Lipitor is a medication used to lower cholesterol levels in the body [2]. According to Medscape, the usual starting dose for Lipitor is 10-20 mg once daily, with a maximum dose of 80 mg once daily [3]. The dosage can be adjusted based on individual needs, such as age, gender, and other medical conditions. Weight loss can also be a factor in determining the appropriate dosage for Lipitor.

While the sources do not provide specific information on whether Lipitor dosage should be adjusted after weight loss, it is known that weight loss can have a positive impact on cholesterol levels in the body [2]. Therefore, it is possible that a person who has experienced weight loss may require a lower dosage of Lipitor to maintain healthy cholesterol levels. However, any changes to medication dosage should be made in consultation with a healthcare provider.

In conclusion, weight loss can have a positive impact on cholesterol levels, which may affect the appropriate dosage of Lipitor for an individual. However, any changes to medication dosage should be made in consultation with a healthcare provider.
