Medically reviewed.
Cuvrior (trientine tetrahydrochloride) is a prescription copper-chelating medication used for the maintenance treatment of adults with Wilson disease who have already been stabilized on chelation therapy. It binds excess copper and helps your body remove it through the urine. This helps maintain normal copper levels and prevent progressive liver and neurologic damage. Treatment decisions should always be individualized and guided by a healthcare professional.

ABOUT CUVRIOR TREATMENT
Cuvrior is a prescription medicine that contains trientine tetrahydrochloride. It is a copper-chelating medication. "Chelating" means it binds to copper so your body can remove it.
Cuvrior is used for the maintenance treatment of adults with Wilson disease who have already been stabilized on chelation therapy. In Wilson disease, excess copper builds up in the body.
Cuvrior comes as oral tablets. Your provider pairs it with a low-copper diet and regular monitoring, such as Liver Function Tests.
WHO CUVRIOR MAY BE SUITABLE FOR
Your healthcare provider may prescribe Cuvrior if you have Wilson disease that needs long-term maintenance therapy and you have already achieved initial copper control with chelation therapy. It may also fit if you are transitioning from another trientine formulation, such as Syprine, or if you need lifelong management of copper buildup.
Every patient's health profile is different, so there is no one-size-fits-all answer. Your provider decides whether Cuvrior fits your care plan after assessing your liver condition, copper levels, and response to earlier treatment.
ELIGIBILITY OVERVIEW
Cuvrior may be considered for adults with the following conditions or treatment goals:
Before recommending Cuvrior, healthcare providers evaluate several factors to decide whether it is an appropriate option, including:
HOW CUVRIOR CAN HELP YOUR LIVER
Cuvrior binds excess copper in the bloodstream and tissues. It forms soluble copper complexes that leave the body in the urine. This helps keep body copper stores low.
In Wilson disease, copper can build up in the liver and other organs and cause progressive liver and neurologic damage. By removing copper and helping prevent it from building up again, Cuvrior supports long-term control of the disease.
Cuvrior is not used on its own. Providers pair it with a low-copper diet and regular monitoring, such as Liver Function Tests, to track how well treatment is working.
LIVER BENEFITS
In Wilson disease, extra copper circulates in the bloodstream and settles in tissues such as the liver. Cuvrior chelates, or binds, this excess copper in both places. Once copper is bound, the body can remove it instead of storing it.
The copper complexes Cuvrior forms are soluble, which means they dissolve and can pass out of the body in the urine. This is the main way Cuvrior clears copper. Urine tests, such as 24-hour urinary copper excretion, are part of the monitoring your provider may order.
After initial chelation therapy brings copper under control, Cuvrior helps maintain reduced body copper stores. Keeping stores low over time lowers the strain that copper puts on the liver.
By helping prevent recurrent copper accumulation in the liver and other organs, Cuvrior helps guard against progressive liver and neurologic damage. This is why it supports long-term control of Wilson disease and is taken as ongoing maintenance therapy.
Cuvrior helps your body remove excess copper and keep it from building up again. It should only be started and monitored under the guidance of a qualified healthcare professional.
TREATMENT PROCESS
Cuvrior comes as oral tablets. Take it exactly as your healthcare provider prescribes, and ask your pharmacist if you have questions about your tablets.
According to the Liver Therapies Patient Guide, typical doses range from 300 to 3,000 mg a day, divided into two daily doses. The maximum recommended total daily dose is 3,000 mg a day. Your provider sets your dose based on your earlier chelation therapy, your copper levels, and how you respond.
Take Cuvrior on an empty stomach, at least 1 hour before or 2 hours after meals. Separate it from iron-containing products by at least 2 hours to help your body absorb it. Always use it exactly as your provider directs.
Cuvrior is long-term maintenance therapy, often lifelong, once you have stable copper control with earlier chelation therapy. Do not stop taking it without first talking to your healthcare provider.
Store Cuvrior at room temperature, away from moisture and heat.
Regular monitoring is recommended. It includes liver function, complete blood count, serum copper, ceruloplasmin, and 24-hour urinary copper excretion. Report any side effects or unusual symptoms to your healthcare provider.
BENEFITS AND SAFETY
Cuvrior (trientine tetrahydrochloride) helps adults with Wilson disease keep copper under control after initial chelation therapy. By removing excess copper and helping prevent it from building up again, it helps protect the liver and nervous system from copper-related injury. Results vary from person to person. Cuvrior is not a stand-alone treatment: it works best with a low-copper diet, strict adherence, and lifelong monitoring such as Liver Function Tests.
As with any medication, Cuvrior may cause side effects. Your healthcare provider will monitor your treatment and adjust your care plan as needed to balance potential benefits against any risks.
BENEFITS
Once initial chelation therapy has brought copper under control, Cuvrior helps keep copper levels controlled. It binds excess copper in the bloodstream and tissues and forms soluble complexes that leave the body in the urine. This helps maintain reduced body copper stores over time.
Wilson disease needs lifelong management, and Cuvrior is used as long-term maintenance therapy, often lifelong. By helping prevent copper from building up again in the liver and other organs, it supports steady control of the disease. Do not stop taking it without first talking to your healthcare provider.
Excess copper can cause progressive liver and neurologic damage. By helping prevent copper buildup, Cuvrior helps prevent copper-related injury to the liver and nervous system. Regular monitoring lets your care team see how well treatment is working.
Cuvrior is a tablet taken by mouth, which gives you a convenient option for maintenance treatment. Take it exactly as your provider prescribes, on an empty stomach and apart from iron-containing products.
Tell your healthcare provider about any side effects. Your provider will discuss the potential benefits and risks before treatment and will keep monitoring you, including blood counts, to support safe use.
SUPPORTING YOUR RESULTS
Cuvrior works best alongside daily habits that limit copper. The Liver Therapies Patient Guide advises a low-copper diet and strict adherence to therapy and lifelong monitoring.
Ask your care team which foods to limit and how to fit Cuvrior around meals, since it is taken on an empty stomach.

Regular monitoring is recommended during Cuvrior treatment. It includes liver function, complete blood count, serum copper, ceruloplasmin, and 24-hour urinary copper excretion. These tests show how well treatment is working and help your provider adjust your care plan. Report any side effects or unusual symptoms between visits. Ask your healthcare professional how often you need each test and what the results mean for you.
Yes. Patients taking Cuvrior are advised to follow a low-copper diet and avoid high-copper foods such as shellfish, nuts, chocolate, mushrooms, and organ meats.
