I have just received my first test results since being on
Crestor 10mg for 3 months. I had been on Lipitor10mg for
about 12 months, then went off for about 12 months, and have
now been on Crestor for 3 months.
While on Lipitor 10mg my AST level after 3 months was
34U/L and dropped to 28 U/L 5 months later. My CK on
Lipitor was 101 U/L.
Off Lipitor for 6 months my AST was 25 U/L and CK was 89 U/L
Now on Crestor for 3 months and my first results show AST as
being just above the upper limit at 41 U/L and my CK as
being 157 U/L
On Lipitor after 8 months my LDL and HDL were 78.73 and 50.5
mg/dL respectively.
On Crestor after 3 months my LDL and HDL are 70.25 and 57.12
mg/dL respectively.
My triglycerideshave always been pretty low and my HDL was
53.65 mg/dL before starting the Statin this time (I work out
a lot). My LDL was 133 mg/dL before beginning treatment.
I prefer not to go into why I am on a Statin in the first
place (no heart attack or heart disease though)
My question relates to the AST and CK levels. My CK is still
normal but higher than it was before, and my AST has risen
to 41 from 25.
I realise that according to the literature there is no great
concern for AST levels less than 3 times upper normal limit.
When I saw my family doctor today and went over the results
I didn't notice the AST nor did he mention them.
I am seeing my cardiologist this this Friday and plan to
discuss this with him as well as whether he thinks trying
5mg of Crestor would be appropriate given my quite low LDL
test levels now (would have to use a pill splitter) .
How bad is an AST increase from 25 to 41 after 3 months on
Crestor? CK from 89 (off statins) to 101 on Lipitor to 157
on Crestor. Again is this something to factor in when
balancing the risk/reward argument?
Will it (AST) come down as I take Crestor longer? (on
Lipitor it went down from 34 to 28, 5 months later)
Appreciate any informed replies.
Please no Statin bashing in this thread, it is irrelevant to
this discussion.
