Lipitor is a medication that is commonly prescribed to lower cholesterol levels in the body. According to the NHS, Lipitor should be taken once a day, at the same time each day, with or without food [3]. However, it is important to note that the timing of Lipitor intake may affect its efficacy. According to Drugs.com, taking Lipitor at night may be more effective in lowering cholesterol levels [2]. This is because the body produces more cholesterol at night, and Lipitor is most effective when taken during this time [2]. It is recommended to take Lipitor at bedtime, as it may help to reduce the risk of side effects such as muscle pain [2].

Drugpatentwatch provides information on the patent status of Lipitor, but does not provide information on the timing of Lipitor intake before bedtime [1].

In conclusion, Lipitor should be taken once a day, at the same time each day, with or without food [3]. However, taking Lipitor at night may be more effective in lowering cholesterol levels, and it is recommended to take Lipitor at bedtime to reduce the risk of side effects such as muscle pain [2]. It is important to consult with a healthcare provider regarding the appropriate timing of Lipitor intake.
