Timing has a bigger impact on how well reflux medication works than most people realize, and different medication types need to be timed quite differently.
PPIs
PPIs work by blocking acid pumps that are most active during and after eating, so they're most effective when taken thirty to sixty minutes before the first meal of the day, giving the medication time to reach peak effect before acid production ramps up. Taking a PPI with food or right before a meal significantly reduces its effectiveness compared to the recommended timing.
H2 blockers
These work faster than PPIs and are often taken either on a regular schedule or as needed thirty minutes to an hour before a meal or bedtime, depending on whether the goal is general symptom prevention or targeting a specific known trigger time (like a big dinner or before lying down).
Antacids
These work immediately and are typically taken as needed for acute symptoms, either during an episode or preventively right before a meal or activity known to trigger symptoms — they don't need advance timing the way PPIs do, since their effect is immediate rather than building up over the day.
Getting timing right, especially for PPIs, is one of the simplest ways to get better results from a medication that may otherwise seem like it isn't working as well as it should.
