Pityriasis rosea

Diagnosis

Healthcare providers often diagnose pityriasis rosea through visual examination of the rash alone. However, in some cases, a skin biopsy may be necessary. During a skin biopsy, a small sample of the rash is taken for examination under a microscope. This test aids in distinguishing pityriasis rosea from other similar rashes.

Treatment

Without treatment, pityriasis rosea typically resolves itself in four to ten weeks. The disease normally goes away without leaving any scars and doesn’t reappear. See your healthcare provider about treatments if the itching bothers you or if the rash doesn’t go away by then.

• Medications: If home remedies prove ineffective in alleviating symptoms or shortening the duration of pityriasis rosea, your healthcare provider may suggest medication. Corticosteroids and antihistamines are commonly prescribed for this condition. One example is prednisone, a corticosteroid administered orally with a glass of water. Prednisone works by reducing inflammation throughout the body, including the skin. Antiviral medications that aid your body in combatting harmful viruses.
• Light therapy/ phototherapy: Phototherapy employs UVB (ultraviolet B) light from specialized lamps for treatment. Sunlight’s UV light wave may also aid in treating skin conditions like pityriasis rosea. However, individuals with darker skin are advised to consult a healthcare provider before undergoing treatment. This precaution is necessary because UVB exposure can lead to hyperpigmentation, causing permanent dark spots in individuals with darker skin, even after the rash has healed.
