What type of packaging is required for OTC drugs to prevent adulteration?

Tamper-resistant packaging is important for over-the-counter (OTC) drugs as it helps to ensure the safety and integrity of the product. This type of packaging features methods that indicate whether a product has been tampered with, thereby providing a safeguard against potential contamination or adulteration. The FDA has specific regulations that require OTC medications to be packaged in a manner that protects against tampering.

Child-resistant packaging, while crucial in preventing accidental ingestion by children, does not specifically address the issue of tampering. Humidity-resistant and light-protective packaging, although useful for preserving the stability of certain medications, do not directly relate to the prevention of adulteration or tampering. Thus, tamper-resistant packaging stands out as the most relevant requirement for protecting OTC drugs from adulteration.
