Abstract:
We report 2 cases of hypersensitivity to an epinephrine preparation in local anesthetics which were found by skin tests for local anesthetics. Both patients had uncomfortable episodes to local anesthetics at dental treatment. In both cases, the skin tests showed positive reactions to 2% lidocaine with 1:80,000 epinephrine. Furthermore drug lymphocyte stimulation test revealed positive reaction to epinephrine hydrochloride, epinephrine bitartrate in case 1, whereas in case 2, the drug lymphocyte stimulation test showed positive response to epinephrine bitartrate. Attention should be paid to exogenous epinephrine preparations that have the potential to induce hypersensitivity during dental treatment.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
