Omeprazole step-down + alginate after meals + famotidine PRN (12 wks update): Background: 3 years on omeprazole 20 mg for GERD and gastritis, with my doctor's agreement... — what worked for others here?
Background: 3 years on omeprazole 20 mg for GERD and gastritis, with my doctor's agreement to try tapering. Weeks 1-4: omeprazole 30 minutes before breakfast every other day. Alginate liquid (10 mL) after dinner and at bedtime. Famotidine 10 mg only on bad nights, no more than 3 nights per week to avoid tolerance. Rebound heartburn peaked around week 2 and eased by week 5. Weeks 5-12: omeprazole only on trigger days. Lifestyle changes: dinner 3+ hours before bed, smaller portions, and head-of-bed elevation. Labs at the start showed magnesium 1.8 mg/dL and B12 410 pg/mL. Not perfect, as I still need a PPI occasionally, but my average is now 2-3 doses weekly.
PubMed: Reimer et al. (Gastroenterology 2009) found transient rebound acid symptoms in 44% of volunteers after PPI withdrawal, which supports a gradual step-down. FDA DailyMed omeprazole labeling advises taking the dose 30-60 minutes before a meal and using the lowest effective dose.
