Warnings/Precautions:

Symptomatic response does not preclude gastric malignancy. Discontinue if acute interstitial nephritis, cutaneous/systemic lupus erythematosus occurs. Long-term therapy (eg, >3yrs) may lead to malabsorption or deficiency of Vit.B12. Use lowest dose for shortest duration appropriate to condition. Increased risk of osteoporosis-related fractures (hip, wrist, or spine) with long-term and multiple daily dose PPI therapy. Monitor magnesium levels with long-term therapy. Pregnancy.
