Amoxicillin Side Effects in Children

Stomach pain, nausea and diarrhea are some of the common side effects of amoxicillin observed in children.
Although amoxicillin works to cure common bacterial infections in children, it can cause side effects, some of which can be quite serious.

Side Effects

In most cases, children put on an amoxicillin dose do not usually suffer from any serious side effects. Also, the side effects that occur after taking the medicine go away within a few days without any medical intervention. They are listed below:
  • Diarrhea
  • Nausea
  • Abdominal pain
  • Vomiting
The child may experience few episodes of diarrhea during the antibiotic treatment. As a parent, it is naturally for you to get worried. However, the diarrhea usually stops in a day or two. With the onset of diarrhea, the desire to eat food may also reduce substantially. However, if the diarrhea aggravates over time and lasts for more than 3 to 4 days, it is advised to talk to a doctor.


Allergic Reaction: Amoxicillin rash during the antibiotic treatment is an indication that the child is allergic to this medication. This is a mild allergic reaction, yet immediate consultation with the doctor is a must. Rash in the form of hives usually affects the facial area. Hives manifest as blistered areas that itch terribly and sometimes occur after completing the antibiotic course.

However, if it is a serious reaction, the lips, cheeks and the tongue may swell suddenly. This may be accompanied by the inability to breathe and talk properly.

Other severe side effects that may occur are mentioned below:
  • Confusion or dizziness
  • Bleeding
  • Bruising
  • Skin turns yellow (jaundice)
  • Blood in stool
Children with asthma and skin problems like eczema are advised to stay away from amoxicillin as they are found to be more sensitive to this medicine. In some cases, the antibiotic may not be effective in eliminating infections in children and in such a scenario the doctor may prescribe medications like Benadryl.
