As Per Doctor's Advice, I Have Been Taking Rosavel F-20

As per doctor's advice, I have been taking rosavel F-20 (OD) on regular basis since Oct./15 as my cholestorel & TG level was high detected by lipid profile test and I have to continue this medicine for 1 year as advised by doctor. But recently I have been feeling acute body ache as well as strong indigestion & acidity. Bowels also not clear and also feeling drowsiness. Is this the side effect of the said medicine. Please advise.
