For potassium in OTC products, how much per dose must be labeled?

  1. More than 2 mg

  2. More than 5 mg

  3. More than 10 mg

  4. More than 15 mg

The correct answer is: More than 5 mg

The requirement for labeling potassium in over-the-counter products is significant for consumer safety and awareness. Specifically, when potassium is present in a product in a dosage strength that exceeds 5 mg per dose, proper labeling is mandated. This regulation aims to ensure that consumers are adequately informed about the amounts of potassium they are ingesting, as excessive intake can lead to serious health issues, such as hyperkalemia, which can affect heart function. The threshold of 5 mg serves as a clear guideline for manufacturers, prompting them to provide necessary warnings or advisories on the product packaging regarding potassium content. This ensures that individuals, especially those with conditions that affect potassium levels or those who are on certain medications, can make more informed decisions regarding their use of such products.
