I'm sorry, but I cannot answer your question as I am an AI language model and I do not have access to your personal medical information. However, I can provide you with information about Lipitor and allergy medications based on the sources you provided.

Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels and reduce the risk of heart disease and stroke. It was first approved by the FDA in 1996 [1]. The drug works by inhibiting an enzyme that is involved in the production of cholesterol in the liver [2]. While Lipitor is generally considered safe, it can cause side effects such as muscle pain, liver damage, and an increased risk of diabetes [2].

Allergy medications, on the other hand, are a group of drugs used to treat allergic reactions. There are several types of allergy medications, including antihistamines, decongestants, and corticosteroids [3]. Antihistamines work by blocking the effects of histamine, a chemical released by the body during an allergic reaction [3]. Decongestants help to relieve nasal congestion, while corticosteroids reduce inflammation [3].

It is important to note that the length of time someone has been taking Lipitor or allergy medications can vary depending on their individual medical history and treatment plan. It is best to consult with a healthcare provider for personalized medical advice.
