when to take atorvastatin morning or night

Atorvastatin, a long-acting statin, can be taken either in the morning or at night. The key to effectiveness is to take it consistently at the same time every day. Unlike shorter-acting statins that are best taken at night when cholesterol production peaks, atorvastatin stays in the body long enough (half-life about 14 hours) to work well regardless of dosing time. Therefore, choosing a time that best fits one's routine is more important than the specific time of day.
