The norelgestromin patch (Xulane) is a prescription skin patch that prevents pregnancy. Each patch delivers two hormones through the skin: norelgestromin, a progestin, and ethinyl estradiol, an estrogen. You wear one patch a week for three weeks, then have a patch-free week. It is FDA-approved combined hormonal contraception, not a supplement or an over-the-counter product.
This page explains, in everyday language, what the official labeling says formally: who the patch is meant for, what it feels like to use, which side effects are common, which warnings are serious, and what a month tends to cost when you pay for it yourself. It is a reference page, not a prescription and not a recommendation.
What the norelgestromin patch (Xulane) is
Xulane is a brand of the norelgestromin and ethinyl estradiol transdermal system. Transdermal simply means the medicine crosses your skin instead of going through your stomach. The patch is thin, beige and roughly the size of a large postage stamp. It sticks in place through showers, swimming and exercise, and it keeps releasing hormone the whole time it is on.
The drug class is a combination of progestin and estrogen, the same pairing used in most combined birth control pills. Because the hormone comes through skin rather than the gut, you do not have to remember a daily dose. That is the main practical appeal for many people who switch from pills.
The labeling is specific about who it is for. According to the product’s prescribing information published on DailyMed, this patch is indicated to prevent pregnancy in women with a body mass index under 30 kg/m2 for whom a combined hormonal contraceptive is appropriate. The label also flags that it may work less well in people who weigh 198 pounds (90 kg) or more, and it is contraindicated at a BMI of 30 or above. That is unusual: most contraceptives do not carry a body-size cutoff, and this one does.
It prevents pregnancy only. It does not protect against HIV or other sexually transmitted infections. Condoms remain the barrier method for that, and clinicians often suggest using both.
How the hormones in the patch prevent pregnancy
Combined hormonal contraception works in three overlapping ways. First, and most importantly, the steady hormone level tells the brain to stop the monthly signal that triggers ovulation. No egg is released, so there is nothing to fertilise. Second, the progestin thickens cervical mucus, which makes sperm movement harder. Third, the lining of the uterus becomes thinner and less receptive.
The delivery route is what makes a patch different from a pill. Swallowed hormone passes through the liver before it reaches the bloodstream, so blood levels rise and fall each day. A patch feeds hormone in continuously and skips that first pass. Labeling for this product notes that overall estrogen exposure with the patch runs higher than with a 35 microgram oral tablet, which matters for the safety discussion further down this page.
Effectiveness is best understood as two numbers. With perfect use, combined hormonal methods fail in well under one percent of users per year. With typical use, meaning real people with real weeks, the failure rate is higher, in the range of several pregnancies per hundred users a year. The CDC’s contraception effectiveness summary is a useful reference point for comparing methods on the same basis. Patches, pills and rings all land in the same broad tier, which is why the choice usually comes down to what you will actually keep using.
Wearing it: placement, the weekly rhythm and bleeding
The schedule in the labeling is one patch per week for three consecutive weeks, applied on the same day each week, followed by a patch-free fourth week. Then the cycle repeats. Your clinician tells you which day to start and whether you need backup contraception for the first several days. Do not build your own schedule from a web page.
Placement matters more than people expect. Suitable sites are clean, dry, intact skin on the lower abdomen, the buttock, the upper outer arm or the upper torso, avoiding the breasts. Skip lotion, oil, powder or makeup on that patch of skin, since anything greasy loosens the adhesive. Press the patch down firmly with your palm for about ten seconds and run a finger around the edge. Planned Parenthood publishes step-by-step patch placement guidance if you want a visual walkthrough.
Rotating sites each week helps, because the adhesive can leave a ring of irritation. If a patch lifts at the edge, partly detaches or falls off, that is not a minor cosmetic issue: hormone delivery drops and pregnancy risk rises. The labeling gives specific instructions based on how long the patch was off, so call your prescriber or pharmacist rather than guessing.
Bleeding usually happens during the patch-free week, and it is withdrawal bleeding rather than a true period. Many users find it lighter and more predictable than their natural cycle. Spotting between patches is common in the first few months and often settles. Some people ask about skipping the patch-free week to skip bleeding entirely. That is a real clinical conversation with tradeoffs, and it is one to have with a prescriber rather than improvise.
Side effects people actually report
Most side effects of the norelgestromin patch (Xulane) are the ordinary nuisances of combined hormonal contraception, plus one that is unique to patches: the sticker itself.
- Application site reactions. Redness, itching, a residue ring or mild irritation where the patch sits. Rotating placement helps.
- Nausea and stomach upset. Common early, often fading after a cycle or two.
- Breast tenderness or swelling. Frequently reported in the first months.
