ethinyl estradiol and norelgestromin (cont.)
What happens if I miss a dose (Ortho Evra)?
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.
What happens if I overdose (Ortho Evra)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include nausea, vomiting, and vaginal bleeding.
