Product Overview
Weekly combined contraceptive patch (norelgestromin/ethinylestradiol). 3 weeks on, 1 week off. Prescription only. No STI protection.
Description
Evra transdermal contraceptive patch is a prescription-only combined hormonal contraceptive (CHC) used to prevent pregnancy. Each patch releases norelgestromin and ethinylestradiol through the skin over 7 days.
Evra works mainly by:
- preventing ovulation (release of an egg),
- thickening cervical mucus, and
- changing the lining of the womb.
Important: Evra does not protect against sexually transmitted infections (STIs).
How to Use
Always use exactly as directed by your prescriber and the patient leaflet.
Standard schedule (weekly patch)
- Apply 1 patch and wear for 7 days.
- Change to a new patch on the same day each week for 3 weeks (3 patches total).
- Then have 7 patch-free days (week 4). A withdrawal bleed usually occurs during this week.
- Start the next cycle after the 7-day break, even if bleeding hasn’t stopped.
Where to apply
Apply to clean, dry, intact skin on areas such as the buttock, abdomen, upper outer arm, or upper torso (not breasts). Rotate sites and press firmly to ensure good adhesion.
If the patch comes loose or falls off
What to do depends on how long it has been detached. Follow the leaflet instructions carefully and use backup contraception if advised.
