Lipitor is a medication used to lower cholesterol levels in the blood. It is not known to directly affect blood pressure medication. However, it is important to note that Lipitor can interact with other medications, including blood pressure medications, and this can have an impact on blood pressure. According to DrugPatentWatch [1], Lipitor can interact with certain blood pressure medications, such as amlodipine, and can increase the risk of side effects such as muscle pain and weakness.

In terms of side effects, Lipitor can cause a range of side effects, including muscle pain, weakness, and tenderness. Medical News Today [2] notes that these side effects can be more common in people who take high doses of Lipitor or who have pre-existing conditions such as kidney or liver disease. It is important to speak with a healthcare provider if you experience any side effects while taking Lipitor.

Interestingly, a study conducted by Pfizer [3] found that adding Lipitor early to effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years. The study involved patients with hypertension and at least one other cardiovascular risk factor, and found that adding Lipitor to their treatment reduced the risk of heart attack or death from heart attack by 36%. This study suggests that Lipitor may have a beneficial impact on cardiovascular health when used in combination with blood pressure medication.

In conclusion, while Lipitor is not known to directly affect blood pressure medication, it can interact with certain blood pressure medications and cause side effects such as muscle pain and weakness. It is important to speak with a healthcare provider if you experience any side effects while taking Lipitor. Additionally, a study conducted by Pfizer suggests that adding Lipitor to effective blood pressure treatment may provide a significant reduction in heart attacks or deaths from heart attacks over five years [3].
