If you have nerve problems in your eye, as this may affect your treatment.
Additionally, it is crucial to discuss all of your medications, including:
Prescription and over-the-counter (OTC) drugs
Natural products
Vitamins
with your doctor and pharmacist to ensure safe use. This is not an exhaustive list of potential interactions, and you must verify that it is safe to take this medication with all of your other medications and health conditions. Never start, stop, or change the dose of any medication without first consulting your doctor.
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 discuss this with your doctor. Additionally, prolonged use may lead to weak bones (osteoporosis), so talk to your doctor about your individual risk factors and any concerns you may have.
You may need to reduce your salt intake and take potassium supplements, so consult with your doctor about making these changes. If you have diabetes, it is crucial to closely monitor your blood sugar levels while taking this medication. Before consuming alcohol, discuss the potential risks with your doctor. If you regularly drink grapefruit juice or eat grapefruit, inform your doctor, as this may interact with the medication.
Do not exceed the prescribed dose, as taking more than recommended may increase the risk of severe side effects. Before receiving any vaccinations, 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, notify your doctor immediately.
Steroid medications, including this one, can increase the risk of infection, which can be mild or severe, and even life-threatening. The risk of infection is higher with higher doses of steroids. To minimize this risk, wash your hands frequently, avoid close contact with people who have infections, colds, or flu, and notify your doctor if you experience any signs of infection.
In some cases, this medication can reactivate latent infections, such as tuberculosis or hepatitis B. Inform your doctor if you have a history of these conditions. This medication may also lower the levels of natural steroids in your body, so if you experience a fever, infection, surgery, or injury, consult with your doctor, as you may need additional oral steroids to help your body cope with these stresses. Carry a warning card indicating that you may require extra steroids in certain situations.
If you have been taking this medication for an extended period, do not stop suddenly without consulting your doctor, as this may lead to withdrawal symptoms. If you experience fatigue, weakness, shakiness, rapid heartbeat, confusion, sweating, or dizziness after missing a dose or stopping the medication, notify your doctor promptly.
Long-term use of this medication has been associated with an increased risk of Kaposi's sarcoma, a type of cancer. Discuss this risk with your doctor. If you have or may have a condition called pheochromocytoma, 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 a 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 may 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 has been associated with a specific heart problem in this population.
If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the potential benefits and risks of this medication with your doctor. If you took this medication during pregnancy, inform your baby's doctor. If you have poor adrenal function, be aware that 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. Consult with your doctor if you have any questions or concerns.

Special Patient Groups
Pregnancy
Hydrocortisone is Pregnancy Category C. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal studies have shown adverse effects, but there are no adequate and well-controlled studies in pregnant women. 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. Low doses are generally considered compatible with breastfeeding, but caution is advised. High doses or prolonged use may cause adverse effects in the infant (e.g., growth suppression, interference with endogenous corticosteroid production). Monitor the infant for signs of adrenal suppression.
Pediatric Use
Corticosteroids can cause growth retardation in children. Growth and development should be carefully monitored. Long-term use can also lead to adrenal suppression, requiring careful tapering. Pediatric patients may be more susceptible to adverse effects such as intracranial hypertension.
Geriatric Use
Elderly patients may be at increased risk for adverse effects such as osteoporosis, fluid retention, hypertension, and diabetes. Use the lowest effective dose for the shortest duration possible. Monitor closely for side effects.
Clinical Information
Clinical Pearls
- Always taper corticosteroids gradually when discontinuing, especially after prolonged use, to prevent adrenal insufficiency crisis.
- Administer hydrocortisone in divided doses, mimicking the body's natural diurnal rhythm (e.g., 2/3 in the morning, 1/3 in the afternoon) for adrenal insufficiency.
- Patients on long-term corticosteroids should be advised to carry a steroid card or wear medical alert identification.
- Corticosteroids can mask signs of infection; monitor patients closely for any new symptoms.
- Consider bone protection (calcium, vitamin D, bisphosphonates) for patients on long-term corticosteroid therapy.
- Patients should be educated on potential mood changes and report severe symptoms to their healthcare provider.
Alternative Therapies
- Prednisone (oral)
- Methylprednisolone (oral)
- Dexamethasone (oral)
- Other systemic corticosteroids depending on indication and potency requirements.
