What is the dispensing limit for any controlled substance without a prescription?

The dispensing limit for any controlled substance without a prescription, particularly in the context of Iowa law, is set at 4 ounces. This limitation is in place to prevent misuse and ensure that controlled substances are dispensed responsibly. The restriction serves to protect public health by regulating the quantity of potentially addictive medications that can be obtained without a formal prescription.

When discussing the other options, it is essential to note that they exceed the maximum amount allowed for a non-prescription dispensation and do not align with the legal framework designated for controlled substances. Maintaining a clear understanding of these limits is crucial for pharmacists and healthcare providers to navigate the laws governing the distribution of controlled substances safely and effectively.
