Product Details

NuvaRing (Etonogestrel/Ethinyl Estradiol) Vaginal Ring

NuvaRing (Etonogestrel/Ethinyl Estradiol) Vaginal Ring

NuvaRing is a prescription hormonal contraceptive used to prevent pregnancy in females of reproductive age or individuals with a uterus. It’s a flexible plastic ring that you insert into the vagina, where it continuously releases two hormones, etonogestrel and ethinyl estradiol, that help stop ovulation and make it harder for sperm to reach the egg. Like other hormonal contraceptives, NuvaRing does not protect against STIs and may increase the risk of blood clots in some users. Talk with your doctor to decide whether NuvaRing is right for you to avoid any potential side effects.

What Are the Pros and Cons of NuvaRing?

What Are the Pros and Cons of NuvaRing?

Pros:

Many people prefer vaginal ring birth control options over pills due to their convenience. Here’s a list of reasons why some people choose NuvaRing to prevent pregnancy:

  • When used perfectly, NuvaRing is over 99% effective.
  • It may make your periods lighter, shorter, and more regular.
  • Etonogestrel and ethinyl estradiol may help clear skin in those prone to hormonal acne.

Cons:

However, like any contraceptive method, it does come with specific side effects:

  • The ring does not protect against HIV or other sexually transmitted infections.
  • Some users may experience symptoms like mood swings or depression.
How Effective Is NuvaRing?

How Effective Is NuvaRing?

The NuvaRing is highly effective when used correctly, but its effectiveness may be reduced due to human error. According to the CDC, NuvaRing effectiveness rates are measured in two ways: perfect use (clinical conditions) and typical use (real-world conditions). The report shows:

  • Perfect Use (>99% effective): If the ring is inserted, removed, and replaced exactly as directed, the NuvaRing failure rate is approximately 0.3%. This means less than 1 in 100 women will become pregnant in a year.
  • Typical Use (91%–93% effective): In real-world scenarios, where a user might forget to change the ring on time, or it remains out of the body for too long, the NuvaRing failure rate is approximately 7–9%. This means about 7 to 9 out of 100 women may become pregnant each year.

The effectiveness of vaginal ring contraceptives, including NuvaRing, depends largely on using the ring on schedule.

How Do You Insert NuvaRing?

How Do You Insert NuvaRing?

If you are inserting the NuvaRing birth control ring for the first time, follow these steps:

  • Wash your hands thoroughly with soap and water.
  • Hold and pinch the ring between your thumb and forefinger.
  • Insert it deep into your vagina until it feels comfortable.
  • Once correctly positioned, you should not feel the ring.
  • Leave it in place for 3 weeks, then remove it and have a 1‑week ring‑free interval before inserting a new ring.

What to Do If NuvaRing Falls Out?

If the ring slips out and has been out for less than 3 hours, rinse it with cool water and reinsert it. If more than 3 hours, extra contraception (e.g., condoms) may be needed until the ring has been in place 7 days in a row. Check the ring’s presence regularly before/after intercourse and know when to reinsert if expelled. Ask your provider about expected withdrawal bleeding during the off week.

How Does the NuvaRing Work?

How Does the NuvaRing Work?

NuvaRing is a hormonal contraceptive that contains two hormones, etonogestrel (a progestin) & ethinyl estradiol (an estrogen). When inserted into the vagina, the ring releases these hormones continuously over a three-week period. This combined hormonal contraceptive works in several ways to prevent pregnancy.

  • First, it stops the ovaries from releasing an egg (ovulation).
  • Second, it thickens the cervical mucus, making sperm movement through the cervix more challenging.
  • Finally, it alters the uterine lining, reducing the likelihood that a fertilized egg will implant.

By working through these steps, NuvaRing provides highly effective contraception when used as directed.

What Are the Possible Side Effects of the NuvaRing?

What Are the Risks of the NuvaRing?

NuvaRing (etonogestrel ethinyl/estradiol vaginal ring) is considered safe for most women when used as directed. However, like all combined hormonal contraceptives, there are some safety considerations. Here are some NuvaRing warnings that every user must be mindful of when using this vaginal birth control ring:

  • Do not use if you smoke and are over 35 years old due to serious cardiovascular risk.
  • It is not recommended for people with a medical history of heart attack, blood clots, or stroke.
  • Avoid using a vaginal birth control ring if you have uncontrolled high blood pressure, liver disease, or certain cancers like breast or uterine cancer.
  • Do not use if you are pregnant or planning a pregnancy.
  • Some medications may reduce the effectiveness of combined hormonal contraceptives. Discuss all medicines with your doctor.
  • Some users may have a higher clot risk due to the specific progestin in NuvaRing compared with certain low-dose birth control pills.
  • Diabetic patients who already have damaged kidneys, eyes, nerves, or blood vessels are at high risk of serious complications with CHC.
  • NuvaRing does not protect against HIV, AIDS, or other sexually transmitted infections. Use a reliable barrier method to reduce the risk of STIs.
  • Rarely, NuvaRing users may experience toxic shock syndrome; seek emergency care for sudden fever, rash, or muscle aches.

NuvaRing Boxed Warning

Smoking and Serious Cardiovascular Events:

  • NuvaRing's boxed warning explains that the combined hormonal contraceptive may increase the risk of serious cardiovascular side effects.
  • This risk is higher in women who smoke and are over 35 years of age.
  • Do not smoke if you are using NuvaRing to prevent pregnancy.
Who Should Not Use NuvaRing?

Who Should Not Use NuvaRing?

  • Have uncontrolled high blood pressure.
  • Have breast cancer or a type of cancer that is sensitive to female hormones.

NuvaRing Vs Other Birth Control Options: Effectiveness Compared

NuvaRing Vs Other Birth Control Options: Effectiveness Compared

If you are wondering, “Is vaginal ring birth control right for you?” or searching “Which birth control option is more effective?” the answer depends on how consistently each method is used. Here’s a CDC-verified effectiveness comparison table for NuvaRing and other common birth control options.

Birth Control MethodTypical Use Failure Rate (% per year)Perfect Use Failure Rate (% per year)
NuvaRing (Vaginal Ring)7% (approx. 9%)<1% (approx. 0.3%)
Combined Oral Contraceptives (the pill)0.07<1%
Progestin-Only Pill0.07<1%
Patch (Hormonal)0.07<1%
Injectable (Depo-Provera)0.04<1%
Implant (e.g., Nexplanon)0.0010.001
Hormonal IUD (e.g., LNG IUD)0.2–0.4%0.2–0.4%
Copper IUD (ParaGard)0.0080.006
Male Condom0.130.02
Female Condom0.210.05
Diaphragm0.170.06
Spermicide Alone0.210.18

  • According to the CDC official report on “Contraception and Birth Control Methods:”
    • NuvaRing, combined pills, and the patch all have similar effectiveness in real-world use (7–9% typical failure) because they require ongoing user involvement.
    • Long-acting reversible contraceptives (LARCs) like implants and IUDs have the lowest failure rates because they do not depend on frequent user action.
