Where can I get advice and support? 

There’s a large online community of people sharing their stories and experiences through forums, websites and Facebook groups. So large, in fact, that the term ‘Floxing’ has been coined to describe the adverse events that can occur during or after taking one of these antibiotics. Floxing is also commonly referred to as Fluoroquinolone Toxicity, FQ Toxicity, or FQTS. The term Fluoroquinolone-Associated Disability or FQAD is a term used to refer to those affected with chronic, long-lasting disability caused by multiple symptoms.  

Although you should take care not to take medical advice from people who are not medical professionals, it can be helpful to connect with others who are in a similar situation to you, and to hear about their journeys.
