Patient Medication Information: uses, side effects, how to take - Riva-Finasteride (Laboratoire Riva, 5 mg)
ABOUT THIS MEDICATION
RIVA-FINASTERIDE IS FOR USE BY MEN ONLY.
What the medication is used for
RIVA-FINASTERIDE is used to treat symptoms of benign prostatic hyperplasia (BPH) in men with an enlarged prostate. RIVA-FINASTERIDE may also be used to reduce the risk of developing a sudden inability to pass urine and the need for surgery. Your physician may prescribe RIVA-FINASTERIDE along with another medicine, called doxazosin (an alpha-blocker), to help you better control your BPH symptoms.
If your physician has prescribed doxazosin as well, please read the patient information provided for this product too.
RIVA-FINASTERIDE is not approved for the prevention of prostate cancer.
What it does
RIVA-FINASTERIDE lowers levels of a key hormone called DHT (dihydrotestosterone), which is a major cause of prostate growth. Lowering DHT leads to shrinkage of the enlarged prostate gland in most men. This can lead to gradual improvement in urine flow and symptoms over the next several months. RIVA-FINASTERIDE will help reduce the risk of developing a sudden inability to pass urine (acute urinary retention) and the need for surgery.
