Other key benefits of RELiZORB

  • RELiZORB is still the only FDA-cleared enzyme product that breaks down fats in enteral formula1,2
  • The cartridge is ENFit® compatible and connects directly to enteral-feeding tubes and supplies1
  • Contains iLipase®, the digestive enzyme lipase attached to small microbead carriers, which breaks down fats in enteral formulas as they pass through the cartridge, delivering absorbable fats to your patient’s body. The iLipase remains in the cartridge and is not ingested1
  • Available through specialty pharmacies. For any questions about ordering or receiving RELiZORB, please contact RELiZORB Support Services at 1-844-632-9271 or email [email protected]

RELiZORB is indicated for use in pediatric patients (ages 1 year and above) and adult patients to hydrolyze fats in enteral formula.

Warnings
  • RELiZORB is for use with enteral feeding only.
  • RELiZORB should not be connected to any intravenous (IV) line, setup, or system.
  • Medications should not be administered through the RELiZORB cartridge. Do not add medications to the enteral formula or tubing before RELiZORB. The passage of medications through RELiZORB may adversely affect the medications or the ability of RELiZORB to hydrolyze fats.
  • Fibrosing Colonopathy - Fibrosing colonopathy is a rare, serious adverse reaction associated with high-dose use of pancreatic enzyme replacement therapy in the treatment of patients with cystic fibrosis. The underlying mechanism of fibrosing colonopathy remains unknown. Patients with fibrosing colonopathy should be closely monitored because some patients may be at risk of progressing to stricture formation. RELiZORB contains lipase enzyme that is not from a porcine source. The lipase is bound to the beads, and this lipase-bead complex (iLipase) is retained within the RELiZORB cartridge. Continue to follow your physician’s guidance and porcine pancreatic enzyme labeling regarding porcine pancreatic enzyme use when used in conjunction with RELiZORB.
Cautions and Precautions
  • Do not re-use RELiZORB. RELiZORB is a single-use product. Re-use may result in contamination of the product. If re-used, RELiZORB may not effectively hydrolyze fats.
  • Do not break, alter, or place excess pressure on any part of RELiZORB. Any compromise of the structural integrity of RELiZORB may lead to improper connection to enteral feeding supplies, enteral formula leakage or risk of contamination.
  • Do not use RELiZORB after the date marked on the pouch.
  • Do not use blenderized formulas with RELiZORB. A detailed listing of enteral formulas compatible with RELiZORB can be found at www.relizorbhcp.com/compatibility.
  • RELiZORB is designed for use with enteral feeding pump systems with low flow/no flow alarms and enteral syringes for manual bolus by syringe (push or gravity). A detailed listing of formulas, pumps, and enteral feeding supplies compatible with RELiZORB can be found at www.relizorbhcp.com/compatibility.
  • Do not use excessive force when using RELiZORB with enteral syringe push feeding methods.
  • Do not rush bolus feeds. Follow guidance from your healthcare professional on how long it should take you to complete your tube feeding.
  • Ensure all inlet and outlet connectors on RELiZORB and enteral feeding supplies are clean and dry prior to making connections.
  • In order to ensure product performance, store RELiZORB in its pouch either refrigerated or at room temperature (2°C to 27°C; 36°F to 80°F).
  • RELiZORB is indicated for use with enteral feeding only; patients should follow physician’s guidance for pancreatic enzyme replacement therapy (PERT) use for meals and snacks. Patients and patient caregivers should follow physician’s guidance regarding the need for pancreatic enzyme replacement therapy (PERT) during enteral feeding.
