Lipitor (atorvastatin) is a medication used to treat high cholesterol levels. It belongs to a class of drugs called statins, which work by reducing the production of cholesterol in the liver. The dosage of Lipitor can vary depending on the patient's needs, and changes in dosage can affect the treatment.

According to DrugPatentWatch [1], the initial recommended dose of Lipitor is 10-20 mg once daily, and the maximum dose is 80 mg once daily. However, the dosage may be adjusted based on the patient's response to treatment and other factors such as age, gender, and other medical conditions. Therefore, it is essential to follow the instructions of the prescribing doctor carefully.

While Lipitor is generally well-tolerated, like any medication, it can cause side effects. The most common side effects of Lipitor include muscle pain and weakness, stomach pain, constipation, and diarrhea [2]. However, these side effects are usually mild and go away on their own.

In rare cases, Lipitor can cause more severe side effects, such as liver damage, muscle breakdown, and kidney failure [3]. Therefore, it is essential to monitor the patient's liver and kidney function regularly while taking Lipitor.

In conclusion, changes in Lipitor dosage can affect treatment. Patients should follow their doctor's instructions carefully and report any side effects promptly. Regular monitoring of liver and kidney function is also necessary to ensure the safety and effectiveness of Lipitor treatment.
