L-Thyroxine induced maculopapular rash: A case report

Levothyroxine sodium (LT4) is a thyroid hormone prescribed as supplemental therapy in congenital and acquired hypothyroidism. This pathology is common in general population with an incidence of 4.1/1000 per year in women and 0.6/1000 per year in men. Though widely used, few cases of levothyroxine allergy are reported. Here we report a case of 44 year old male, who following two months of treatment initiation with L thyroxine 75 mcg, he manifested with hypersensitivity reactions progressing in form of maculopapular rash.
