Atenolol
"Taking Atenolol for 12 years, kept my BP in acceptable range (150/90) during all this time; suddenly BP went up to (170/120) every day, so I went to see Dr. who said Atenolol was "older treatment" and that much better drugs have come along since.  He put me on hydrochlorothiazide/ losartan (Hyzaar) and BP went even higher. Now after 2 weeks on Hyzaar, my BP is 190/130 consistently and I want to go back to Atenolol but Dr. says to give it the full 30 days to work.
