Lynparza and Microgestin Fe 1/20

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Olaparib may reduce the blood levels and effects of ethinyl estradiol. If you are using birth control pills or another hormone-type contraceptive such as a patch, shot, vaginal ring or implant, you should talk to your doctor before taking olaparib. You may need an alternative or additional method of birth control during treatment with olaparib in order to avoid an unintended pregnancy. Let your doctor know if you experience bleeding outside of your menstrual cycle, since it may indicate reduced effectiveness of ethinyl estradiol. 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.

ADDITIONAL CONTRACEPTION RECOMMENDED: Coadministration with olaparib may decrease the plasma concentrations and efficacy of contraceptive hormones. The proposed mechanism is olaparib induction of CYP450 3A4, the isoenzyme primarily responsible for the metabolic clearance of sex hormones. Clinical data are lacking.

MANAGEMENT: Some authorities recommend that women avoid pregnancy during olaparib treatment due to its potential teratogenic effects. In women of childbearing potential, alternative or additional non-hormonal methods of birth control should be considered during treatment and for one month after receiving the last dose of olaparib. Regular pregnancy tests are also recommended. Intrauterine systems are unlikely to be significantly affected because of their local action. Input from a gynecologist or similar expert on adequate contraception, including emergency contraception, should be sought as needed.
