The most serious side effect of losartan, an angiotensin II receptor blocker (ARB) used to treat high blood pressure, is the potential for causing kidney problems or worsening existing kidney issues. In rare cases, it can also lead to a severe allergic reaction, characterized by symptoms such as swelling of the face, lips, or throat, which requires immediate medical attention. It's important for patients to discuss their medical history and any concerns with their healthcare provider before starting losartan.
