Interstitial pneumonitis, including pulmonary fibrosis has been reported rarely post-marketing. Symptoms included exertional dyspnea, cough, chest pain, and fever.

Most cases occurred within the first 3 months of treatment with nilutamide, and most reversed with discontinuation of therapy.”

What should I watch for while using this medication?
Before using Nilutamide, Nilandron/Anandron make sure your physician is aware of any allergies or medications you currently take, pre-existing medical conditions and activities you perform. Patients receiving nilutamide may experience aplastic anemia because of a suppression in their testosterone levels; should monitor CBC periodically. Interstitial pneumonitis has been reported in patients receiving nilutamide. Discontinue Nilutamide, Nilandron/Anandron immediately if signs and/or symptoms of interstitial pneumonitis are observed until a causal effect can be ruled out. There has been a delay in adapting to dark conditions ranging from a few seconds to a few minutes after passing from a light to a dark area. This may not abate with continued treatment although may be alleviated by wearing tinted sunglasses. Caution patients who experience adaptation delay about driving at night or through tunnels. Prolonged use of antiandrogen therapy is associated with decreased bone mineral density and an increased risk of osteoporosis and fracture. Evaluate risk carefully before initiating therapy. Hyperglycemia has been observed; use with caution in diabetic patients and monitor for loss of glucose control.
