I have recently been put on lipitor after a catherization and I am extremely tired I have no energy and need to take a nap which I have never done before because I am so tired I am 82 years old and have been on prevastatin and zocor before. I will get in touch with my cardiologist on Monday.. My catherization was on August 31 and I saw the doctor a week ago but the tiredness seems to be getting worse as this week went on I am concerned because it comes on fast and I need to lie down right away. Thank you
