可能的副作用

• Gastrointestinal upset (nausea, vomiting, diarrhea, or constipation)
• Decreased absorption of fat-soluble vitamins (A, D, E, K) and folic acid

注意事項與禁忌

• Hypophosphatemia
• Bowel obstruction

• > **Pregnancy & Nursing**: Safety during pregnancy is not established (FDA Category C). Because of the potential for binding vitamins, additional vitamins (both fat and water-soluble) may be necessary for pregnant or nursing animals. * **Vitamin K Deficiency**: Because sevelamer can bind fat-soluble vitamins, it may impact Vitamin K absorption, potentially affecting coagulation. * **Administration Timing**: Must be given with meals to be effective at binding dietary phosphorus.

• Ciprofloxacin (and other oral fluoroquinolones): Concurrent administration may decrease absorption by 50%; administer at least 1 hour before or 3 hours after sevelamer.
• Oral Medications (Narrow Therapeutic Index): May reduce absorption; consider dosing other oral drugs separately.
