Hello and Welcome to Hcm.
I can completely understand your concern.
As per your history given,your doc changed your medication from
hydrochlorothiazide to ACCURETIC, which is a fixed-combination tablet that combines an angiotensin-converting enzyme (ACE) inhibitor,
quinapril hydrochloride, and hydrochlorothiazide.
As you are worried about your surgery, since I don't know what kind of surgery is it,I would recommend not to take the medication the day you're being operated.
As Hyrochlorothiazide being a
diuretic,may result in further fluid loss,Electrolyte disturbances, weakness,
hypotension,
And I would assure you that the
cough is not because of the new medications.Cough is not a side effect of either of the medications.That is completely coincidental.
Hope I helped you with your query.Kindly hit a Thanks.
Please Do write for any followup doubts or queries.
Thanks and wish You good Luck for your surgery.
Stay Healthy.
