NEXIUM Warnings/Precautions:

Symptomatic response does not preclude gastric malignancy. Discontinue and evaluate if acute tubulointerstitial nephritis, severe cutaneous adverse reactions, or cutaneous/systemic lupus erythematosus occurs. Long-term therapy (eg, >3yrs) may lead to malabsorption/deficiency of Vit. B12. Monitor magnesium levels during prolonged therapy. Consider monitoring magnesium, calcium levels in those with preexisting risk of hypocalcemia (eg, hypoparathyroidism). Increased risk of fundic gland polyps with long-term use (esp. >1yr) or osteoporosis-related fractures (hip, wrist or spine) with long-term (>1yr) and multiple daily dose PPI therapy. Use lowest dose for shortest duration appropriate to condition. Pregnancy. Nursing mothers.

NEXIUM Classification:

Proton pump inhibitor.

NEXIUM Interactions:

Avoid concomitant St. John's wort, rifampin, nelfinavir. May potentiate saquinavir; monitor for toxicity. May reduce absorption of gastric pH-dependent drugs (eg, iron salts, erlotinib, dasatinib, nilotinib, mycophenolate mofetil, ketoconazole, itraconazole). Antagonizes clopidogrel; consider alternative anti-platelets. May affect drugs metabolized by CYP2C19. May potentiate digoxin, tacrolimus, cilostazol (consider reduced dose), citalopram (limit dose to max 20mg/day), high-dose methotrexate (consider temporary withdrawal of PPI). Caution with drugs that may cause hypomagnesemia (eg, digoxin, diuretics); monitor. Monitor INR, PT with warfarin. Potentiated by voriconazole; may need to adjust esomeprazole dose in Zollinger-Ellison syndrome. May give antacids concomitantly. May cause false (+) results in diagnostic investigations for neuroendocrine tumors; discontinue esomeprazole 14 days prior to CgA level assessment; may need repeat test. May cause false (+) results with secretin stimulation test or urine tests for tetrahydrocannabinol.

Adverse Reactions:

Headache, diarrhea, abdominal pain, nausea, flatulence, constipation, dry mouth, inj site reactions, dizziness, vertigo; possible C. difficile-associated diarrhea; rare: rash, allergic reactions, hypomagnesemia and mineral metabolism. Children: Also, somnolence, regurgitation, tachypnea, increased ALT.
