When counting and preparing prescriptions for which type of products must they be counted on separate trays to minimize contamination risks?

When preparing prescriptions, certain products require specific handling procedures to ensure safety and minimize contamination risks. Herbal products should be counted on separate trays because they often have loose particulate matter or oils that can contaminate other medications. Moreover, herbal products may not be subject to the same purity standards as prescription medications and over-the-counter items, potentially introducing additional contaminants if mixed with pharmaceuticals.

Using separate trays for these products reduces cross-contamination, ensuring that each medication remains pure and effective. This practice is vital, especially in a pharmacy setting, where the safety of the patient is paramount. Other products like over-the-counter and prescription medications generally have standardized preparation processes, while injectables require a sterile environment, making them inherently distinguishable in preparation requirements. However, herbal products stand out due to their unique characteristics and the need for precautionary steps in handling.
