Can Hydrochlorothiazide be the cause of a false POSITIVE home pregnancy test?
Patient: I'm sure these are silly questions, but I'm grasping at straws here.  Can hydrochlorothiazide 12.5 mg be the cause of a false POSITIVE home pregnancy test?  I took a Clearblue pregnancy test this morning and it seemed to be missing that all important word..."not".  Uh oh.  I am 46 years old.  I am not menopausal.  Could my age also influence a false positive?  Thank you Doctor: Hi,Welcome to Healthcaremagic,After going through your history,This medication would not affect a pregnancy test.If you have tested at least two weeks after a missed period, and you had unprotected sex during this period, then visit Gynecologist and confirm it with blood test Beta HCG level which is 99.9% accurate and a ultrasonography may be done to confirm.If you do not want to continue pregnancy medical and surgical options to terminate are available.your Gynecologist would guide you for what is best for you.First we need to exclude pregnancy than other causes of amenorrhoea can be analysed and investigated if required.Hope this helps you.Take care.Good Luck.Dr.Akhilesh Dubey M.D.
