Summary
Thiazide-type diuretics are anionic drugs that may compete with the glucuronide metabolite of mycophenolic acid for renal tubular secretion. This could modestly raise metabolite levels, though the clinical significance is uncertain.
What this interaction means in plain words
Chlorthalidone and Mycophenolate 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
Possible competition for renal tubular anionic secretion of mycophenolic acid glucuronide; the clinical impact is not well characterized.
What to do
No dose change is routinely needed; monitor for mycophenolate adverse effects such as cytopenias and gastrointestinal intolerance.
