What time of day to take lipitor?

Bottom line, you need to take it forever. If you stop, your cholesterol will rise back to pre-treatment levels....exposing you to risk of MI and Stroke.

You should not stop taking Lipitor without consulting your doctor. However, one of the warnings for Lipitor is that if you experience "unexplained muscle pain or weakness," you should get immediate medical attention, because it may be a symptom of a rare but serious side effect.
