Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. Atorvastatin is available as a generic medication, and like all drugs, it may have side effects.

According to Everyday Health [3], the most common side effects of atorvastatin include headache, muscle pain, weakness, stomach pain, and nausea. These side effects are usually mild and go away on their own. However, if they persist or become severe, it is important to contact a healthcare provider.

More serious side effects of atorvastatin can include liver problems, muscle damage, and an increased risk of developing type 2 diabetes. Medical News Today [2] states that these side effects are rare and typically occur in people who take high doses of atorvastatin or have other risk factors. It is important to talk to a doctor about any concerns or questions regarding the use of atorvastatin.

Drug Patent Watch [1] notes that generic versions of atorvastatin have been available since 2011, and that the FDA has determined that these generics are equivalent to the brand-name Lipitor in terms of safety and effectiveness. However, it is important to note that different generic versions of atorvastatin may have different inactive ingredients, which can affect how the drug is absorbed and metabolized in the body.

In summary, while atorvastatin (the generic version of Lipitor) may have side effects, these are usually mild and go away on their own. More serious side effects are rare and typically occur in people who take high doses of the drug or have other risk factors. It is important to talk to a healthcare provider about any concerns or questions regarding the use of atorvastatin.
