Eulexin may also be used for purposes not listed in this medication guide.
Eulexin can cause serious liver problems. Call your doctor at once if you have upper stomach pain, itching, tired feeling, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).
You will need frequent blood tests to check your liver function while you are taking Eulexin.
