I changed Drs. and my new one doesn't care for Lipitor (not sure why). He said he preferred tp prescribe Zocor and, since my lab work was pending and I was out of meds, he reached into a desk drawer and pulled a small booklet out and cross referenced what a like dose of Zocor would be to 20mg. of Lipitor. It has been some time, labs are back, and my dosage has stayed the same. Now he wants me to change to Lovastatin and I was curious if the dosage would increase, decrease or remain the same since all 3 seem to be of the same family. I have asked him but he has a very thick accent and I don't hear well so it is difficult for me to understand. Thank you
