Hi Aunt Vadge,

My daughter is 10 and is on antibiotics for appendicitis. She told me her vagina is itchy. Is it safe for her to use a soothing cream?

Thank you,

Hi Sarah,

Poor love – appendicitis is more than enough without an itch on top. The good part is this is usually simple to sort, and the safest path with a child is clear.

The most likely cause is exactly what you’d suspect: antibiotics knock down the protective bacteria along with the bad, which can let a little yeast (thrush) flare up – common and harmless.

A couple of other things cause an itchy vulva in children too, including simple irritation and, very commonly, threadworms (especially if the itch is worse at night), and these need different treatments, which is why it’s worth getting checked rather than guessing.

On creams, please check first: I wouldn’t put an adult skincare product on a 10-year-old’s genital skin without an okay from her doctor, because a child’s skin there is delicate and the right treatment depends entirely on the cause.

The best move is a quick word with her GP, paediatrician or a pharmacist – if it’s thrush they can recommend a child-appropriate antifungal, and if it’s threadworms or something else they’ll treat that instead; it’s bread-and-butter for them.

For safe, gentle comfort meanwhile: loose, breathable cotton underwear so the area can air, gently discouraging scratching to avoid breaks in the skin, a cool damp cloth or wrapped ice pack against the area for the itch, a soothing oat bath (low-stakes and often very calming), and plain-water washing only (no soaps), wiping front to back.

A children’s gut probiotic – the kind made for restoring gut bacteria after antibiotics, not a vaginal one – can also be a gentle help, and your pharmacist can point you to a suitable one. You’re doing lovely mum work keeping her comfortable; if the itch doesn’t settle once she’s been seen, keep advocating until someone sorts it.

Here’s to her feeling better soon.

Lots of love,
Aunt Vadge
