Side Effects & Adverse Reactions

Interstitial Pneumonitis

Interstitial pneumonitis has been reported in 2% of patients in controlled clinical trials in patients exposed to nilutamide. A small study in Japanese subjects showed that 8 of 47 patients (17%) developed interstitial pneumonitis. Reports of interstitial changes including pulmonary fibrosis that led to hospitalization and death have been reported rarely post-marketing. Symptoms included exertional dyspnea, cough, chest pain, and fever. X-rays showed interstitial or alveolo-interstitial changes, and pulmonary function tests revealed a restrictive pattern with decreased DLco. Most cases occurred within the first 3 months of treatment with NILANDRON, and most reversed with discontinuation of therapy. A routine chest X-ray should be performed prior to initiating treatment with NILANDRON. Baseline pulmonary function tests may be considered. Patients should be instructed to report any new or worsening shortness of breath that they experience while on NILANDRON. If symptoms occur, NILANDRON should be immediately discontinued until it can be determined if the symptoms are drug related.

Hepatitis

Rare cases of death or hospitalization due to severe liver injury have been reported post-marketing in association with the use of NILANDRON. Hepatotoxicity in these reports generally occurred within the first 3 to 4 months of treatment. Hepatitis or marked increases in liver enzymes leading to drug discontinuation occurred in 1% of NILANDRON patients in controlled clinical trials.

Serum transaminase levels should be measured prior to starting treatment with NILANDRON, at regular intervals for the first 4 months of treatment, and periodically thereafter. Liver function tests should also be obtained at the first sign or symptom suggestive of liver dysfunction, e.g. nausea, vomiting, abdominal pain, fatigue, anorexia, "flu-like" symptoms, dark urine, jaundice, or right upper quadrant tenderness. If at any time, a patient has jaundice, or their ALT rises above 2 times the upper limit of normal, NILANDRON should be immediately discontinued with close followup of liver function tests until resolution.

Use in Women

NILANDRON has no indication for women, and should not be used in this population, particularly for non-serious or non-life threatening conditions.

Other

Foreign postmarketing surveillance has revealed isolated cases of aplastic anemia in which a causal relationship with NILANDRON could not be ascertained.
