Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor is available in tablet form in various strengths, including 10mg, 20mg, 40mg, and 80mg. The recommended starting dose of Lipitor is usually 10-20mg per day, which can be adjusted based on the individual's response to the medication and their cholesterol levels.

The dosage of Lipitor can be adjusted gradually based on the patient's response to the medication and their cholesterol levels. The goal is to find the lowest effective dose that will effectively lower the patient's cholesterol levels without causing any adverse effects. According to UpToDate [2], the dosage of Lipitor can be increased by 10-20mg every 2-4 weeks until the desired cholesterol levels are achieved. Similarly, if the patient experiences adverse effects, the dosage can be decreased gradually until the side effects subside.

It is important to note that Lipitor should not be stopped abruptly without consulting a healthcare provider. According to UnityPoint Health [3], stopping statins suddenly can cause a rebound effect, leading to a sudden increase in cholesterol levels. Therefore, if a patient wishes to stop taking Lipitor, they should discuss it with their healthcare provider, who may gradually decrease the dosage over time.

In conclusion, the dosage of Lipitor can be adjusted gradually based on the individual's response to the medication and their cholesterol levels. The goal is to find the lowest effective dose that will effectively lower the patient's cholesterol levels without causing any adverse effects. However, Lipitor should not be stopped abruptly without consulting a healthcare provider.
