“…A chance observation of improvement of skin lesions of pityriasis rosea in two patients who were given erythromycin for upper respiratory tract infections, also confirms this hypothesis [9]. It has already been established that drugs like allopurinol, arsenic, bismuth, barbiturate, gold, hydrochlorothiazide, organic mercurials, nimesulide, d-penicillamine, clonidine, isotretinoin and ketotifen can cause eruptions resembling pityriasis rosea [10][11][12].

“…It is usually self-limiting and disappears after 4 weeks. Pharmacological treatment includes topical as well as oral steroids, antibiotics such as macrolides and antihistamines to control itching [1,2].
