Frequently Asked Questions

Common questions when looking up acid suppressants

I have been taking acid suppressants for a long time; can I stop taking them?

Whether you can stop depends on the reason for the prescription and the duration of use, so do not discontinue them arbitrarily. Since acid secretion may temporarily increase after sudden discontinuation, causing discomfort, please consult your prescribing medical provider regarding a plan for tapering or discontinuation.

Why do I still feel a lump in my throat and bloating even after taking the medication?

While acid reflux may have decreased, esophageal hypersensitivity, other causes of laryngopharyngeal issues, or functional dyspepsia may still persist. Instead of grouping everything as 'no effect,' please note how each symptom, such as acid regurgitation, heartburn, throat sensation, and bloating, has changed individually.
