Prilosec OTC (Omeprazole 20 mg) is a delayed-release acid reducer designed for frequent heartburn treatment. It belongs to a class of medications called proton pump inhibitors (PPIs), which work by reducing the amount of acid produced in the stomach. Unlike antacids that provide immediate relief, Prilosec OTC helps control acid production at the source, providing long-lasting relief when taken once daily. It is intended for a 14-day course of treatment for frequent heartburn (occurring 2 or more days per week). The delayed-release tablets are formulated to protect the medicine from stomach acid so it can work effectively in the digestive system.
