Lipitor is a medication that is used to lower cholesterol levels in the blood. The active ingredient in Lipitor is atorvastatin [2]. According to Medical News Today, atorvastatin is an oral tablet that is used to treat high cholesterol and triglyceride levels in the blood. It works by blocking an enzyme that is responsible for producing cholesterol in the liver [2].

When it comes to adjusting the dosage of Lipitor, it is important to consult with a doctor. Healthline notes that the typical starting dose of Lipitor is 10-20 mg per day, and the maximum recommended dose is 80 mg per day. However, the appropriate dosage can vary depending on the individual's medical history, current health status, and other medications they may be taking [3].

It is important to note that Lipitor is a prescription medication, and it should only be taken under the guidance of a healthcare professional. According to Drug Patent Watch, Lipitor is a brand-name medication that is manufactured by Pfizer. The patent for Lipitor expired in 2011, which means that generic versions of atorvastatin are now available [1].

In summary, if you are taking Lipitor and are considering adjusting your dosage, it is important to speak with your doctor first. The appropriate dosage can vary depending on your individual health needs, and your doctor can help determine the best course of action for you.
