If you use a cream or suppository to treat the infection, don't depend on a condom or diaphragm for birth control. The oil in some medicines weakens latex, the material often used to make these devices.
Many women have infections that come back. If you have more than four yeast infections in a year, see your doctor. He or she may do some tests to see if your yeast infections are being caused by another health problem, such as diabetes.
If you practice good genital hygiene, you can help prevent infection.
Keep your vaginal area clean. Use mild, unscented soap and water. Rinse well.
After using the toilet, wipe from front to back to avoid spreading yeast or bacteria from your anus to the vagina or urinary tract.
Wear underwear that helps keep your genital area dry and doesn't hold in warmth and moisture. One good choice is cotton underwear.
Avoid tight-fitting clothing, such as panty hose, and tight-fitting jeans. These may increase body heat and moisture in your genital area.
Change out of a wet swimsuit right away. Wearing a wet swimsuit for many hours may keep your genital area warm and moist.
Change pads or tampons often.
Don't douche or use deodorant tampons or feminine sprays, powders, or perfumes. These items can change the normal balance of organisms in your vagina.
