Key takeaways
- The patch delivers estrogen plus a progestogen through the skin and is changed weekly: 3 patches over 3 weeks, then one patch-free week when a withdrawal bleed occurs.
- Effectiveness is similar to the combined pill, about 9 pregnancies per 100 women a year with typical use and 0.3 with perfect use, but weekly action is easier to get right than a daily pill.
- It carries the same estrogen-related cautions as the pill, with a slightly higher blood-clot (VTE) risk and possibly reduced effectiveness in women weighing over 90 kg.
- In India the patch is very hard to buy: it is not routinely stocked, not in the national family-planning programme, and usually only reachable via costly import.
- For most Indian women, the pill, vaginal ring, injection, implant, IUD, or the weekly non-hormonal Saheli pill offer similar benefits with far better access.
What the Contraceptive Patch Is and How It Works
The contraceptive patch is a thin, beige adhesive square (roughly 4 cm across) that sticks to your skin for a week at a time. Embedded in its adhesive layer are two hormones, ethinyl estradiol (a synthetic estrogen) and norelgestromin (a progestogen), which release steadily and absorb through the skin into your bloodstream over the 7-day wear.
The daily amount delivered is roughly 20 micrograms of ethinyl estradiol and 150 micrograms of norelgestromin, in the same range as a low-dose combined oral contraceptive pill. Because it contains estrogen, it counts as a combined hormonal method, not a progestogen-only one.
The way it prevents pregnancy is the same as the combined pill. The steady hormone level switches off the brain's ovulation signal so no egg is released. It also thickens cervical mucus to block sperm and thins the womb lining. The advantage is purely practical: effectiveness depends on a weekly action rather than remembering a tablet every single day.
A standard cycle runs over four weeks. You wear patch one for 7 days, swap it for patch two, then patch three, so three patches cover three weeks. You then take a patch-free week, during which a withdrawal bleed usually comes, before starting the next cycle on the same weekday. Some women skip the patch-free week and wear patches continuously to avoid the bleed, which is generally safe.
How to Apply, Wear, and Replace the Patch
Application is simple, but a few details matter for the patch to stick and absorb reliably. The recommended sites are the buttock (the most popular, as it stays hidden and rubs less), the upper outer arm, the lower abdomen, or the upper back or chest. Never put it on the breast. The skin should be clean, dry, and free of cuts, rashes, or recent sunburn, and away from anywhere a waistband or bra strap will rub it loose.
To apply it: clean the area with plain water and dry it well. Do not use lotion, oil, powder, or makeup on the spot first, as these stop the adhesive gripping. Peel off half the plastic backing, press the sticky side firmly onto your skin, then remove the rest of the backing and press the whole patch down for about 30 seconds, smoothing every edge. Check it once or twice the first day, then daily, to make sure no edges are lifting.
You can shower, bathe, swim, and exercise with the patch on; the adhesive is built to survive water and sweat. If an edge lifts, press it back. If a patch falls off and has been off for less than 24 hours, reapply it (or a fresh one) and keep your usual schedule. If it has been off for 24 hours or more, put on a new patch, treat that day as the start of a new cycle, and use backup contraception such as condoms for 7 days.
Change the patch on the same weekday each week, the day people often call your "patch change day", and move it to a slightly different spot each time to reduce skin irritation. After three patches over three weeks, take your patch-free week, then start again on your usual change day.
Effectiveness: Perfect Use Versus Typical Use
The patch is about as effective as the combined pill. With perfect use, roughly 0.3 in 100 women get pregnant in a year. With typical, real-life use, the figure is around 9 in 100, the same ballpark as the pill. The gap between perfect and typical use tends to be a little narrower for the patch, simply because changing something once a week is easier to remember than a daily tablet.
One important caveat is body weight. The original Evra labelling warns that the patch may be less effective in women who weigh more than 90 kg (about 198 lb), the idea being that the hormones are spread through a larger body and may not reach a fully protective level. The evidence is not fully consistent, but if you weigh over 90 kg it is worth discussing a different method, such as an IUD, implant, injection, or a pill that can be tailored to your needs.
