I am very sensitive to antibiotics. I've only found one drug so far that's not an antibiotic that I am allergic to and that's Celebrex.. broke out in a rash 3 days after starting it. It's tough going to a doc when I really need antibiotics and having to go through what I am and am not allergic to. I'm also really sensitive to quinolone drugs.. it's technically not an allergy, but I had bad reactions which lead to tendonitis and months of physical therapy after taking Cipro one time and Levaquin the other. Try telling your doctor you can't take any drug in the quinolone class.. some don't even know what that mean! I refuse to take Levaquin, but one time I had to go to the ER for an infection in my foot and I told them I couldn't take quinolones, but yet she STILL gave me a prescription for Levaguin.. ARGH!!
