How to treat scabies in my 4-month-old daughter?

Question

Hello doctor,

My four-month-old daughter was diagnosed with scabies and was prescribed Permethrin. We applied the first dose and washed it off after eight hours. After that, I applied aloe vera gel to her body and tea tree oil to her scalp to help with the itching.

A few days later, I noticed tiny rashes, and by the next day, the rash had spread all over her face, with no clear areas. It is also present on her arms, and small spots can be seen on her body. She has not been sleeping well and becomes restless both while awake and asleep, as if her body is bothering her.

As of three weeks ago, her weight was 14 pounds.

Please advise.

Thank you.

Hello,

Welcome to icliniq.com.

I understand how upsetting this must be for you, especially seeing such discomfort in a four-month-old baby. In infants, scabies often behaves differently than in older children and adults, and it commonly affects the face, scalp, neck, and trunk, even after the first correct application of Permethrin. New rashes and worsening itching can appear for one to two weeks due to the body’s inflammatory reaction to dead mites, a condition known as post-scabies dermatitis.

Permethrin itself can also cause skin irritation in babies, particularly on delicate facial skin, which may explain the sudden spread of tiny rashes and increased restlessness. Based on history and the attached picture (attachments removed to protect the patient’s identity), she has probably developed contact dermatitis, which is very clear on her eyes in the photo. The cause could be tea tree oil or Permethrin itself.

In infants, the skin barrier is very delicate, and substances such as Permethrin, essential oils like tea tree oil, and even aloe vera can easily cause contact dermatitis. Tea tree oil in particular is not safe for babies and can lead to significant skin inflammation and increased irritability.

In contact dermatitis, the skin becomes inflamed, red, and covered with tiny bumps, and the itching can be intense, which explains why she has been uncomfortable both while awake and asleep. This reaction does not mean that something dangerous has happened, but it does mean that her skin needs time to recover and should be protected from further irritation.

For treatment, apply Fluocinolone acetonide (0.01%) cream or lotion on the affected area once daily for five to six days (being careful not to go inside the eyes), apply gently around the eyes only, along with a bland moisturizer like petroleum jelly after shower, and switch to non-bacterial soap. Avoid tea tree and aloe vera gel for some days. In case of itching ,give her syrup Cetirizine at bedtime. Consult your specialist doctor, discuss with them, and take the medicines with their consent.

Your baby’s weight is appropriate for her age, which is reassuring, and with gentle care and this treatment, her skin comfort and sleep will gradually return to normal.

I hope it helped with your query.

Thank you.
