What To Take For Strep If Allergic To Penicillion
No cross reaction: Ampicillin and other penicillin-type antibiotics have a completely different chemical structure than erythromycin. Thus, the risk for allergic reaction to Ampicillin is no different than your average person. Your doctor can tell you which antibiotic (ampicillin, cipro, (ciprofloxacin) etc.) will be most effective for a given infection (sinus infection vs skin infection, etc.). See your doctor for more info. ...Read more
It depends: It depends on the type of penicillin allergy. If it's just a rash you can safely take cephalosporins like keflin.. If hives, throat swelling or anaphylaxis you cannot take cephalosporins. In this situation you usually need to take an antibiotic that is unrelated to penicillins (not a betalactam drug). ...Read more
What to do if I have strept throat, and im allergic to penicillin, can take amoxicillin or keflex instead?
No : Amoxicillin is within penicillin class and the risk of having a reaction is significant so it should be avoided. There is controversy about the risk of cross reaction between class of antibiotics penicillin and cephalosporin (keflex). It appears the risk is low (but not 0). If penicillin allergy was years ago, skin testing for penicillin can help know if it is still there. Allergist can help. ...Read more
Yes: As background, 90% of patients labelled as penicillin allergic are not. If one is labelled as pcn allergic then they should have pcn skin testing done to confirm or refute this diagnosis.

Yes: I have been using Ceftin (cefuroxime axetil) in penicillin allergic patients for years without any problem. You can safely take ceftin.

The latter is more expensive but has a very low rate of bacterial resistance. ...Read more

I'm allergic to penicillin and camping in remote area. Will 150 mg. Clindamycin. Treat my strep? Should I double it? How often do I take it?
Talk to doctor: I think catching a strep infection from camping is at the very low risk category. You should be more worried over GI or sinus issues. Discuss with your doctor re the best choice for your travel destination since clindamycin may lead to serious GI issue for some people and this is not something you would ever want to suffer in a remote area. ...Read more

Im allergic to everything but cipro (ciprofloxacin) and levaquin just got off 10 days of levaquin for strep didnt help sore throat time.have it back what can i take?
Virus, not strep?: The large majority of pharyngitis (sore throat) is viral, and no antibiotic works against viruses. Lack of improvement on levofloxacin (Levaquin®) is evidence it wasn't strep to begin with, or that it was strep plus a virus. This should continue to clear up on its own. Check with your doctor if it continues more than another few days. ...Read more

If allergic to it, other choices are the Erythromycin group, Cipro (ciprofloxacin) group, cephalosporin group. The last group should be taken with caution as there could be an associated cross-allergy in 10% of people. ...Read more
