OMECROSS 20MG CAP
OMEPRAZOLE 20MG
OMECROSS 20MG CAP is a capsule of omeprazole 20 mg, a proton pump inhibitor. It is used for gastro-oesophageal reflux disease, peptic ulcer disease, acid dyspepsia, the prevention of NSAID-related ulceration, and as part of Helicobacter pylori eradication regimens.
01
Benefits
- Blocks the gastric proton pump directly, producing more complete and sustained acid suppression than H2 blockers.
- Heals oesophagitis and peptic ulcers reliably, and relieves reflux symptoms in most patients.
- Once-daily dosing gives cover across the full day.
- A standard component of Helicobacter pylori eradication therapy alongside two antibiotics.
- Effective gastroprotection in patients who need to continue NSAIDs despite ulcer risk.
02

Stop and get medical help if any of these occur
- Severe or persistent diarrhoea, which may indicate Clostridioides difficile infection
- Severe muscle cramps, weakness, tremor or an irregular heartbeat, which may indicate low magnesium
- Black or tarry stools, or vomiting of blood
- Difficulty swallowing, unexplained weight loss or persistent vomiting
- Widespread rash with blistering or peeling skin
- Reduced urine output or blood in the urine
03
Precautions
- Take thirty to sixty minutes before food. A proton pump inhibitor taken after a meal is substantially less effective, and this is the commonest reason for apparent treatment failure.
- Alarm features — weight loss, difficulty swallowing, vomiting blood, black stools, anaemia — need investigation before starting, as acid suppression can mask gastric malignancy.
- Long-term use is associated with low magnesium and vitamin B12, an increased risk of fracture, and enteric infection including Clostridioides difficile. Review the need periodically rather than continuing indefinitely.
- Omeprazole reduces the effect of clopidogrel — discuss an alternative proton pump inhibitor in patients on it.
- Reduced gastric acidity impairs absorption of ketoconazole, itraconazole, iron and some antiretrovirals.
- Swallow the capsule whole; do not crush or chew, as this destroys the acid-resistant coating.
- Dose reduction may be required in significant hepatic impairment.
- Use in pregnancy and breastfeeding only on medical advice.
