If you are pregnant, talk with your doctor if you have any symptoms. Some problems can affect your pregnancy, so it is important to talk with your doctor and get the right treatment.
Yeast infection: If you have had a yeast infection before and can recognize the symptoms, and you aren't pregnant, you can treat yourself at home with medicines you can buy without a prescription. You can use an antifungal cream or suppository that you put into your vagina. Or your doctor may prescribe antifungal tablets that you swallow.
Bacterial vaginosis: Doctors usually use antibiotics to treat this problem. It is usually a mild problem. But it can lead to more serious problems, so it's a good idea to see your doctor and get treatment.
Trichomoniasis: This infection is also treated with antibiotics. Both you and your sex partner need treatment.
Atrophic vaginitis: This usually is treated with estrogen creams or tablets.
How can you prevent vaginitis?
Do not take antibiotics unless you really need to.
Do not douche.
Do not use feminine deodorant sprays or other perfumed products in or around your vagina.
During your period, change tampons at least 3 times a day, or switch between tampons and pads. Don't leave tampons in for more than 8 hours. And be sure to remove the last tampon you use.
Use a condom during sex. Limit your number of sex partners.
