Question

Quizplus · Accepted Answer

All options listed are appropriate for a patient with a true bisulfite allergy because none of these local anesthetics contain bisulfites. Bisulfites are commonly used as preservatives in some local anesthetic solutions that contain vasoconstrictors like epinephrine, but not all formulations include them. Mepivacaine, prilocaine, and articaine in the specified formulations do not contain bisulfites, making them safe choices for patients with bisulfite allergies.
