Finast 5mg is formulated with finasteride at 5mg per oral tablet. Finasteride selectively inhibits 5-alpha-reductase, reducing the conversion of testosterone into dihydrotestosterone. At the 5mg strength, finasteride is commonly used in medical management of benign prostatic hyperplasia, where reducing DHT can help address hormonal influences on prostate tissue.

The tablet format makes the dose easy to identify as part of a prescribed regimen. Because finasteride influences androgen metabolism, treatment should be taken according to professional instructions and continued consistently unless a clinician advises otherwise. The product is intended for appropriate medical use rather than casual or unsupervised dosing.
