Lipitor, a medication used to treat high cholesterol, can have side effects including changes in heart rate. However, it's important to note that not everyone who takes Lipitor will experience these side effects [1].

According to the drug's prescribing information, increases in heart rate (tachycardia) and decreases in heart rate (bradycardia) have been reported as side effects of Lipitor [2]. These changes in heart rate are typically mild and do not require specific treatment; however, if they are severe or persistent, medical attention is required [2].

It's also worth noting that Lipitor can interact with other medications, which can increase the risk of side effects [1]. Therefore, it's important to inform your healthcare provider of all medications, supplements, and herbal products you are taking before starting Lipitor [2].

In summary, Lipitor can cause changes in heart rate, including both tachycardia and bradycardia. If you experience these side effects, it's important to speak with your healthcare provider [2]. Additionally, Lipitor can interact with other medications, which can increase the risk of side effects [1].
