Adverse reactions have usually been mild transient. They include abdominal pain, asthenia, constipation, diarrhoea, dyspepsia, flatulence, nausea, headache, upper respiratory infections.
Myopathy has been rarely reported.
There have been rare post-marketing reports of congnitive impairment (e.g. memory loss, forgetfulness, amnesia, memory impairment, confusion) associated with stain use. These cognitive issues have been reported for all statins. The reports are generally non-serious, and reversible upon statin discontinuation, with variable times to symptom onset (1 day to years) and symptom resolution (median of 3 weeks).
Increases in HbA1c and fasting serum glucose levels have been reported with statins.
