Lipitor and Muscle Aches: Things to Remember

For people taking Lipitor, muscle aches can be a common problem, especially during the initial months of treatment or when the Lipitor dosage is increased. Unfortunately, it is not possible for your healthcare provider to know whether you will develop this side effect if you have never taken Lipitor. If muscle aches do become a problem while you are taking Lipitor, talk with your healthcare provider. He or she may be able to give you other suggestions for dealing with muscle aches. If the muscle aches continue, he or she may recommend adjusting the Lipitor dosage or switching to another cholesterol medication.
 
Also, if muscle aches, weakness, pain, or tenderness occur, accompanied by a fever or feeling of sickness, it can mean there is a serious problem. Call your healthcare provider immediately.
