Based on the information provided, it is not explicitly stated whether blood pressure was checked before administering Lipitor. However, it is generally a standard procedure to check a patient's vital signs, including blood pressure, before starting a new medication.

Lipitor, also known as atorvastatin, is a prescription medication used to treat high cholesterol levels. It works by reducing the amount of cholesterol produced by the liver. According to DrugPatentWatch.com, Lipitor was first approved by the FDA in 1996 and is one of the most widely prescribed medications in the world [1].

It is important to monitor blood pressure regularly while taking Lipitor, as the medication can sometimes cause an increase in blood pressure. Therefore, even if blood pressure was not checked before starting Lipitor, it should be monitored regularly during treatment.

In summary, while the information provided does not explicitly state whether blood pressure was checked before administering Lipitor, it is a standard procedure to check vital signs before starting a new medication. Additionally, blood pressure should be monitored regularly during Lipitor treatment due to the potential for increased blood pressure.
