Summary
Sodium citrate with citric acid is a buffered alkalinizing solution. Its theoretical ability to neutralize colonic acidification from lactulose is minor and no important clinical effect is documented.
What this interaction means in plain words
Lactulose and Sodium citrate / citric acid have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Citrate is metabolized to bicarbonate, which may theoretically offset lactulose-induced colonic acidification; this has not been established.
What to do
No routine action is required. Monitor stool output and ammonia-related symptoms if lactulose is given for hepatic encephalopathy.
