Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood [1]. Amlodipine is a medication used to treat high blood pressure [2]. These two medications can be prescribed together to treat high blood pressure and high cholesterol levels. However, there are potential side effects that may occur when taking these medications together.

According to the Mayo Clinic, amlodipine and atorvastatin may interact with each other and cause side effects such as muscle pain or weakness, liver problems, and an increased risk of developing diabetes [2]. Patients should inform their doctor of any muscle pain, tenderness, or weakness they experience while taking these medications.

Additionally, patients taking atorvastatin should avoid consuming grapefruit or grapefruit juice as it can increase the risk of side effects [3]. Grapefruit can increase the level of atorvastatin in the blood, leading to a higher risk of side effects such as muscle pain or weakness.

In conclusion, taking Lipitor and blood pressure medications such as amlodipine together can cause potential side effects such as muscle pain or weakness, liver problems, and an increased risk of developing diabetes. Patients should inform their doctor of any symptoms they experience while taking these medications. Patients taking Lipitor should also avoid consuming grapefruit or grapefruit juice to reduce the risk of side effects.
