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..
You 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.

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

Lo / Ovral-28 (Norelgestromin/Ethinyl Estradiol) Dosing Information
Usual Adult Dose for Contraception:
The initial dosage of ethinyl estradiol-norelgestromin transdermal patch for contraception is the placement of one patch on the skin of the upper outer arm, or abdomen, or buttocks, weekly for 3 weeks (21 total days), which is to remain in place for 7 days, the fourth week is drug free.
A new transdermal patch is placed on the skin one-week after the last patch was removed. Regardless of withdrawal bleed presence, the new transdermal patch is placed on the skin the same day (at any time) as it was done in the previous cycle.
If a patch is partially or completed detached for less than 1 day (up to 24 hours), reapply it to the same place or replace it with a new patch immediately. No backup contraception is needed. If this event occurs for more than 1 day (24 hours or more), or if the woman is not sure how long the patch has been detached, she should stop the current contraceptive cycle and start a new cycle immediately by applying a new patch. Backup contraception, such as condoms, spermicide, or diaphragm, must be used for the first week of the new cycle.
In women switching from a combination oral contraceptive, begin use of the patch on the first day of withdrawal bleeding. If there is no withdrawal bleeding within 5 days of the last active (hormone-containing) tablet, pregnancy must be ruled out. If the patch is placed later than the first day of withdrawal bleeding, but within the 7 days from the last oral active tablet, a second method of contraception (non-hormonal) should be added for the first 7 days.
In women with a miscarriage or a complete first trimester abortion, begin use of the patch immediately. An additional method of contraception would not be needed if therapy is started immediately.
In women who choose not to breast-feed after childbirth, begin use of the patch no sooner than 4 weeks after childbirth. Postpartum women who have not had a period should add a second method of contraception (non-hormonal) for the first 7 days of patch use.
