Contraceptive Options for Women and Couples with HIV Implants, POPs and Emergency Contraception Subdermal Implants • Progestin-filled rods or capsules that are inserted under the skin • Norplant: 6-capsule system, effective for 5 years • Second generation implants – Jadelle and Sinoplant: 2-rod system, effective for 5 years – Implanon: 1-rod system, effective for 3 years • Mechanism of action similar to injectables Implants – Characteristics Advantages Disadvantages • Safe, 99.95% effective, easy to use, reversible • Have common side effects • Can be used by breastfeeding women • Cannot be initiated/ discontinued without provider’s help • Offer health benefits, such as reducing risk of symptomatic PID and anemia • Provide no protection from STIs/HIV Source: Hatcher, 2007; WHO, 2004, updated 2008; CCP and WHO, 2007. Implants – Side Effects • First several months: light bleeding/spotting, prolonged irregular bleeding, infrequent bleeding, amenorrhea • After one year: light bleeding for fewer days, irregular bleeding, infrequent bleeding, amenorrhea • Other side effects: nausea, headaches, breast tenderness, weight change, abdominal pain – less common than with progestin-only injectables – diminish after the first few months Source: Shoupe, 1991; CCP and WHO, 2007. Category 1 and 2 Examples (not inclusive): Who Can Use Implants WHO Category Conditions Category 1 breastfeeding after 6 weeks postpartum, heavy smokers, complicated valvular heart disease, endometriosis, endometrial or ovarian cancer, thyroid disorders Category 2 blood pressure ≥160/100, history of DVT/PE, diabetes with vascular complications, heavy or prolonged vaginal bleeding patterns, multiple risk factors for CVD Source: WHO, 2004; updated 2008. Category 3 and 4 Who Should Not Use Implants WHO Category Conditions Category 3 breastfeeding before 6 weeks postpartum, acute DVT/PE, unexplained vaginal bleeding, history of breast cancer, severe liver disease and most liver tumors, systemic lupus disease continuation only: ischemic heart disease, stroke, migraine with aura Category 4 current breast cancer Source: WHO, 2004; updated 2008. Implant Use by Women with HIV WHO Eligibility Criteria Condition Category HIV1 infected AIDS 1 ARV therapy 2 • Women with HIV or AIDS can use without restrictions • Some ARV drugs reduce blood progestin level • Efficacy is not affected because implants provide consistent dose of hormone over time • Dual method use should be encouraged Source: WHO, 2004, updated 2008; Mildvan, 2002. Progestin-Only Pills (POPs) • Contain no estrogen • Less progestin than COCs • All pills in pack are active • Progestin amount same throughout • 28-35 pills per pack • Eligibility criteria is similar to those of implants POPs are especially suitable for breastfeeding women and others who should not use estrogen. Source: WHO, 2004; updated 2008. Progestin-Only Pills (POPs) continued … • Mechanism of action: – partial suppression of ovulation (more pronounced in breastfeeding women) – thickening of cervical mucus • Have no known adverse effects • Side effects are similar to those of implants – irregular or prolonged bleeding is not common in breastfeeding women • Require stricter pill-taking schedule than COCs – 1 pill each day within 3 hours of same time – no breaks between packs Source: CCP and WHO, 2008 update. * within 12 hours for POPs containing desogestrel 75μg POPs – Missed Pills • Take most recent missed pill as soon as possible • Abstain or use backup method for 48 hours • Take next pill at regular time • Consider use of emergency contraception if appropriate • No backup method or emergency contraception needed if pills are missed by a woman who is still protected by LAM Source: CCP and WHO, 2008 update. POP Use by Women with HIV Category • Women with HIV or AIDS can use without restrictions HIV-infected 1 • Women on ARVs other than ritonavir can use POPs safely AIDS 1 • Should not be used by women who take ritonavir 2 • Dual method use should be encouraged WHO Eligibility Criteria Condition ARV therapy (which does not contain ritonavir) Ritonavir/ ritonavirboosted PIs 3 (as part of ARV regimen) Source: WHO, 2004, updated 2008; Sekar, 2008. • Breastfeeding status provides additional protection from pregnancy ECP Use by Women with HIV • Use to prevent pregnancy after unprotected intercourse – progestin-only and combined estrogen-progestin regimens – start as soon as possible; counsel to adopt regular method • Use if regular method was used incorrectly, failed, or was not used • Safe for all women (including women with HIV/AIDS and taking ARV drugs) There is no evidence to justify changes to emergency contraceptive pill regimens for ARV clients. Source: Hatcher, 2007; WHO, 2004, updated 2008. ECP Pill Regimens: Progestin-Only Oral Contraceptives Start within 120 hours (5 days) after unprotected intercourse pills formulated as emergency contraception regular progestinonly pills 1.5 mg levonorgestrel or 3 mg norgestrel; take all at once or in two doses 12 hours apart Source: CCP and WHO, 2007; WHO Task Force on Postovulatory Methods of Fertility Regulation, 1998; Piaggio, 1999; von Hertzen, 2002. ECP Pill Regimens: Combined Oral Contraceptives Start within 120 hours (5 days) after unprotected intercourse low-dose pills* 12 hours Each dose should contain at least: 0.1 mg ethinyl estradiol and 0.5 mg levonorgestrel high-dose pills repeat dose 12 hours repeat dose Known as Yuzpe regimen *or 5 pills for each dose, if each pill contains 0.02 mg of ethinyl estradiol Most effective when used early.

ECPs – Key Counseling Messages • Use and effectiveness • More effective the sooner they are begun • Side effects (nausea and vomiting) may occur; less common with progestin-only regimen • Next menses may come a week early or late • Do not provide pregnancy protection for future intercourse or protection from STIs/HIV • After using, regular method should be considered
