Could Cyclobenzaprine Be The Cause For Liver Damage?

My husband had a mechanical valve put in about 3 yrs ago. He has been on heart meds since he was 12. He is not 48. Last summer he had a stroke. The neurologist put him on cyclobenzaprine.. His live counts and almost tripled. They did an ultrasound and said he had the start of liver damage. They told him to cut back on his alcholo. He's lucky he has one drink a month. Could the cyclobenzaprine be the cause of this??
