People who are prescribed lansoprazole may face various side effects, some of which could indicate a severe condition. Lansoprazole, a proton pump inhibitor akin to omeprazole, is commonly used to address stomach issues like heartburn, GERD, and stomach ulcers.

This medication works by reducing stomach acid production and is typically available in capsule or tablet form through a prescription. Patients are usually instructed to take lansoprazole once or twice daily, about 30 minutes before eating, for optimal efficacy, with dosage tailored to individual needs and health status.

Although lansoprazole can effectively manage stomach conditions, it carries a range of potential side effects. Some of these adverse effects may necessitate contacting a healthcare provider or emergency services, as they could signify a more serious issue, according to NHS guidance.

Common side effects of lansoprazole include stomach pain, affecting over 1 in 100 users. While mild in some cases, worsening stomach pain should prompt medical attention, as it may indicate an inflamed liver or pancreas. Additionally, persistent or severe diarrhea while taking the medication might signal an inflamed bowel.

Notably, severe side effects are rare, impacting less than 1 in 1,000 individuals using lansoprazole. Concerned users are encouraged to consult a pharmacist or GP for guidance on managing potential side effects.

While serious side effects rarely necessitate emergency services, specific symptoms may warrant a call to 999, especially if they suggest a severe allergic reaction to lansoprazole. More information on lansoprazole’s side effects and management strategies is available on the NHS website.
