A yeast infection is a type of fungal infection. The main cause of vaginal yeast infections is a common yeast called Candida albicans.
There are both over-the-counter (OTC) and prescription treatments for yeast infection. It is important to have a doctor confirm a diagnosis of yeast infection before using over-the-counter treatments because symptoms of vaginal yeast infections can be similar to many other types of vaginal infections, and symptoms of yeast infection skin rashes can resemble other skin conditions.
The fastest way to get rid of a yeast infection is an antifungal medication called fluconazole (Diflucan) that requires a prescription from a doctor. It is an oral medicine that typically only requires one dose. If symptoms do not go away or recur, additional doses may be needed.
A steroid cream such as hydrocortisone may be prescribed to help relieve itching and inflammation.
OTC Yeast Infection Treatments
Topical antifungal ointments and creams are available over-the-counter to treat a yeast infection. For vaginal yeast infections, they are usually available in 1-day, 3-day, or 7-day formulations.

What Causes a Yeast Infection?
Candida albicans lives on the skin and inside the body, such as in the mouth, throat, gut, and vagina, and it usually does not present any problems in most people, but when it grows out of control it can cause infections.
Yeast infections commonly refer to candidiasis in the vagina in women, but yeast infections can also occur in men on the penis, and on the skin causing rashes such as intertrigo (a rash and irritation of the folds of the skin) and diaper rash in infants.
Risk factors for developing a yeast infection include:
- Prolonged use of antibiotics
- Excessive sweating
- Increased age
- A weakened immune system, such as from HIV, cancer treatments, and other causes
- Obesity, especially in people who have large skin rolls where fungi can thrive
- Genetic predisposition to skin disease
- Exposure to sweat, urine, and feces in the diaper area in infants
