Syprine Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Syprine (trientine) is used to treat Wilson's disease in people who cannot take penicillamine (Cuprimine, Depen). It is a chelating agent that works by removing heavy metals from the blood. Common side effects include skin rash, muscle spasm or contractions, heartburn, stomach pain, loss of appetite, or skin flaking, cracking, or thickening.
The recommended initial dose of Syprine is 500-750 mg/day for pediatric patients and 750-1250 mg/day for adults given in divided doses two, three or four times daily. This may be increased to a maximum of 2000 mg/day for adults or 1500 mg/day for pediatric patients age 12 or under. Other drugs may interact with Syprine. Tell your doctor all medications and supplements you use. During pregnancy, Syprine should be taken only if prescribed. It may be harmful to a fetus. It is unknown if this drug passes into breast milk or if it could harm a nursing baby. Consult your doctor before breastfeeding.
