How should I use ethinyl estradiol and norelgestromin?

Use exactly as prescribed by your doctor. Do not use more skin patches or wear them for longer than recommended by your doctor. You will apply your first patch on the first day of your period or on the first Sunday after your period begins (follow your doctor's instructions).

Place the patch on your skin and press it into place firmly for 10 seconds. Make sure the edges stick well. You will wear the patch for a full week.

Apply the patch to clean, dry skin on any of these areas: the outside of your upper arm, your stomach, your buttocks, or your upper back. Do not apply the patch to skin that is broken or irritated, or to a skin area that may be rubbed by tight clothing (such as a waistband).

Remove the patch and apply a new one on the same day each week for three weeks in a row. At the end of the third week, remove the patch and do not apply a new one for 7 full days. Your period should start during this time Do not allow more than 7 days to pass before starting your next 3-week patch cycle..

emtYou may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.

Check your patch every day to make sure it is sticking well. If a patch comes loose or falls off, throw it away and apply a new one. You may need to use back-up birth control, such as condoms or a spermicide, if a patch has been off for more than 24 hours. Follow your doctor's instructions.

After removing a skin patch fold it in half, sticky side in, and throw it away in a place where children and pets cannot get to it. Do not flush a used patch down the toilet.

If you need to have any type of medical tests or surgery, or if you will be on bed rest, tell the doctor or surgeon ahead of time that you are using this medication. You may need to stop wearing the patches for a short time.

Your doctor will need to see you on a regular basis while you are using this medication. Do not miss any appointments.

rtStore the skin patches at room temperature away from moisture and heat. Do not freeze or refrigerate. Keep each patch in its foil pouch until you are ready to apply it.

What happens if I miss a dose?

If you forget to change your patch at the end of the week, change it as soon as you remember. If it has been 24 hours or longer since your scheduled patch change, apply a new patch and start the cycle over (3 weeks wearing a weekly patch,1 week off). Do not use extra patches to make up the missed dose.

Missing a dose increases your risk of becoming pregnant and you may need to use back-up birth control. Follow the weekly patch schedule closely.
