The pharmacy should write the correct dosing day on both the label and box for which drug?

• A. Rotavirus
• B. Methotrexate
• C. Vitamin A
• D. MMR

Answer: (B)

Labeling the dosing day for a weekly medication is essential to prevent daily-dosing errors. Methotrexate is often prescribed on a once-weekly basis, and missing or misinterpreting that schedule can lead to taking it daily or skipping a dose, both of which can cause life‑threatening toxicity such as bone marrow suppression, liver injury, and severe mucositis. By printing the exact day of the week the drug should be taken on both the bottle label and the outer box, the pharmacy provides a clear, consistent cue across dispensing, counseling, and refills, helping patients adhere to the intended schedule and avoid dangerous mistakes. The other listed items do not carry the same weekly-dosing risk profile; vaccines and vitamins follow different dosing patterns and do not typically require a specific “day” on the label to prevent lethal dosing errors.
