Understanding Omeprazole Side Effects and Management

Common Side Effects of Prescription Omeprazole

Most patients tolerate omeprazole well, but some may experience mild side effects. Common reactions include headaches, stomach pain, nausea, diarrhoea, constipation, and flatulence. These typically resolve within a few days as your body adjusts to the medication. EverydayMeds provides comprehensive patient information with all omeprazole prescriptions to help you identify and manage these effects.

Long-term Side Effects to Monitor

Extended omeprazole use may cause vitamin B12 deficiency, low magnesium levels, and increased infection risk. Patients on long-term treatment should have regular blood tests to monitor nutrient levels. Some studies suggest potential bone fracture risk with prolonged high-dose use, particularly in elderly patients or those with existing osteoporosis risk factors.

When to Seek Medical Advice

Contact your healthcare provider immediately if you experience severe diarrhoea that doesn't improve, persistent stomach pain, signs of liver problems (yellowing skin, dark urine), or severe skin reactions. EverydayMeds' clinical team is available for consultation if you have concerns about your omeprazole treatment or experience unexpected side effects.

Purchasing Omeprazole Through EverydayMeds

EverydayMeds UK offers omeprazole 20mg capsules and Losec MUPS 20mg tablets through our secure online pharmacy. Our qualified prescribers conduct thorough consultations to ensure omeprazole is suitable for your condition and medical history.
