In general, long-term treatment with PPIs like Prilosec is safe. However, it is associated with some conditions, such as B-12 deficiency, colitis, as well as atrophic gastritis.
There are no clear recommendations as to how to titrate off PPIs. Some physicians do a "step-down" approach. This involves an incremental decrease in PPIs, and re-evaluation every 2-4 weeks. If symptom-free, the dose of PPI can be further decreased or discontinued.
Some physicians simply do a trial off medication, with the need for maintainence medication dependent on recurrent symptoms. Recurrence of symptoms within 3 months of stopping the medication is an indication for continuing an acid-suppressant.
The best course should be discussed with your gastroenterologist or personal physician.
Followup with your personal physician is essential.
