A patient taking ibandronic acid should be told to remain upright for how long after taking?

• A. Lie down immediately
• B. Remain upright for at least 1 hour
• C. Take with fruit juice
• D. Take at bedtime

Answer: (B)

This question tests how to minimize esophageal irritation when taking an oral bisphosphonate. Ibandronic acid can irritate the lining of the esophagus, so the tablet should be taken with a full glass of plain water and the person should remain upright for a period afterward to prevent reflux and help the tablet reach the stomach.

Remaining upright for at least 60 minutes after taking the tablet is the best practice because gravity helps prevent the tablet from lingering in the esophagus, reducing the risk of esophagitis or ulcers. Lying down immediately increases contact time with the esophagus, elevating irritation risk. Taking the medication with fruit juice is not advised since beverages other than water can affect absorption and may irritate the esophagus. Taking it at bedtime would also raise the chance of nighttime reflux, again increasing esophageal exposure. After the 60-minute window, normal activities, meals, and other medications can be resumed.
