The safest drug available that I take , And many other people I know take is called "Tenormin" or Atenlol , This medication is the only Beta Blocker that has not messed me up with me feeling sick or causing any side effects..
In fact I take 100 mg twice a day , And I don't see any side effect issues , Although I would like to go off of all medications some day but this one , Has been the only Beta Blocker that I can tolerate at the time..
I was on Nadolol (Corgard) And I was on Inderal( Propanolol) And I was on the newer form of Lopressor, called Metoprolol (Toprol) And I can't still tolerate the drug ..All I can say , Is talk to your doctor ..
