Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor is not known to have any interactions with antidepressants. However, a study published in the Journal of Clinical Psychopharmacology [2] suggests that some statins, including atorvastatin, may increase the risk of developing depression in patients who are already taking antidepressants.

The study analyzed data from over 26,000 patients who were taking antidepressants and found that those who were also taking statins had a higher incidence of depression compared to those who were not taking statins. The study did not specifically look at Lipitor, but atorvastatin is one of the most commonly prescribed statins in the United States [1].

While Lipitor may not directly increase the side effects of antidepressants, some antidepressants can cause nightmares and disturbing dreams [3]. This side effect can be particularly troubling for patients who are already struggling with depression or anxiety. Patients who experience these side effects should talk to their doctor about adjusting their medication regimen.

In conclusion, while Lipitor is not known to have any interactions with antidepressants, a study suggests that some statins, including atorvastatin, may increase the risk of developing depression in patients who are already taking antidepressants. Additionally, some antidepressants can cause nightmares and disturbing dreams, which can be exacerbated by Lipitor. Patients who are experiencing these side effects should talk to their doctor about adjusting their medication regimen.
