**Question:** Drugs used in scabies are all except:

A. Antibiotics
B. Paracetamol
C. Anti-inflammatory drugs
D. Antidepressants

**Core Concept:**
Scabies is a skin infection caused by the mite Sarcoptes scabiei. The most commonly used treatment for scabies involves topical and systemic medications. Antibiotics, anti-inflammatory drugs, and antidepressants are not the primary drugs used for scabies treatment.

**Why the Correct Answer is Right:**
The correct answer, D (antidepressants), is right because antidepressants are not typically used in the treatment of scabies. The primary goals of scabies treatment are to kill the mites, alleviate symptoms, and prevent the infection from spreading. Topical and systemic medications targeting mites and their byproducts are more appropriate.

**Why Each Wrong Option is Incorrect:**
A) Antibiotics: Although antibiotics can sometimes be prescribed to treat bacterial infections that may coexist with scabies, they are not the primary drugs used for scabies itself.
B) Paracetamol: Paracetamol is a pain reliever and fever reducer, not specifically designed for scabies treatment. It may be used as an adjunct to scabies treatment, but it is not the primary drug.
C) Anti-inflammatory drugs: Anti-inflammatory drugs are not the primary drugs used for scabies treatment either. The primary focus is on mite elimination and symptom relief.

**Clinical Pearl:**
When treating scabies, it is essential to consider the specific mite-killing and symptom-relieving medications like lime sulfur yellow, permethrin, or benzyl benzoate. These drugs directly target the mites and their byproducts, while antibiotics, paracetamol, and anti-inflammatory drugs are adjunctive therapies with different pharmacological mechanisms.
