Suggest Dosage And Side Effects Of Rosuvas

I am using Rosuvas F10 last 8 months, That time Cholesterol was Total - 267, HDL 50, LDL 161, Triglyceride 292,
But now My Cholesterol levels are Total-158, HDL 49, LDL 86, Triglyceride 114.
Can I continue to use Rosuvas F10 even my Cholesterol is in normal range? Or can I reduce the dose?
If I am continuing , what is the side effects, how to avoid those?

Thank you in advance.
