CONTRACEPTIVES AND MACROLIDES
The macrolides clarithromycin, dirithromycin, roxithromycin and telithromycin appear unlikely to cause combined hormonal contraceptive failure. Isolated cases of contraceptive failure have been attributed to erythromycin or spiramycin. Conversely, in two studies of contraceptive failures in dermatology patients, no pregnancies were identified in a total of 74 women taking erythromycin with oral contraceptives.
