I was wondering if anyone else has experienced a change in your hair, skin, or nails while on antibiotic treatment. I've been on azithromycin since August, and more recently started Bactrim. (And will be adding Ceftin in a week or so.) Since getting sick, my appearance has suffered, but everything is much worse on the abx. My hair is getting dry and brittle, my skin is breaking out, and my fingernails are really weak--to the point of tearing quite painfully. I've been trying to eat well, take my nutrition supplements, etc. Has this happened to anyone else, and does anyone have tips on how to improve the problem?
