Summary

What this interaction means in plain words
Carbenoxolone and Enalapril-hydrochlorothiazide can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens

What to do
Avoid the combination where possible; if used, monitor serum potassium and blood pressure and supplement potassium as needed.
