Precautions
Gastric malignancy should be ruled out. Pregnancy, lactation, childn <1 yr. Monitoring Parameters Monitor Mg concentrations prior to initiation and periodically thereafter.
Lactation
Risk Summary
Limited data suggest omeprazole may be present in human milk; there are no clinical data on effects of omeprazole on breastfed infant or on milk production; developmental and health benefits of breastfeeding should be considered along with mother's clinical need for therapy and any potential adverse effects on breastfed infant from treatment or from underlying maternal condition
Pregnancy-Lactation
Risk Summary
There are no adequate and well-controlled studies with Omeprazole in pregnant women. Available epidemiologic data fail to demonstrate an increased risk of major congenital malformations or other adverse pregnancy outcomes with first trimester omeprazole use. Reproduction studies in rats and rabbits resulted in dose-dependent embryo-lethality at omeprazole doses that were approximately 3.4 to 34 times an oral human dose of 40 mg (based on a body surface area for a 60 kg person).
Teratogenicity was not observed in animal reproduction studies with administration of oral esomeprazole (an enantiomer of omeprazole) magnesium in rats and rabbits during organogenesis with doses about 68 times and 42 times, respectively, an oral human dose of 40 mg esomeprazole or 40 mg omeprazole (based on body surface area for a 60 kg person). Changes in bone morphology were observed in offspring of rats dosed through most of pregnancy and lactation at doses equal to or greater than approximately 34 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole. When maternal administration was confined to gestation only, there were no effects on bone physeal morphology in the offspring at any age.
Interactions
Increased risk of hypomagnesaemia w/ diuretics. May increase INR and prothrombin time w/ warfarin. Increased risk of digoxin-induced cardiotoxic effects. May increase plasma concentration benzodiazepines (e.g. diazepam), clarithromycin and methotrexate. Decreased absorption of itraconazole, ketoconazole, posaconazole, dasatinib, iron salts. May prolong elimination of diazepam, cilostazol, phenytoin and ciclosporin. May reduce the antiplatelet effect of clopidogrel.
Potentially Fatal: May decrease plasma concentrations and pharmacological effects of rilpivirine, nelfinavir and atazanavir.

Mechanism of Action
Omeprazole is a substituted benzimidazole gastric antisecretory agent and is also known as PPI. It blocks the final step in gastric acid secretion by specific inhibition of H+/K+ ATPase enzyme system present on the secretory surface of the gastric parietal cell. Both basal and stimulated acid are inhibited.
