weakness, and anemia. However, most men have preserved sexual function with bicalutamide monotherapy. In females, due to the minimal biological importance of androgens in this sex, the side effects of pure antiandrogens or are few, and bicalutamide has been found to be very well tolerated. However, bicalutamide has been found to increase levels of total and LDL cholesterol in women. General side effects of bicalutamide that may occur in either sex include diarrhea, constipation, abdominal pain, nausea, dry skin, itching, and rash. The drug is well-tolerated at higher dosages than 50 mg/day, with rare additional side effects. Bicalutamide has been associated with abnormal liver function tests such as elevated liver enzymes. In the Early Prostate Cancer (EPC) clinical programme of bicalutamide for and , the rate of abnormal liver function tests with bicalutamide monotherapy was 3.4% relative to 1.9% for placebo. However, higher rates, up to 11%, have been seen in other studies. Hepatic changes that have necessitated discontinuation of bicalutamide, such as marked increases in liver enzymes or hepatitis, have occurred in 0.3 to 1.5% of men in clinical trials, or approximately 1% overall. Elevated liver enzymes with bicalutamide usually occur within the first 3 to 6 months of treatment. Monitoring of liver function during treatment is recommended, particularly in the first few months. In men with early prostate cancer, bicalutamide monotherapy has been found to increase non-prostate cancer mortality. The reasons for the increase in mortality with bicalutamide in these men are unknown, but possible factors could include androgen deprivation or drug-related toxicity of bicalutamide. There are 10 published case reports of liver toxicity associated with bicalutamide as of 2022. Death occurred in 2 of these cases. Hundreds of additional cases of liver complications in people taking bicalutamide exist in the FDA Adverse Event Reporting System (FAERS) database. In all of the published case reports of liver toxicity with bicalutamide, the onset of symptoms was within the first 6 months of treatment. Symptoms that may indicate liver dysfunction include nausea, vomiting, abdominal pain, fatigue, anorexia, "flu-like" symptoms, dark urine, and jaundice. There are also published case reports of interstitial pneumonitis and eosinophilic lung disease associated with bicalutamide. along with hundreds of additional instances in the FAERS database as well. Interstitial pneumonitis can potentially progress to pulmonary fibrosis and may be fatal. Symptoms that may indicate lung dysfunction include dyspnea (difficult breathing or shortness of breath), cough, and pharyngitis
