Should medications be identified by cap and bottle colors and sizes?

• A. Yes
• B. Sometimes
• C. No
• D. Only with a label

Answer: (C)

Medication identification must rely on the label and verified identifiers, not on appearance. Cap color and bottle size can vary between manufacturers, change over time, and there are many look-alike drugs that can be confused by sight alone. The safe approach is to confirm the exact drug by reading its label, noting the name, strength, route, and expiration, and cross-checking with the clinician’s order and the patient. This use of the label fits with the established practice of applying the five rights of medication administration, reducing the risk of giving the wrong drug or dose and preventing adverse events during oral sedation monitoring. If the label is missing or unreadable, do not use the medication. Relying on color or size alone is unsafe, which is why identifying medications by label is the correct approach.
