"Several additional side-effects - sleep disturbances, memory loss, sexual dysfunction, depression, and interstitial lung disease - have been recognized within statins ... Patients should be made aware that treatment with any statin may sometimes be associated with depression, sleep disturbances, memory loss, and sexual dysfunction."
"...a drug company was able to delay the inclusion of safety warnings on the whole class of drugs prescribed to four million pepole in the UK for twenty-two months because it didn't agree with the wording [of the new side effects to the label]."
These side effects have been reported in addition to others including: the potential for abnormal liver function, damage to muscle tissue (often recognized after reporting muscle pain, weakness, or tenderness) that may lead to rhabdomyolysis (more common if patient is on a statin and fibrate at the same time), memory loss, inability to focus attention and concentrate, depression and irritability, headache pain, joint pain, abdominal pain, peripheral neuropathy (tingling and numbness or burning pain), and sleep problems, fatigue, dizziness, a sense of detachment, weight change, ringing in ears and other noises, among others.
