As of my last knowledge update in January 2022, I don’t have specific information on new rules regarding antibiotic doses in the United States. Antibiotic guidelines and regulations may be subject to updates by healthcare authorities, such as the Centers for Disease Control and Prevention (CDC) or the Food and Drug Administration (FDA). It is recommended to consult the latest guidelines from these agencies or other reputable healthcare sources for the most current information on antibiotic dosing regulations in the United States.
