Which of the following symptoms is a reason for seeking medical attention while taking Losartan?

Seeking medical attention while taking Losartan is especially warranted for any symptom indicative of significant liver dysfunction, such as jaundice. Jaundice is characterized by the yellowing of the skin and eyes and results from an accumulation of bilirubin due to liver problems. Losartan, an angiotensin II receptor blocker (ARB) used primarily for managing hypertension, can affect liver function in some patients, particularly those with pre-existing liver conditions.

While headaches, dry mouth, and mild dizziness are common side effects associated with many medications, including Losartan, they are generally not severe enough to necessitate immediate medical attention. Persistent mild dizziness may be monitored and reported to a healthcare provider, but it does not typically indicate a serious underlying issue like jaundice does. In contrast, jaundice requires prompt evaluation to rule out serious liver complications or other systemic issues. Therefore, recognizing jaundice as a red flag symptom underlines the importance of monitoring liver health while on medications like Losartan.
