If a person has pneumococcal pneumonia and a Penicillin allergy, what other antibiotics can be used to treat them?

cephalosporines(10-15% cross sensitivity with penicillin) or better erytromicin or some of quinolones(like ciprofloxacin)

  #3

What about Vancomycin?

Vancomycin is often termed"antibiotic of last resort",used mainly to kill MRSA(Methicillin resistant Staph.aureus and Clostridium difficile,as it is extremely efficient in killing Gram positives-BUT there is an emergence of Vancomycin abuse in the hospitals-therefore,now you have emerging resistance of bugs to Vancomycin(Enterococcus for exmpl.) and there is a trend to leave this drug ALONE,unless really nothing else works!

Therefore,as Pneumococcus is thought NOT to be resistant to penicillins and penicilin related compounds-NO VANCOMYCIN!

Right. Thank you.
