Listed in Public Citizen as a Do Not Use Limited Use drug
Numerous other, safer antibiotics are approved to treat the same infections as this drug.


In October of 2004 new warning labels added to the fluoroquinolones regarding Peripheral Neuropathy (irreversible nerve damage), Tendon Damage (spontaneous tendon ruptures), Heart Problems (prolonged QT Interval / Torsades de pointes), Pseudomembranous colitis, Rhabdomyolysis (muscle wasting), Steven Johnson Syndrome, as well as concurrent usage of NSAIDs.

Peripheral Neuropathy
Rare cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving quinolones.

 

QUINOLONES MAY HAVE THE POTENTIAL TO PROLONG THE QTc INTERVAL OF THE ELECTROCARDIOGRAM IN SOME PATIENTS. DUE TO THE LACK OF CLINICAL EXPERIENCE, GATIFLOXACIN SHOULD BE AVOIDED IN PATIENTS WITH KNOWN PROLONGATION OF THE QTc INTERVAL, PATIENTS WITH UNCORRECTED HYPOKALEMIA, AND PATIENTS RECEIVING CLASS IA (E.G. QUINIDINE, PROCAINAMIDE) OR CLASS III (E.G. AMIODARONE, SOTALOL) ANTIARRHYTHMIC AGENTS.

Ruptures of the shoulder, hand, and Achilles tendons that required surgical repair or resulted in prolonged disability have been reported in patients receiving quinolones. Tendon rupture can occur during or after therapy with quinolones.

Quinolones may cause central nervous system (CNS) events including nervousness, agitation, insomnia, anxiety, nightmares, or paranoia.

As with other quinolones, disturbances of blood glucose, including symptomatic hyper- and hypoglycemia, have been reported, usually in diabetic patients receiving concomitant treatment with an oral hypoglycemic (e. g., glyburide) or with insulin. In these patients, the monitoring of blood glucose is recommended.


FLOXIN (ofloxacin) and FLOXIN I.V. (ofloxacin)
[Safety Label changes, September 11, 1996: R.W. Johnson]

WARNINGS:
The second paragraph detailing severe and sometimes fatal events that have been reported in patients receiving quinolones, including ofloxacin, has been revised to indicate that some of these events are due to hypersensitivity, with those occurring with ofloxacin treatment no longer characterized as extremely rare.
A new paragraph has been added that indicates the reporting of ruptures of the shoulder, hand and Achilles tendons that required surgical repair or resulted in prolonged disability with ofloxacin and other quinolones. Ofloxacin should be discontinued if pain, inflammation or tendon rupture is experienced by the patient, who should rest and refrain from exercise until the diagnosis of tendonitis or tendon rupture has been confidently excluded. Tendon rupture can occur at any time during or after therapy with ofloxacin.
The paragraph concerning syphilis and gonorrhea with respect to ofloxacin treatment has been revised to indicate that those patients treated with ofloxacin for gonorrhea who have a positive follow-up serologic test for syphilis after three months should be treated with an appropriate antimicrobial.
 
PRECAUTIONS:
Information for Patients: Section has been revised thusly: The statement that cautioned against taking mineral supplements, vitamins with iron or minerals, calcium-, aluminum- or magnesium-based antacids or sucralfate within two hours before or after ofloxacin has been removed.
The statement that ofloxacin can be taken without regard to meals has been removed.
A new statement has been added that indicates patients should be advised that ofloxacin treatment is to be discontinued and their physician informed if they experience pain, inflammation or tendon rupture, and to rest and refrain from exercise until the diagnosis of tendonitis or tendon rupture has been confidently excluded.
A new statement has been added that indicates the reporting of convulsions in patients taking quinolones, including ofloxacin, and that patients are to notify their physician before taking ofloxacin if they have a history of this condition

Adverse Drug reactions associated with Ofloxacin:

Peripheral neuropathy: Rare cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paresthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving quinolones, including ofloxacin. Ofloxacin should be discontinued if the patient experiences symptoms of neuropathy including pain, burning, tingling, numbness, and/or weakness or other alterations of sensation including light touch, pain, temperature, position sense, and vibratory sensation in order to prevent the development of an irreversible condition.

Convulsions, increased intracranial pressure, and toxic psychosis have been reported in patients receiving quinolones, including ofloxacin. Quinolones, including ofloxacin, may also cause central nervous system stimulation which may lead to: tremors, restlessness/agitation, nervousness/anxiety, lightheadedness, confusion, hallucinations, paranoia and depression, nightmares, insomnia, and rarely suicidal thoughts or acts. These reactions may occur following the first dose.

Achilles and other tendon ruptures that required surgical repair or resulted in prolonged disability have been reported with quinolones. Post-marketing surveillance reports indicate that the risk may be increased in patients receiving concomitant corticosteroids, especially in the elderly.  The systemic administration of quinolones, including ofloxacin, has led to lesions or erosions of the cartilage in weight-bearing joints and other signs of arthropathy in immature animals of various species.

Ophthalmologic abnormalities, including cataracts and multiple punctate lenticular opacities, have been noted in patients undergoing treatment with other quinolones.

CRYSTALLURIA and CYLINDRURIA HAVE BEEN REPORTED with quinolones.

Non-steroidal anti-inflammatory drugs: The concomitant administration of a non-steroidal anti-inflammatory drug, with a quinolone, including ofloxacin, may increase the risk of CNS stimulation and convulsive seizures.

Serious and occasionally fatal hypersensitivity (anapHylactic/anapHylactoid) reactions have been reported in patients receiving therapy with quinolones, including ofloxacin. These reactions often occur following the first dose. Some reactions were accompanied by cardiovascular collapse, hypotension/shock, seizure, loss of consciousness, tingling, angioedema (including tongue, laryngeal, throat or facial edema/swelling, etc.), airway obstruction (including bronchospasm, shortness of breath and acute respiratory distress), dyspnea, urticaria/hives, itching, and other serious skin reactions.

Serious and sometimes fatal events of uncertain etiology have been reported in patients receiving therapy with quinolones including, extremely rarely, ofloxacin. These events may be severe and generally occur following the administration of multiple doses. Clinical manifestations may include one or more of the following: fever, rash or severe dermatologic reactions (e.g., toxic epidermal necrolysis, Stevens- Johnson Syndrome, etc.); vasculitis, arthralgia, myalgia, serum sickness; allergic pneumonitis; interstitial nepHritis, acute renal insufficiency/failure; hepatitis, jaundice, acute hepatic necrosis/failure; anemia including hemolytic and aplastic, thrombocytopenia, including thrombotic thrombocytopenic purpura, leukopenia, agranulocytosis, pancytopenia, and/or other hematologic abnormalities.

Moderate to severe phototoxicity reactions have been observed in patients exposed to direct sunlight while receiving some drugs in this class, including ofloxacin.

As with other quinolones, disturbances of blood glucose, including symptomatic hyper- and hypoglycemia, have been reported.


Pregnancy Warning

Ofloxacin and moxifloxacin caused fetal harm in animal studies, including decreased fetal body weight and increased death when given by mouth. Because of the potential for serious adverse effects to the fetus, these drugs should not be used by pregnant women unless there is no safer substitute.

Breast-feeding Warning

These drugs are excreted in human milk. Because of the potential for serious adverse effects in nursing infants, you should not take these drugs while nursing.