Compared with other methods, the patch is less reliable in typical use than the IUD, implant, and injection, which work continuously without any user action and have failure rates under 1 in 100. It is more reliable than How Effective Are Condoms? Failure Rates, Correct Use & STI Protection used alone, and broadly equal to the pill and the vaginal ring. It suits women who want combined hormonal contraception, find a daily pill hard to keep up, have no reason to avoid estrogen, weigh under 90 kg, and can actually get hold of the patch.
Side Effects and Tolerability
The patch's side effects largely mirror the combined pill, with a couple of differences from the skin route. Hormone-related effects can include breast tenderness, headaches, mood changes (including low mood in a minority), small weight changes, occasional acne or skin changes, and reduced sex drive in some women. Nausea tends to be milder than with the pill because the hormones do not pass through the stomach, which is a genuine plus for women who felt sick on tablets.
The patch's own specific issue is skin reaction at the application site, with redness, itching, or mild irritation in roughly 10 to 20 percent of users. This is usually mild and settles, and rotating the site each week helps. A severe or blistering reaction is a reason to stop and switch methods. Some women also dislike the patch being visible, which is a preference, not a safety, concern.
The one safety point that deserves attention is blood clots. Like all estrogen-containing methods, the patch raises the risk of venous thromboembolism (VTE, clots in the legs or lungs), and some studies suggest the patch may carry a slightly higher risk than the pill, possibly because the skin route delivers a bit more estrogen overall. The absolute risk is still low, in the region of 6 to 12 cases per 10,000 women a year versus 3 to 9 with the pill, and both are well below the clot risk of pregnancy itself (around 30 per 10,000). Still, if you have any clotting risk factors, a different method may be wiser. You can read more in our guide to blood clots and DVT in women.
Bleeding Patterns and Cycle Control
Used in the usual 3-weeks-on, 1-week-off pattern, the patch gives a bleed much like the pill or the ring. The withdrawal bleed usually starts 2 to 3 days into the patch-free week and lasts 3 to 7 days. It is often lighter and more predictable than a natural period, because the steady hormone level keeps the womb lining thin, a benefit many women value.
Breakthrough bleeding (spotting while you are still wearing patches) happens in about 5 to 15 percent of users, mostly in the first three months, and usually settles with continued use. If it carries on well beyond that, the formulation may not suit you, and switching to a different combined method or another approach entirely is reasonable.
Some women use the patch continuously, applying a fresh patch instead of taking the patch-free week, to skip the bleed altogether. This is generally safe and is sometimes used for heavy or painful periods, endometriosis, or simply for convenience around travel and events. It can cause more spotting in the early months. If you want to try this, plan it with your gynaecologist, for example whether to allow a bleed every three months and how to manage any spotting. The patch's flexibility between cyclic and continuous use is one feature some women find genuinely useful.
Indian Availability and the Realistic Access Picture
This is where the patch falls down for most women in India. As of 2025-2026, Evra is not routinely stocked in Indian pharmacies; major chains do not generally carry it, and even ordering through their networks may not bring reliable supply. It is not part of the national family-planning programme, is seldom found even in big hospital pharmacies, and no Indian manufacturer makes a generic version, so domestic options simply do not exist.
In practice, women who specifically want the patch reach it in a few constrained ways: through international online pharmacies that ship to India (with cost, authenticity, and regulatory uncertainty, often roughly 2,000 to 5,000 rupees per monthly set of three patches plus shipping); by buying it while travelling to countries where it is widely sold; or via special import arranged by some large metro hospital pharmacies for individual patients, which can take 3 to 6 weeks and cost around 3,000 to 7,000 rupees a cycle. Many Indian gynaecologists also have limited hands-on experience with the patch because it is so rarely used here.
For most women, the sensible move is a better-stocked alternative that does a similar job. If the appeal is avoiding a daily tablet, options include the vaginal ring (also specialty-only but somewhat easier than the patch), the contraceptive injection (DMPA every three months, free at government clinics or 400 to 1,500 rupees privately), the contraceptive implant (three years), or a copper or hormonal IUD. And for women who specifically want a weekly, not daily, pill, India's home-grown non-hormonal Saheli (Centchroman) is taken once a week and costs only 50 to 150 rupees a month, covered alongside other choices in our non-hormonal birth control guide.
