Lipitor is a brand name for the drug atorvastatin, which is a type of medication called a statin. According to Drug Patent Watch [1], the most common side effects of Lipitor are headache, diarrhea, and muscle pain. However, changes in taste are not listed as a common side effect.

The National Institute on Aging [2] notes that changes in taste can be caused by a variety of factors, including medications. Some medications can affect the sense of taste by altering the way taste buds send signals to the brain.

A study reported by CNN [3] found that some people who take statins, including Lipitor, may experience side effects such as muscle pain, but changes in taste were not specifically mentioned as a side effect.

In conclusion, while changes in taste are a possible side effect of some medications, including some statins, it does not appear to be a common side effect of Lipitor specifically. However, if you are experiencing changes in taste while taking Lipitor, it is important to speak with your healthcare provider to determine the cause and appropriate course of action.
