I do not have hives, but I do get really bad itchy skin. Its all over. Not every day but the other night it kept me up for hours. I was on 8 months of tetracyclin and just switched a month ago to Keflex. Iam not sure if it is the meds or what it is from.
Itchy skin can be a symptom of liver problems, which can occur with antibiotic use. Do you get your liver function tested with blood tests on a regular basis? If not, I would suggest that you contact your doctor as soon as possible.
On the original topic, I don't believe that hives occur with liver problems. Otherwise, I'd be suggesting the same thing.
