Fluoroquinolones are associated with disabling and potentially irreversible serious adverse reactions from different body systems, including tendinitis, tendon rupture, arthralgia, myalgia, peripheral neuropathy, and CNS effects (eg, hallucinations, anxiety, depression, insomnia, severe headaches, confusion)

Risk of tendinitis and tendon rupture in all ages; the Achilles tendon is most frequently involved, but rupture has also been reported with the rotator cuff, hand, biceps, thumb, and other tendons

Fluoroquinolones are associated with increased risk of peripheral neuropathy; sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias, and weakness reported

Fluoroquinolones elicit neuromuscular blocking activity and may exacerbate muscle weakness with myasthenia gravis

Serious and occasional fatal hypersensitivity reactions (including after first dose) reported

Clostridium difficile-associated diarrhea (CDAD) reported with use of nearly all systemic antibiotics

Prescribing an antibiotic in the absence of proven or strongly suspected bacterial infection is unlikely to provide benefit and increases risk developing drug-resistant bacteria

Increased risk of aortic aneurysm and dissection within 2 months following fluoroquinolone use observed in epidemiologic studies, particularly in elderly patients; etiology has not been identified; reserve use in patients with known or at greater risk for aortic aneurysm only when there are no alternative antibacterial treatments available

Blood glucose disturbances reported with fluoroquinolones, including symptomatic hyperglycemia and hypoglycemia, usually in diabetic patients receiving concomitant treatment with an oral hypoglycemic agent (eg, glyburide) or with insulin; careful blood glucose monitoring recommended; severe cases of hypoglycemia resulting in coma or death reported with other fluoroquinolones
