According to federal guidelines, a pharmacist may not sell more than how many dosage units of C5 other than opium in a 48-hour period?

A pharmacist may not sell more than 24 dosage units of Schedule V controlled substances, other than those containing opium, in a 48-hour period according to federal guidelines. This limit is established to prevent potential abuse or diversion of these medications, which, while considered to have a lower potential for abuse compared to higher schedules, can still lead to misuse if not carefully regulated.

The regulation sets this specific limit to ensure that pharmacists monitor the distribution of these substances responsibly. By restricting the quantity a customer can purchase in a short timeframe, it helps to safeguard against circumstances where a person might attempt to accumulate large amounts of a controlled substance for illicit purposes. The requirement aligns with broader efforts to control the distribution of medications that could contribute to substance misuse and dependence.

The other quantities mentioned are not consistent with federal regulations, which specifically state the maximum allowable dosage units a pharmacist can sell in the outlined time frame.
