Q

MOA of combined hormonal contraceptives

A

Estrogen & Progesterone work synergistically (estrogen regulates the cycle, progesterone stops conception)

  • continuous levels of estrogen & progesterone suppress FSH & LH
  • progesterone suppresses LH to prevent the mid-cycle surge & stop ovulation
  • progesterone thickens cervical mucus to impair sperm travel
  • estrogen suppresses FSH to prevent the selection & emergence of a dominant follicle

A

All forms of progesterone can exhibit some estrogenic, androgenic & anabolic activity

  • estrogenic: increases estrogen
  • androgenic: produces male characteristics (Desogestrel & norgestimate are less androgenic)
  • anabolic: testosterone effects

Q

Combined hormonal contraceptive medication interactions

A

Use backup method for the duration of treatment plus 7 extra days (if med is long term, new form of contraception is needed)

Q

Depo-provera

A

MOA: suppresses ovulation & changes cervical mucus; inhibits secretion of LH & FSH; suppresses estradiol levels (which can lead to decreased bone mass)

  • should be given every 12 weeks (-2 or +1 week cushion)
  • IM injection
  • document weight & BP at visits (depo can increase both)
28
Q

Long-Acting reversible contraception (LARCs)

Hormonal methods:
-IUD: intrauterine device
-Nexplanon: implantable devices
Non-hormonal methods: Paragaurd (IUD)

29
Q

IUD Mechanism of Action

A

  • Mirena, Kyleena & Liletta: 5 years
  • Skyla: 3 years
32
Q

Contraindications: pregnancy, active liver disease or active venous thromboembolism

34
Q

Hormonal LARC comparison

A

Hormonal IUDs: 3 or 5 years, in the uterus, irregularities in menstrual bleeding, doesn’t protect against STIs, few contraindications
Nexplanon: 3 years, in the arm, irregularities in menstrual bleeding, contraindicated in active liver disease & active venous thromboembolism

35
