Abiraterone (Zytiga) is a medicine used with prednisone to treat prostate cancer that has spread. It works by lowering the amount of androgen your body makes.
Iclevia is a birth control pill. It contains two hormones, levonorgestrel and ethinyl estradiol, to prevent pregnancy.
Abiraterone is used to treat prostate cancer that has spread to other parts of the body. It is for cancers that are castration-resistant, meaning they no longer respond to hormone therapy alone. It is also used for high-risk castration-sensitive prostate cancer. You will take this medicine with prednisone.
Iclevia is used by women who can get pregnant to prevent pregnancy. It contains two hormones, a progestin and an estrogen. These hormones work together to prevent ovulation and change the lining of the uterus.
Abiraterone blocks an enzyme called CYP17, which your body needs to make androgens. Androgens can help prostate cancer grow. By blocking this enzyme, abiraterone lowers androgen levels and slows cancer growth.
Iclevia contains two hormones: levonorgestrel and ethinyl estradiol. These hormones prevent ovulation (the release of an egg from the ovary). They also change the lining of the uterus, making it harder for a fertilized egg to implant.

Abiraterone can cause problems with mineralocorticoid excess, like high blood pressure, low potassium, and fluid retention. If you have heart problems, your doctor will monitor you closely. This medicine can also cause liver problems, which can be severe. Your doctor will check your liver function regularly. Do not take abiraterone with radium Ra 223 dichloride. Abiraterone can harm an unborn baby, so men should use effective birth control if their partner can get pregnant.
Cigarette smoking increases your risk of serious heart problems from birth control pills. This risk is higher if you are over 35 and smoke more cigarettes. If you are over 35 and smoke, you should not take Iclevia.
Abiraterone can cause harm to an unborn baby. Men who are taking abiraterone should use effective birth control during treatment and for 3 weeks after the last dose if their partner is able to get pregnant. It is not known if abiraterone passes into breast milk.
Do not use Iclevia if you are pregnant. Iclevia can reduce milk production while breastfeeding, so another form of birth control is recommended. Talk to your doctor about the best option for you.

How to Read This abiraterone vs ethinyl estradiol/norgestimate Comparison
abiraterone is classified in the CYP17 Inhibitor drug class, while ethinyl estradiol/norgestimate sits within the Combined Oral Contraceptive class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, abiraterone has 4,213 submissions while ethinyl estradiol/norgestimate has 0. Those figures reflect cumulative reporting volume — not per-patient risk — so older, widely dispensed drugs typically look worse on count alone. No direct interaction between these two drugs is listed in our FDA-derived dataset, though co-prescription still warrants pharmacist review. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This page is for educational purposes only, is not medical advice, and should not be used to self-switch between abiraterone and ethinyl estradiol/norgestimate — always consult your physician or pharmacist first.
