Omeprazole dosing depends on the condition being treated and individual factors. A common range for adults is 20 mg to 40 mg taken once daily before a meal, with higher daily doses sometimes used for more complex conditions, and doses above about 80 mg per day typically given in divided doses under medical supervision. Always follow your clinician’s instructions and use the lowest effective dose for the shortest appropriate duration. Key points to consider:
- For GERD with symptoms or non‑erosive disease: often 20 mg once daily for several weeks.
- For erosive esophagitis or peptic ulcers: typically 20–40 mg once daily for a few to several weeks.
- For Helicobacter pylori-related ulcers: commonly a combination regimen with antibiotics, as directed by your doctor.
- Zollinger-Ellison syndrome or other complex acid disorders: may require higher, tailored dosing under specialist care.
- Long-term or high-dose use requires medical supervision due to potential risks and interactions.
- If you miss a dose, take it as soon as you remember unless it’s nearly time for your next dose; do not double up routinely.
Safety notes:
- Do not take more than prescribed. If you suspect overdosing or experience severe symptoms, seek medical attention.
- Certain medical conditions and other medications can affect omeprazole dosing or increase risk of interactions.
- If you have liver disease, are pregnant or breastfeeding, or take other acid-reducing medicines, talk to your healthcare provider for personalized guidance.
If you’d like, share your specific condition (for example, GERD, ulcers, or H. pylori treatment) and any other medications you take, and I can summarize the typical dosing range you’re likely to encounter and what factors might lead to adjustments.
