FDA Requirements for Antacid Drug Products
Antacid drug products are regulated as OTC drugs. Active ingredients in OTC antacids include calcium carbonate, magnesium hydroxide, aluminum hydroxide, magnesium oxide, and sodium bicarbonate.
All antacid manufacturers must register with FDA as drug establishments, obtain an NDC labeler code, and list each product with Drug Facts labeling.
- FDA Drug Establishment Registration
- NDC Labeler Code — required for all antacid products
- Drug Listing in SPL format with Drug Facts panel
- Annual renewal required October 1–December 31
- GMP compliance under 21 CFR Parts 210 & 211
Antacids are over-the-counter (OTC) monograph drugs, meaning they’ve been evaluated by the FDA for safety and effectiveness and are generally safe for self-care. Antacids relieve heartburn (indigestion). They work by changing the stomach acid that causes heartburn, acid indigestion, and upset stomach. However, antacids don’t address the root cause of these issues and shouldn’t be used for prolonged periods without consulting a doctor.
