My 1 yo has been on zpack since sun. Still has fever. This is 3rd ear infect in 3.5 mo & its a double. What should I do? Ent? Call md in morn

Don't panic. Use the zmax for 2 more days--if still feverish may need to switch to a different antibiotic--it sometimes takes 72-96hrs of treatment to show improvement.
Call md in morn. Persistence of fever over 48 hours after the initiation of antibiotics suggests bacterial resistance. Z pack (azithromycin) is not a good choice for ear infection in infant.
