The FDA has approved Opill (Perrigo), a progestin-only
oral contraceptive that contains norgestrel, for
sale over the counter (OTC). Opill is the first oral

to increase access to effective contraception and
reduce the rate of unintended pregnancies.

Intrauterine devices (IUDs) and the etonogestrel
implant are the most effective reversible contraceptive
methods available. Hormonal oral contraceptives,
patches, rings, and injectables are also effective in
preventing pregnancy. When used alone, barrier and
behavioral methods generally have higher failure
rates than other methods (see Table 1). Selection of
a contraceptive method is usually based on patient-specific factors and personal preference

Oriahnn (Abbvie), a fixed-dose combination of the
gonadotropin-releasing hormone (GnRH) receptor
antagonist elagolix, the estrogen estradiol, and the
progestin norethindrone acetate copackaged with
elagolix alone, has been approved by the FDA for oral
treatment of heavy menstrual bleeding associated
with uterine leiomyomas (fibroids) in premenopausal
women. It is the first product to be approved in the
US for this indication. Elagolix (Orilissa) has been
available since 2018 for treatment of moderate to
severe pain associated with endometriosis. The
GnRH receptor antagonist relugolix (Orgovyx), which is
approved for treatment of advanced prostate cancer,
is being reviewed by the FDA for use in combination
with estradiol and norethindrone acetate for the same
indication as Oriahnn.

use as a vaginal lubricant (Amphora), but was never
marketed.

The FDA has approved Liletta, an intrauterine
device (IUD) that releases the synthetic progestin
levonorgestrel, for prevention of pregnancy for up to
3 years. The fourth IUD to be approved in the US, and
the third that releases levonorgestrel, Liletta is
comarketed by Actavis and Medicines360, a nonprofit
women's health pharmaceutical company. The wholesale
cost of Liletta is similar to that of other IUDs (see
Table 1), but the manufacturer offers programs that
significantly reduce the cost for commercially-insured
patients and clinics serving low-income women.

In Brief: Warning about Drospirenone in Oral Contraceptives

The FDA has announced that combination hormonal contraceptives (CHCs) containing the synthetic progestin drospirenone (Yaz, Yasmin, Beyaz, Safyral, and others) may be associated with a higher risk of thromboembolism than CHCs containing other progestins.1
The new warning was based partly on an unpublished, FDA-funded, retrospective study that found a 1.7-times higher risk of venous thromboembolism among US women who used a CHC that contained drospirenone than among women whose CHC contained levonorgestrel, norgestimate or norethindrone as the progestin component.2 As with all retrospective studies, unknowable confounding factors, such as why doctors prescribed one progestin over the other, could have distorted the results.
All CHCs increase the risk of venous thromboembolism; whether the progestin component affects the risk has been controversial. The Medical Letter and several other reviews and consensus statements have found no convincing evidence of an increased risk with drospirenone.3-5

Combination oral contraceptives increase the risk of venous thromboembolism (VTE). Their benefits, in

The FDA has announced that it will lower the age for over-the-counter access to the emergency contraceptive Plan B1 from 18 to 17 years old. In a randomized, controlled trial, the two 0.75-mg levonorgestrel tablets in Plan B, taken 12 hours apart beginning within 72 hours after unprotected intercourse, decreased the overall pregnancy rate to 1.1% (11/976) of women who requested emergency contraception.2 The sooner the drug is taken after coitus, the more effective it is. Nausea and vomiting can occur with Plan B. Fetal malformations have not been associated with pregnancies that occurred despite use of levonorgestrel-only emergency contraception.3

Desogen (Organon) and Ortho-Cept (Ortho), two oral contraceptives each containing a low dose (30 mcg) of the estrogen ethinyl estradiol plus 150 mcg of the progestin desogestrel, were recently approved by the US Food and Drug Administration for marketing in the USA. They are the first US oral contraceptives to contain desogestrel, which is widely used in oral contraceptive combination products in other countries. Desogestrel is one of three new progestins (norgestimate and gestodene are the others) considered less androgenic than previously available progestins (L Speroff et al, Obstet Gynecol, 81:1034, June 1993).
