My daughter was just diagnosed with CA-MRSA and is 33 weeks pregnant. She is also allergic to Duricef, Septra and Ceclor. Are there any antibiotics that she will be able to take safely? The site of the infection has been lanced,drained and packed and then the packing was removed the next day. This is on the back of her leg just below her buttocks. The area of redness and swelling is now approximately the size of a softball. The ER told her there is nothing that can be done for her due to her allergies and pregnancy.
