warnings and cautions
5 WARNINGS AND PRECAUTIONS Gastric Malignancy : In adults, symptomatic response does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing. ( 5.1 ) Acute Tubulointerstitial Nephritis: Discontinue treatment and evaluate patients. ( 5.2 ) Sodium Bicarbonate Buffer Content : Take sodium content into consideration in patients on a sodium-restricted diet. Avoid in patients with Bartter’s syndrome, hypokalemia, hypocalcemia, and problems with acid-base balance. ( 5.3 ) Clostridium difficile -Associated Diarrhea : PPI therapy may be associated with increased risk. ( 5.4 ) Bone Fracture : Long-term and multiple daily dose PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine. ( 5.5 ) Severe Cutaneous Adverse Reactions: Discontinue at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation. ( 5.6 ) Cutaneous and Systemic Lupus Erythematosus : Mostly cutaneous; new onset or exacerbation of existing disease; discontinue Omeprazole and Sodium Bicarbonate and refer to specialist for evaluation. ( 5.7 ) Interaction with Clopidogrel : Avoid concomitant use of Omeprazole and Sodium Bicarbonate. ( 5.8 ) Cyanocobalamin (Vitamin B-12) Deficiency : Daily long-term use (e.g., longer than 3 years) may lead to malabsorption or a deficiency of cyanocobalamin. ( 5.9 ) Hypomagnesemia and Mineral Metabolism : Reported rarely with prolonged treatment with PPIs. ( 5.10 ) Interaction with St. John’s wort or Rifampin : Avoid concomitant use of Omeprazole and Sodium Bicarbonate. ( 5.11 , 7 ) Interactions with Diagnostic Investigations for Neuroendocrine Tumors : Increased Chromogranin A (CgA) levels may interfere with diagnostic investigations for neuroendocrine tumors; temporarily stop Omeprazole and Sodium Bicarbonate at least 14 days before assessing CgA levels. ( 5.12 ) Interaction with Methotrexate : Concomitant use with PPIs may elevate and/or prolong serum concentrations of methotrexate and/or its metabolite, possibly leading to toxicity. With high dose methotrexate administration, consider a temporary withdrawal of Omeprazole and Sodium Bicarbonate. ( 5.13 , 7 ) Fundic Gland Polyps : Risk increases with long-term use, especially beyond one year. Use the shortest duration of therapy. ( 5.14 ) 5.1...

6 ADVERSE REACTIONS The following serious adverse reactions are described below and elsewhere in labeling: Acute Tubulointerstitial Nephritis [see Warnings and Precautions (5.2) ] Clostridium difficile -Associated Diarrhea [see Warnings and Precautions (5.4) ] Bone Fracture [see Warnings and Precautions (5.5) ] Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.6) ] Cutaneous and Systemic Lupus Erythematosus [see Warnings and Precautions (5.7) ] Cyanocobalamin (Vitamin B-12) Deficiency [see Warnings and Precautions (5.9) ] Hypomagnesemia and Mineral Metabolism [see Warnings and Precautions (5.10) ] Fundic Gland Polyps [see Warnings and Precautions (5.14) ] Most common adverse reactions (≥2%) are: headache, abdominal pain, nausea, diarrhea, vomiting, and flatulence. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Oceanside Pharmaceuticals at 1-800-321-4576 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of Omeprazole and Sodium Bicarbonate has been established, in part, based on oral studies of an oral delayed-release omeprazole product. Clinical Trials with Omeprazole In the U.S. clinical trial population of 465 adult patients, the adverse reactions summarized in Table 3 were reported to occur in 1% or more of patients on therapy with omeprazole.
