Final answer:
Drugs in an emergency drug kit must be clearly labeled with content and dosage, and comply with FDA and other relevant regulations for safety and efficacy.
Step-by-step explanation:
The labeling requirements for drugs stored in an emergency drug kit (EDK) are crucial for ensuring that medications are used safely and effectively. Drugs must be labeled clearly with their contents and dosage information, and comply with various regulations depending on whether they are new drugs, generic drugs, or over-the-counter drugs. New drugs, for instance, go through an extensive FDA review and require a New Drug Application (NDA) before they can be prescribed.
Once approved, they must be labeled as 'safe and effective when used as directed.' All medications, including those in an EDK, must adhere to guidelines issued by the FDA and other relevant agencies such as the EMA or the United States Department of Transportation, which regulate the safe transportation and handling of medication.
