Interactions between your drugs

Moderate

ciprofloxacin ethinyl estradiol

Applies to: Cipro (ciprofloxacin) and Quartette (ethinyl estradiol / levonorgestrel)

Antibiotics such as ciprofloxacin may reduce the effects of ethinyl estradiol in some women. If you are using ethinyl estradiol for birth control, you may be at increased risk for pregnancy or breakthrough bleeding. Talk to your healthcare provider to determine if you should use an alternative or additional form of birth control during treatment with ciprofloxacin. In addition, some birth control preparations may include "placebo" non-hormonal pills that contain iron. If you are taking these iron pills during treatment with ciprofloxacin, you should separate the dosing times by several hours so that the iron does not interfere with absorption of the antibiotic. Ask your doctor or pharmacist for information on when best to take these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Do not take ciprofloxacin with dairy products such as milk or yogurt, or with calcium-fortified foods (e.G., cereal, juice).
