MedicineNet.com confirms that pityriasis rosea usually disappears without treatment. Most cases clear within nine weeks without any medical intervention. Approximately 50 percent of cases experience some itching. When this happens, MedicineNet.com recommends using hydrocortisone lotions, oral antihistamines such as loratidine, and UVB rays or sunlight. Not getting too hot as a result of the weather, bathing or showering can reduce itching, according to MedicineNet.com. While these approaches won't make the rash clear faster, they do alleviate uncomfortable symptoms.
A rosea rash starts out as a circular red or pink spot on the back, chest or abdomen, according to Mayo Clinic. It may then grow and spread until the pattern looks like a pine tree, and it usually appears between the ages of 10 and 35. WebMD states that the rash can sometimes cause cold-like symptoms. This includes feeling tired, having a headache, and experiencing a sore throat, loss of apetite and nausea. WebMD also advises that doctors may prescribe an antifungal cream if they are uncertain that the rash is rosea, as it sometimes bears a resemblance to ringworm.Learn more about Skin Conditions
