What is the maximum dosage of lidocaine for healthy adults per appointment?

• A. 300 mg
• B. 400 mg
• C. 600 mg
• D. No specific limit

Answer: (B)

The maximum dosage of lidocaine for healthy adults per appointment is set at 400 mg. This limit is determined based on safety considerations to prevent potential toxicity, as lidocaine is a local anesthetic that works by blocking nerve conduction. Exceeding the recommended dosage could lead to serious side effects, including central nervous system and cardiac complications. In practice, when administering lidocaine, dental professionals carefully calculate the total dosage based on the concentration of the lidocaine solution used and the volume that is being injected. Typical formulations of lidocaine commonly used in dentistry contain 2% concentration, with a common maximum dose being 5 mg/kg for healthy adults. Given that an average healthy adult weighs around 70 kg, this yields the 400 mg maximum allowable limit. While lower maximum dosages exist for specific populations or conditions (such as patients with certain health issues or those who are elderly), for the general healthy adult, the 400 mg limit is a standard guideline to ensure patient safety and efficacy when using local anesthetic agents like lidocaine.
