Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. According to the sources provided, there is no clear evidence that Lipitor can worsen low sodium symptoms.

Low sodium levels, also known as hyponatremia, can be caused by various factors such as medication side effects, dehydration, and certain medical conditions. In severe cases, hyponatremia can lead to confusion, seizures, and coma [2].

The clinical reference source, Medscape, lists hyponatremia as a possible side effect of atorvastatin, but it is not a common one [2]. Additionally, the drug patent watch website does not mention hyponatremia as a known side effect of Lipitor [1].

A recent study published in the Circulation Research Journal investigated the effects of atorvastatin on sodium channels in the heart. The study found that atorvastatin did not significantly affect the function of sodium channels [3].

Overall, while hyponatremia is a potential side effect of atorvastatin, there is no clear evidence that Lipitor specifically can worsen low sodium symptoms. However, if you are experiencing low sodium symptoms, it is important to speak with your healthcare provider to determine the underlying cause and appropriate treatment.
