Indications for: PREVACID
Triple therapy (w. amoxicillin + clarithromycin) or dual therapy (w. amoxicillin; use only if allergic, intolerant, or resistant to clarithromycin) for H. pylori eradication in duodenal ulcer disease. Short-term treatment of active duodenal ulcer, active benign gastric ulcer, erosive esophagitis (EE), symptomatic GERD, and NSAID-associated gastric ulcers when NSAID use is continued. To reduce risk of NSAID-associated gastric ulcer in patients with history of gastric ulcer who need an NSAID. Maintenance of healing of duodenal ulcer, EE. Long-term treatment of pathological hypersecretory conditions (eg, Zollinger-Ellison syndrome).

EE treatment: 30mg once daily for up to 8 weeks; may repeat for 8 more weeks. If relapse occurs, may repeat 8-week course. GERD: 15mg once daily for up to 8 weeks. Maintenance of healing of duodenal ulcer or EE: 15mg once daily. Healing of NSAID-associated gastric ulcer: 30mg once daily for 8 weeks; NSAID ulcer risk reduction: 15mg once daily for up to 12 weeks. Hypersecretory conditions: Initially 60mg once daily, adjust as needed; give daily doses >120mg in divided doses. Severe hepatic impairment: 15mg once daily.
Take before eating. Do not crush or chew granules. Caps: swallow whole, or sprinkle granules and mix contents with food or juice (see full labeling) and take immediately.

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 for fundic gland polyps with long-term use (esp. >1yr) or risk for 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. SoluTabs: phenylketonuria. Severe hepatic impairment: reduce dose. Risk of heart valve thickening (in children <1yr old). Pregnancy. Nursing mothers.
Proton pump inhibitor.
Concomitant St. John's wort, rifampin, atazanavir, nelfinavir: not recommended. May potentiate digoxin, tacrolimus, methotrexate, saquinavir; monitor. Potentiated by voriconazole. May alter absorption of pH-dependent drugs (eg, ketoconazole/itraconazole, iron salts, erlotinib, mycophenolate mofetil, dasatinib, nilotinib). Concomitant digoxin, diuretics may predispose patients to hypomagnesemia. Monitor theophylline, warfarin. Give at least 30 mins before sucralfate. May give antacids concomitantly. May interfere with neuroendocrine tumor diagnostic tests; discontinue lansoprazole at least 14 days prior to CgA level assessment. Interrupt therapy at least 28 days before secretin stimulation test. May cause false (+) urine screening tests for THC.
Diarrhea, abdominal pain, nausea, constipation, headache, bone fracture; possible C. difficile-associated diarrhea (esp. if hospitalized); rare: hypomagnesemia and mineral metabolism.
