Biologic vs. Biosimilar: Which Is Right for You?
FDA-approved effectiveness, but different savings programs — here's how to decide
Key Takeaways
- Biosimilars are FDA-approved and equally effective as the reference biologic
- The best choice depends on your insurance formulary and available savings programs
- Sometimes the original biologic is cheaper due to a stronger copay program
- BiologicHealthPlus will compare both options for your specific insurance plan
Clinical Differences: There Are None
From a clinical standpoint, an FDA-approved biosimilar is equivalent to the reference biologic. The FDA approval pathway requires demonstration of no clinically meaningful differences in safety, purity, and potency. Real-world evidence and clinical trials support that biosimilars perform identically to reference biologics for approved indications.
When the Original Biologic May Be Cheaper
This surprises many patients: sometimes the original brand-name biologic is cheaper than its biosimilar — because the original manufacturer's copay program is more generous. For example, some Humira biosimilars have less robust savings programs than myAbbVie Assist, leaving commercially insured patients paying more out of pocket.
When a Biosimilar May Be Cheaper
If your insurance plan has placed the reference biologic on a higher formulary tier but the biosimilar on a lower tier — or if you are uninsured and paying cash — a biosimilar may be significantly less expensive. Some biosimilars also have their own savings programs.
