I have been taking Lisinopril and Hydrochlorothiazide (HTCZ) for high blood pressure since May 2007.
Recently I have a feeling that the Hydrochlorothiazide is not working as it used to be.
Will HCTZ lose its effectiveness after a certain number of years?
Anyone know the answer or having similar experience, please let me know.
