Medications labeled XR should be taken ...

• A. Only with food
• B. At bedtime
• C. Same time each day
• D. Twice daily

Answer: (C)

XR medications are extended-release formulations that release the drug slowly to keep blood levels steadier over time. Taking them at the same time each day helps maintain a consistent therapeutic level and prevents gaps or spikes that could occur with irregular dosing. This consistency matches the designed release pattern, often supporting once-daily dosing. The other options aren’t universally true: meals can affect some drugs but timing consistency is the key goal; taking at bedtime isn’t required by the XR design; and taking XR twice daily is less aligned with the purpose of extended release unless a specific product is indicated for that schedule.
