After taking emergency contraception, the birth control patch should be used with specific timing and backup methods to ensure effectiveness. If ella was taken, wait at least 6 days after unprotected sex before starting the patch. If Plan B or another levonorgestrel pill was taken, the patch can begin immediately. In both cases, use a backup method like condoms for the first 7 days. The patch follows a weekly cycle: apply a new patch on day 1, change it on day 8, and repeat for 3 weeks, followed by a patch-free week. Proper application involves clean, dry skin on approved body areas, avoiding irritation-prone spots. Effectiveness may decrease for those over 198 lbs or with a BMI ≥30.
Key Points Explained:
-
Timing After Emergency Contraception
- Ella (ulipristal acetate): Delay starting the estradiol td patch for at least 6 days after unprotected sex.
- Levonorgestrel pills (e.g., Plan B): Begin the patch immediately.
- Backup protection: Use condoms for the first 7 days of patch use, regardless of the emergency pill type.
-
Patch Application Cycle
- Week 1: Apply the first patch on day 1 (or after the 6-day wait for ella).
- Week 2–3: Replace the patch every 7 days (e.g., day 8, day 15).
- Week 4: Take a patch-free week to allow menstruation.
- Restart: Apply a new patch after 7 patch-free days, even if bleeding continues.
-
Proper Application
- Location: Apply to clean, dry skin on the abdomen, buttocks, upper arm, or torso (avoid breasts).
- Adhesion: Check daily to ensure it stays attached; avoid areas prone to rubbing.
- Storage: Keep patches sealed at room temperature until use.
-
Effectiveness Considerations
- Weight/BMI: Reduced efficacy for users >198 lbs (90 kg) or BMI ≥30.
- Hormonal interactions: Emergency contraception may temporarily disrupt cycle timing—track changes.
-
Tips for Success
- Set weekly reminders (phone alarms, calendar notes).
- Partner with someone to help remember change days.
- Avoid lotions or creams on application sites to prevent adhesion issues.
