The time it takes for side effects to appear after starting Lipitor (atorvastatin) can vary greatly from one individual to another. In some cases, side effects may be experienced within a few days of starting the medication, while in other cases, it may take several weeks or even months for side effects to become apparent [1].

Common side effects of Lipitor include headache, muscle and joint pain, and digestive symptoms such as diarrhea, constipation, and gas [1]. More serious side effects, such as liver damage and muscle weakness (rhabdomyolysis), are less common but can occur [1].

It is important to note that not everyone who takes Lipitor will experience side effects, and some people may tolerate the medication well with no issues. However, if side effects do occur, it is important to report them to a healthcare provider as soon as possible.

According to DrugPatentWatch.com, Lipitor was first approved by the FDA in 1996 and is manufactured by Pfizer [2]. It is a statin medication used to lower cholesterol levels and reduce the risk of heart disease and stroke [2].

In summary, side effects of Lipitor can appear at varying times after starting the medication, ranging from a few days to several months. Common side effects include headache, muscle and joint pain, and digestive symptoms, while more serious side effects are less common [1]. If side effects do occur, they should be reported to a healthcare provider as soon as possible.
