Birth Control & Family Planning
Birth Control Ring vs. Patch: How They Work and Which to Choose
The ring and the patch both release estrogen and progestin, the same two hormones in combined birth control pills, and both are about 93% effective with typical use. The difference is the routine: you change the patch once a week and the ring once a month (or reuse one ring for a year with Annovera). So the real question is whether you'd rather have something on your skin or something in your vagina.
The quick comparison
| Ring | Patch | Combined pill | |
|---|---|---|---|
| How often | Monthly or yearly | Weekly | Daily |
| Typical-use effectiveness | About 93% | About 93% | About 93% |
| Visible | No | Sometimes | No |
| Common side effects | Discharge, irritation, spotting | Skin irritation, breast tenderness | Nausea, spotting |
| Estrogen safety rules apply | Yes | Yes | Yes |
That 93% means about 7 in 100 people get pregnant in a year of real-life use, mostly because of late changes or gaps. Used perfectly, both are over 99% effective.
How they work
Both deliver hormones that:
- Stop ovulation
- Thicken cervical mucus
Because they contain estrogen, they follow the same safety rules as combined pills. People with migraine with aura, a history of blood clots, high blood pressure that isn't controlled, certain heart or liver conditions, or who smoke and are 35 or older usually shouldn't use them.
Choose the ring if...
- You don't want anything visible
- You'd like to deal with birth control once a month (or once a year)
- You're comfortable using tampons, since insertion feels similar
What using the ring is really like
The ring is soft, flexible and about 2 inches across. You squeeze it between your fingers and push it into your vagina as far as is comfortable. Exact placement doesn't matter; your muscles hold it. Most people can't feel it once it's in, and the most common question ("Will my partner feel it?") usually gets a no. If it bothers either of you, the ring can come out for sex for a short time. Check your label for the limit.
The first try is often the awkward one. Many people find it easiest standing with one leg up on the edge of the tub, or squatting.
| Monthly ring (NuvaRing and generics) | Yearly reusable ring (Annovera) | |
|---|---|---|
| Hormones | Etonogestrel + ethinyl estradiol | Segesterone acetate + ethinyl estradiol |
| Typical schedule | 3 weeks in, 1 week out, then a new ring | 3 weeks in, 1 week out, then reinsert the same ring |
| How long one ring lasts | 1 cycle | Up to 13 cycles (about 1 year) |
| Storage | Per label | Kept in its case during the week out |
Downsides people mention: more vaginal discharge, some irritation, and the ring occasionally slipping out during sex, when removing a tampon, or during a bowel movement. Labels explain how long it can be out before you need backup, so read that part before it happens.
Choose the patch if...
- You don't want anything inside your vagina
- A weekly routine is easier to remember than a daily one
- You like being able to glance down and confirm it's there
What using the patch is really like
The patch is a thin, square sticker about the size of a matchbook. You put it on clean, dry skin on your belly, buttocks, upper back or upper arm (your brand's label lists the allowed spots). Skip lotion on that area first, or it won't stick well.
You wear a new patch each week for 3 weeks, then go patch-free for 1 week, when you usually get a period. Pick a "patch day" you'll remember, like Sunday night, and set a phone reminder.
- Xulane and Zafemy: norelgestromin + ethinyl estradiol
- Twirla: levonorgestrel + ethinyl estradiol
The patch is designed to stay on in the shower, at the gym and in the pool. Check it daily. If it loosens or falls off, your label tells you exactly what to do. A common annoyance is a sticky gray outline on the skin after removal; moving the patch to a new spot each week helps with irritation.
Downsides people mention: skin irritation, the patch being visible depending on where you put it, and edges lifting. Two more to know about:
- Some patches expose you to more estrogen overall than many pills. The FDA labels for Xulane and Zafemy carry a warning about this and about blood clot risk.
- Labels say patches may be less effective in people with higher body weight. Twirla isn't intended for people with a BMI of 30 or higher. If that applies to you, ask whether the ring or another method fits better.
Side effects you might notice with either
In the first few months, many people have:
- Spotting or breakthrough bleeding
- Breast tenderness
- Nausea
- Headaches
- Mood changes
These often settle within 3 months, so give it a fair trial before switching unless something is really bothering you. Serious risks are rare but include blood clots, stroke and heart attack. Get emergency care for severe chest pain, shortness of breath, a sudden severe headache, vision changes, or painful swelling in one leg.
Can you skip your period?
Yes, for most people. Many use the ring or patch continuously, skipping the hormone-free week, to have fewer or no periods. Spotting is common at first and usually improves. Ask your clinician how to do this with your specific product, and see our guide to birth control and your period.
Starting either one
You can start on any day you're reasonably sure you're not pregnant. Per CDC guidance, if you start within the first 5 days after your period begins, you don't need backup. Any other time, use condoms or skip sex for the first 7 days.
Switching from the pill? Ask your clinician or pharmacist how to switch without a gap.
Medicines that can interfere
Like the pill, the ring and patch can be affected by some seizure medicines, rifampin, some HIV medicines and St. John's wort. Common antibiotics generally don't reduce effectiveness, which is something a lot of people worry about. Tell your pharmacist everything you take.
Tampons and menstrual cups with the ring
Tampons are generally fine. Pull the tampon out slowly so the ring doesn't come with it. Menstrual cups and discs may dislodge a ring, so check the label or ask your clinician.
Getting the ring or patch in New York
You can get a prescription from an OB/GYN, nurse practitioner or midwife, including by telehealth. Under New York's 2024 statewide standing order, participating pharmacists can also dispense the ring or patch after you fill out a self-screening form. That can be handy if you're between doctors. See our guide to getting birth control from a New York pharmacist.
Ask your pharmacy about cost before you pick it up. Generic rings are often cheaper than brand-name ones, and coverage varies by plan.
When to see a doctor
See a clinician before starting if you have migraines, high blood pressure, diabetes, a history of blood clots, liver disease, or you smoke and are 35 or older. Call your provider if you have:
- Spotting that lasts beyond 3 months
- A missed period and possible pregnancy
- Vaginal pain, sores or unusual discharge with the ring
- A severe skin reaction to the patch
Your next step
OB/GYNs and women's health nurse practitioners across New York can help you compare the ring and patch with other options. Search the directory to find one near you, and bring your list of medicines and any history of migraines or clots.
Frequently asked questions
Is the ring or the patch more effective?
They are about equally effective. With typical use, about 7 in 100 users of either method get pregnant in a year, the same as the pill. Used perfectly, both are over 99% effective.
Can my partner feel the birth control ring?
Most partners do not notice it, and most users cannot feel it once it is in place. The ring can also be removed for sex for a short time; check the label for the limit.
Does the patch work if I have a higher body weight?
Patch labels say they may be less effective in people with higher body weight or BMI, and one brand, Twirla, is not for people with a BMI of 30 or higher. Ask your clinician if another method is a better fit.
Can I skip my period with the ring or patch?
Many clinicians support using the ring or patch continuously, skipping the hormone-free week, to reduce or skip periods. Ask your clinician how to do this with your specific product.
