What treatments are appropriate for tonsillitis when you have a penicillin allergy?

Zithromax. Azithromycin (zithromax) is a good option for streptococcal tonsillitis. There is some cross-reactivity between penicillins and cephalosporins (such as keflex), and these would not be my first choice. Many infections are caused by viruses, and in this situation antibiotics are not effective.

Yes. Despite increasing antibiotic resistance, there usually is another antibiotic that can be found. If this is not the case, and there is a serious need for penicillin, many penicillin allergies can be desensitized. This procedure takes place in the hospital and only lasts for the duration of time that you are taking penicillin, but is effective. So in emergencies, there are still options. Read more...
Yes. Almost all infections are treatable with non-penicillin antibiotics but if you develop an infection requiring penicillin, then you can be admitted to a hospital to undergo desensitization, a procedure which over a few hours "teaches" your body how to tolerate penicillin.
