Final answer:
The repeat dose of lidocaine varies based on medical context and must be determined according to specific guidelines or a healthcare professional's advice.
Step-by-step explanation:
The question 'What is the repeat dose of lidocaine?' pertains to the administration of a medication in a medical context. However, the reference information provided discusses the treatment regimen of benzathine benzylpenicillin for prophylaxis against infections, which is not related to lidocaine. As such, this specific question about the repeat dose of lidocaine should be answered with regard to standard medical guidelines for lidocaine dosage. Unfortunately, due to the lack of specific details regarding the use-case (such as local anesthesia, antiarrhythmic therapy, etc.), the exact repeat dose of lidocaine cannot be provided. The dosing of lidocaine varies depending on the indication, route of administration, patient weight, and health condition. For accurate dosing, it is essential to consult standard medical resources or a healthcare professional.
