How many dosage units of opium can be dispensed without a prescription?

The correct answer reflects the legal parameters regarding the sale of opium-containing products without a prescription in Iowa. Under Iowa law, specific over-the-counter medications that contain opium may be sold, but they are limited in quantity to ensure responsible use and to mitigate the potential for abuse.

Iowa law permits the sale of up to 48 dosage units of opium without a prescription. This limit is in place to balance access for legitimate medical use against the risks of misuse and addiction associated with opium products. The designation of 48 dosage units aligns with state statutory guidelines, which aim to regulate how much of these potentially harmful substances can be available to consumers without a healthcare provider's oversight.

In contrast, the other quantity options reflect amounts that exceed the legal limit for dispensing opium without a prescription, making them invalid choices under current regulations. Understanding these limits is crucial for pharmacy practice in Iowa, as it directly impacts how pharmacists dispense controlled substances and ensures compliance with both state and federal laws.
