Lipitor, also known as Atorvastatin, is a prescription medication used to treat high cholesterol levels and reduce the risk of heart attack and stroke. According to the sources provided, there is no specific time of day that is recommended for taking Lipitor. It can be taken at any time of the day, with or without food, but it is important to take it at the same time every day to maintain a consistent level in the bloodstream [2].

However, it is essential to follow the instructions of the prescribing doctor or the medication label. In some cases, the doctor may recommend taking Lipitor at a particular time of day to maximize its effectiveness and minimize potential side effects [3].

It is also important to note that Lipitor is a long-term medication that requires regular use to maintain its effectiveness. Missing a dose can reduce its effectiveness and increase the risk of heart attack and stroke. If a dose is missed, it should be taken as soon as possible, unless it is almost time for the next dose. In that case, the missed dose should be skipped and the regular dosing schedule resumed [1].

In conclusion, there is no specific time of day recommended for taking Lipitor, but it is important to take it at the same time every day and follow the instructions of the prescribing doctor or medication label. It is also essential to take Lipitor regularly to maintain its effectiveness and reduce the risk of heart attack and stroke.
