Augmentin is a strong drug used to treat many different infections caused by bacteria, such as sinusitis, pneumonia, ear infections, bronchitis, urinary tract infections, and infections of the skin by killing the bacteria in your body.
Your baby has been prescribed to take the medicine because he/she needs it to be treated. However, for some patients, Augmentin has side effects on them. One of the symptoms are the development of rashes.
You should visit your doctor as soon as possible to check if these rashes are indeed brought by the medicine. If it is, your doctor must advise you to discontinue the use of Augmentin and prescribe you with another drug.
Hope your baby will get better soon.
