Antibiotics to treat ear infections are a sticky subject for me. I was a child prone to ear infections. I had 2 -3 a year from birth on. I had tubes three times with the last time being when I was 18 years old. I was CONSTANTLY on meds and as I took them more and more, I grew allergic to them. I take them 2 – 3 times and then the next time, I’d break out in horrible hives. Now I’m allergic to penicillin, sulfa, etc. Pretty much the only thing I can take is Zithromax. I can’t say for certain that the many medicines in my childhood contributed to the allergies, but I definitely wouldn’t rule it out. My pediatrician agreed that’d we’d hold off on meds if Gabby ever had an infection, but so far we’ve been fine.
