Emergency Omeprazole Prescribing Information
Immediate Dosing Protocol
Omeprazole 20mg once daily represents the standard starting dose for gastro-oesophageal reflux disease and dyspepsia according to BNF guidelines. For severe symptoms, healthcare professionals may consider increasing to 40mg daily. EverydayMeds stocks omeprazole 20mg capsules and Losec MUPS tablets for immediate dispensing following appropriate consultation.
Critical Safety Information
Contraindications include known hypersensitivity to omeprazole or other proton pump inhibitors. Caution required in patients with severe hepatic impairment, as dose reduction may be necessary. Long-term use requires periodic review due to potential risks including hypomagnesaemia, vitamin B12 deficiency, and increased fracture risk in elderly patients.
Drug Interactions
Significant interactions occur with clopidogrel (reduced antiplatelet effect), warfarin (enhanced anticoagulation), and atazanavir (reduced absorption). Monitor closely when co-prescribing with digoxin, phenytoin, or cilostazol. Omeprazole may affect absorption of pH-dependent drugs including ketoconazole and iron supplements.
Alternative Treatment Options
When omeprazole proves unsuitable, alternative proton pump inhibitors available through EverydayMeds include lansoprazole 15mg, pantoprazole 20mg, and esomeprazole tablets. For patients requiring H2 receptor antagonist therapy, famotidine tablets provide an alternative mechanism for acid suppression with different interaction profiles.
Emergency Prescribing Considerations
In urgent situations, omeprazole may be initiated immediately whilst investigating underlying pathology. Red flag symptoms requiring immediate specialist referral include dysphagia, unintentional weight loss, persistent vomiting, or signs of gastrointestinal bleeding. Consider Helicobacter pylori testing in treatment-resistant cases, particularly in younger patients without alarm symptoms.
