Gemtesa (vibegron) is used to treat overactive bladder (OAB) symptoms such as urinary urgency, frequency, and urge incontinence. It is used in adults with OAB or men with benign prostatic hyperplasia (BPH) who experience these symptoms. Gemtesa works by relaxing the bladder muscle, allowing the bladder to hold more urine, which helps reduce the urgency to urinate and decreases the frequency of urinary leaks.
