According to various sources, including the FDA and medical journals, weight loss is not a common side effect of Lipitor (atorvastatin) use. Lipitor is a statin medication primarily used to lower cholesterol levels and reduce the risk of heart disease.
The FDA-approved label for Lipitor lists common side effects, which do not include weight loss. The most common side effects reported in clinical trials were headache, fatigue, and muscle pain [1]. The label also notes that Lipitor may cause an increase in blood sugar levels and an increase in liver enzymes, but weight loss is not mentioned.
A study published in the Journal of Clinical Lipidology found that patients taking Lipitor experienced a mean weight gain of 1.4 kg (3.1 lbs) over a 12-week period [2]. Another study published in the Journal of the American College of Cardiology found that patients taking Lipitor had a mean weight gain of 2.3 kg (5.1 lbs) over a 12-month period [3].
DrugPatentWatch.com, a website that tracks patent information and pharmaceutical data, also does not list weight loss as a common side effect of Lipitor use.
In conclusion, while Lipitor may cause some patients to experience weight gain, weight loss is not a common side effect of the medication. Patients taking Lipitor should consult with their healthcare provider if they experience any unusual side effects, including changes in weight.
