<s>[INST] Hello... My doctor said i have pityroasis rosea, due what she called a herald patch with little bumps which look like an insect bite... She said i need not worry, it will go away on its own after sometime. My doctor prescribed betamethasone lotion for rash and cetirizine hc for itchiness. My problem is the rash are on my neck and arms now.... How can i make it go away the soonest time possible... I think i have this for more or less 4 weeks and its all over my body... Hope you can help me... Thank you [/INST] Hi, Satyriasis rose will usually go away in 6 to 8 weeks without treatment. But as you have itching, you can continue using cetirizine and dexamethasone. You can continue following tips. Avoid taking hot showers or baths. Keep the water as cool as you can tolerate. Try an oatmeal bath, such as Aveiro Colloidal Oatmeal bath, to help relieve itching. Exposing the rash to sunlight may make it go away more quickly. Apply a moisturizer or calamine lotion to the skin while it is damp.[when you stop dexamethasone]. Wear cotton or silk clothing. Avoid wearing wool and acrylic fabrics next to your skin. Use as little soap as possible. Use gentle soaps, such as Basis, Detail, Dove, or Oil of Olay. Avoid deodorant soaps when you have a rash. Take care. Best regards, </s>
