Have been on Zocor 40mg for years. Last year, developed problem, Dr. Suggested going off Zocor for 2 months,after which cholesterol totals became very high, 398. Went back on it a year ago. Experiencing nausea,leg cramps, and liver enzymes have increased. Dr. Now tells me to d/C Zocor to see if liver enzymes decrease and nausea subsides. But what about my cholesterol levels? Last time went off, levels skyrocketed. I am female,69 years old.
