Can codiene damage your stomach if you have had stomach ulcers in the past?

Yes, codeine can potentially irritate the stomach lining and may exacerbate existing gastrointestinal issues, including a history of stomach ulcers. Opioids like codeine can slow down gastrointestinal motility, leading to constipation and increased abdominal discomfort. If you have a history of stomach ulcers, it's essential to consult your healthcare provider before using codeine or any similar medications.
