Lipitor, a medication commonly prescribed to help lower cholesterol levels, is generally considered safe and effective when used as directed. However, like all medications, it can have side effects. According to the Lipitor medication guide provided by the FDA, some common side effects include:

1. Muscle pain
2. Liver problems
3. Digestive issues such as diarrhea, constipation, and gas
4. Sore throat
5. Nosebleeds
6. Memory problems
7. Dizziness
8. Cough

In rare cases, Lipitor has been associated with more serious side effects, such as:

1. Rhabdomyolysis, a serious breakdown of muscle tissue that can lead to kidney failure
2. Liver damage
3. Increased blood sugar levels

It is important to note that these serious side effects are not common, and the risk of experiencing them is generally low. However, if you experience any of these symptoms while taking Lipitor, you should contact your healthcare provider immediately.

Additionally, Lipitor may interact with other medications, so it is important to inform your healthcare provider of all medications you are currently taking.

According to DrugPatentWatch.com, Lipitor is a statin medication that was first approved by the FDA in 1996 and is currently manufactured by Pfizer. The drug's patent expired in 2011, which has led to the availability of generic versions of the medication.

In summary, while Lipitor can have side effects, they are generally mild and uncommon. However, if you experience any severe or persistent symptoms while taking Lipitor, you should contact your healthcare provider immediately.