Who Is and Isn't Suited to the Patch
The patch may suit you if you want combined hormonal contraception, with its added benefits for cycle regularity, The Pill for Acne: Which Birth Control Clears Skin, and Who It Suits, and lighter periods, but find a daily pill hard to keep up; you have no reason to avoid estrogen; you weigh under 90 kg; you are comfortable with a visible skin patch; and you can reliably source it.
The cautions are the same as for the combined pill, with a slightly lower threshold to avoid it if you have clotting risk. You should not use the patch if you smoke and are over 35; have a history of blood clots, a known clotting disorder, stroke, or heart disease; have current breast cancer; have active liver disease; have uncontrolled high blood pressure; have migraine with aura; have diabetes with vascular complications; are pregnant; have unexplained vaginal bleeding; or are within 21 days of giving birth (longer if breastfeeding). Relative cautions, where it may still be possible with care, include well-controlled hypertension or diabetes, migraine without aura, and certain interacting medications.
Patch vs Pills vs Ring: The Combined Hormonal Choice
The three combined hormonal routes deliver the same kind of hormones; the difference is how often you act and how easy each is to get in India.
Combined pills (daily): one tablet a day. Best access by far, available at any pharmacy for roughly 200 to 500 rupees a month, with free options at government clinics and the widest range of formulations to match your body. The downside is the daily discipline, and missed pills cut effectiveness. They can also be used to regulate or delay periods when needed.
Vaginal ring (monthly): one soft ring worn for three weeks, then a ring-free week. Very convenient and low-dose, but availability in India is limited to specialty channels (around 1,500 to 5,000 rupees a ring), and it requires comfort with inserting and removing a vaginal device.
Patch (weekly): a fresh patch each week for three weeks. Weekly action is easier than daily for some, and you can see it is in place. But access in India is the worst of the three (largely import-only, 2,000 to 7,000 rupees a cycle), it is visible, it can irritate the skin, it may be weaker over 90 kg, and it carries a slightly higher clot risk than the pill.
For Indian women, the practical ranking is pills first, ring second, patch third. And if the real goal is simply non-daily contraception with good access, methods outside the combined family, the injection, implant, IUD, or weekly Saheli, are usually more workable than the patch.
Drug Interactions and Special Cautions
Because the patch puts hormones into your bloodstream, its drug interactions are the same as the combined pill. The medicines that can reduce its effectiveness include enzyme-inducing anti-epileptics (carbamazepine, phenytoin, phenobarbital, topiramate, oxcarbazepine, primidone), the tuberculosis drugs rifampicin and rifabutin, some HIV medicines (such as efavirenz, nevirapine, and certain protease-inhibitor combinations, where your HIV specialist should advise), and the herbal supplement St John's Wort. If you take any of these long term, a different method is usually recommended.
Reassuringly, ordinary antibiotics, amoxicillin, azithromycin, doxycycline, and the like, do not reduce the patch's effectiveness. The old advice to use backup during every antibiotic course no longer applies, so a short course for a chest, urine, or skin infection does not need extra precautions.
Some situations call for a check-in with your doctor: major surgery with prolonged bed rest (the patch is usually stopped 4 to 6 weeks beforehand to lower clot risk and restarted after you are mobile again); starting any of the interacting medicines above; new severe headaches or migraine with aura (stop the patch and switch to a progestogen-only or non-hormonal method); a blood-pressure rise above 140/90; or a new breast lump that needs assessment. Plan a yearly review covering blood pressure, your application sites, any new medicines or symptoms, and whether the method still fits your life.
Starting, Switching, and Stopping the Patch
Starting: the simplest approach is to apply your first patch on day 1 of your period, which protects you straight away with no backup needed. You can also "quick start" on any day, once pregnancy is reasonably excluded, using condoms for the first 7 days. Pick a patch change day that suits your week, as it sets your weekly rhythm.
Switching: from the combined pill, apply the first patch within the pill-free week, with no backup needed. From a progestogen-only pill, apply it any day, stop the pill, and use backup for 7 days. From the injection or implant, apply it when the next dose is due or at removal, with 7 days of backup. From an IUD, apply it on the day of removal, again with 7 days of backup.
