For a patient with an allergy to red wine, which local anesthetic would be preferred?

• A. Mepivacaine 3% or Prilocaine 4% (no Epinephrine)
• B. Articaine with Epinephrine
• C. Lidocaine with Epinephrine
• D. Bupivacaine with Epinephrine

Answer: (A)

Red wine allergy often signals sensitivity to sulfites, which are used as preservatives in many epinephrine-containing local anesthetic solutions. If a patient has a sulfite sensitivity, exposing them to these preservatives can trigger a reaction. Choosing a local anesthetic without epinephrine avoids this sulfite exposure, making it the safer option for someone with red wine allergy. Among the available choices, using mepivacaine 3% or prilocaine 4% without epinephrine provides effective anesthesia without the sulfite-containing preservative found in epinephrine formulations. The epinephrine-containing options carry the risk of a sulfite reaction, so they are not preferred in this context.
