My son suffered symptom s like schizophrenia after 3 different doctors prescribed ciproflaxin for 3 different types of bacteria infections. He has never been the same. I m tired of doctors saying this was not the cause. This antibiotic is dangerous. My son had no problems until he took this medication. After my son s break, I called his last doctor to inquire about this drug, they acted like I didn t know what I was talking about. When I was a care giver for my Mom, I was able to distinguish what medicines made her delusional and was able to stop giving her the medicine. I didn t think I had to follow my son like that. Every negative psychotic side effect on the drug package was realized with my son. I don t know how many years it is going to take him to recover. After this happened, I found out that other people had serious neurological effects from this drug, including one author who wrote the book, Bitter Pill . We tried a year of psychiatry, the drugs only made it worse. He has been 2 years without drugs, just supplements. This drug affects more than tendons.
