Hormonal%20contraception Patient Education

Patient Education

Combined Oral Contraceptives (COCs)

  • COC may be used from menarche to menopause
  • If COC is started initially between days 1-5 of the menstrual cycle, there is no need for additional contraception
    • If started beyond this period, pregnancy should be excluded and additional contraception for 7 days is advised
  • Ovulation is effectively inhibited after COC use for 7 consecutive days
  • COC should be taken every day, at around the same time, for 21 consecutive days followed by 7 steroid-free days
    • Women using a 21-day preparation should be cautioned not to exceed the 7-day pill-free interval
  • If COC pill is taken >24 hours after the scheduled time, it is considered missed
    • For missed dose, the pill should be taken as soon as it is remembered and subsequent pills taken at the usual time
    • Delaying the start of COC by >24 hours or missing one or more doses of COC during the 1st week may decrease protective contraception
    • Use back-up contraception (eg abstinence, condom use) with missed doses in the 2nd or 3rd week of hormone use until the COC has been used for 7 consecutive days 
    • Eliminate hormone-free interval when 1 or more days of COCs are missed in the 3rd week to maintain contraception then start taking pills from the next pack
  • Contraception is not needed in the 1st 3 weeks after childbirth and it is not recommended because there is increased risk of venous thromboembolism (VTE)
  • Non-breastfeeding women should start COC 21 days postpartum
    • If started beyond this, additional contraception is needed for 7 days
  • Women should be informed on symptoms which would prompt immediate medical consultation (eg warning signs of VTE, headache, eye problems, jaundice, abdominal pain)
  • Follow-up visit 3 months after the 1st prescription of COC to assess BP, medical problems, and give further instructions
  • Fertility is restored within 1-2 weeks after stopping the combined OC
    • Post-pill amenorrhea is more common in women with history of very irregular menstruation but rarely persists up to 6 months

Combination Injectable Contraception

  • Administered with no more than 33 days between injections, though can be given 7 days early or late from scheduled date  
  • If started within 7 days after the start of monthly bleeding, there is no need for a back-up contraception  
    • If started beyond this period, pregnancy should be excluded and back-up contraception is advised for the 1st 7 days after the injection  
  • Return to fertility is rapid and may be as soon as 6 weeks after the last injection

Combination Transdermal Patch

  • Patch is applied to clean, dry, hair-free skin on the buttock, abdomen, upper outer arm, or upper torso on the same day each week 
    • Avoid placing the patch on exactly the same site for 2 consecutive weeks

  • New patch is applied every week for 3 weeks, followed by 1 patch-free week
  • If patch change is delayed by up to 48 hours in the middle of the cycle, there is no need for additional contraception
  • If the patch-free interval is >9 days, a new patch should be applied and back-up contraception for 7 days should be used
  • Early detachment of the patch and delayed removal or application are considered missed or incorrect use of contraception
  • Avoid adhesive bandages, tattoos or decals on top of the patch which may affect absorption of hormones
  • Same return of fertility as COC after discontinuing the method

Combination Vaginal Ring

  • Ring is inserted into the vagina within the first 5 days of menstruation and left in place for 3 weeks (1 cycle)
