My 4 yr.old son has had hives on his face now for 8 mo. we have gone to his dr. and a child skin doctor and he put him on Amoxil for one month along with zertex. They are only on his face and he does not even know they are there and they only pop out in the morning when he wakes up or naps. Dr, thought it could have been a sinus infection that he never got rid of. I am so happy they don\'t bother him. I really hope this med helps him. First he was on claritan but the hives would still come out. I bought new pillows for his bed, new sheets changed to Tide Free Watched what he ate. eight months is enought if this does\'nt work We\'ll have to get a scratch test next.
