Cufence is a medicine used for the treatment of Wilson’s disease in adults, adolescents and children aged 5 years or older. It is for use by patients who cannot take another medicine, D-Penicillamine, because of side effects.
Cufence contains the active substance trientine, a copper-chelating agent that is used to remove excess of copper from the body. Cufence attaches to the copper, which is then passed from the body.
If you are allergic to trientine or any of the other ingredients of this medicine (listed in section 6).
Signs of an allergic reaction include rash, itching, swelling of the face, fainting and breathing problems.
Your doctor will need to regularly check for symptoms of the disease and copper levels in your blood and urine. Regular monitoring is especially important at the start of your treatment or when your dose is changed, in growing children and pregnant women to ensure that copper levels are maintained at a suitable level. The doctor may need to increase or decrease your dose of Cufence.
Nervous system problems can occur (for example, shaking, lack of coordination, slurred speech, muscle stiffness and worsening of muscle spasms), especially in patients just starting treatment with Cufence. If you notice these whilst taking Cufence, you must tell your doctor immediately.
Lupus-like reactions (symptoms may include persistent rash, fever, joint pain, and tiredness) have been reported in some patients switched to trientine medicine after penicillamine medicine. However, it was not possible to determine if the reaction was due to trientine or to previous penicillamine treatment.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
If you are taking iron tablets or medicines that neutralise the acid in your stomach, leave at least 2 hours before or after you have taken Cufence because they may reduce Cufence’s effect. It is recommended that trientine is taken at least one hour apart from any other medicinal product.
Take this medicine with water only. Do not take it with other drinks, milk or food because they may reduce the medicine’s effect. Avoid eating or drinking (except water) for 2 hours before and 1 hour after taking Cufence.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. It is very important to continue treatment to maintain normal copper levels during pregnancy. You and your doctor should fully discuss the potential benefits of treatment whilst considering any possible risks that there may be. Your doctor will advise you which treatment and which dose is best in your situation. If you become pregnant whilst taking Cufence, talk to your doctor.
If you are pregnant and taking Cufence, you will be monitored throughout your pregnancy for any effects on the baby or changes in your copper levels.
The limited information available suggests that Cufence does not pass into breast milk, but it is not certain that there is no risk to the baby. It is important to tell your doctor if you are breast-feeding or plan to do so. Your doctor will then help you decide whether to stop breast-feeding or to stop taking Cufence, considering the benefit of breast-feeding to the baby and the benefit of Cufence to the mother. Your doctor will decide which treatment and which dose is best in your situation.
Trientine is not likely to have an effect on your ability to drive or use machines.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
