Advice needed

Ever tried to give a NASTY medication to a 2 year old?? The generic for a child's Z-pack is disgusting!! Madison refuses to take it and spits it out. I have tried everything. I am at a loss. I even called the doctor to see about an injection, but apparently this is the only medication that works for walking pneumonia. I'm not sure if I should believe this, I guess kids with an allergy to this are just SOL. Apparently e-mycin can be used sometimes, but they say it tastes worse than the z-pack. I don't know what to do. We even had a second bottle called in and flavored, no luck though. They ay there isn't a shot for this either. What should I do?? We are waiting for the doctor to call me back any minute now...
