The Non-Avian Options
If you have bird or egg allergies, your HA injection choices narrow significantly. Euflexxa and Durolane are the two main non-avian options—but they’re very different in how they’re administered.
The key tradeoff: Convenience (Durolane: 1 visit) vs. cost savings (Euflexxa: often cheaper).
Side-by-Side Comparison

| Source | Bacterial fermentation | NASHA technology |
| Bird allergy safe | Yes | Yes |
| Volume per injection | 2 mL each | 3 mL total |

Clinical Effectiveness
Both products provide effective relief for knee osteoarthritis:
- Pain reduction: Comparable in studies
- Duration of relief: Both ~6 months
- Function improvement: Similar outcomes
- Safety profile: Both well-tolerated
The evidence: No significant clinical difference between single-injection and multi-injection protocols when total HA volume is similar.
Making Your Decision
Choose Euflexxa if:
- Cost is your primary concern
- You can easily attend three weekly appointments
- You prefer smaller, individual injections
- Your insurance prefers or requires it
Choose Durolane if:
- Convenience is your priority
- You have a busy or unpredictable schedule
- You’re traveling and can’t return weekly
- You prefer getting treatment done in one visit
The Allergy Advantage
Both Are Safe for Avian Allergies
Whether you choose Euflexxa or Durolane, you’re protected:
- No rooster comb derivatives
- No egg proteins
- No bird-related allergens
- No feather concerns
This makes them the only options for patients who can’t use brands like Synvisc-One, Monovisc, or Gel-One.
Questions for Your Doctor
- Which product does my insurance cover better?
- How many appointments can I realistically make?
- Is there a clinical reason to prefer one over the other for my case?
- What’s the total out-of-pocket cost for each option?
- Do you have experience with both products?
The Bottom Line
Both Serve Allergy Patients Well
For patients with bird allergies, Euflexxa and Durolane are your two options—and both are effective.
- Euflexxa: Save money, invest time (3 visits)

Neither is objectively “better”—choose based on your schedule, budget, and preferences.
