Hey all, first-time poster here. I was diagnosed with acid reflux about 6 months ago and have been on Pariet (a PPI) ever since. At first I experienced stomachaches and pretty bad headaches but these supposedly 'rare' side effects did go away. A few weeks ago I noticed a feeling of breathlessness. Being somewhat of a hypochondriac I started worrying about it and the breathlessness has persisted these past weeks. Breathing problems are listed as a possible 'very rare' side effect in the medication pamphlet. Has anybody here experienced similar problems with a PPI?
