Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels and reduce the risk of heart disease [1]. While dry mouth is not listed as a common side effect of Lipitor, it is possible that it can worsen dry mouth symptoms in some individuals. According to a study published in the journal Translational Medicine, statins like Lipitor have been associated with an increased risk of xerostomia, or dry mouth [2]. The study suggests that this may be due to the effect of statins on the salivary gland function. However, it is important to note that not all individuals who take Lipitor will experience dry mouth as a side effect.

It is recommended that individuals who experience dry mouth while taking Lipitor speak with their healthcare provider. They may recommend adjusting the dosage or switching to a different medication. Additionally, there are over-the-counter products such as mouthwashes and lozenges that can help alleviate dry mouth symptoms [3].
