Question
A client is prescribed sucralfate 1 g PO QID and ciprofloxacin 500 mg PO BID. Which administration schedule should the nurse implement?
1Give both medications at the same time with meals
2Give sucralfate only when symptoms occur
3Give sucralfate on an empty stomach 1 hour before meals and bedtime; separate ciprofloxacin by at least 2 hours from sucralfate to prevent binding✓ Correct answer
4Crush sucralfate and mix with ciprofloxacin syrup
Explanation
Correct (2): Sucralfate is taken on an empty stomach 1 hour before meals and at bedtime to form a protective barrier over the ulcer. It binds many drugs (fluoroquinolones, levothyroxine, phenytoin, digoxin, warfarin) → separate by ≥2 hours. (1) Binding reduces both efficacy. (3) Crushing is unnecessary. (4) Scheduled, not PRN.
In-depth explanation
Memory Tip Sucralfate = "Suck-up-the-acid, separate 2 hours from other drugs." Also causes constipation (aluminum content).
Clinical scenario
Scenario 50-year-old male with duodenal ulcer on sucralfate 1 g PO QID + ciprofloxacin 500 mg PO BID for cellulitis. Discussion at medication reconciliation.
Key concepts
Sucralfate — Aluminum sucrose octasulfate; forms gel barrier over ulcers; binds many drugs.
Empty stomach administration — 1 hour before meals and HS to maximize ulcer surface coverage.
Drug binding separation — At least 2 hours separation from interacting drugs (fluoroquinolones, levothyroxine).
