Vaginal Itching: Causes and Relief

Vaginal itching causes compared

Common causes

Yeast infection

Vulvovaginal candidiasis affects most women at some point. Itching, burning and redness are the main symptoms, with thick white, cottage cheese-like or minimal discharge. Triggers include antibiotics, pregnancy, uncontrolled diabetes and a weakened immune system.

Irritants and allergies

Contact dermatitis of the vulva is very common and often overlooked. Triggers include scented soaps and bubble baths, wet wipes, douches, panty liners and pads, spermicides, latex condoms, laundry products, and over-the-counter creams, including some anti-itch creams. Shaving and waxing cause razor irritation and ingrown hairs.

Bacterial vaginosis

An imbalance of vaginal bacteria. Odor and discharge are more prominent than itching.

Low estrogen

After menopause, while breastfeeding, and with some medicines, the vulvar and vaginal skin becomes thinner and drier, causing itching, burning and pain with sex.

Vaginal itching without discharge

Itching with no discharge points away from infections and toward skin conditions: contact dermatitis, eczema, psoriasis, lichen sclerosus, lichen simplex chronicus (thickened skin from repeated scratching) or pubic lice and scabies.

Less common but important causes

• Lichen sclerosus: a chronic inflammatory skin condition causing intense itch and white, fragile skin. Without treatment it can scar and narrow the vaginal opening, and it slightly raises the risk of vulvar cancer.
• Sexually transmitted infections: trichomoniasis, herpes and pubic lice.
• Pinworms, especially in girls, with itching around the anus and vulva at night.
• Vulvar intraepithelial neoplasia and vulvar cancer: rare, but persistent itch with a lump, ulcer, thickened or discolored patch, particularly over 50, needs a biopsy.

Itching in girls before puberty

In children, vulvar itching is usually caused by irritation from soap or bubble baths, poor wiping, tight clothing or pinworms. Lichen sclerosus also occurs in girls. Any discharge, bleeding or concern about abuse should be assessed by a doctor.

How doctors find the cause

A doctor or nurse asks about discharge, odor, products used, sexual history, menopause and previous episodes, then examines the vulva and vagina. A swab is tested for pH, yeast, bacterial vaginosis and STIs. A small skin biopsy is taken for persistent itch, white patches, or any lump or ulcer.

Self-diagnosis is often wrong. Studies show many women who treat themselves for yeast actually have bacterial vaginosis, dermatitis or no infection.

Relief and treatment

Gentle care for any vulvar itch

• Wash the vulva once a day with plain water or a mild, unscented emollient. Avoid soap, bubble bath and douching.
• Pat dry, and wear loose cotton underwear. Sleep without underwear if possible.
• Use unscented, dye-free laundry detergent and avoid fabric softener on underwear.
• Avoid scented pads, liners and wipes.
• A cool compress or a plain emollient such as petroleum jelly can soothe.
• Try not to scratch. Keep nails short.

Cause-specific treatment

• Yeast: antifungal vaginal creams or suppositories (over the counter) or a prescription oral tablet. Avoid oral antifungals in pregnancy unless advised.
• Bacterial vaginosis and trichomoniasis: prescription antibiotics. Partners need treatment for trichomoniasis.
• Dermatitis: stop the trigger. A short course of mild steroid ointment can be prescribed.
• Lichen sclerosus: a strong steroid ointment, used as directed, controls it well. Long-term follow-up is advised.
• Low estrogen: vaginal moisturizers, lubricants, and low-dose vaginal estrogen.

Frequently asked questions

What causes vaginal itching without discharge?

Itching without discharge is usually a skin problem rather than an infection: irritation from soaps, wipes or pads, eczema, psoriasis, lichen sclerosus, or dryness from low estrogen. Pubic lice and pinworms can also cause it. A doctor can examine the skin and take a biopsy if needed.

How can I stop vaginal itching at home?

Stop using scented products, wash with water only, wear loose cotton underwear, use a cool compress and a plain emollient, and avoid scratching. If you have had a confirmed yeast infection before and the symptoms match, an over-the-counter antifungal may help. See a doctor if itch persists.

Is vaginal itching always a yeast infection?

No. Yeast is common, but irritation, bacterial vaginosis, low estrogen, STIs and skin conditions also cause itching. Using yeast treatment for the wrong cause can delay relief and even worsen irritation, so testing helps when symptoms are unusual or recur.

Why does vaginal itching get worse at night?

Itch often feels worse at night because there are fewer distractions, the skin is warm, and you may scratch in your sleep. Night-time itch is typical of lichen sclerosus, eczema and pinworms. Cool, breathable bedding and treating the cause help.

Can menopause cause vaginal itching?

Yes. Falling estrogen thins and dries the vulvar and vaginal tissues, causing itching, burning and pain during sex. Vaginal moisturizers and low-dose vaginal estrogen are effective. New itching after menopause with white patches or a lump should be checked.
