What medicine can you get in Korea when you experience heartburn, acid reflux, or water brash?
Let’s focus on over-the-counter (OTC) antacids, which are widely available in Korean pharmacies.
What is an Antacid?
Antacids are medications that neutralize stomach acid.
They are commonly used for:
- Heartburn (acid reflux)
- Water brash (acid regurgitation)
- Indigestion (dyspepsia)
- Gastritis-related discomfort
✔ Mechanism
Antacids contain alkaline substances that chemically neutralize gastric acid (HCl) in the stomach.
👉 This provides rapid symptom relief, usually within minutes.

Important: Combination Ingredients You May See
Many Korean antacids include additional components:
- Simethicone → relieves gas/bloating
- Sodium alginate → prevents reflux
- Oxetacaine → relieves pain
👉 This is why products differ in effect even if all are called “antacids.”
Side Effects (Important Differences)
Even though many antacids are similar, side effects differ:
- Constipation → more likely with aluminum-containing products
- Diarrhea → more likely with magnesium-containing products
👉 Combination products are designed to balance these effects, but sensitivity varies.

Important Considerations (Clinical Perspective)
Because many products are:
- multi-ingredient combinations
- tailored for different symptoms
👉 The “best” medication varies depending on:
- simple heartburn
- Gas/bloating
- Pain severity
- Individual sensitivity (constipation/diarrhea)
→ If you are taking other medications, it is recommended to take them with a time interval (at least 2 hours).
→ Please also be careful taking with milk!
