What is the maximum amount of codeine allowed in a Schedule V preparation?

The maximum amount of codeine allowed in a Schedule V preparation is indeed 200 mg per 100 ml. This regulation is consistent with federal guidelines as well as Massachusetts state laws. Schedule V substances are defined as having a lower potential for abuse compared to those in Schedules I-IV, and they are generally accepted for medical use. The stipulation of 200 mg per 100 ml serves to classify certain formulations containing codeine as permissible for over-the-counter sales under certain conditions, provided they meet this specific threshold. This regulation is in place to ensure safety and mitigate the risk of abuse while still allowing patients access to effective therapeutic options for situations such as cough relief.
