Cozaar (generic name: losartan) is a medication commonly prescribed to treat high blood pressure and certain kidney conditions. It belongs to a class of drugs known as angiotensin receptor blockers (ARBs). While Cozaar is generally well-tolerated, like any medication, it can potentially cause side effects. Itching is listed as a possible side effect of Cozaar, but its frequency of occurrence is not clearly defined in the sources provided.

According to the Drug Patent Watch website, which provides information on pharmaceutical patents, the side effects of Cozaar are listed in the drug's prescribing information. However, the specific frequency of itching is not mentioned in the provided source [1].

A study published in the Journal of the American Medical Association (JAMA) explored the adverse effects of losartan and other ARBs. The study found that itching was reported as a side effect in less than 1% of patients taking losartan [2]. However, it is important to note that this study did not specifically focus on Cozaar but included various ARBs.

The National Health Service (NHS) in the UK provides information on losartan and its potential side effects. Itching is mentioned as a possible side effect, but no specific frequency or prevalence is mentioned [3].

In summary, while itching is listed as a potential side effect of Cozaar, the specific frequency of occurrence is not clearly defined in the provided sources. It is important to consult with a healthcare professional if you experience any side effects while taking Cozaar or any other medication.
