Drug Interactions
Sucralfate works locally by binding to ulcerated mucosa. Its primary interaction concern is impaired absorption of other oral medications taken simultaneously.
- Fluoroquinolone antibiotics (e.g., ciprofloxacin, levofloxacin, moxifloxacin): Sucralfate chelates fluoroquinolones in the gut and can reduce their absorption by more than 50%. Administer fluoroquinolones at least 2 hours before sucralfate.
- Levothyroxine: Sucralfate significantly impairs levothyroxine absorption, potentially causing hypothyroidism. Separate doses by at least 4 hours and recheck TSH after starting therapy.
- Warfarin: Sucralfate can reduce warfarin absorption and lower INR. Separate administration by at least 2 hours and monitor INR closely.
- Phenytoin, digoxin, tetracyclines, ketoconazole, H2 blockers, fat-soluble vitamins (A, D, E, K): Reduced absorption when taken with sucralfate. Separate administration by at least 2 hours.
- Aluminum-containing antacids: Concurrent use increases the risk of aluminum accumulation, particularly in patients with renal impairment. Avoid combination or use cautiously with monitoring.
- Citrate-containing products (e.g., effervescent calcium, potassium citrate): Increase aluminum absorption from sucralfate. Avoid concurrent use, especially in patients with kidney disease.
