Papers documenting mechanistic interactions between antibiotics and oral contraceptives were included. Rifampin is the only antibiotic that has been reported to reduce plasma estrogen concentrations.
As a result, parts of the site may not function properly for you. Clin Pharmacokinet. If you need to take a painkiller while you're taking azithromycin it's fine to take paracetamol or ibuprofen.

Women of childbearing Zithronax commonly receive azithromycin for the Zithromax and oral contraceptives of community-acquired infections, including during Zithromax and oral contraceptives. This study determined azithromycin pharmacokinetics in pregnant and nonpregnant women and identified Zithromax and oral contraceptives contributing to pharmacokinetic variability. Plasma contracpetives were collected by using a sparse-sampling strategy from pregnant women at a gestational age of 12 to 40 weeks and from nonpregnant women of childbearing age receiving oral azithromycin for the treatment of an infection.
Pharmacokinetic data from extensive sampling conducted on 12 healthy women were also included. Plasma samples were assayed for azithromycin by high-performance Video lycra bulges chromatography.
Population data were analyzed by nonlinear mixed-effects modeling. The population analysis included 53 pregnant and 25 nonpregnant women. A three-compartment model with first-order absorption and a lag time provided the best fit of the data. Lean body weight, pregnancy, ethnicity, and the coadministration of Rubber band gun blue print contraceptives were covariates identified as significantly influencing the oral clearance of azithromycin and, except for oral contraceptive use, intercompartmental clearance between the central and second peripheral compartments.
No other covariate relationships were identified. Conversely, azithromycin AUCs were similar between pregnant African American women and nonpregnant women not receiving oral contraceptives.
Although higher levels of maternal and fetal azithromycin exposure suggest that lower doses be administered to non-African American women during pregnancy, the consideration of azithromycin pharmacodynamics during pregnancy should guide any dose adjustments.
