Alpinia and Omeprazole, Sodium Bicarbonate

Here is the interaction we found between these two, with the evidence behind it.

Minor

PROTON PUMP INHIBITORS (PPIs)

Why this applies to Omeprazole, Sodium Bicarbonate

Omeprazole, Sodium Bicarbonate falls under PROTON PUMP INHIBITORS (PPIs) — the group Alpinia interacts with.

Theoretically, alpinia might decrease the effectiveness of PPIs.
There are some reports suggesting that alpinia increases stomach acid.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Your Konvomep combines omeprazole (a proton pump inhibitor that lowers stomach acid) with sodium bicarbonate to protect that drug. The concern with alpinia is the opposite direction: a few anecdotal reports suggest this root may actually nudge stomach acid up. If that happens, it could slightly work against what your medicine is trying to do, so heartburn or reflux symptoms might not be as well controlled.

I want to keep this in perspective. This is rated minor and rests on very weak, anecdotal evidence, not solid human studies. Everyday culinary amounts (like alpinia in cooking) are unlikely to matter. Concentrated supplements are more of a question mark. If you take one and notice your reflux creeping back, check in with your pharmacist or doctor before changing anything.

About Alpinia

What is Alpinia?

Alpinia
  • Digestive upset and bloating
  • Nausea
  • Anti-inflammatory support
  • Respiratory and cough complaints
  • Antimicrobial
  • Appetite stimulant

Alpinia (lesser galangal) is a ginger-family root long used in Asian cooking and traditional medicine, mainly for digestive and inflammatory complaints. Most of its proposed health benefits come from laboratory and animal studies, and strong human evidence is lacking. Food amounts are generally well tolerated, but talk with your pharmacist or doctor before using concentrated supplements.
