Cipro is in the group of antibiotics called fluoroquinolones, and it used to fight bacteria in the body. Cipro has been used to treat bacterial infections, and has even been known to prevent or slow anthrax after exposure. Cipro, which is generically known at Ciprofloxacin, was developed by Bayer, A.G. Cipro was patented in 1983 and was approved by the FDA in 1987. The FDA approved Cipro for 12 different uses, but it has been prescribed for a variety of unapproved uses.
The FDA added a black box warning in 2011 that stated that fluoroquinolones may cause the worsening of myasthenia gravis symptoms—such as muscle weakness and breathing problems. This reaction may be life-threatening or require ventilator support.
Bayer has been accused of false advertising and failing to provide adequate warnings to consumers about the risks that are involved with taking Cipro.
