Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood. One of the common side effects of Lipitor is drowsiness [2]. According to the Mayo Clinic, drowsiness is a less common side effect of Lipitor, but it can occur [2]. However, there is no specific information available on how long Lipitor-induced drowsiness lasts.

It is important to note that the duration and severity of side effects may vary from person to person [2]. Some people may experience drowsiness for a short period, while others may experience it for a longer time. In some cases, the side effects may persist even after discontinuing the medication [3].

If you are experiencing drowsiness or any other side effects while taking Lipitor, it is important to talk to your healthcare provider. They can provide guidance on how to manage the side effects and may recommend adjusting the dosage or switching to a different medication [2].

In conclusion, while drowsiness is a possible side effect of Lipitor, there is no specific information available on how long it lasts. The duration and severity of side effects may vary from person to person, and it is important to talk to a healthcare provider if you are experiencing any side effects while taking Lipitor.
