Recommendations for Labeling Medical Products Without Natural Rubber Latex
This guidance applies to all FDA regulated medical products (devices, drugs, biologics, and veterinary products) where natural rubber latex or its synthetic derivatives were not used in manufacturing the product, its container, or packaging.
Recommended Actions
- Review current product labeling for any “latex-free” or “does not contain latex” statements
- Update labeling to use the FDA recommended statement “Not made with natural rubber latex” or component-specific version
- Contact appropriate FDA Center for guidance on the regulatory mechanism to update labeling
- Consider removing latex-related statements entirely if not necessary
- Ensure understanding that no current test methods can guarantee complete absence of latex proteins
- Document the basis for any latex-related claims in product labeling
Key Considerations
Non-clinical testing
- No current analytical methods can identify all proteins and components in natural rubber latex that may lead to allergic reactions
- Three test methods available (ASTM D5712, ASTM D6499, ASTM D7427) but none can demonstrate complete absence of latex proteins
Labelling
- Do not use terms “latex-free” or “does not contain latex”
- Use “Not made with natural rubber latex” for the entire product
- Use “The [specific component] is not made with natural rubber latex” when referring to specific components
- Manufacturers should update existing labeling to use the recommended statements or remove latex-free type statements
Safety
- No threshold allergen levels are available for natural rubber latex-allergic individuals
- Multiple routes of exposure must be considered (respiratory, percutaneous, oral, and parenteral)
- At least 13 distinct allergens identified for natural rubber latex allergy
