* Gemfibrozil, a cholesterol-lowering medication, can increase the levels of Lipitor in the body, increasing the risk of side effects [1].
* Cyclosporine, a medication used to suppress the immune system, can increase the levels of Lipitor in the body, increasing the risk of side effects [1].

St. John's Wort can interact with a variety of medications, including:

* Selective serotonin reuptake inhibitors (SSRIs), a type of antidepressant, can increase the risk of serotonin syndrome when taken with St. John's Wort [2].
* Warfarin, a blood thinner, can decrease the effectiveness of warfarin when taken with St. John's Wort [2].
