From the Guidelines
The initial treatment approach for a pediatric patient presenting with a rash should begin with a thorough assessment to identify the cause, and for mild, non-specific rashes, gentle skin care is recommended, including using mild, fragrance-free soaps, applying moisturizers, and avoiding potential irritants, as suggested by the most recent guidelines 1.
Key Considerations
- For itchy rashes, over-the-counter 1% hydrocortisone cream can be applied sparingly twice daily for up to 7 days, along with oral antihistamines like diphenhydramine (Benadryl) at 1-2 mg/kg/dose every 6 hours as needed (maximum 50 mg per dose) or cetirizine at age-appropriate dosing (2.5-5 mg daily for ages 2-5-10 mg daily for ages 6+), as per standard treatment protocols.
- Cool compresses and oatmeal baths can provide symptomatic relief for itchy rashes.
- For suspected bacterial infections presenting with pustules, crusting, or weeping, topical antibiotics like mupirocin applied three times daily for 7-10 days may be appropriate, based on clinical judgment and guidelines for managing skin infections.
Specific Conditions
- For pediatric patients with psoriasis, guidelines suggest the use of topical corticosteroids, vitamin D analogues, and biologics in certain cases, as outlined in the joint American Academy of Dermatology-National Psoriasis Foundation guidelines 1.
- In cases of suspected drug allergy, such as a reaction to amoxicillin, a direct penicillin challenge without preceding skin tests may be recommended for pediatric patients with a history of benign cutaneous reactions, according to the 2022 practice parameter update on drug allergy 1.
Monitoring and Follow-Up
- It's essential to monitor for signs of systemic illness such as fever, lethargy, or spreading redness, which warrant immediate medical attention.
- The treatment approach should be tailored based on the specific diagnosis, as different rashes (viral exanthems, allergic reactions, eczema, etc.) require different management strategies, emphasizing the need for accurate diagnosis and personalized care.

- For children 2 years of age and older, hydrocortisone can be applied to the affected area not more than 3 to 4 times daily.
- For children under 2 years of age and children under 12 years of age, it is recommended to ask a doctor for guidance on treatment 2.
From the Research
Initial Treatment Approach
The initial treatment approach for a pediatric patient presenting with a rash depends on the underlying cause of the rash.
- For impetigo, a common bacterial skin infection in children, treatment includes topical antibiotics such as mupirocin, retapamulin, and fusidic acid 3.
- For atopic dermatitis, irritant avoidance and liberal emollient usage are recommended as the cornerstone of treatment, with topical corticosteroids as first-line medication-based therapy 4.
- A thorough history and physical examination are essential to assess and solidify an appropriate diagnosis, and choose an appropriate treatment 5.
Diagnostic Considerations
When evaluating a pediatric patient with a rash, it is essential to consider the following:
- The presence of fever, which can indicate an infectious or non-infectious etiology 5.
- The characteristics of the rash, such as its appearance, location, and duration 6.
- The patient's medical history, including any allergies or previous illnesses 7.
Treatment Options
Treatment options for pediatric patients with a rash depend on the underlying cause, but may include:
