Feminine Anti-Itch Creams: When the Cream Becomes the Problem

Vulvar itching is common after menopause, and the drugstore offers plenty of “feminine anti-itch” creams. Many contain a numbing ingredient such as benzocaine or lidocaine, sometimes with fragrance or soothing botanicals. They can bring quick relief. But if the itch keeps returning, the cream itself may be part of the problem.

What patch-test studies found

Doctors use patch testing to find out whether someone is allergic to an ingredient touching their skin.

• Numbing agents stand out. In a North American study of patients referred for patch testing, allergies to benzocaine and dibucaine, both numbing ingredients, were significantly more common in people with genital and anal-area rashes. So were allergies to a fragrance ingredient and two corticosteroids.¹
• Medicine and fragrance allergies were usually relevant. In 282 women tested for vulvar symptoms, about half had an allergic contact rash. Itching was the most common complaint. Fragrances and topical antibiotics or numbing creams were found less often than some allergens, but when they were, they were almost always relevant to the woman’s symptoms.²
• Trying many products raises the odds. In a study of 43 women with vulvar itching, 44% had at least one allergy relevant to their symptoms. Using multiple topical treatments was one factor linked to a greater chance of allergy.³

Allergies can also be missed: many relevant allergens weren’t on the standard patch test series, so the testing had to include women’s own over-the-counter products.³

Signs the cream may be making things worse

• The itch improves for a few hours, then comes back stronger
• New redness, swelling, burning or rash where you apply it
• You’ve tried several products, and nothing helps for long

If that sounds familiar, stop using the products you’ve been applying and see a clinician. Bring them, or photos of the ingredient lists, to your visit.

Itching that needs a diagnosis

Long-lasting vulvar itch after 50 has many causes, including thinning tissue after menopause, yeast, skin conditions such as lichen sclerosus, and irritation from soaps or pads. Our guides to why the vulva itches and lichen sclerosus follow-up explain what to look for. A numbing cream can cover up symptoms that need treatment.

If you use an anti-itch cream

1. Use it short term and follow the label.
2. Choose fragrance-free products with short ingredient lists.
3. Use one product at a time, so you can tell what helps or irritates.
4. Skip scented washes and wipes. Our article on feminine washes and wipes covers what the vulva needs.

Try: “I’ve had vulvar itching for months and used several creams. Could I be allergic to one of them, and should I have patch testing or a closer exam?”