Stopping: simply don't apply the next patch. Effectiveness fades within days as the hormones clear. Most women's natural cycle returns within 4 to 6 weeks, and ovulation can resume in that first cycle, so pregnancy is possible right away (see how fertility returns after stopping hormonal birth control). If you are planning to conceive, ideally start folic acid at 400 to 800 mcg daily one to three months before stopping.
Contraceptive Patch Myths, Corrected
Myth: The patch is like a nicotine patch and goes anywhere
- Only partly true. It does work like other transdermal patches, but it has specific recommended sites: the buttock, upper outer arm, lower abdomen, or upper back or chest. The breast is off-limits, and the sites are chosen for reliable absorption and adhesion.
- Avoid broken skin, rashes, recent sunburn, and spots where clothing or straps rub. Apply to clean, dry, product-free skin, and rotate the site weekly to spare your skin. Following these rules keeps both stickiness and hormone absorption dependable.
Myth: I can shower, swim, and exercise and it will stay on
- Mostly true. The adhesive is designed for real life, and most patches stay put through daily showers, swimming, and exercise for the full week. Drying your skin fully before applying, avoiding harsh scrubbing of the area, and keeping lotions and oils off it all help.
- If an edge lifts, press it back. If it falls off for under 24 hours, reapply and keep your schedule. If it has been off 24 hours or more, start a new cycle from that day and use backup for 7 days. Water sports and exercise are generally fine with the patch.
Myth: The patch causes more weight gain than the pill
- Largely false. Studies comparing the patch and the combined pill have not consistently shown more weight gain with the patch. Both can be linked to modest changes (often a kilo or two, up or down) that vary hugely between individuals; most women see little change.
- Part of the perception may be that you see the patch every day, so any change feels connected to it, whereas a pill is taken privately. Weight is rarely the deciding factor between these two routes; access, cost, dosing convenience, and other side effects usually matter more.
Myth: The patch is far more dangerous than the pill
- Partly true, with context. Some large studies estimate the patch carries about 1.5 to 2 times the blood-clot (VTE) risk of the combined pill, likely because the skin route delivers slightly more total estrogen. Regulators do flag this on the label.
- But the absolute risk stays low: roughly 6 to 12 VTE cases per 10,000 women a year with the patch versus 3 to 9 with the pill, both far below pregnancy (about 30) and the weeks after birth (about 80 to 100). For most women without clotting risk factors, the difference is small. If you do have risk factors, smoking, age over 35, a clotting history, or recent surgery, pills or non-estrogen methods are the safer pick. Talk through your own risk with your gynaecologist.
Frequently asked questions
Can I buy the contraceptive patch in India?
Not easily. Evra is not routinely stocked in Indian pharmacies and is not part of the national family-planning programme. Most women who get it rely on international online pharmacies, buying it while travelling, or special hospital import, which is slow and costs roughly 2,000 to 7,000 rupees a cycle. For most people, the pill, ring, injection, implant, IUD, or weekly Saheli are far more practical.
How effective is the patch compared with the pill?
About the same: roughly 0.3 pregnancies per 100 women a year with perfect use and around 9 with typical use. The patch's weekly schedule is a little easier to keep up than a daily pill, but it may be less effective in women who weigh over 90 kg.
Does the patch fall off in the shower or while swimming?
It is built to stay on through showering, bathing, swimming, and exercise, and most patches last the full 7 days. Check it regularly. If it falls off for under 24 hours, reapply and continue; if it is off for 24 hours or more, start a new cycle and use backup contraception for 7 days.
Is the patch safe if I have a higher risk of blood clots?
It carries the same estrogen-related clot risk as the pill, possibly slightly higher. If you smoke and are over 35, have a personal or family history of clots, have had recent surgery, or have other clotting risk factors, the patch is generally not recommended, and a non-estrogen method such as a progestogen-only pill, implant, injection, or copper IUD is safer. Discuss your individual risk with your doctor.
How soon can I get pregnant after stopping the patch?
Quickly. The hormones clear within days, your natural cycle usually returns within 4 to 6 weeks, and ovulation can happen in that first cycle, so pregnancy is possible right away. If you are planning to conceive, start folic acid one to three months before stopping.
