Other than your episode of passing out, what other type symptoms did you have? Most Hymenoptera/Vespid stings obviously produce a local reaction that is nonallergy. ie wheal formation, pain, irritation, itching, and redness and sx generally resolve within a few hours. If the sting is in the right spot ie mouth/throat the local edema could cause serious complications, but this type response is not IgE mediated and thus not anaphylaxis. True anaphylaxis does occur in some individuals after hymenoptera stings. Citing PoisonDex risk factors for development of true allergy may be a short interval

Citing MicroMedex, Dopamine rate should be titrated to desired renal or hemodynamic effect in 2-5mcg/kg/min increases at first then 5-10mcg/kg/min increase. Typical rate is 20-50 mcg/kg/min, while rates greater than 50 mcg/kg/min have been safely used in severe circulatory deficiencies. However rates this high have caused renal dysfunction and rate should be reduced if urine flow decreases without adequate peripheral effects.
