Antibiotics, Oral Contraceptives, and IBD

Briefly noted:

“Physician Knowledge Regarding Concomitant Antibiotic and Oral Contraceptive Use in Patients with IBD.” Gastroenterology & Hepatology 2014; 10: 302-06.

Key finding:

  • IBD specialists and gynecologists were more likely to be aware that no evidence exists to support a link between a decrease in oral contraceptive pill (OCP) efficacy and concomitant use of ciprofloxacin or metronidazole.

Previous studies suggested that antibiotics reduced OCP efficacy.  The authors note that “more recent, prospective, pharmacokinetic studies in women demonstrate no evidence of an interaction between OCPs and most antibiotics, with the exception of rifampin.” (J Am Acad Dermatol 2002; 46: 917-23)
