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.

Do not share this medication with others.

Regular complete physical exams which include lab and/or medical tests (such as blood pressure, breast exam, pelvic exam, Pap smear) should be done while you are using this medication. Follow your doctor's instructions for examining your breasts, and report any lumps right away. Keep all medical and lab appointments. Consult your doctor for more details.

If the patch comes off or if you forget to remove it at the proper time, refer to the product package information or How to Use section for instructions. You may need to use backup birth control (such as condoms, spermicide) to prevent pregnancy. Ask your doctor or pharmacist if you have any questions.

If you have trouble remembering to change your patch, or if the patch often comes off, contact your doctor to discuss switching to another form of birth control.

Store in the protective pouches at room temperature away from light and moisture. Keep all medications away from children and pets.

Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed. (See also How to Use section.)

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.

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.

This medication patch may be harmful if chewed or swallowed. If someone has overdosed, remove the patch if possible. For serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call 1-800-222-1222. Canada residents can call 1-844-764-7669.

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.
