Lipitor is a medication used to lower cholesterol levels in the body. It belongs to a class of drugs called statins and is available only with a prescription [3]. The drug works by blocking the enzyme that produces cholesterol in the liver [1].

While taking supplements along with Lipitor, one should be careful as some supplements can interact with the drug and cause adverse effects. For instance, taking large amounts of grapefruit juice or grapefruit supplements can increase the risk of side effects from Lipitor [2]. This is because grapefruit juice can increase the level of Lipitor in the blood, which can lead to muscle pain, liver damage, and kidney failure [2]. Therefore, it is recommended to avoid grapefruit juice or supplements while taking Lipitor [2].

Similarly, taking supplements containing niacin or vitamin B3 along with Lipitor can increase the risk of muscle damage [2]. Therefore, it is important to consult a doctor before taking any supplements along with Lipitor.

Some common side effects of Lipitor include muscle pain, diarrhea, constipation, and nausea [3]. However, serious side effects such as liver damage, muscle breakdown, and kidney failure are rare [3]. If a person experiences any of these serious side effects, they should seek medical attention immediately.

In conclusion, while taking Lipitor, it is important to be cautious about taking supplements that may interact with the drug and cause adverse effects. Grapefruit juice and supplements containing niacin or vitamin B3 should be avoided, and it is recommended to consult a doctor before taking any other supplements along with Lipitor [2].
