Reproductive issues pregnancy

On June 24, 1980, the New York Department of Health Commissioner finally issued the Department s epidemiological studies on Adverse Pregnancy Outcomes in the Love Canal Area, concluding that "we have not yet been able to correlate the geographic distribution of adverse pregnancy outcomes with chemical evidence of exposure. At present, there was no direct evidence of cause-effect relationships with chemicals from the Canal." The Commission also concluded that "comprehensive studies of three households with unusually adverse reproductive histories did not produce evidence of unusual risk of chemical exposure."... 

The interactions between the oral contraceptives and tetracyclines summarised here are all that have been identified in the literature. Much of the evidence is anecdotal with insufficient controls (if any). These interactions are not adequately established and the whole issue remains controversial. Bearing in mind the extremely wide use of both drugs, any increase in the incidence of contraceptive failure above the accepted failure rate is clearly very low indeed. On the other hand, the personal and ethical consequences of an unwanted pregnancy can be very serious. For this reason, the Faculty of Family Planning and Reproductive Health Care (FFPRHC) Clinical Effectiveness Unit recommends that an additional form of contraception, such as condoms, should be used while taking a short course of antibacterials that do not induce liver eiKymes, and for 7 days after the antibacterial has been stopped. See Hormonal contraceptives + Antibacterials Penicillins , p.981, for more detailed information on how to manage this interaction.
