Ella - Ulipristal

Copper IUD - most efficient, off label

2

PO Levonorgestrel

Plan B - synthetic progesterone

No need for pregnancy test or exam

No contraindications

SE: N/V, irregular bleeding, dizzy, fatigue, HA, breast tenderness

Effective up to 120 hours -> 2-3% failure rate

Ineffective after ovulation occurred, doesn't interrupt pregnancy

3

Copper IUD

Paraguard

MOA: interfere w/ fertilization or tubal transport

Prevent transplant by altering endometrial receptivity

Copper interferes w/ sperm transport to prevent fertilization

Great alternative to hormonal methods

SE: heavy menses, dysmenorrhea

4

Oral Contraceptive Pills

Suppress GnRH to prevent LH surge; suppress FSH to prevent ovulation

Stabilize endometrium; progesterone thickens cervical mucus

Higher dose estrogen for spotting, recurrent ovarian cysts, acne

5

OCP Preparations

Monophasic

Multiphasic

Extended Cycle

Monophasic: no change in hormonal concentration throughout cycle

-usually start w/ these for younger or less compliant

Multiphasic: change in hormone concentration - biphasic or triphasic

Extended Cycle: take the same dose for 11 weeks then have period

-84/91 day cycle

-Seasonale, Introvale, Quasense

6

Starting OCP

Quick start: regardless of day of cycle

Sunday start: 1st sunday after period begins for 7 days

10

Progestin-only contraceptives & MOA

Depo medroxyprogesterone acetate

Progestin implant - Nexplanon

Progestin IUD - Mirena, Skyla

MOA: inhibit gonadotropin secretion, inhibits follicular maturation & ovulation, thickens cervical mucous, thins endometrium

SE: weight gain, decreased bone density - BBW

11

Progesterone Implants

Implanon/Nexplanon: 68 mg estronogestral rod in upper arm - lasts for 3 years

Jadelle: 2 levonorgestrel rods - lasts for 5 years

12

Progestin IUD/IUC

Lebonorgestrel - Mirena, Skyla

MOA: prevents fertilization w/ sterile inflammation from foreign body

May protect against endometrial cancer

SE: irregular bleeding, breast tenderness, acne, mood changes

13

Fertility Awareness Methods

Ovulation method: predict fertile time based on cycle length

Sympothermal: basal body temperature, cervical mucus used to track ovulation

Basal Body Temperature: increase 0.5-1.0 degrees F 2-3 days before
