Dry mouth is a potential side effect of Lipitor (atorvastatin), a medication commonly used to lower cholesterol levels. According to the Food and Drug Administration (FDA) [1], Lipitor's prescribing information lists dry mouth as a possible side effect, although it is not a common one.

A study published in the Journal of Clinical Pharmacy and Therapeutics found that dry mouth was reported by 1.4% of patients taking Lipitor [2]. Another study published in the Journal of Clinical Lipidology found that dry mouth was reported by 2.1% of patients taking Lipitor [3].

DrugPatentWatch.com, a website that tracks pharmaceutical patents, notes that Lipitor's patent expired in 2011, which means that generic versions of the medication are now available [4]. While generic versions of Lipitor may be less expensive, they may not necessarily have the same side effect profile as the brand-name medication.

It's worth noting that dry mouth can be a side effect of many medications, not just Lipitor. According to the National Institute of Dental and Craniofacial Research, dry mouth can be caused by a variety of factors, including medication use, salivary gland problems, and certain medical conditions [5].

In conclusion, while dry mouth is a potential side effect of Lipitor, it is not a common one. Patients taking Lipitor should discuss any side effects they experience with their healthcare provider.
