufficiency upon withdrawal (fatigue, weakness, nausea, vomiting, dizziness, hypotension)
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. Infants born to mothers who have received substantial doses of corticosteroids during pregnancy should be carefully observed for signs of hypoadrenalism.
Trimester-Specific Risks:
Lactation
Hydrocortisone is excreted in breast milk in small amounts. Generally considered compatible with breastfeeding, especially at typical replacement doses. Monitor infant for signs of adrenal suppression (e.g., poor weight gain, irritability) or other adverse effects.
Pediatric Use
Corticosteroids can cause growth retardation in children. Growth should be carefully monitored. Long-term use can also lead to adrenal suppression, osteoporosis, and cataracts. Use the lowest effective dose for the shortest possible duration.
Geriatric Use
Elderly patients may be at increased risk of adverse effects, including osteoporosis, fluid retention, hypertension, and diabetes. Use with caution and monitor closely.
Clinical Information
Clinical Pearls
- Hydrocortisone is the physiological glucocorticoid, making it the preferred agent for adrenal insufficiency replacement therapy.
- For replacement therapy, mimic the body's natural diurnal rhythm by giving a larger dose in the morning and a smaller dose in the afternoon/evening.
- Patients on long-term systemic corticosteroids should never stop the medication abruptly due to the risk of acute adrenal crisis.
- Stress dosing (increasing the dose during illness, surgery, or severe stress) is crucial for patients on chronic hydrocortisone therapy for adrenal insufficiency.
- Monitor for signs of infection, as corticosteroids can mask symptoms and increase susceptibility.
- Consider bone protection strategies (calcium, vitamin D, bisphosphonates) for patients on long-term corticosteroid therapy.
Alternative Therapies
- Prednisone (longer-acting glucocorticoid)
- Methylprednisolone (longer-acting glucocorticoid)
- Dexamethasone (very long-acting, potent glucocorticoid)
- Budesonide (topical or locally acting glucocorticoid with high first-pass metabolism, less systemic effects)
