Dr. at nursing home gave my husband an antibiotic for a urinary tract infection that caused his leg to get beet red and ooze blood in an area about 4 inches square where his pants leg was burned to his leg. It took a year in the plastic surgery dept. to grow skin from the edges until the area was covered, but the skin is very vulnerable. When the antibiotic dose finished the leg returned to normal. Now it s doing it again and the Dr. says it s not the antibiotic. The antibiotic starts with a c and seems familiar to people at dialysis. Have you ever seen such an allergy for an antibiotic?
Hi & Welcome. I appreciate your concern for your beloved husband and sorry to know his skin problem which seems to be Chat Doctor. Based on the history given he seems to have developed a harmful skin condition called toxic epidermal necrosis. It is a potentially life-threatening skin disorder characterized by widespread redness of the skin, necrosis, and bulbous detachment of the epidermis and mucous membranes, resulting in exfoliation and possible sepsis and/or death (see the image below). Sulfonamides containing antibiotic Cotrimoxizole which is commonly prescribed to treat urinary tract infection appears to be the cause for his skin problem which occurs during the first 4 weeks of antibiotic therapy, usually between 1 and 3 weeks.  I have seen a few cases of antibiotic induced skin problems in my practice. Please see that he avoids taking Sulfonamides containing antibiotics in the future. Hope this answers your query.
