Hello,
The following are few probable causes of your sister's itchy rash:
1) Eczema
2) Allergic contact dermatitis
3) Urticaria
4) Psoriasis
5) Various infections like
fungal infection tenia corporis
6) Chicken pox, measles
7) Heat rash
8) Insect bites
Treatment depends upon the cause of your rash. The following are few treatment options:
1) Allergy medications: Oral antihistamines, a type of allergy medication, reduce itching
2) Anti-inflammatory creams:
Hydrocortisone creams like Cortisone soothe inflammation and itching.
3) Immunosuppressants: If the skin rash is from eczema or an immune system response, medicines can reduce the reaction. Calming it can minimize inflammation (irritation).
4) Oatmeal baths: Soaking in a warm bath with colloidal oatmeal can relieve dry, itchy skin rashes.
5)Steroids: If symptoms persist, your healthcare provider may prescribe a
topical steroid cream or an oral steroid like prednisone. Steroids ease inflammation and itchiness.
6) Topical immunomodulators: These medications change (modulate) your body’s immune system response to allergens.
Prescription medications include tacrolimus ointment (Protopicr) and
pimecrolimus skin cream (Elidelr). Please do consult your
dermatologist for prescription medications.
Take care. Hope I have answered your question. Let me know if I can assist you further.
