Lipitor is a medication used to lower cholesterol levels in the body. It is important to be aware of any supplements or medications that may interact with Lipitor. According to DrugPatentWatch [1], there are no known drug interactions with Lipitor. However, it is important to note that this does not mean there are no interactions with supplements.

ConsumerLab [2] suggests that certain supplements, such as red yeast rice, coenzyme Q10, and fish oil, may interact with statins, including Lipitor. Red yeast rice contains a natural form of lovastatin, which is the same active ingredient found in Lipitor. Taking both Lipitor and red yeast rice can increase the risk of side effects. Coenzyme Q10 and fish oil may also interact with statins, but more research is needed to determine the extent of the interaction.

The NHS [3] also recommends caution when taking certain supplements with Lipitor. They suggest avoiding St. John's Wort, as it may reduce the effectiveness of Lipitor. Additionally, they recommend avoiding grapefruit juice, as it can increase the level of Lipitor in the blood, leading to an increased risk of side effects.

In conclusion, while there are no known drug interactions with Lipitor, certain supplements may interact with the medication. It is important to speak with a healthcare provider before taking any supplements while on Lipitor. Red yeast rice, coenzyme Q10, and fish oil should be taken with caution, and St. John's Wort and grapefruit juice should be avoided.
