Hydrocortisone is a type of corticosteroid that reduces inflammation and suppresses the immune system. It is used in pediatric medicine for a variety of conditions, from skin rashes like eczema to systemic issues caused by adrenal insufficiency or chronic inflammatory diseases. While effective, its use in children, particularly long-term, requires careful consideration of the potential side effects.
Systemic Side Effects
Systemic hydrocortisone refers to medication taken orally or via injection, where it circulates throughout the body. The side effects are often dose- and duration-dependent, meaning higher doses and longer courses of treatment carry a greater risk.
Common Short-Term Systemic Effects
Even with short courses of treatment (less than 14 days), children can experience notable side effects.
- Mood and behavioral changes: Irritability, restlessness, hyperactivity, anxiety, and sleep disturbances are frequently reported.
- Increased appetite and weight gain: This can occur quickly due to changes in metabolism.
- Nausea and stomach upset: Vomiting can sometimes occur, particularly with higher doses.
- Increased blood sugar: Blood sugar levels can temporarily rise, especially concerning for children with diabetes.
Significant Long-Term Systemic Effects
Chronic use of hydrocortisone over many weeks or months can lead to more serious and lasting health issues.
- Growth suppression: This is a major concern unique to the pediatric population. Corticosteroids can inhibit the body's natural growth hormone and reduce bone formation, potentially affecting a child's final adult height. Regular growth monitoring is essential during treatment.
- Adrenal gland suppression: The body's adrenal glands may produce less of their own steroids when an external source is provided. This can lead to a potentially fatal adrenal crisis if the medication is stopped abruptly. The dose must be tapered gradually under a doctor's supervision.
- Cushing's syndrome: Prolonged, high-dose use can cause symptoms resembling Cushing's syndrome, including a rounded, puffy "moon face," fat buildup on the upper back and abdomen, and high blood pressure.
- Weakened immune system: Hydrocortisone's immunosuppressive effects increase a child's risk of developing serious infections, including potentially deadly ones like varicella (chickenpox).
- Osteoporosis: Long-term use can weaken bones, increasing the risk of fractures. This is a particular risk for children whose bones are still developing.
Topical Hydrocortisone Side Effects
Topical hydrocortisone, used for inflammatory skin conditions like eczema, generally has fewer and less severe side effects than systemic use. However, systemic absorption can still occur, especially in infants with more permeable skin, or when used over large areas or under occlusive dressings (like tight diapers).
Localized Skin Reactions
- Skin thinning: Prolonged or high-strength topical use can cause the skin to become thin, fragile, and easily bruised.
- Skin color changes: Lighter or darker patches may appear on the skin.
- Increased hair growth: Unwanted hair growth can occur in the treated areas.
- Irritation: A burning, stinging, or itching sensation is common at the application site.
Systemic Absorption Risks
As noted, infants and young children are particularly susceptible to systemic side effects from topical application. The National Eczema Association notes that excessive exposure has been linked to slowed growth and delayed weight gain in children. Iatrogenic Cushing's syndrome from potent topical steroid use has also been documented in infants.
Comparing Topical vs. Systemic Hydrocortisone Side Effects in Children
To provide a clear understanding of the different risks, here is a comparison table:
Side Effect | Topical Hydrocortisone | Systemic Hydrocortisone (Oral/Injection) |
---|---|---|
Growth Suppression | Possible, especially with high-potency use over large areas in infants. | Significant risk with long-term, high-dose use. |
Adrenal Suppression | Possible, especially in young children with overuse. | High risk with prolonged use; requires gradual tapering. |
Cushing's Syndrome | Rare, but documented in infants with potent topical steroids. | Common with high doses and long-term use. |
Immunosuppression | Increased risk of localized skin infections. | Increased risk of serious systemic infections. |
Skin Changes | Common (thinning, discoloration) at application site. | Can cause acne and fragile, thin skin generally. |
Mood & Behavioral Changes | Less likely, but possible with significant systemic absorption. | Common, even with short-term use (irritability, anxiety, hyperactivity). |
Metabolic Effects | Minimal unless systemic absorption is significant. | Common (weight gain, increased blood sugar). |
Managing Hydrocortisone in Children
To minimize risks, it is crucial to follow a doctor's instructions meticulously:
- Use the lowest effective dose for the shortest duration. For topical use, this might mean applying a thin layer less frequently.
- Avoid overuse, especially on sensitive areas. Do not apply potent topical formulations to the face, groin, or underarms unless specifically directed by a doctor.
- Use correct application techniques. For topical medication, avoid occlusive dressings on infants unless instructed, as this increases absorption.
- Do not stop systemic medication abruptly. Tapering must be managed by a doctor to prevent adrenal crisis.
- Monitor for side effects. Parents should be vigilant for changes in mood, behavior, appetite, and any signs of infection. Regular checkups are necessary for children on long-term systemic therapy.
Conclusion
While hydrocortisone is a valuable treatment for many childhood conditions, its use comes with a range of potential side effects that must be carefully managed. The severity and type of side effects are highly dependent on the medication's form, dose, and duration of use. Parents and caregivers should work closely with their child's healthcare provider to ensure that the medication is used safely and effectively, minimizing the risks while maximizing the therapeutic benefits. Open communication and regular monitoring are essential components of care when hydrocortisone is part of a child's treatment plan.
