The following adverse experiences were reported during a multicenter clinical trial comparing NILANDRON (nilutamide) + leuprolide versus placebo + leuprolide. The most frequently reported (greater than 5%) adverse experiences during treatment with NILANDRON (nilutamide) tablets in combination with leuprolide are listed below. For comparison, adverse experiences seen with leuprolide and placebo are also listed.
|NILANDRON + leuprolide

Some frequently occurring adverse experiences, for example hot flushes, impotence, and decreased libido, are known to be associated with low serum androgen levels and known to occur with medical or surgical castration alone. Notable was the higher incidence of visual disturbances (variously described as impaired adaptation to darkness, abnormal vision, and colored vision), which led to treatment discontinuation in 1% to 2% of patients.
Interstitial pneumonitis occurred in one ( < 1%) patient receiving NILANDRON (nilutamide) in combination with surgical castration and in seven patients (3%) receiving NILANDRON (nilutamide) in combination with leuprolide and one patient receiving placebo in combination with leuprolide. Overall, it has been reported in 2% of patients receiving NILANDRON (nilutamide) . This included a report of interstitial pneumonitis in 8 of 47 patients (17%) in a small study performed in Japan.
