Key takeaways
Niacin ER (niacin) and Atorvastatin (Lipitor) are both used to manage cholesterol levels, but they belong to different classes of medications and work in distinct ways. Niacin ER is an antilipemic and a form of vitamin B3, which helps lower "bad" LDL cholesterol and triglycerides while raising "good" HDL cholesterol. On the other hand, Atorvastatin is a statin that primarily works by blocking an enzyme in the liver responsible for making cholesterol. Niacin ER is typically taken once daily at bedtime, while Atorvastatin can be taken at any time of the day. Niacin ER can cause flushing and stomach upset, whereas Atorvastatin may lead to muscle pain and liver issues. Both medications are not recommended during pregnancy or breastfeeding. While Niacin ER is often used when statins are not effective or cause side effects, Atorvastatin is considered a first-choice medication for lowering cholesterol.
