Based on the information available, the time it takes for side effects to emerge after starting Lipitor (atorvastatin) can vary greatly from one individual to another. Lipitor is a prescription medication used to treat high cholesterol levels, and it belongs to a class of drugs called statins [1].

Common side effects of Lipitor may include headache, muscle and joint pain, and digestive symptoms such as diarrhea, constipation, and gas [2]. However, it is essential to note that not everyone who takes Lipitor will experience side effects, and some people may not experience any at all.

According to DrugPatentWatch.com, Lipitor was first approved by the FDA in December 1996, and its patent expired in November 2011 [3]. Since then, several generic versions of atorvastatin have become available on the market.

It is important to remember that while side effects can emerge soon after starting a medication, they can also develop over time. Therefore, it is crucial to monitor any new symptoms or changes in your body while taking Lipitor or any other medication. If you experience any side effects that concern you or persist for an extended period, it is recommended to consult your healthcare provider [4].

In summary, the time it takes for side effects to emerge after starting Lipitor can vary, and not everyone who takes the medication will experience side effects. Common side effects of Lipitor include headache, muscle and joint pain, and digestive symptoms. If you experience any side effects that concern you or persist for an extended period, consult your healthcare provider.
