What is an appropriate topical steroid, dosage, and treatment duration for a 5-year-old child weighing 22.6kg with contact dermatitis to the face suspected to be caused by poison ivy?

From the Guidelines

For a 5-year-old child weighing 22.6kg with facial contact dermatitis from suspected poison ivy, I recommend using hydrocortisone 1% cream, a mild (low-potency) topical steroid, applied thinly twice daily for 5-7 days. The face requires a milder steroid due to thinner skin that absorbs medication more readily, increasing the risk of side effects. Limit application to affected areas only, avoiding the eyes, mouth, and any open wounds. After applying the medication, wash hands thoroughly to prevent spread to other body areas or eyes. If symptoms worsen or don't improve within 3-5 days, medical evaluation is needed. Complement steroid treatment with cool compresses to reduce itching and inflammation, and ensure the child avoids scratching to prevent secondary infection. This approach balances effective symptom relief while minimizing risks of skin thinning, pigmentation changes, or systemic absorption that can occur with stronger steroids or prolonged use on facial skin, as suggested by the 2024 American Heart Association and American Red Cross guidelines for first aid 1. Additionally, washing the exposed area with soap and water as soon as possible after exposure can help remove up to 100% of poison ivy oils if done immediately, as noted in the same guidelines 1. It's also important to consider that the usefulness of over-the-counter topical steroids to alleviate local symptoms from poison ivy is uncertain, as stated in the guidelines 1, but given the mild nature of hydrocortisone 1% cream, it is a reasonable choice for initial treatment. The treatment should be monitored, and if there's no improvement, further evaluation may be necessary to rule out other conditions such as allergic contact dermatitis, which can be a consideration in cases of dermatitis, as discussed in guidelines for the management of atopic dermatitis 1. However, for poison ivy, the primary approach remains removal of the offending agent and symptomatic relief. Given the potential for allergic contact dermatitis, it's crucial to be aware of the common allergens and the role of patch testing in diagnosis, as outlined in the guidelines for the diagnosis and management of pediatric atopic dermatitis 1, though this is more relevant for chronic conditions rather than acute poison ivy exposure. The key takeaway is to use the mildest effective steroid, for the shortest necessary duration, to minimize side effects while providing relief, as generally recommended for topical corticosteroid use in sensitive areas like the face 1.

From the FDA Drug Label

DOSAGE & ADMINISTRATION Topical corticosteroids are generally applied to the affected area as a thin film from two to three times daily depending on the severity of the condition. PEDIATRIC USE Pediatric patients may demonstrate greater susceptibility to topical corticosteroid-induced HPA axis suppressionand Cushing's syndrome than mature patients because of a larger skin surface area to body weight ratio

For a 5-year-old child weighing 22.6kg with contact dermatitis to the face suspected to be caused by poison ivy, triamcinolone acetonide could be considered as a topical steroid.

• The dosage would be a thin film applied to the affected area 2-3 times daily.
• Given the potential for HPA axis suppression and other systemic effects, especially in children, treatment duration should be limited to the minimum amount compatible with an effective therapeutic regimen.
• It is crucial to monitor for signs of adrenal suppression, Cushing's syndrome, and intracranial hypertension.
• The use of topical corticosteroids in children should be under close supervision, and chronic use should be avoided to prevent interference with growth and development 2 2.

From the Research

Topical Steroid for Contact Dermatitis

• For a 5-year-old child with contact dermatitis to the face suspected to be caused by poison ivy, a mild to moderate potency topical steroid may be considered, such as hydrocortisone or triamcinolone acetonide 3.
• However, it is essential to note that the use of topical corticosteroids in irritant contact dermatitis, such as poison ivy, is controversial, and their efficacy is not well established 4.

Dosage and Treatment Duration

• The dosage and treatment duration of topical steroids for children should be determined based on the child's weight and the severity of the condition.
• For a 5-year-old child weighing 22.6kg, the dosage of hydrocortisone or triamcinolone acetonide should be calculated based on the recommended dosage for children, which is typically 0.5-1% of the total body surface area affected, applied 2-3 times a day 3.
• The treatment duration should be limited to the shortest duration necessary to control the symptoms, typically 5-7 days, to minimize the risk of side effects and rebound phenomenon 4.

Considerations for Children

• When using topical steroids in children, it is crucial to consider their age, weight, and the potential for side effects, such as skin atrophy, telangiectasia, and adrenal suppression 3.
• The child's growth and development should also be monitored, using growth charts and standards, such as those provided by the World Health Organization (WHO) for children 0-5 years 5 or the Indian Academy of Pediatrics for 5-18-year-old children 6.
