The maximum dosage of a specific anesthetic is pivotal primarily to prevent systemic toxicity. Anesthetics can have significant effects on the cardiovascular and central nervous systems, and exceeding the recommended dosages can lead to serious complications such as seizures, cardiovascular collapse, respiratory depression, and other toxic effects. Maintaining the dosage within safe limits helps safeguard the patient’s overall well-being and ensures that the administration of anesthesia is both safe and effective.

While patient comfort is essential, it is typically managed within the bounds of safe dosing. Local swelling might occur due to various factors but isn't a direct consideration tied to the maximum dosage in the context of safety. Enhancing anesthetic effectiveness is important, yet it must always be balanced with the necessity of preventing toxicity. Thus, the priority lies in ensuring the patient is safe from adverse systemic reactions when using anesthetics.
