Hi Lilith, I would call the doc to make sure before your next infusion. With all of those antibiotics that we often take together, it doesn't surprise me that we have reactions. I have heard that about Tobra, I get a little tingling sensation when I infuse the Tobra, it's not painful but, but my doc said that was okay as long as I had.no breathing problems or giant hives. She said just to watch it, but always better to be safe. I will keep you in my thoughts. Hugs, Jenn <img src="i/expressions/face-icon-small-smile.gif" border="0">
