my 19-month old son has an ear infection and was prescribed amoxicillan.  This is the 3rd time that hes had this medication.  suddenly on the 7th day of taking this drug (the 3rd time) he broke out in hives and his face swelled up.  could he have just recently developed an allergic reaction eventhough this isnt the first time taking this medicine??  he also had chills tonight.
Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint it seems that your son had an allergic reaction to the antibiotic given to you leading to rashes and swelling. It is one of the common presentation of allergy to antibiotic that leads to rashes and swelling. Many a time there is a delayed allergic reaction as the antibodies against a specific allergen are gradually formed in the body and once they are sufficient in concentration they try to fight against the allergen leading to the symptoms. You should also immediately give him the antibiotics and consult your treating physician and get evaluated, and he can give him anti allergic like Ben Chat Doctor. . Doing cool compresses and applying Calamine lotion can also help. Give plenty of water to wean off the effect of the allergen faster by increasing the excretion through urine. Hope this information helps. Thanks and regards.
