Scabies: Why Is My Itching Getting Worse? - Dermatology

More Info

---

Scabies, caused by the Sarcoptes scabiei mite, is a highly contagious skin condition characterized by intense itching, especially at night. The itching is primarily due to an allergic reaction to the mites, their eggs, and their waste products. When you apply a scabicide, such as permethrin or benzyl benzoate, it is designed to kill the mites and their eggs. However, it is not uncommon for the itching to persist or even worsen after treatment, especially within the first few days.
There are several reasons why you might be experiencing increased itching despite following the treatment regimen:
1. Delayed Response: After applying the treatment, it can take time for the inflammation and allergic reaction to subside. The mites may be dead, but your skin may still be reacting to the remnants of the infestation. This can lead to continued itching for several days or even weeks after treatment.

2. Reinfestation: If your boyfriend had scabies and you were in close contact, it is possible that you were reinfested after treatment. Scabies is highly contagious, and if he did not complete his treatment or if he was in contact with infested bedding or clothing, he could have reinfested you.

3. Inadequate Treatment: Sometimes, the prescribed treatment may not be effective for everyone. Factors such as the severity of the infestation, the specific product used, or improper application can affect the outcome. It’s essential to follow the instructions carefully, ensuring that the medication is applied to all affected areas and left on for the recommended duration.

4. Secondary Infection: Scratching the itchy areas can lead to skin breaks, which may become infected. If you notice increased redness, swelling, or pus, it could indicate a secondary bacterial infection, which would require additional treatment.

5. Individual Variation: Each person's immune response can differ. Your boyfriend may have a different sensitivity to the mites or a more robust immune response, leading to a quicker resolution of symptoms.
Given your situation, here are some recommendations:
- Follow Up with Your Doctor: If the itching persists or worsens, it’s crucial to consult your healthcare provider. They may recommend additional treatments or investigate other potential causes for your symptoms.

- Avoid Scratching: Although it’s challenging, try to avoid scratching the affected areas to prevent further irritation or infection. Keeping your nails short and wearing gloves at night can help.

- Wash Bedding and Clothing: To prevent reinfestation, wash all bedding, clothing, and towels in hot water and dry them on high heat. Items that cannot be washed can be sealed in a plastic bag for at least 72 hours to kill any remaining mites.

- Use Anti-itch Treatments: Over-the-counter antihistamines or topical corticosteroids may help alleviate itching. However, consult your doctor before using any additional medications.

- Monitor Symptoms: Keep track of your symptoms and any changes. If you notice signs of infection or if the itching does not improve, seek medical attention promptly.

In summary, while it is not uncommon for itching to persist after scabies treatment, it is essential to monitor your symptoms and consult your healthcare provider for further evaluation and management. Scabies can be effectively treated, but it may take time for your skin to heal completely.
