Vaginal candidiasis is usually treated with antifungal medicine. For most infections, the treatment is an antifungal medicine applied inside the vagina or a single dose of fluconazole taken by mouth. Other treatments may be needed for infections that are more severe, that don’t get better, or that keep coming back after getting better. These treatments include more doses of fluconazole taken by mouth or other medicines applied inside the vagina, such as boric acid, nystatin, or flucytosine.

Treatment for yeast infections depends on the severity and frequency of your infections, which doctor may recommend you below treatments

For Mild to Moderate Symptoms and Infrequent Episodes

• Short-course vaginal therapy. Taking an antifungal medication for three to seven days will usually clear a yeast infection. Antifungal medications — which are available as creams, ointments, tablets and suppositories — include miconazole (Monistat 3) and terconazole. Some of these medications are available over-the-counter and others by prescription only.
• Single-dose oral medication. Your doctor might prescribe a one-time, single oral dose of fluconazole (Diflucan). Oral medication isn’t recommended if you’re pregnant. To manage more-severe symptoms, you might take two single doses three days apart.

See your doctor again if treatment doesn’t resolve your symptoms or if your symptoms return within two months.

If Your Symptoms Are Severe

• Long-course vaginal therapy. Your doctor might prescribe an antifungal medication taken daily for up to two weeks, followed by once a week for six months.
• Multidose oral medication. Your doctor might prescribe two or three doses of an antifungal medication to be taken by mouth instead of vaginal therapy. However, this therapy isn’t recommended for pregnant women.
• Azole resistant therapy. Your doctor might recommend boric acid, a capsule inserted into your vagina. This medication may be fatal if taken orally and is used only to treat candida fungus that is resistant to the usual antifungal agents.
