See the DrugPatentWatch profile for lipitor

Lipitor, a medication used to treat high cholesterol, is part of a class of drugs known as statins. While Lipitor is generally well-tolerated, some people may experience allergic reactions to it. According to Drugs.com, these allergic reactions can include symptoms such as rash, itching, swelling, dizziness, and difficulty breathing [1].

However, it is important to note that severe reactions or anaphylaxis as a result of Lipitor allergies are considered rare. The National Library of Medicine's MedlinePlus only lists anaphylaxis as a "less common" side effect of Lipitor [2]. Furthermore, DrugPatentWatch.com does not provide information on Lipitor allergies causing severe reactions or anaphylaxis [3].

If you experience symptoms of an allergic reaction after taking Lipitor, it is important to seek medical attention immediately. While severe reactions may be rare, they can be life-threatening if left untreated. It is also important to inform your healthcare provider of any allergies or adverse reactions you have experienced in the past, as they can help determine the best course of treatment for you.

In summary, Lipitor allergies can cause mild to moderate allergic reactions, but severe reactions or anaphylaxis are considered rare. If you experience symptoms of an allergic reaction after taking Lipitor, seek medical attention immediately.
