Pediatric Scarlet Fever Medication
- Author: Pamela L Dyne, MD; Chief Editor: Richard G Bachur, MD more...
Medication Summary
Treat patients who have scarlet fever with a standard 10-day course of oral penicillin VK or erythromycin. Patients can also be treated with a single intramuscular injection of penicillin G benzathine. These regimens may prevent acute renal failure if antibiotics are initiated within 1 week of the onset of acute pharyngitis.
Antibiotics
Class Summary
Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting.
Penicillin G benzathine (Bicillin L-A, Beepen-VK, Pen-Vee K)
Inhibits biosynthesis of cell-wall mucopeptide. Bactericidal against sensitive organisms when adequate concentrations reached and most effective during stage of active multiplication. Inadequate concentrations may produce only bacteriostatic effects. If patients have supportive complications, increased doses may be required. May be administered PO as penicillin VK (Beepen-VK, Pen-Vee K) or IM as penicillin G benzathine (Bicillin L-A).
Erythromycin (E.E.S.)
Inhibits bacterial growth, possibly by blocking dissociation of peptidyl t-RNA from ribosomes, causing RNA-dependent protein synthesis to arrest. For treatment of staphylococcal and streptococcal infections. Appropriate therapy for patients allergic to penicillin.
