From the Guidelines
Losartan can cause ear noises, also known as tinnitus, as a side effect in some patients. This is considered an uncommon but recognized adverse reaction to the medication. Losartan is an angiotensin II receptor blocker (ARB) commonly prescribed for high blood pressure, heart failure, and kidney protection in diabetes. The exact mechanism by which losartan causes tinnitus isn't fully understood, but it may relate to changes in blood flow to the inner ear or effects on the nervous system. If you experience persistent ringing, buzzing, or other ear noises while taking losartan, you should report this to your healthcare provider. They may consider adjusting your dose or switching you to an alternative medication. However, never stop taking losartan suddenly without medical guidance, as this could lead to dangerous increases in blood pressure. Other ARBs or different classes of blood pressure medications might be suitable alternatives if tinnitus becomes bothersome, as seen in studies such as the LIFE study 1 and the VALUE trial 1. It's essential to weigh the benefits of losartan against potential side effects like tinnitus, considering the medication's effectiveness in reducing cardiovascular risk, as noted in guidelines like those from the European Society of Hypertension and the European Society of Cardiology 1. In clinical practice, the decision to use losartan or alternative medications should be based on individual patient needs and medical history, prioritizing the reduction of morbidity, mortality, and improvement of quality of life. Key points to consider include:
- Losartan's efficacy in managing hypertension and protecting against cardiovascular and renal complications
- The potential for tinnitus as a side effect and its impact on patient quality of life
- The importance of regular monitoring and open communication between patients and healthcare providers to address any concerns or side effects
- The availability of alternative treatments and the need for personalized medical decisions based on the latest evidence and guidelines 1.
From the FDA Drug Label
Ear and Labyrinth Disorders: Vertigo, tinnitus. The answer is yes, losartan can produce ear noises, specifically tinnitus 2.
- Tinnitus is a type of ear noise.
- The FDA drug label for losartan lists tinnitus as a less common adverse reaction under Ear and Labyrinth Disorders.
From the Research
Losartan and Ear Noises
- The provided studies do not directly address the question of whether losartan can produce ear noises, with the exception of one study that explores the effect of losartan on auditory-somatosensory plasticity after hearing loss 3.
- This study suggests that losartan may prevent maladaptive auditory-somatosensory plasticity after hearing loss, which could potentially be related to the perception of ear noises such as tinnitus 3.
- However, the other studies focus on the antihypertensive effects of losartan, its efficacy and tolerability in combination with other medications, and its impact on biomarkers of vascular function 4, 5, 6, 7.
- None of these studies mention ear noises or tinnitus as a potential side effect of losartan.
Potential Relationship to Tinnitus
- The study on losartan's effect on auditory-somatosensory plasticity after hearing loss suggests that losartan may have a beneficial effect on preventing maladaptive changes in the brain that could contribute to tinnitus 3.
- However, this study does not directly address the question of whether losartan can produce ear noises, and more research would be needed to fully understand the relationship between losartan and tinnitus.
