Why is adrenaline not IV for anaphylaxis?

IM injection is also preferred over intravenous (IV) bolus because it is faster in many situations and safer (ie, lower risk of cardiovascular complications, such as severe hypertension and ventricular arrhythmias). The epinephrine dilution for IM injection contains 1 mg/mL.

Which drug is most common with anaphylactic shock?

Drug-induced anaphylaxis can be a life-threatening condition occurring after drug intake by any route, including non-therapeutic exposure due to accidental contact. The most common culprit drugs are non-steroidal anti-inflammatory drugs and beta-lactam antibiotics.
