THIS COMPLICATION OF SYPHILIS TREATMENT

Jarish-Herxheimer reaction: start general during 24 hrs of antibiotics therapy ,increase T,decrease BP,rigors,leukopenia
this occuring during treatment any of the spirochete disease

i think if there is any allergy for pencillin ,it is started with macularpapular RASH(the most comon rash seen in pencillin allergy),ANGIOEDEMA(marked swelling of the lips,tongue,periorbital area),and anaphylaxis may be BRONCHSPASM.....so there is just fever ,decrease BP,headache which happen from the KILLED organism that realse pyrogen(fever producing enzyme)......JARISCH HERXHEIMER PHENOMEN

I WISH I AM RIGHT

SO I AM STILL WITH ..D

D.Does not describe any features of allergy/anaphylaxis

  #9

Also penicillin allergy will manifest immediately after administration of the drug & not late in the evening. This is Jarish hex reflex no doubt, but do we have to continiue penicillin in same dosage or decrease it till patient stabilises....this Im not really sure.
