Based on the available information, it is recommended to inform your healthcare provider about any herbal use while taking Lipitor (atorvastatin), as certain herbal supplements can interact with Lipitor and affect its efficacy or increase the risk of side effects [3]. However, specific guidance on adjusting Lipitor doses with herbal use is not provided in the sources. Therefore, it is essential to consult with a healthcare professional for personalized advice [1][2][3].
