Dear 4got,
Tylenol and zocor would be the most likely suspects from among that list of drugs but you are correct that the combination may also have an increased effect. Other causes of elevated liver enzymes (hepatitis, gall stones, etc.) must also be considered. Mildly elevated enzymes (<2-3 time upper limits of normal) are not cause for great concern and can be followed as an outpatient. I'm assuming your doctor is following you for this issue.
