High Blood Pressure
"I&#039;ve been on 25 mgs. of Atenolol for 10 years.  Have heard in recent years, that after such time  They are finding IF you&#039;re over 60, you should consider switching to another BB.  That supposedly it (atenolol) loses it&#039;s effectiveness.  Well when you start researching ALL the beta blockers currently on the market?  You will find that most of them have side effects far more than Atenolol, and while I haven&#039;t had any real symptoms, I&#039;m guessing I should &quot;stay put&quot; with Atenolol unless it fails to do the job in the future."
