  • Serious cases of gastrointestinal obstruction, ileus, and fecal impaction have been associated with lanthanum use, some requiring surgery or hospitalization. Risk factors include altered gastrointestinal anatomy, hypomotility disorders, and concomitant medications.
  • Instruct patients to chew or crush the tablet completely to reduce the risk of serious adverse gastrointestinal events. Advise patients with poor dentition that they may crush tablets completely. Advise patients to take FOSRENOL with or immediately after meals.
  • Patients with acute peptic ulcer, ulcerative colitis, Crohn’s disease, or bowel obstruction were not included in FOSRENOL clinical studies.
  • FOSRENOL has radio-opaque properties and may give the appearance typical of an imaging agent during abdominal X-ray procedures.
  • The most common adverse reactions seen with FOSRENOL in clinical trials included nausea, vomiting, diarrhea, and abdominal pain.
  • There is potential for FOSRENOL to interact with:
    • compounds that bind to cationic antacids (ie, aluminum-, magnesium-, or calcium-based)
    • oral quinolone antibiotics

These concomitant medications should be dosed separately from FOSRENOL to avoid drug interactions. See the Full Prescribing Information for dosing recommendations.
