Adverse reactions to medications are extremely common and display a characteristic clinical morphology including fixed drug eruption (FDE), urticaria, Stevens-Johnson syndrome, hypersensitivity syndrome, morbilliform exanthem, pigmentary changes and so on. Fixed drug eruption is commonly seen with antimicrobials and analgesics. Here we report a case of a 45 year-old male who presented to us with multiple bullous eruptions over the trunk, upper limbs and thighs after repeated doses of pseudoephedrine.
