This site states this specific caution directly: Immunosuppressants — some botanicals may affect immune function.
Why this caution is less specific than the other three
Worth noting this is the one medication caution on this site that doesn't name a specific botanical directly responsible — worth reading "some botanicals" as a more general caution than the specific Bromelain, Ginger and respiratory-medication points.
What to actually do about it
- Show this site's own label section to your doctor if you take immunosuppressant medication
- Discuss the full ingredient list, not just one named botanical
- Never adjust prescribed medication dosage based on a supplement alone
- Report any unusual symptom to your doctor promptly
💊 Medical note: BreathiZen contains botanicals such as Bromelain and Ginger that may affect blood clotting and interact with prescription medication. If you take blood thinners, respiratory medication or any regular prescription, show the label to your doctor before starting. Do not use if pregnant, nursing or under 18.
