One capsule inserted into the vagina can be effective for 4 days, so you should not have intercourse until 1 week after you stop using Kenetin. Kenitin is mainly used to treat Candida vaginitis, so it is best to go to the hospital after stopping the drug to review the routine examination of the leukorrhea, if Candida has turned negative, and three consecutive leukorrhea tests are negative, the clinic is considered to be cured, and only then you can have sex. Otherwise, even if the clinical symptoms have disappeared, Candida is still in the vagina, and once the resistance drops, it is likely to multiply again, causing the corresponding clinical symptoms. Through sexual contact will also be transmitted to the sexual partner, causing the partner to develop Candida circumcision or Candida glans.
