Prevacid 24 HR faces competition primarily from Omeprazole-based products, which dominate OTC PPI sales.
Consumer Demand and Usage Trends
- Growing GERD Incidence: Approximately 20% of U.S. adults diagnosed with GERD, driving OTC PPI demand.
- Long-Term Use Risks: Increasing awareness about potential adverse effects (e.g., kidney disease, fractures) curbs overuse but sustains OTC sales for chronic acid suppression management.
- OTC Transition Impact: Over-the-counter availability enhanced accessibility but limited premium pricing potential.