- Headache. Usually mild, but new or worsening headaches deserve a mention to your clinician.
- Irregular bleeding or spotting. Very common at first; persistent bleeding is worth reviewing.
- Mood changes. Some users report low mood or irritability. Labeling for combined hormonal contraceptives notes depression as a possible effect, so raise it if it appears.
- Patch detachment. A practical side effect with a real consequence, not just an annoyance.
Weight gain is the question searchers ask most. The label lists weight change among reported effects, but the broader evidence for combined hormonal contraception does not show meaningful average weight gain. A Cochrane review of combination contraceptives and weight found no large effect across studies. Fluid retention and breast fullness in early cycles can feel like weight gain, and individual experience still varies. A scale over three months tells you more than the first two weeks do.
Serious effects are far less common but need naming. Signs of a blood clot, liver problems or a stroke are covered in the urgent-symptoms section below, because knowing them is more useful than knowing a frequency table. Patient-facing summaries such as the Cleveland Clinic overview of this contraceptive patch list the same categories in similar plain terms.
The boxed warning, BMI limits and clot risk
This product carries a boxed warning, which is the strongest warning US labeling uses. It covers two things.
The first is smoking. Cigarette smoking raises the risk of serious cardiovascular events with any hormonal contraceptive, and that risk climbs with age and with the number of cigarettes. Combined hormonal contraceptives, including this patch, are contraindicated in women over 35 who smoke. That is a hard line in the labeling, not a suggestion.
The second is body mass index. Use is contraindicated at a BMI of 30 kg/m2 or higher, and the label notes reduced effectiveness at 198 pounds or more. If you are unsure where you fall, this calculator gives you the number your clinician will use.
BMI calculator
Most weight-loss programmes screen on BMI before they will prescribe. This is the number they will use.
A screening number, not a diagnosis. It does not distinguish muscle from fat, and it reads high for muscular builds.
The rest of the warnings section deals with vascular risk. All estrogen-containing contraception raises the chance of venous thromboembolism, meaning a clot in a leg vein or lung. The labeling instructs that the patch be stopped if a thrombotic event occurs, stopped at least four weeks before major surgery and not resumed until two weeks after, and started no earlier than four weeks after delivery in people who are not breastfeeding. Because a patch produces higher overall estrogen exposure than a low-dose pill, clot risk with patches versus pills has been studied and debated; treat it as a real conversation to have if you already carry clot risk factors.
Other label-flagged issues follow the same pattern of stop, avoid or monitor. Discontinue if jaundice, a yellowing of skin or eyes, appears. Do not use with uncontrolled high blood pressure or hypertension with vascular disease. Blood sugar and lipids can shift, so people with diabetes or high cholesterol may need monitoring. Gallbladder disease, migraine with aura, a history of breast cancer, certain liver tumors and current pregnancy all belong in the pre-prescription screening conversation. The American College of Obstetricians and Gynecologists explains combined hormonal methods for patients in similar terms.
Medicines and supplements that can interfere
Drug interactions with combined hormonal contraception run in two directions: something weakens the contraceptive, or the contraceptive changes another drug.
The main mechanism is liver enzyme induction. Certain medicines speed up how fast your body clears estrogen and progestin, which can lower contraceptive effectiveness and cause breakthrough bleeding. Categories to disclose include rifampin and related antibiotics, several seizure medicines such as carbamazepine, phenytoin, phenobarbital and topiramate, some HIV and hepatitis C antivirals, and the herbal supplement St John’s wort. Certain hepatitis C combination regimens containing ritonavir are contraindicated with ethinyl estradiol because of liver enzyme elevations.
Going the other way, combined hormonal contraceptives can lower lamotrigine levels, which matters if you take it for epilepsy or bipolar disorder. Thyroid hormone and corticosteroid requirements can also change. None of that means you cannot use contraception; it means the choice and the monitoring plan should be deliberate.
Two practical habits protect you. Keep one current list of everything you take, including supplements, and hand the whole list over at every visit. Then ask directly whether anything on it affects patch effectiveness and whether you need backup contraception during and after a short course of a new drug. Mayo Clinic maintains a detailed interaction list for this transdermal combination if you want to check a specific name before your appointment.
Generic patches, brand names and the levonorgestrel alternative
Searchers often ask whether Xulane and the norelgestromin patch are two different things. They are not. Xulane is a brand name for the norelgestromin and ethinyl estradiol transdermal system, sold in a single labeled strength. Generic and additional branded versions of the same combination exist under other names. The original US brand patch, Ortho Evra, is no longer marketed, which is why the generic-style naming now dominates pharmacy shelves.
