Sanjin tablets are used for inflammation of the urinary system, and the course of treatment for Sanjin tablets is about one week. Urological inflammation, also known as urinary tract infection, is an inflammatory response of the urinary epithelium to bacterial invasion. The main manifestation is bladder irritation signs, namely frequent, urgent and painful urination, discomfort in the bladder area and perineum, burning sensation during urination, and varying degrees of frequency. It is most common in female patients because their urethra is shorter and very close to the anus and vagina, which can easily contaminate the urethra and cause acute cystitis. In addition to using three gold tablets, it is recommended to take oral cephalosporins or levofloxacin for three days. Usually drink more water, urinate more often, eat less spicy and stimulating food, and keep the daily water intake above 2000 ml.
