Summary
Chlorthalidone is secreted by renal tubular transporters and could theoretically reduce ganciclovir clearance. Diuretic-induced volume depletion may also lower renal function. The clinical effect is expected to be small.
What this interaction means in plain words
Chlorthalidone and Ganciclovir have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Chlorthalidone belongs to Cardiovascular; Ganciclovir belongs to Anti Virals.
Why it happens
Theoretical competition for tubular secretion, with possible reduction in glomerular filtration from volume depletion.
What to do
Monitor serum creatinine and hydration status, and adjust the ganciclovir dose if creatinine clearance falls.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
