The FDA now requires that product labels for the long-acting injectable progestin contraceptive medroxyprogesterone acetate (MPA; Depo-Provera CI, and generics; Depo-SubQ Provera 104) include a warning about the risk of meningioma associated with its use.

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 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.

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.

Transdermal, transvaginal and intrauterine hormone delivery systems have made highly effective contraceptive products more convenient to use. New oral contraceptive options include regimens with fewer or shorter hormone-free intervals.

In recent years, several new contraceptive options have become available in the United States. Novel hormone delivery systems such as transdermal, transvaginal and intrauterine devices have improved the convenience of highly effective contraceptive products. Like oral contraceptives and most barrier contraceptives, these devices do not protect against sexually transmitted diseases.

The tables that follow list drugs used for treatment of cancer in the USA and Canada and their major adverse effects. The choice of drugs in Table I is based on the opinions of Medical Letter consultants. Some drugs are listed for indications for which they have not been approved by the US Food and Drug Administration. For most of the cancers listed, surgery and/or radiation therapy are part of the management of the disease. Anticancer drugs and their adverse effects are listed in Table II.
