Epinephrine (1 mg/ml aqueous solution [1:1000 dilution]) is the first-line treatment for anaphylaxis and should be administered immediately. In adults, administer a 0.3 mg intramuscular dose using a premeasured or prefilled syringe, or an autoinjector, in the mid-outer thigh (through clothing if necessary).

Q: How long does recovery after anaphylactic shock take? A: It may take a few days to fully recover after treatment.
How do you give EPI to anaphylaxis?
Epinephrine 1:1,000 dilution, 0.2 to 0.5 mL (0.2 to 0.5 mg) in adults, or 0.01 mg per kg in children, should be injected subcutaneously or intramuscularly, usually into the upper arm.
