There is an increased risk of aortic aneurysm and dissection following treatment with ofloxacin. Use ofloxacin only after careful benefit risk assessment in patients with positive family history of aneurysm disease, or in patients diagnosed with pre-existing aortic aneurysm and or aortic dissection, or in the presence of other risk factors or conditions predisposing for aneurysm and dissection (e.g. Marfan syndrome, vascular Ehlers-Danlos syndrome, Takayasu arteritis, giant cell arthritis, Behcet's disease, hypertension, known atherosclerosis.)
Disabling, long-lasting and potentially irreversible adverse reactions mainly affecting musculoskeletal and nervous systems have been reported with quinolone and fluoroquinolone antibiotics. Treatment should be discontinued at the first signs of a serious adverse reaction such as tendinitis, pain or inflammation.
Pregnancy and Lactation
Pregnancy
Ofloxacin is contraindicated during pregnancy.
The manufacturer does not recommend using ofloxacin during pregnancy.
Based on limited amount of human data, the use of fluoroquinolones in the first trimester of pregnancy has not been associated with an increased risk of major malformations or other adverse effects on pregnancy outcome.
Ofloxacin has been shown to cause arthropathy in immature animals. Reproduction studies in rats and rabbits did not reveal any evidence of teratogenicity, impairment of fertility or impairment of peri- and post-natal development. Animal studies do not entirely exclude the risk of damage to the cartilage of joints in the growing subject.
Schaefer (2015) suggests quinolones should only be used in case of complicated infections resistant to the antibiotics of choice in pregnancy. Ciprofloxacin and norfloxacin have a relatively large amount of documented experience. Even the first trimester use of a quinolone antibiotic is not an indication for termination of pregnancy, but detailed foetal ultrasonography can be offered.
The use of all medication in pregnancy should be avoided whenever possible; particularly in the first trimester. Non-drug treatments should also be considered. When essential, a medication with the best safety record over time should be chosen, employing the lowest effective dose for the shortest possible time. Polypharmacy should be avoided. Teratogens taken in the pre-embryonic period, often quoted as lasting until 14 to 17 days post-conception, are believed to have an all-or-nothing effect. Where drugs have a short half-life, and when the date of conception is certain, this may allow women to be reassured where drug exposure has occurred within this time frame.

Lactation
Ofloxacin is contraindicated during breastfeeding.
The manufacturer does not recommend breastfeeding whilst taking ofloxacin.
Quinolones have been shown to cause arthropathy in animal studies.
Ofloxacin is excreted into breast milk in concentrations similar to those in maternal serum. Avoiding breastfeeding for 4 to 6 hours after a dose should decrease the exposure of the infant to ofloxacin in breast milk.
Schaefer (2015) suggests as a rule, a standard antibiotic with a lower potential for risk can be substituted for the use of quinolones.
Neonates, infants born prematurely, those with low birth weight, those with an unstable gastrointestinal function or who have serious illnesses may require special consideration. For any infant, if a drug is prescribed to the nursing mother, it should be at the lowest practical dose and for the shortest time. When drug administration is unavoidable and breastfeeding is to continue, minimisation of exposure of the infant to the drug may sometimes be achieved by timing the maternal doses to just after a feeding episode. Infants exposed to drugs via breast milk should be monitored for unusual signs or symptoms. Interactions between the drug received by the infant from the mother's milk and medication prescribed for the infant should also be considered, for example, when the drug given to the infant may prevent metabolism of the drug received via breast milk.

Effects on Laboratory Tests
Determination of opiates in urine may give false positive results during treatment with ofloxacin. The use of more specific methods may be necessary to confirm positive opiate screens.
Overdosage
It is strongly recommended that the UK National Poisons Information Service be consulted on cases of suspected or actual overdose where there is doubt over the degree of risk or about appropriate management.
