Drugs Home > Side Effects of Atorvastatin

Some of the most common atorvastatin side effects are headache, diarrhea, and muscle pain. Other common problems associated with the medication include joint pain and unexplained rash. Most side effects -- if they occur -- are minor and easily treated, but some are potentially serious and should be reported to your healthcare provider.

Side Effects of Atorvastatin: An Introduction

As with any medicine, side effects can occur with atorvastatin calcium (Lipitor®). However, not everyone who takes the drug will have problems. In fact, most people tolerate it well.
 
If people do develop side effects, in most cases, they are minor, meaning they require no treatment or are easily treated by you or your healthcare provider. In research studies, less than 2 percent of people taking atorvastatin stopped treatment because of these problems.
 
If you experience unexplained muscle pain, tenderness, or weakness, especially if accompanied by a fever or if you feel ill, it is important to contact your healthcare provider immediately.
 
(This article covers many, but not all, of the possible side effects with atorvastatin. Your healthcare provider can discuss a more complete list with you.)
