B.S.
If shes not penicillin allergic, I would take h er back to the doctor and ask for LA Bicillin injection. No oral medicine required. Just one quick injection and less trama to the good gut flora which are altered with the oral meds. It works faster too. My children suffered with strep and my daughter had scarlet fever too (strep with the rash). Hope all goes well,
