Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels in the blood. According to Drug Patent Watch [1], the patent for Lipitor expired in 2011, which means that it is now available as a generic drug.

While Lipitor is generally considered safe and effective, it can cause side effects in some people. The Mayo Clinic [2] reports that common side effects of statins, including Lipitor, can include muscle pain and damage, liver damage, digestive problems, and increased blood sugar levels. More serious side effects, such as rhabdomyolysis (a condition that causes muscle breakdown) and an increased risk of diabetes, are rare but possible.

If you are still experiencing symptoms from Lipitor, it is important to talk to your doctor. They may be able to adjust your dosage or switch you to a different medication. SingleCare [3] notes that some people may be more susceptible to side effects from Lipitor, such as those with liver or kidney problems, and those who are older or taking other medications.

In conclusion, Lipitor is a medication used to treat high cholesterol levels that can cause side effects in some people. If you are still experiencing symptoms from Lipitor, it is important to talk to your doctor about your options. They may be able to adjust your dosage or switch you to a different medication.
