Most cases were reversible with discontinuation and occurred within the first 3 mo of therapy.


Assess serum transaminase levels prior to starting treatment and at regular intervals for the first 4 mo of treatment and periodically thereafter. Obtain LFTs at the first sign or symptoms suggestive of liver dysfunction.


Category C .


Safety and efficacy in children have not been established.

Delay in adaptation to the dark

When passing from a lighted area to a dark area.


Severe liver injury has been reported. Hepatotoxicity in these reports generally occurred within the first 3 to 4 mo of treatment.

Patient Information

  • Start nilutamide tablets on the day of, or the day after, surgical castration. Patients should not interrupt their dosing of nilutamide or stop taking the medication without consulting their health care provider.
  • Delays of visual adaptation from light to dark may occur. Advise patients to use caution when driving at night or through tunnels. Patients can use tinted glasses to help decrease the problem.
  • Nilutamide may cause alcohol-intolerance. Avoid alcohol if facial flushing, malaise, or hypotension occurs after consuming alcoholic beverages.
  • Notify your doctor at the first sign or symptoms suggestive of liver dysfunction (eg, nausea, vomiting, abdominal pain, fatigue, anorexia, flu-like symptoms, dark urine, jaundice, right upper quadrant tenderness).
  • Tell health care provider immediately of any dyspnea or aggravation of preexisting dyspnea.
  • Instruct patients to report any new or worsening shortness of breath that they experience while on nilutamide. If symptoms occur, discontinue nilutamide immediately until it can be determined if the symptoms are drug-related.
