I have been taking pantoprazole 40mg for at least 3
Polyp in your larynx then it's due to voice abuse, acid reflux
If you are having polyp in your larynx then it's due to voice abuse,overuse,acid reflux and not due to taking pantoprazole. Pantoprazole helps in preventing acid reflux and thus helps in preventing any vocal cord polyps.
Please consult ENT surgeon and opt for the options for treatment.
Hope this helps. Let me know if I can assist you further.
