I'm a 66 year old nurse taking Lipitor 10 mg for approximately 4 years. I have not had any problems until last when I suffered a severe anxiety attack and went to the ER. This has never happened to me before. All tests were negative. I was given Xanax which relieved the anxiety at that time , but I 'm continuing to experience a lot of anxiety. I came across some info that low cholesterol levels can be related to anxiety. My total cholesterol is 130 and the LDL is 71. I have no cardiac conditions other than hypertension. I stopped taking Lipitor a couple of days ago, but so far I have not had any change in condition. Dr ordered Zoloft for the anxiety but I had bad reactions after taking 2 pills.-severe nervousness, anxiety , and restlessness. I'm hoping I feel better when the cholesterol levels go up.
