Suspect That 3 1/2 Yr I'd Granddaughter May Have Either

Suspect that 3 1/2 yr I'd granddaughter may have either rheumatic fever and/or allergic reaction or side affect from amoxicillin. Do you have capabilities to call out addl rx if deemed necessary!? I called the phone number listed assoc w/USA to ask about paying without purchasing a package, just a one time fee, unable to understand the person answering the calls..for this reason I will not be using the service at this time. Thank you
