[gotcha] Instructing users to inject an epinephrine auto-injector into the buttocks or vein

Inject firmly into the outer mid-thigh \(vastus lateralis muscle\). Do not inject into the buttocks or any other location.

Journey Context:
Intramuscular epinephrine must go into a large muscle with good blood flow. The thigh is ideal. The buttocks have thick subcutaneous fat layers that can prevent the needle from reaching the muscle, delaying absorption during anaphylaxis, and risk hitting the sciatic nerve. AI might generalize 'injections go in the buttocks' from other medications, which is fatal here.
