For people looking to reduce or avoid PPI use, there are real alternatives worth knowing about, though it's important to set expectations honestly: none of them match a PPI's acid-suppressing power for significant reflux.
Other medication classes
H2 blockers (like famotidine) reduce acid production through a different, generally milder mechanism than PPIs and work well for some people with less severe reflux. Antacids provide fast, short-acting relief by directly neutralizing acid but don't address ongoing symptom prevention the way PPIs or H2 blockers do.
Lifestyle changes that reduce reliance on medication
Weight management (if relevant), smaller and earlier meals, elevating the head of the bed, and identifying and avoiding personal trigger foods can meaningfully reduce symptom frequency and severity, sometimes enough to lower medication needs, even if they don't fully replace medication for moderate-to-severe reflux.
A realistic way to approach reducing PPI use
Tapering under a doctor's guidance, rather than stopping abruptly, while adding lifestyle changes and possibly an H2 blocker as a bridge, tends to go more smoothly than an abrupt switch, since sudden PPI discontinuation can cause a temporary rebound increase in acid production.
