Complete Omeprazole Side Effects Overview
Common Side Effects (Affecting 1 in 10 People)
The most frequently reported side effects of omeprazole include headache, nausea, stomach pain, constipation, diarrhoea, and wind. These effects are typically mild and often improve as your body adjusts to the medication. If symptoms persist or worsen after the first week, consult your healthcare provider.
Less Common Side Effects (Affecting 1 in 100 People)
Some patients may experience dizziness, drowsiness, sleep problems, skin rashes, itchy skin, swollen feet or ankles, or generally feeling unwell. Changes in liver enzyme levels may occur but usually return to normal when treatment stops. These effects don't necessarily require stopping treatment but should be discussed with your pharmacist or doctor.
Serious Side Effects (Rare but Important)
Seek immediate medical attention if you experience severe diarrhoea with blood or mucus, yellowing of skin or eyes, joint pain with red skin rash, severe stomach pain, or signs of low magnesium including muscle cramps, irregular heartbeat, or seizures. Severe allergic reactions, whilst extremely rare, require emergency treatment.
Long-term Use Considerations
Extended omeprazole use may increase infection risk, particularly C. difficile-associated diarrhoea. Regular monitoring may be recommended for vitamin B12 deficiency, low magnesium levels, and bone health, especially in elderly patients or those taking high doses for extended periods.
