Which epinephrine dose is listed for infants with wheezing?

Epinephrine dosing for infants with wheezing is given intramuscularly using a weight-based approach with a safety cap. The standard guideline is 0.01 mg/kg per dose of a 1:1000 (0.01 mg per kilogram of body weight) solution, with a maximum single dose of 0.3 mg. When you calculate for many infants, that maximum dose is reached, so the listed dose becomes 0.3 mg given IM. This route and dose setup are chosen because IM epinephrine acts quickly to relieve airway edema and bronchodilate, which is crucial in a wheezing infant. Intravenous epinephrine is not used in this scenario unless in a setting of life-threatening shock or cardiac arrest and requires close monitoring. Inhaled (nebulized) epinephrine is more typical for airway conditions like croup rather than systemic wheezing from asthma or anaphylaxis. The 0.15 mg option would be a smaller, weight-based dose in some cases, but the standard listed single-dose maximum for this context is 0.3 mg IM.
