Atenolol
"I am 49 yr old female. Have taken combination of atenolol/chlorothiazide 50/25 plus another one for 11 years. The past four years I have developed an unexplained itch (no outside rash) so I have to take an antihistamine everyday, muscle/joint pain so bad I take a pain pill for that. Swelling of hands and feet/ dangerously low Potassium levels. After reading over the side effects I took myself off it, I have changed doctors and hopefully can get on something better. I have been off it two weeks and I feel so good. No itching, no pain, no extra pills..blood pressure is up but that can be taken care of. I think it had built up in my system to a toxic level. It did the job, just added to many other issues after so many years of use. Good luck everyone."
