How to Use Them

Debunking the “Fifth-Day Start” Myth

Historically, it was thought that starting a contraceptive on the fifth day of the menstrual cycle offered optimal protection. Modern evidence indicates that starting any time in the cycle provides effective contraception after seven days of consistent use, so starting on the first day of the menstrual cycle will offer the optimal 7 days for maximum protection.

General Usage Guidelines for Combined Oral Contraceptives (COCs)

• Daily Intake: Take one pill at the same time every day.
• Starting the Pack:
  • Day 1 Start: Begin on the first day of your period for immediate protection.
  • Sunday Start: Begin on the first Sunday after your period starts; use backup contraception for the first 7 days.
• Cycle: Typically involves 21 active pills followed by 7 placebo or pill-free days (28-day cycle).
• Next Pack: Start the next pack immediately after the 7-day break, even if your period hasn't started or is still ongoing. This ensures continuous protection.

Specific Considerations

Gracial

• Sequential Pills: Pills come in different colors with varying hormone doses. Follow the order precisely.
• Cycle: Usually a 22-day cycle followed by a 6-day break.

Cerazette (Progestogen-Only Pill)

• Continuous Use: Take one pill at the same time every day without any breaks between packs.
• Timing: Consistency is crucial; try not to vary the time by more than 12 hours.

Evra Patch

• Application:
  • Weeks 1-3: Apply a new patch once a week on the same day.
  • Week 4: No patch is worn; expect a withdrawal bleed.
• Placement: Apply to clean, dry, and hairless skin on the abdomen, buttocks, upper outer arm, or upper torso (excluding breasts).
• Next Cycle: Start a new patch cycle after the patch-free week, even if bleeding hasn't occurred.

What to Do If You Miss a Dose

Missed Pills: Timing Matters

• If Less Than 12 Hours Late:
  • Action: Take the tablet as soon as remembered and continue subsequent tablets at the usual time.
  • Protection: Maintained; no backup needed.
• If More Than 12 Hours Late:
  • Protection may be reduced. The risk increases with the number of missed tablets and proximity to the start or end of the strip.

Specific Guidelines:

1. More Than One Tablet Missed in the Strip:

   • Action: Contact a healthcare provider for guidance.

2. One Tablet Missed in Week 1:

   • Action: Take the missed tablet immediately, even if it means taking two tablets in one day. Continue as normal.
   • Protection: Use backup contraception for seven days.
   • Consideration: If unprotected intercourse occurred in the previous seven days, consider emergency contraception.

3. One Tablet Missed in Week 2:

   • Action: Take the missed tablet immediately. Continue as normal.
   • Protection: Maintained; no backup needed.

4. One Tablet Missed in Week 3:

   • Option 1:
     • Take the missed tablet immediately.
     • Finish the active tablets and start the next pack without a pill-free interval.
     • Benefit: Maintains protection without the need for backup contraception.
   • Option 2:
     • Discontinue active tablets.
     • Begin the seven-day pill-free interval immediately.
     • Start a new pack after the interval.
     • Note: This may alter the usual start day.

Key Counseling Points:

• Emphasize Timing: The sooner the missed pill is taken, the better.
• Backup Contraception: Advise when additional protection is necessary.
• Emergency Contraception: Consider if unprotected intercourse occurred, especially during Week 1.

Cerazette (Progestogen-Only Pill)

• If Less Than 12 Hours Late:
  • Action: Take the missed tablet immediately and continue as normal.

  • Protection: Use backup contraception for the next two days.

Evra Patch

• Delayed Application or Detached Patch:

  • Less Than 48 Hours:
    • Action: Reapply the same patch or apply a new one immediately.
    • Protection: Maintained; no backup needed.

    • Week 1:
      • Action: Apply a new patch immediately (this becomes the new Day 1).
