According to the sources provided, there is no recommended waiting period for Lipitor users.

Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. It is a prescription drug that was first approved by the FDA in 1996 [1].

A study published in JAMA Network Open in 2021 examined the safety of atorvastatin use in older adults and found that there was no significant increase in the risk of adverse events, including muscle-related side effects, in patients who took atorvastatin compared to those who did not [2].

Another study published in the Journal of Clinical Lipidology in 2021 found that atorvastatin was effective in reducing low-density lipoprotein cholesterol levels in patients with familial hypercholesterolemia, a genetic condition that causes high cholesterol levels [3].

Overall, while Lipitor may cause side effects in some users, there is no recommended waiting period for its use. It is important for patients to discuss any concerns or questions about Lipitor with their healthcare provider.
