Finasteride tablets, are a 5α-reductase inhibitor, indicated for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate to (1.1): • Improve symptoms • Reduce the risk of acute urinary retention • Reduce the risk of the need for surgery including transurethral resection of the prostate (TURP) and prostatectomy. Finasteride tablets administered in combination with the alpha-blocker doxazosin is indicated to reduce the risk of symptomatic progression of BPH (a confirmed ≥4 point increase in American Urological Association (AUA) symptom score) (1.2). Limitations of Use: Finasteride tablets are not approved for the prevention of prostate cancer (1.3). 1.1 Monotherapy Finasteride tablets are indicated for the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with an enlarged prostate to: -Improve symptoms -Reduce the risk of acute urinary retention -Reduce the risk of the need for surgery including transurethral resection of the prostate (TURP) and prostatectomy. 1.2 Combination with Alpha-Blocker Finasteride tablets administered in combination with the alpha-blocker doxazosin is indicated to reduce the risk of symptomatic progression of BPH (a confirmed ≥4 point increase in American Urological Association (AUA) symptom score). 1.3 Limitations of Use Finasteride tablets are not approved for the prevention of prostate cancer.

Finasteride tablets are contraindicated in the following: • Hypersensitivity to any component of this medication. • Pregnancy. Finasteride use is contraindicated in females when they are or may potentially be pregnant. Because of the ability of Type II 5α-reductase inhibitors to inhibit the conversion of testosterone to 5α-dihydrotestosterone (DHT), finasteride may cause abnormalities of the external genitalia of a male fetus of a pregnant female who receives finasteride. If this drug is used during pregnancy, or if pregnancy occurs while taking this drug, the pregnant female should be apprised of the potential hazard to the male fetus. [See also Warnings and Precautions (5.3), Use in Specific Populations (8.1), and How Supplied/Storage and Handling (16).] In female rats, low doses of finasteride administered during pregnancy have produced abnormalities of the external genitalia in male offspring. Hypersensitivity to any components of this product (4). Females who are or may …

• Finasteride reduces serum prostate specific antigen (PSA) levels by approximately 50%. However, any confirmed increase in PSA while on finasteride may signal the presence of prostate cancer and should be evaluated, even if those values are still within the normal range for men not taking a 5α-reductase inhibitor (5.1). • Finasteride may increase the risk of high-grade prostate cancer (5.2, 6.1). • Females should not handle crushed or broken finasteride tablets when they are pregnant or may potentially be pregnant due to potential risk to a male fetus (5.3, 8.1, 16). • Finasteride is not indicated for use in pediatric patients or females (5.4, 8.1, 8.2, 8.4, 12.3). • Prior to initiating treatment with finasteride for BPH, consideration should be given to other urological conditions that may cause similar symptoms (5.6). 5.1 Effects on Prostate Specific Antigen (PSA) and the Use of PSA in Prostate Cancer Detection In clinical studies, finasteride reduced serum PSA concentration by approximately 50% within six months of treatment. This decrease is predictable over the entire range of PSA values in patients with symptomatic BPH, although it may vary in individuals. For interpretation of serial PSAs in men taking finasteride, a new PSA baseline should be established at least six months after starting treatment and PSA monitored periodically thereafter. Any confirmed increase from the lowest PSA value while on finasteride may signal the presence of prostate cancer and should be …

8.1 Pregnancy Risk Summary Finasteride is contraindicated in pregnant females and not indicated for use in females. Based on animal studies and the mechanism of action, finasteride may cause abnormal development of external genitalia in a male fetus if administered to a pregnant female [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.1)]. In an embryo-fetal development study in rats, there was a dose-dependent increase in hypospadias that occurred in 3.6 to 100% of male offspring of pregnant rats administered oral finasteride during the period of major organogenesis at doses approximately 0.1 to 86 times the maximum recommended human dose (MRHD) of 5 mg/day (based on AUC at …
