Based on the information provided, I cannot specify exactly when you first noticed Lipitor side effects. However, I can provide some general information about Lipitor and its potential side effects.

Lipitor, also known as atorvastatin, is a statin medication used to treat high cholesterol and prevent cardiovascular disease [1]. It was first approved by the US Food and Drug Administration (FDA) in December 1996 [1]. As with any medication, Lipitor can cause side effects, which can vary in severity and frequency among individuals.

Common side effects of Lipitor include muscle pain, joint pain, diarrhea, and minor memory problems [2]. In rare cases, Lipitor has been associated with more severe side effects, such as liver damage, muscle damage (rhabdomyolysis), and increased blood sugar levels [2].

If you have experienced side effects while taking Lipitor, it is essential to consult your healthcare provider for advice and appropriate action.
