Factors for consideration of Pill Versus Other Progestin-Only Methods
Efficacy:
2. Dosing frequency and convenience:
3. Resumption of fertility
4. Need for procedure:
If a patient is going to be receiving an interacting medication for more than 2 months, switch to
(DMPA) or an IUD
to avoid the interaction
Treatment of mild vaginal symptoms
nonhormonal lubricants and moisturizers
Side effects of POPS
- Irregular menses
- Ectopic pregnancy
- Acne
- Headache
- Nausea

A variety of progestin-only contraceptive methods exists
There are two progestin-only oral products available, norethindrone
“mini-pills” and drospirenone ”Slynd”.
* Etonogestrel subdermal implant.
* Levonorgestrel-releasing intrauterine devices (IUDs)
* Depot medroxyprogesterone acetate (DMPA) IM, SC injections
For individuals who cannot or prefer not to use estrogen-containing
contraception
estrogen-related side effects, hypertensive or
diabetic patients, smokers, older than 35, breastfeeding mothers, and
patient with history of DVT or CV complications)
Treatment of moderate to severe menopausal genitourinary syndrome
low-dose vaginal estrogen (topical) rather than systemic estrogen.
POPs need to be taken
injection
etonogestrel implant
levonorgestrel-releasing IUDs
daily and, ideally, at the same time of day
every 12-14 week
three to five years
three to six years
associated with a rapid return of fertility after method discontinuation (typically within one cycle)
POPs, the etonogestrel implant, and IUDs
Progestins provide most of the contraceptive effect by?
thickening cervical mucus to prevent sperm penetration, slowing tubal motility, delaying sperm transport, and inducing endometrial atrophy.
Progestins block the LH flow, to inhibit ovulation.
* Estrogens suppress FSH release from the pituitary, which may
contribute to blocking the LH flow to prevent ovulation.
The return of fertility with the ——-injection may take 6-12
months.
DMPA
The estrogen component in most combined hormonal contraceptives is
ethinyl estradiol
