What is the dosing for a child less than 1 year and weighing over 5kg requiring Epinephrine for Croup?

For a child less than 1 year of age weighing over 5 kg who requires Epinephrine for the treatment of Croup, the correct dosing is indeed 2.5 mg.

In the context of Croup, which is often characterized by inflammation and narrowing of the upper airway, nebulized Epinephrine is commonly used to rapidly reduce airway swelling and improve breathing. The recommended dose for nebulized racemic Epinephrine in children is typically around 0.05 to 0.1 mL/kg of a 2.25% solution, which translates to approximately 2.5 mg for a child in this weight category.

This dosing is based on both efficacy and safety, ensuring that the child receives enough medication to alleviate symptoms without risking potential adverse effects. Proper dosing is crucial in pediatric emergencies, especially in cases involving airway compromise.
