Femlyv (Millicent), an orally disintegrating tablet containing ethinyl estradiol and norethindrone acetate, has been approved by the FDA for prevention of pregnancy in females with a body mass index (BMI) ≤35 kg/m². It is the first hormonal contraceptive to become available in an orally disintegrating tablet formulation. Traditional oral and chewable tablets containing ethinyl estradiol and norethindrone acetate in a wide range of doses, including those found in Femlyv, have been available in the US for years.

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

The FDA has approved Twirla (Agile Therapeutics), a transdermal contraceptive patch containing the estrogen ethinyl estradiol and the progestin levonorgestrel, for use in women with a BMI <30 kg/m². It is the second contraceptive patch to become available in the US; Xulane, a patch that delivers ethinyl estradiol and the progestin norelgestromin, has been available since 2014.

The FDA has approved Phexxi (Evofem), a nonhormonal prescription-only vaginal gel containing lactic acid, citric acid, and potassium bitartrate, for prevention of pregnancy. The gel is intended for on-demand contraception; it is not effective when used after intercourse. It was previously approved for use as a vaginal lubricant (Amphora), but was never marketed.

Annovera (TherapeuticsMD), a contraceptive vaginal ring that releases segesterone acetate, a synthetic progestin, and ethinyl estradiol, was approved by the FDA in 2018 and is now available. It is the first product to contain segesterone and the second vaginal ring to become available in the US; NuvaRing, which delivers etonogestrel and ethinyl estradiol, was the first. Unlike NuvaRing, which requires use of a new ring each month, the Annovera ring can be used for an entire year, but it must be removed for one week each month.

Intrauterine devices (IUDs) and the etonogestrel implant are the most effective reversible contraceptive methods available. Hormonal oral contraceptives, patches, rings, and injectables are also highly effective in preventing pregnancy. When used alone, barrier and fertility-based methods generally have higher failure rates than other methods.

Implants, intrauterine devices (IUDs), and sterilization are the most effective contraceptive methods available. Pills, patches, rings, and injectables, when used correctly, are also highly effective in preventing pregnancy. Barrier and fertility-based methods have the highest rates of failure.

The FDA recently approved Skyla (Bayer), the first new intrauterine device (IUD) in the US in 12 years. It releases levonorgestrel, a synthetic progestin, over a period of 3 years. A table summarizing contraceptive methods available in the US appears on page 22.

Nexplanon (Merck), a modified version of the contraceptive implant Implanon (Merck), is now available in the US. Nexplanon contains 68 mg of the progestin etonogestrel and is bioequivalent to Implanon. Both products are single-rod subdermal contraceptives implanted into the inside of the upper arm; both provide reversible effective contraception for up to 3 years.1 Nexplanon has a redesigned preloaded applicator intended to make insertion easier and reduce the risk of improperly placed devices. Proper placement is necessary to ensure adequate contraceptive efficacy and to facilitate future removal of the implant. Unlike Implanon, Nexplanon is radiopaque (contains barium sulfate) and can be located using an X-ray or CT scan when the device is not palpable. Providers should receive training before inserting or removing Nexplanon. Nexplanon will replace Implanon once all registered providers have completed the training program. The wholesale acquisition cost of a single Nexplanon implant is $659.42.2
