When mycoplasma and chlamydia infections occur, they need to be treated with macrolide antibiotics, which include erythromycin capsules, dirithromycin capsules, azithromycin injection or minocycline. As a proprietary Chinese medicine preparation, Sanjin Tablet is only suitable for urinary tract irritation symptoms after mycoplasma and chlamydia infections, and plays an auxiliary treatment role in relieving symptoms such as urinary urgency, urinary frequency or painful urination, and is not a method of etiological treatment. Therefore, Sanjin tablets can be used in various pathogenic infections of the urethra, such as gonococcal urethritis, non-specific urethritis or other parts of the urinary tract, such as cystitis or pyelonephritis, etc. can be used to supplement the treatment. However, the main therapeutic effect also needs to be based on the results of urine culture and drug sensitivity test to select the targeted antimicrobial agents in order to achieve a complete cure.
