564:. They are best avoided in the athlete population. Safety concerns exist for fluoroquinolone use during pregnancy, so they are contraindicated unless no other safe alternative antibiotic exists. However, one meta-analysis looking at the outcome of pregnancies involving quinolone use in the first trimester found no increased risk of malformations. They are also contraindicated in children due to the risks of damage to the musculoskeletal system. Their use in children is not absolutely contraindicated, however for certain severe infections where other antibiotics are not an option, their use can be justified. Quinolones should also not be given to people with a known 184: 1384:
effects occurring at the same time and causing the potential for irreversible impairment. The advisory committee concluded that the serious risks associated with the use of fluoroquinolones for these types of uncomplicated infections generally outweighed the benefits for patients with other treatment options. The 21-member joint committee overwhelmingly recommended stronger label warnings on the containers because of rare but sometimes devastating side effects.

On 12 May 2016, the FDA issued a drug safety communication advising that fluoroquinolones should be reserved for these conditions only when no other options are available due to potentially permanent, disabling side effects occurring together. The drug safety communication also announced the required

These drugs were widely used as a first-line treatment for many infections, including very commons ones such as acute sinusitis, acute bronchitis, and uncomplicated UTIs.

From 1995 to 2002, inappropriate antibiotic prescribing for acute respiratory infections, which are usually caused by viruses and thus are not responsive to antibiotics, declined from 61 to 49 percent. However, the use of broad-spectrum antibiotics such as the fluoroquinolones, jumped from 41 to 77

Quinolones are associated with a small risk of tendonitis and tendon rupture; a 2013 review found the incidence of tendon injury among those taking fluoroquinolones to be between 0.08 and 0.20%. The risk appears to be higher among people older than 60 and those also taking corticosteroids; the risk
