The article states that some supplements may interact with medications, leading to potentially harmful side effects. Therefore, it is essential to speak with a healthcare provider before taking any new medications or supplements, including Lipitor and aspirin.

In conclusion, it is highly recommended to consult with a doctor before taking Lipitor and aspirin simultaneously. These medications can interact with each other and other medications, leading to potentially harmful side effects. It is important to speak with a healthcare provider before taking any new medications or supplements.
