My husband is on cipro for a urinary tract infection. He has been taking it since Thursday, 12/22. Has had 3 complete doses (6 pills). He has developed a dark skin rash on both legs and back of his upper thighs. His allergic hx is only to seafood/iodine. Has no other symptoms like itching, blistering, shortness of breath, etc. Should we be concerned about this? He was febrile, but after 48 hours on cipro, his fever has subsided. His is feeling much better, since starting the cipro. Thank you.
