Finasteride Tablet
Finasteride is a 5-alpha-reductase inhibitor used in male dogs to manage benign prostatic hyperplasia (BPH). By blocking the conversion of testosterone to dihydrotestosterone (DHT), it causes the enlarged prostate to shrink, relieving urinary straining in intact male dogs. Finasteride (off-label in veterinary use) can significantly reduce prostate size in dogs without adversely affecting fertility or testosterone levels, making it a valuable therapy for non-surgical BPH management.
The uses and pharmacology described below reflect the FDA-approved labeling for this active ingredient; your veterinarian determines whether and how they apply to your animal's treatment plan.
