PERT Brands: Comparing Your Options

Several FDA-approved pancreatic enzyme replacement products are available. While they all contain the same basic enzymes, there are differences in strengths, formulations, and costs that may influence which works best for you.

Key Insight

All FDA-approved PERT products contain porcine-derived enzymes with similar effectiveness. The main differences are in available strengths, capsule size, coating technology, and cost. Your doctor can help determine which brand suits your specific needs.

Factors to Consider

Cost & Insurance

PERT is expensive without insurance. Check your plan's formulary to see which brands are covered. Patient assistance programs are available from most manufacturers.

Strength Options

Having the right strength options lets you fine-tune your dose. Zenpep offers the widest range, which can be helpful for precise dosing.

Capsule Size

If you have difficulty swallowing, compare capsule sizes. Some brands have smaller capsules for the same strength.

Response & Tolerance

Some patients respond better to one brand than another, even though they're similar. If one doesn't work well, trying a different brand is reasonable.

Important Notes

  • Don't switch brands without consulting your doctor – Doses may need adjustment
  • Generic PERT is not available – All products are brand-name only
  • Pork-derived – All FDA-approved products come from porcine sources
  • Not interchangeable – Pharmacy cannot substitute one brand for another without prescriber approval
