How does this medication work? What will it do for me?
This is a contraceptive (birth control) patch that is worn on the skin. The medication is continuously absorbed through the skin into the bloodstream. It is a combination contraceptive that contains 2 hormones (norelgestromin and ethinyl estradiol) to alter the female reproductive cycle. This medication prevents eggs from being released by the ovaries and changes the cervical mucus, making it harder for sperm to swim. This medication is used to prevent pregnancy.

How should I use this medication?
21-day pack: Take one tablet daily for 21 days, then take no pills for 7 days.
28-day pack: Take one tablet daily for 21 days, then one "reminder" pill daily for 7 days.
See the package insert for information on when to start and what to do if you forget to take a pill.
Talk with your doctor about the best time to start your pills. The first day of your menstrual period (bleeding) is known as "Day 1." Your doctor may have you start your pills on the first Sunday after your period starts or on Day 1 of your period. The pills should be taken approximately the same time every day.
It may be advisable to use a second method of birth control (e.g., latex condoms and spermicidal foam or gel) for the first 7 days of the first cycle of pill use.
Many women have spotting or light bleeding or may feel sick to their stomach during the first 3 months taking the pill. If you do feel sick, do not stop taking the pill. The problem will usually go away. If it does not go away, check with your doctor or clinic.
If you experience vomiting or diarrhea, or if you take certain medications (such as antibiotics), your pills may not work as well. If your doctor prescribes other medications, ask your doctor or pharmacist whether these medications could reduce the effectiveness of your birth control pills. Until you can check with your doctor or clinic to make certain that these things will not reduce the effectiveness of your birth control pills, use a backup method, such as latex condoms and spermicidal foam or gel.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is very important to take this medication exactly as prescribed by your doctor. If you miss pills at any time, the risk of becoming pregnant increases.
If you miss one pill, take it as soon as you remember, and take the next pill at the usual time. This means that you might take two pills in one day.
If you miss 2 pills in a row during the first 2 weeks of your cycle, take two pills the day you remember and 2 pills the next day, then take one pill a day until you finish the pack. Use a second method of birth control if you have sex in the 7 days after you miss the pills.
If you miss 2 pills in a row during the third week of your cycle or 3 or more pills in a row anytime in your cycle and you start your pills on Sunday, keep taking one pill a day until Sunday. On Sunday, safely discard the rest of the pack and start a new pack that day. You may not have a period this month. If you miss 2 periods in a row, call your doctor or clinic.
If you miss 2 pills in a row during the third week of your cycle or 3 or more pills at any time during your cycle and you start your pills on Day 1, safely dispose of the rest of the pill pack and start a new pack that same day. Use another method of birth control if you have sex in the 7 days after you miss the pills. You may not have a period this month. If you miss 2 periods in a row, call your doctor or clinic.
If you are not sure what to do after missing pills, contact your doctor or pharmacist for advice.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
The information provided here results from studies of combination oral contraceptives; the patch contraceptive is thought to have similar risks. Oral combination contraceptives increase the risk of the following serious conditions:
- blood clots
- gallbladder disease
- heart attack
- liver tumours
The risk of disease or death from these conditions greatly increases if a woman has other risk factors such as high blood pressure, high cholesterol, obesity, or diabetes.
Smoking while taking oral contraceptives increases the risk of side effects that affect the heart and blood vessels (e.g., blood clots). This risk is greatest for women 35 years and older. You should not take this medication if you smoke and are 35 years or older.
You should stop using the patch immediately if you develop any of the following:
- blood clot disorders and cardiovascular disorders (e.g., inflammation of a vein due to blood clot, blood clot in your lung)
- a condition that makes you immobile for a long period of time (e.g., recovering from major surgery, being bedridden due to a long-term illness)
- vision or eye problems (e.g., double vision, certain eye conditions) – check with your doctor
- severe headache without known cause, or worsening of preexisting migraine
Body weight: For women weighing 90 kg (198 lbs.) or more, the patch may be less effective. Check with your doctor for more information.
Breast self-exam and physical exams: Women taking this medication should do regular breast self-exams and have yearly physical exams done by their doctor.
Depression: Hormones, such as estrogen, have been known to cause mood swings and symptoms of depression. If you have had clinical depression in the past, you may be more likely to experience it again while taking this medication. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication contact your doctor as soon as possible.
Heat sources: Do not expose the patch area to heat sources such as heating pads, electric blankets, saunas, hot tubs, or heat lamps. This may increase the amount of medication that enters your body through the skin.
Sexually transmitted infections: Birth control patches do not protect against sexually transmitted infections, including HIV/AIDS. For protection against these, use latex condoms.
Pregnancy: This medication should not be taken during pregnancy. You should stop using this medication if you become pregnant and contact your doctor.
