Patient's question:
Medical Description: Hello, there were no trichomonas or Candida in the vaginal discharge. Cleanliness: 2.The doctor prescribed metronidazole pessary and Optiderm benzalkonium chloride solution.
History of Treatment and Effect: After using it for 3 days, I felt the vaginal itching had subsided, but I always thought I was using it incorrectly because I saw others say benzalkonium chloride needs to be diluted. Actually, I bought a spray of benzalkonium chloride 0.1%.
What Help I Need:
1. Is it indeed not necessary to dilute it? Can I directly spray it on the external genitalia?
2. My partner also has itching in the penis and scrotum. Can I also spray this benzalkonium chloride on him?
Doctor's answer:
Hello, benzalkonium chloride solution is what we commonly call "Sini'erjiermie," which is a solution used for disinfecting the skin and mucous membranes. The depth of disinfection for benzalkonium chloride solution on the skin and mucous membranes is 0.1%, which is the same as 0.1%, so no further dilution is needed. It can be used directly for disinfecting the skin and mucous membranes.This product is a clear liquid, colorless or light yellow; it has a fragrant odor and a very bitter taste. It is used for preoperative skin disinfection, mucous membrane and wound disinfection, and surgical instrument disinfection. When shaken, it produces a large amount of foam. It should not be used in combination with soaps or saline disinfectants. It is not suitable for disinfecting cystoscopes, ophthalmic instruments, or synthetic rubber products. It is a disinfectant and preservative.
