With the lowest dose of 12.5ml Hydrochlorothiazide I am still concern about the loss of Potassium. Is there any fruit or other type of over the counter meds that I can take to keep my potassium level normal? I am 67 with elevated blood pressure and taking 150ml of Avapro and one 12.5 Hydrochlorothiazide twice a week? Please advise?
