Hello, 
I think the correct medication you are taking is 
Tizanidine 2 mg. It is used to treat muscle spasms. One of its side effects is injuring the 
liver, which is already affected (high AST and 
ALT). 
You are also reporting to be using medications to lower 
high cholesterol (most probably statins). They also have been shown to injure the liver. 
So, to me, in your case, both medications are causing injured liver with high AST and ALT. Should run 
hepatitis tests to rule out hepatitis. 
If negative, should discuss with your caring doctor to stop taking these meds until the liver is stabilized. Or can change therapy.
Hope I have answered your query. Let me know if I can assist you further. 
Regards,
Dr. Albana Sejdini, General & Family Physician
