CIPRO (Ciprofloxacin)
|
· Animal reproduction studies have not shown arthropathy or other musculoskeletal problems in offspring exposed to ciprofloxacin in utero2. · While no clinical studies have been conducted in pregnant women, controlled prospective observational data suggest that in utero exposure to fluoroquinolones is not associated with clinically significant major musculoskeletal dysfunctions9. · Seven women exposed to ciprofloxacin during second or third trimester delivered healthy normal babies. Motor, adaptive, social, and language milestones in each child were consistent with age, and no evidence of cartilage damage was found on regular clinical assessments up to five years of age10. | |
Other Teratogenic Effects and Outcomes |
· Animal reproduction studies in mice, rats, and rabbits have revealed no evidence of teratogenicity in offspring exposed to ciprofloxacin in utero2. Studies in pregnant monkeys did not produce detectable adverse effects on embryonic or fetal development11. · Controlled prospective observational data on 200 fluoroquinolone-exposed human pregnancies (52.5% exposed to ciprofloxacin and 68% treated during the first trimester) showed the rate of major malformations among live-born children exposed during the first trimester was in the expected normal range of 1 - 5% as was the rate in controls. There were no differences in the rates of prematurity, spontaneous abortions, or birth weight9. · Non-controlled prospective observational data on 70 ciprofloxacin-exposed human pregnancies (60% exposed during the first trimester) showed the rate of congenital malformations in live-born children exposed during the first trimester was 4.7%. The frequencies of spontaneous abortion/fetal death, post-natal disorders, prematurity and intra-uterine growth retardation did not exceed background rates12. · In a company-sponsored prospective registry of 116 human pregnancies, 54% were exposed during the 1st trimester and resulted in live births. Of these, six were malformed. There was no pattern of anomalies seen among the reported spectrum of minor and major malformations12. |
Other Teratogenic Effects and Outcomes (cont'd) |
· An observational cohort study looking at human experience with five different antibiotics reported a total of 40 pregnancies with ciprofloxacin. Five of the nine women who received ciprofloxacin during the first trimester experienced normal births with no reported congenital abnormalities. The other four first trimester exposures were an ectopic pregnancy, a spontaneous abortion and two terminations13. · One publication described six pregnant women exposed to longer durations of ciprofloxacin therapy (3 weeks to 3 months) who delivered normal babies14. There has also been a case report of a pregnant woman exposed to three weeks of ciprofloxacin therapy during early third trimester who delivered a normal baby15. |
Duration of Exposure |
· The vast majority of reported experience with ciprofloxacin during human pregnancy (as described above) is short-term, 1st trimester exposure. |
