Hello, Jane Hart!
Thank you for your message.
Losartan is used to treat high blood pressure (hypertension). It's also used to lower the risk of stroke in certain people with heart disease or to slow long-term kidney damage in people with type 2 diabetes who also have high blood pressure. If you feel Losartan is worsening the tremors, speak to your doctor about your concerns.
For the benefit of our readers, essential tremor is a brain disorder that causes a part of your body to shake. The hands and forearms are the most commonly affected areas, but other parts of the body can also be affected.
There’s no cure for essential tremor, but there are treatments that may help relieve your symptoms. If your symptoms are severe and interfering with your normal activities, treatment options can include medications, therapies, and surgery.

Your doctor can discuss these options with you in more detail.
