What is the initial intramuscular dosage of epinephrine for anaphylaxis?

Epinephrine is the first-line treatment for anaphylaxis, given by intramuscular injection to rapidly counter airway swelling, bronchospasm, and low blood pressure. The typical starting dose for most patients is 0.3 mg IM, delivered into the mid-thigh using a 1:1000 concentration. This dose is appropriate for adults and for children who weigh about 30 kg or more. For smaller children, the dose is lower (0.15 mg IM, usually for about 15–30 kg). Higher doses like 0.5 mg or 1 mg are not used as the initial intramuscular dose in standard EMS practice because they increase the risk of adverse effects and aren’t indicated for initial management of anaphylaxis.
