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.

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:
However, like any contraceptive method, it does come with specific side effects:
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:
The effectiveness of vaginal ring contraceptives, including NuvaRing, depends largely on using the ring on schedule.
If you are inserting the NuvaRing birth control ring for the first time, follow these steps:
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.
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.
By working through these steps, NuvaRing provides highly effective contraception when used as directed.
Here are some possible side effects that users may notice while using the NuvaRing birth control ring, if not used correctly.
| Side Effect | How Common | Notes |
|---|---|---|
| Vaginal irritation or discomfort | Common | May improve over time. |
| Headache or migraine | Common | See your provider if severe. |
| Nausea | Common | Usually mild. |
| Breast tenderness or pain | Common | Often improves after a few cycles. |
| Vaginal discharge | Common | See your provider if severe. |
| Mood changes (including depression) | Less common | Discuss persistent symptoms with your medical provider. |
| Weight changes | Less common | Varies by individual. |
| Serious blood clots or stroke | Rare | More likely in high‑risk individuals — see Warnings. |
| Hypertension | Less common | Discuss symptoms with your doctor |
| Hepatic tumors | Less common | Discuss symptoms with your doctor |
