Prevention - Vaginitis

Good hygiene may prevent some types of vaginitis from recurring and may relieve some symptoms:

Avoid baths, hot tubs and whirlpool spas. Rinse soap from your outer genital area after a shower, and dry the area well to prevent irritation. Don't use scented or harsh soaps, such as those with deodorant or antibacterial action.

Avoid irritants. These include scented tampons and pads.

Wipe from front to back after using the toilet. Doing so avoids spreading fecal bacteria to your vagina.

Other things that may help prevent vaginitis include:

Don't douche. Your vagina doesn't require cleansing other than normal bathing.
Repetitive douching disrupts the normal organisms that reside in the vagina and can actually increase your risk of vaginal infection. Douching won't clear up a vaginal infection.

Use a male latex condom. This helps avoid infections spread by sexual contact.
Wear cotton underwear and pantyhose with a cotton crotch. If you feel comfortable without it, skip wearing underwear to bed. Yeast thrives in moist environments
