Introduction
Itchy skin, medically known as pruritus, is a common symptom caused by allergic reactions, dry skin, insect bites, rashes, or underlying medical conditions. Persistent itching can lead to scratching, skin damage, infection, and discomfort.
Effective relief often combines home remedies and topical treatments, including:
- Oatmeal baths
- Calamine lotion
- Topical corticosteroids (Hydrocortisone)
Understanding when and how to use these therapies can ease symptoms and promote skin healing.
Causes of Itchy Skin

- Allergic reactions: Hives, contact dermatitis (nickel, fragrances, poison ivy)
- Insect bites: Mosquitoes, fleas, bedbugs
- Skin conditions: Eczema, psoriasis, fungal infections
- Medications or systemic conditions: Liver or kidney disorders, thyroid issues
1. Oatmeal Baths
How They Work

2. Calamine Lotion
How It Works

3. Topical Hydrocortisone
How It Works
- A mild corticosteroid that reduces inflammation, redness, and immune response

When to See a Doctor
Seek medical attention if:

Conclusion
Itchy skin can be uncomfortable and disruptive, but relief is possible using safe home remedies like oatmeal baths and calamine lotion, along with topical hydrocortisone for moderate inflammation.
