Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur due to various reasons, including medication use. Lipitor (atorvastatin) is a medication used to treat high cholesterol levels. According to the sources provided, anaphylaxis caused by Lipitor is a rare side effect.
The first source, Drug Patent Watch [1], provides information on the adverse effects of Lipitor. The report states that anaphylaxis is a rare side effect of Lipitor, occurring in less than 0.1% of patients. However, it is essential to note that this data is based on clinical trials and may not reflect the actual occurrence of anaphylaxis in the general population.
The second source, NHS [2], provides a list of possible side effects of atorvastatin, including allergic reactions such as rash, hives, and swelling of the face, lips, tongue, and throat. The website advises patients to seek immediate medical attention if they experience symptoms of an allergic reaction.
The third source, a study published in the Journal of Pharmacology and Pharmacotherapeutics [3], also confirms that anaphylaxis caused by atorvastatin is a rare occurrence. The study analyzed adverse drug reactions reported to the Pharmacovigilance Program of India and found that out of 47,708 reports, only one case of anaphylaxis was attributed to atorvastatin.
In conclusion, anaphylaxis caused by Lipitor is a rare side effect, occurring in less than 0.1% of patients. Patients taking Lipitor should be aware of the possible allergic reactions associated with the medication and seek immediate medical attention if they experience any symptoms. It is essential to note that the data provided is based on clinical trials and may not reflect the actual occurrence of anaphylaxis in the general population. Patients should always consult their healthcare provider for any concerns or questions regarding their medication.
