Smoking raises your risk of stroke, heart attack, blood clots, and high blood pressure from hormonal birth control (such as the pill, patch, ring). The risk of these serious problems is higher if you are obese and increases with age and with the number of cigarettes you smoke. Do not use this medication if you are obese, or if you smoke cigarettes/use tobacco and are over 35 years old.

The amount of estrogen you receive when using the patch is higher than the amount from most birth control pills. This may increase the risk for blood clots or other side effects from the patch compared to oral contraceptives. Talk to your doctor for more details.

This patch contains combination hormone medication and is used to prevent pregnancy. It contains 2 hormones: a progestin (norelgestromin) and an estrogen (ethinyl estradiol).

This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). To decrease your risk of infection, always use an effective barrier method (latex or polyurethane condom/dental dams) during all sexual activity. Consult your doctor or pharmacist for more details.

Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. The leaflet contains very important information on how to properly use and dispose of the patch. If you have any questions, ask your doctor or pharmacist.

Do not cut or damage the patch. Remove the patch from the foil pouch and apply as directed by the manufacturer to clean, dry skin on the upper outer arm, abdomen, buttock, or upper body where it will not be rubbed by tight clothing. Do not apply the patch to your breasts or on red/cut/irritated skin. Do not use lotions, creams, oils, powders, or make-up at the patch site, since it may not stick properly or may fall off.

If this is your first time using this medication, apply the patch on the first Sunday following the beginning of your menstrual period or on the first day of your period. If your period begins on a Sunday, begin on that day. For the first cycle of use only, use a backup form of non-hormonal birth control (such as condoms, spermicide) for the first 7 days to prevent pregnancy until the medication has enough time to work. If you start using the patch on the first day of your period, you do not need to use backup birth control the first week.

Change the patch once a week on the same day. Remove the used patch before placing a new one. Apply the patch to a different area with each change to avoid skin irritation. After wearing patches for 3 weeks in a row, do not wear a patch during week 4. You should have your period during this time. After not wearing a patch for a week, apply a new patch whether or not you have your period. If you do not get your period, consult your doctor. Do not go longer than 7 days without a patch, since this will increase your chance of pregnancy. To help you remember, mark your calendar to remind yourself when to change or leave off patches.

If the patch falls off, re-apply it or apply a new patch within 24 hours. If the patch is not replaced within 24 hours, or if you are not sure how long it has been off, start a new cycle by applying a new patch and use a backup form of non-hormonal birth control (such as condoms, spermicide) for the next 7 days to prevent pregnancy.

After removing each patch, fold it in half so it sticks to itself, and discard in the trash away from children and pets. Do not flush the patch down the toilet.

Ask your doctor or pharmacist about how to switch from other forms of hormonal birth control (such as birth control pills) to this product. If any information is unclear, consult the Patient Information Leaflet or your doctor or pharmacist.

Skin irritation at the application site, nausea, vomiting, headache, bloating, breast tenderness, swelling of the ankles/feet (fluid retention), or weight change may occur. Vaginal bleeding between periods (spotting) may occur, especially during the first few months of use. If any of these effects last or get worse, tell your doctor or pharmacist promptly. If you miss 2 periods in a row (or 1 period if the patch has not been used properly), talk to your doctor about a pregnancy test.

If you have diabetes, this medication may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. Your doctor may need to adjust your diabetes medication, exercise program, or diet.

Tell your doctor if you just had or will be having surgery or if you will be confined to a bed or chair for a long time (such as a long plane flight). These conditions increase your risk of getting blood clots, especially if you are using hormonal birth control. You may need to stop this medication for a time or take special precautions.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

This product may cause blotchy, dark areas on your face and skin (melasma). Sunlight may worsen this effect. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors.

If you are going to have an MRI test, tell testing personnel that you are using this patch. Some patches may contain metals that can cause serious burns during an MRI. Ask your doctor whether you will need to remove your patch before the test and apply a new patch afterward, and how to do so properly.

This medication must not be used during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor right away. If you have just given birth or had a pregnancy loss/abortion after the first 3 months, talk with your doctor about reliable forms of birth control, and find out when it is safe to start using birth control that contains a form of estrogen, such as this medication.

A small amount of this medication passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include:

• aromatase inhibitors (such as anastrozole, exemestane)
• fezolinetant
• ospemifene
• tamoxifen
• tizanidine
• tranexamic acid
• certain combination products used to treat chronic hepatitis C (ombitasvir/paritaprevir/ritonavir with or without dasabuvir)

Some drugs may cause hormonal birth control to work less well by decreasing the amount of birth control hormones in your body. This effect can result in pregnancy. Examples include griseofulvin, modafinil, rifamycins (such as rifampin, rifabutin), ritonavir, St. John's wort, drugs used to treat seizures (such as barbiturates, carbamazepine, felbamate, phenytoin, primidone, topiramate), HIV drugs (such as nelfinavir, nevirapine), among others.

Tell your doctor when you start any new drug, and discuss if you should use reliable backup birth control. Also tell your doctor if you have any new spotting or breakthrough bleeding, because these may be signs that your birth control is not working well.

This medication may interfere with certain lab tests (such as blood clotting factors, thyroid), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
