What is a requirement for a written prescription for a controlled substance?

In the context of Florida's regulations for prescriptions of controlled substances, a requirement is that the quantity of the drug prescribed must be indicated both in textual (word) and numerical formats. This dual format is crucial because it helps prevent misinterpretation or errors that could arise from a single format. Using both formats adds an additional layer of security and clarity, ensuring that the amount prescribed is accurately understood.

The inclusion of quantity in both forms is a standard practice aimed at improving patient safety and reducing the risk of medication errors. Properly detailing the quantity in these two ways serves as a safeguard against potential alterations or misunderstandings regarding the prescribed amount.

While other options may contain information relevant to prescription requirements, they do not match the specific emphasis on the quantity format that is vital in avoiding errors in medication dispensing.
