Contraceptives nonhormonal

A comparison of methods of nonhormonal contraception is shown in Table 30-1. 

Affairs of the American Medical Association recommends that women be informed about the small risk of interactions with antibiotics, and, if desired, appropriate additional nonhormonal contraceptive agents should be considered. Women who develop breakthrough bleeding during concomitant use of antibiotics and CHCs should be told to use an alternate method of contraception during the period of concomitant use. 

First day start - For first day start, apply the first patch during the first 24 hours of the menstrual period. If therapy starts after day 1 of the menstrual cycle, a nonhormonal back-up contraceptive (eg, condoms, spermicide, diaphragm) should be used concurrently for the first 7 consecutive days of the first treatment cycle. 

Use after abortion or miscarriage - After an abortion or miscarriage that occurs in the first trimester, the patch may be started immediately. An additional method of contraception is not needed if the patch is started immediately. If use of the patch is not started within 5 days following a first trimester abortion, the woman should follow the instructions for a woman starting the patch for the first time. In the meantime, advise her to use a nonhormonal contraceptive method. Ovulation may occur within 10 days after an abortion or miscarriage. 

Note Advise patients using oral or other systemic hormonal contraceptives to change to nonhormonal methods of birth control. 

Hypersensitivity to the drug and to carbamazepine, alcohol. Recommend additional nonhormonal forms of contraception. 

A woman s reproductive life cycle spans nearly four decades. During this time her hormonal status and ability to reproduce vary considerably. The need for hormonal intervention during this time period varies from person to person and, typically, requires highly individualized medication regimens. The remainder of this chapter will focus on hormonal and selected nonhormonal therapies for the treatment and/or management of contraception, endometriosis, infertility, menopause, and breast cancer.
