What medication is most effective for vaginitis?

Patient's question:

Patient Gender: Female
Patient Age: 22
Recently, I have had vaginal itching and an increase in vaginal discharge. I suspect it might be vaginitis. What should I do?

Doctor's answer:

Vaginitis is clinically characterized by changes in the nature of vaginal discharge and the main clinical features of vulvar itching, burning, and pain. Dyspareunia is also common. When the urethra is affected, symptoms such as dysuria and urinary urgency may occur. Common types of vaginitis include bacterial vaginosis, trichomoniasis, candidiasis, and atrophic vaginitis. Different diseases require different treatments, so it is important to first diagnose which type of vaginitis is present.
