1. Why am I using TRIENTINE DR. REDDY’S?

TRIENTINE DR. REDDY’S contains the active ingredient trientine dihydrochloride.

Trientine is a chelating (KEE-late-ing) agent that works by removing copper from the blood.

Wilson’s disease is a genetic metabolic defect that causes excess copper to build up in the body.

Trientine dihydrochloride is used to treat this inherited condition in people who cannot take penicillamine.

2. What should I know before I use TRIENTINE DR. REDDY’S?


Do not use TRIENTINE DR. REDDY’S if:

  • you are allergic to trientine dihydrochloride, or any of the ingredients listed at the end of this leaflet.
    Always check the ingredients to make sure you can use this medicine.

Check with your doctor if you:

  • have any other medical conditions
  • take any medicines for any other condition
  • have anaemia (low red blood cells)

Your doctor will need to regularly check for symptoms of your disease and copper levels in your blood and urine. Regular monitoring is especially important at the start of your treatment and 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 TRIENTINE DR. REDDY’S.

Regular monitoring is also important if you have liver or kidney problems.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?
