I have tried Simvastin, Pravastatin, Exetermibe, and have now been put on Atorvastin. Have been on them, 20mg for several months, and so far no side effect that I am aware of, but the others gave me terrible muscle pain in my back. I stopped and started each of them, to find out if it was definitely the medication. My cholesterol was such that it was decided to try another, so far so good, and next week I have an appointment at the doctor when I am expecting to be given a higher dosage of Atorvastin.
My husband is on Simvastin, and has had no problems.
