Relevance: 12.11.2023 Reviewer: Shkutko P.M., M.D., in

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.

Consumer:

Talk to your doctor before using warfarin and ethinyl estradiol. This combination may reduce the effects of warfarin. Call your doctor promptly if you have any signs of blood clots such as chest pain, shortness of breath, sudden loss of vision, or pain, redness or swelling in an extremity. It is important that you tell your healthcare provider about all other medications that you are using including vitamins and herbs. Do not stop using your medications without talking to your doctor first.

Professional:

GENERALLY AVOID: Concomitant therapy with estrogen-containing drugs may diminish the therapeutic effects of oral anticoagulants. Estrogens can increase the plasma levels of certain clotting factors such as fibrinogen, prothrombin, and factors VII and VIII in a dose-dependent manner, resulting in increased risk of thromboembolism, stroke, and/or myocardial infarction. The risk may be further increased by lifestyle choices such as smoking and lack of exercise.

MANAGEMENT: Use of estrogen-containing drugs should be avoided in patients receiving anticoagulant therapy unless benefits are anticipated to outweigh the risks. Close clinical and laboratory monitoring are recommended if the combination is prescribed. Patients should be advised to promptly notify their physician if they experience potential signs and symptoms of blood clots such as chest pain, shortness of breath, sudden loss of vision, and pain, redness or swelling in an extremity.
