[2014] How I Gave My Son Autism  Antibiotics – Oh boy. Where to begin? I have so many mixed feelings about antibiotics. Here is what I know: My son was exposed to antibiotics while he was in distress during labor. He was then exposed for the first two weeks of his life via breast milk. He then received five courses of antibiotics before he was a year old for chronic ear infections. While this is bad cumulatively, the one event that stands out for me, and literally makes me feel sick, was a single dose of Augmentin when he was six months old. At his six-month “well” visit, he was diagnosed with his second ear infection. He received vaccinations for seven different diseases despite being ill, and we left with a prescription for Amoxicillin. Six days later, he had developed an upper respiratory infection and the ear infection was worse. Because the Amoxicillin hadn’t worked, the pediatrician prescribed a course of Augmentin. After one dose of this drug and within 24 hours, my six-month-old baby had 35 acidic, liquid bowel movements. The skin literally peeled off of his bottom in sheets. I had never seen anything like it at that time, and I haven’t since. The pain that he was in was beyond description. I called the doctor and she changed the antibiotic to yet a different kind. So he had three different types of antibiotics in his system within eight days. This episode was the biggie. His gut was never the same after that. Nothing was.
    Here is what everyone should know about Augmentin:  Augmentin has been implicated in autism.  It is comprised of Amoxicillin and clavulanate potassium. When it is manufactured, the clavulanic acid is fermented which involves large amounts of urea/ammonia. Even a small amount of ingested ammonia can potentially cause gut and brain inflammation. I strongly urge you to do your homework before using this drug.
    If you will notice in this link, this study was released in January of 2005. My son was prescribed Augmentin in January of 2006. This was never mentioned when I was handed the prescription. However, if I had been a Thinker back then, I could have quickly Googled “Augmentin and autism,” and I would have made a very different decision.

[2008] Antibiotics and Autism By Kent Heckenlively, Esq.   prior to the development of autism, many of our children had multiple ear infections, which were then treated with antibiotics.  Many parents believe the antibiotic treatment in some way set the stage for their child’s autism.  I know that my own daughter had several ear infections in her first year of life which were treated with antibiotics.

[2005] Could one of the most widely prescribed antibiotics amoxicillin/clavulanate "augmentin" be a risk factor for autism?   These children were found to have a mean number 9.96 bouts of otitis media (with a standard error of the mean of +/-1.83). This represents a sum total for all 206 children of 2052 bouts of otitis media. These children received a mean number of 12.04 courses of antibiotics (standard error of the mean of +/-.125). The sum total number of courses of antibiotics given to all 206 children was 2480.
