Patient's question:
Here is the English translation of the provided text:"Regarding the treatment of trichomoniasis, since I didn’t have time to go to the hospital for medication, the doctor instructed me to buy metronidazole suppositories. After using them for seven days, I feel a little itchy. How long should I continue using them before stopping? Will prolonged use have side effects?"

Doctor's answer:
Metronidazole suppositories need to be used for 2-3 weeks. Trichomoniasis is prone to recurrence, so follow-up tests are necessary. It is recommended to pay attention to hygiene in the private area and change underwear frequently. After two weeks of medication, re-examine the discharge to see if it heals on its own. Subsequent follow-up tests after menstruation, with three negative results, indicate that the condition has healed. Vaginal infections are difficult to fully cure. Patients should maintain a positive attitude and face the condition with optimism, which can help increase their confidence in combating vaginal infections.
