This will vary from brand to brand, but most intermittent catheter manufacturers today have attempted to remove latex from their catheters due to the risk of allergic reaction to latex. However, certain types of intermittent catheters such as red rubber catheters do contain latex. The Food and Drug Administration (the FDA) requires medical devices that contain latex to be identified by including a latex warning statement on the product label.
If you have a latex allergy, be sure to tell your healthcare provider as well as your the intermittent catheter supplier to ensure the supplies you receive will be latex-free.
