What medication is recommended for allergic rash in children under 2 years old?

From the Guidelines

For allergic rashes in children under 2 years old, antihistamines such as diphenhydramine or cetirizine may be prescribed, but only under the guidance of a pediatrician, as there are no recommended preventive medications and treatment should focus on symptom management. When considering medication for allergic rashes in this age group, it's essential to prioritize the management of symptoms while ensuring the safety and appropriateness of the treatment. According to 1, for children presenting with a likely food allergy, which can manifest as an allergic rash, antihistamines can be used for mild symptoms.

Key considerations for managing allergic rashes in children under 2 years old include:

• Consulting a pediatrician before initiating any medication due to the potential for severe reactions and the importance of accurate diagnosis.
• Using antihistamines such as diphenhydramine or cetirizine for mild symptoms, with dosing carefully calculated based on the child's weight, as these medications can help alleviate symptoms by blocking histamine.
• Avoiding the use of antihistamines in place of epinephrine for severe reactions, as epinephrine is crucial for relieving severe symptoms and can be lifesaving, as noted in 1.
• Implementing non-pharmacological measures to soothe the skin and prevent further irritation, such as applying fragrance-free moisturizers, keeping the child's nails short, and dressing them in loose cotton clothing.
• Recognizing the signs of severe reactions, such as diffuse hives, shortness of breath, or circulatory symptoms, and seeking immediate medical attention if these occur, as they may require epinephrine and other adjunctive treatments mentioned in 1.

Medication Options for Allergic Rash in Children Under 2 Years Old

• Topical corticosteroids are recommended as first-line medication-based therapy for infants under 2 years old with allergic rash, as stated in the clinical guidelines article 2.
• Pimecrolimus, a topical calcineurin inhibitor, may also be used in infants as young as 3 months, as mentioned in the same article 2.
• Non-traditional therapies, such as the Aron regime, may be considered as a last resort in patients under 2 years old with refractory or resistant allergic dermatitis, before off-label medications are considered 2.

Safety of Topical Medications in Young Children

• A 36-month follow-up study found that topical tacrolimus (0.03% and 0.1% ointments) and topical corticosteroids (mild and moderate potency) are safe to use in young children with moderate to severe atopic dermatitis, with comparable efficacy and safety profiles 3.
• The study also found that there were no significant differences between the treatment groups for skin-related infections, growth parameters, and vaccination responses 3.

Considerations for Topical Corticosteroid Use

• Allergy or dependence to topical corticosteroids should be considered when a topical corticosteroid fails to control a skin condition, as noted in a review article on topical steroid allergy and dependence 4.
• Contact dermatitis due to a topical corticosteroid can be difficult to diagnose, and risk factors include long-term, frequent application of topical steroids by patients with certain skin conditions 4.
• Cross-reactions to topical corticosteroids can occur, and switching to a second topical corticosteroid may not be effective, as discussed in a review article on allergic contact dermatitis due to topical application of corticosteroids 5.
