Although the most prevalent and common side effects of ATORVASTATIN
are musculoskeletal side effects like myalgia and arthralgia
.In some cases myopathy and rhabdomylosis have also been seen but very rarely.
However in few cases ,as in you,heartburn,flatulence
,dyspepsia,coughing,dizziness,drowsiness etc has been seen.
You should stop the medicine and ask your doctor for an alternative prescription of anti cholesterol
I hope it helps.