The genuinely different product is Twirla, a weekly patch that pairs ethinyl estradiol with levonorgestrel instead of norelgestromin. It is a separate approved product with its own labeling, its own BMI-related restrictions and its own effectiveness data, so treat it as a distinct option rather than a substitute you can swap yourself.
| Question | Norelgestromin patch | Levonorgestrel patch (Twirla) | Combined pill |
|---|---|---|---|
| Progestin used | Norelgestromin | Levonorgestrel | Varies by product |
| How often you act | Weekly | Weekly | Daily |
| Route | Through the skin | Through the skin | Swallowed |
| Body-size limits in labeling | Yes, BMI-based | Yes, check its own label | Generally none stated |
| Visible on the body | Yes | Yes | No |
Patch versus pill usually comes down to habit, not chemistry. A weekly action suits people who forget daily doses; a pill suits people who dislike adhesive marks or skin irritation.

What a month costs when you pay cash
Cost questions about this patch split into two routes that should never be mixed together: cash pay, meaning what a self-pay patient hands over, and insurance, where the only number a telehealth program controls is its own plan or membership fee. Copays and deductibles sit on top of that and vary by plan and state.
On the cash side, a one-month supply means three patches, since the fourth week is patch-free. For the programs we track that prescribe this method, the lowest self-pay monthly figure is and the median sits at . Advertised prices move often, so treat any figure as a snapshot rather than a fixture.
Four things move the number. Brand versus generic version of the same patch, because generics are usually the cheaper line. The pharmacy that fills it, since cash prices for identical products differ between retailers. Whether a telehealth program bundles the prescription visit into the monthly price or bills it separately. And whether an introductory price steps up at renewal, which is the single most common surprise in subscription contraception.
Because contraception is a long-running cost rather than a one-off, the annual view is the honest one. This calculator turns a monthly figure into what you would actually spend over a year.
What a year actually costs
Programmes quote a monthly headline. Add the medication, the labs and the renewal price and the real number is usually different.
Advertised prices change often and intro pricing rarely lasts. Ask what the renewal rate is before you commit to a plan.
On the insurance route, federal rules require most plans to cover contraceptive services without cost sharing, but which specific patch appears on your plan’s formulary varies, and exclusions and step requirements exist. Never assume coverage from a general rule; call the number on your card and ask about this exact product. KFF publishes ongoing policy analysis of contraceptive coverage that explains why plan-level answers differ so much.

How online birth control programs handle the patch
Telehealth prescribing for contraception is mature and largely asynchronous. You complete a health history, blood pressure and BMI questions, and a licensed clinician reviews it. Some programs use a short video or phone visit instead. State telemedicine and prescribing rules decide what is possible where you live, so availability is not uniform across the country.
What varies between programs is worth comparing line by line before you sign up:
- Screening depth. Blood pressure and smoking history are not optional extras for estrogen-containing contraception. A program that skips them is cutting a corner the labeling does not allow.
- Whether the patch is on the menu. Many contraception programs lead with pills and stock fewer patch options.
- What the monthly price includes. Medication, visit, refills and messaging may be bundled or billed apart.
- Refill and shipping cadence. Contraception is unforgiving of gaps, so reliability beats speed.
- Follow-up access. Breakthrough bleeding and side effects usually need a real reply, not a help article.
- Insurance handling. Some programs bill plans; others are cash only.

Questions worth asking, and when to get help fast
Bring a short list to your appointment. Useful questions include: given my blood pressure, BMI, migraine history and family clot history, is an estrogen-containing method appropriate for me at all? What should I do if a patch falls off or I forget to change it on time? Which of my current medicines could make this less effective? What bleeding pattern should I expect in the first three months, and at what point does it stop being normal? Which non-estrogen options, including progestin-only methods, an IUD or an implant, would you consider if this one does not suit me?
Questions to Bring to Your Appointment
- Is an estrogen-containing method appropriate given my blood pressure, BMI, migraine and clot history?
- What should I do if a patch falls off or I forget to change it on time?
- Which of my current medicines or supplements could reduce effectiveness?
- What bleeding pattern is normal in the first three months-and when is it not?
- Should I use backup contraception when starting or after a short course of a new drug?
- What non-estrogen alternatives would you consider if this patch doesn't suit me?
Some symptoms are not wait-and-see. Get urgent medical care for sudden shortness of breath, chest pain, coughing up blood, pain or swelling in one leg, a sudden severe headache unlike your usual pattern, sudden vision loss or changes, weakness or numbness on one side of the body, trouble speaking, severe abdominal pain, or yellowing of the skin or eyes. Tell the clinician you are using an estrogen-containing contraceptive patch, because it changes how they read those symptoms. If you might be pregnant, stop and check before continuing.
