I'm not a doctor, but I can provide some general information about Lipitor and muscle fatigue.

Lipitor (atorvastatin) is a medication used to treat high cholesterol levels. It belongs to a class of medications called statins, which work by reducing the production of cholesterol in the liver. While Lipitor is generally well-tolerated, it can cause muscle fatigue as a side effect in some individuals.

According to the prescribing information for Lipitor [1], muscle fatigue is listed as a potential side effect, along with other symptoms such as muscle weakness, pain, or tenderness. However, it's important to note that muscle fatigue can also be caused by other factors, such as underlying medical conditions, physical inactivity, or other medications.

If you're experiencing muscle fatigue while taking Lipitor, it's essential to talk to your doctor about the symptoms. They may recommend adjusting your dosage or switching to a different medication. In some cases, muscle fatigue may be a sign of a more serious condition, such as rhabdomyolysis, which is a rare but potentially life-threatening condition that can occur with statin use [2].

It's also important to note that the risk of muscle fatigue with Lipitor may be higher in certain individuals, such as those with pre-existing muscle disorders or those who are taking other medications that can interact with statins [3].

In terms of how long you've been taking Lipitor for muscle fatigue, it's difficult to say without more information. If you're experiencing muscle fatigue while taking Lipitor, it's essential to talk to your doctor about the symptoms and any potential underlying causes.
