Know that treatment options are available


If you are diagnosed with hATTR amyloidosis, treatments are available that address the underlying cause of the disease. These therapies can help by decreasing the amount of TTR protein that’s made in the body. There are also treatments that bind to TTR proteins and help prevent them from forming clusters.

Liver and/or heart transplant is also an option for some patients who meet certain eligibility criteria.

Since the symptoms of hATTR amyloidosis can worsen over time, managing symptoms is an ongoing process. Doctors may prescribe medication to help manage some of the symptoms that may reduce the daily impact on patients. Additional treatment options for hATTR amyloidosis are currently being researched.
