Lipitor (atorvastatin) is a medication used to lower cholesterol levels, while antidepressants are used to treat depression and other mental health conditions. According to the sources provided, there is limited information on the potential side effects of combining Lipitor and antidepressants.

DrugPatentWatch [1] provides information on the patent status of Lipitor, but does not mention any side effects or interactions with antidepressants.

A study published in the US National Library of Medicine [2] investigated the potential interactions between atorvastatin (Lipitor) and several antidepressants. The study found that there was a potential for drug interactions between atorvastatin and some antidepressants, including fluoxetine (Prozac) and sertraline (Zoloft). The study suggests that close monitoring of patients is necessary when combining these medications.

NBC News [3] reported on Pfizer's COVID pills, which are unrelated to Lipitor and antidepressants. Therefore, this source is not relevant to the question.

In conclusion, while there is limited information on the potential side effects of combining Lipitor and antidepressants, a study suggests that there may be a potential for drug interactions. It is important for patients to discuss any concerns with their healthcare provider and closely monitor any side effects when taking these medications together.
