Less common side effects may include nausea and vomiting. Long-term use may potentially lead to low magnesium levels and an increased risk of bone fractures.

Precautions: Zilon (Omeprazole) is contraindicated in patients with known hypersensitivity to omeprazole or any of the components of this medication. Gastric malignancy should be ruled out before initiating therapy. Caution should be exercised in pregnant and breastfeeding women, and the daily dose in elderly patients should, as a rule, not exceed 20 mg. In patients with severe liver disease, dose adjustment may be needed.

Omeprazole can delay the elimination of diazepam, phenytoin, and warfarin. There is no evidence of interaction with theophylline, propranolol, metoprolol, lidocaine, quinidine, amoxicillin, or antacids. The absorption of Omeprazole is not affected by alcohol or food, although it is recommended to take it before meals. Concomitant use with clopidogrel should be avoided as omeprazole may reduce its pharmacological activity.

Use in Pregnancy and Lactation: The safety of Omeprazole in pregnancy has not been established. It should not be administered to pregnant women unless the expected benefits outweigh the potential risks. It is not known if Omeprazole is secreted in human milk and should not be given to nursing mothers unless its use is considered essential.

Storage: Keep away from light and store below 30°C. Keep out of the reach of children.
