Summary
Hydrochlorothiazide is secreted in the proximal tubule and may compete with ganciclovir for elimination. Thiazide-induced volume depletion could also reduce renal clearance. Any increase in ganciclovir exposure is probably modest.
What this interaction means in plain words
Ganciclovir and Hydrochlorothiazide have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Ganciclovir belongs to Anti Virals; Hydrochlorothiazide belongs to Cardiovascular.
Why it happens
Possible competition for renal tubular secretion and reduced renal perfusion from volume depletion.
What to do
Monitor creatinine clearance and blood counts, and reduce the ganciclovir dose if renal function declines.
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?
