As of 1994, there were approximately 47 progestin-containing contraceptive dmg formulations sold in the United States for use as oral contraceptives (Table 3). In addition, there are three nonoral contraceptive formulations containing progestins ie, one injectable (Depo-Provera), one as an intrauterine device (lUD) (Progestasert), and one implantable (Norplant). Of the oral formulations, all but two also contain an estrogen component, ethynylestradiol. 

Drug-drug interactions are often more problematic with carbamazepine than other mood stabilizers. Carbamazepine increases the activity of certain liver enzymes. Because these enzymes metabolize and eliminate medications and other substances introduced to the body, carbamazepine therapy can decrease the blood level and thereby reduce the effectiveness of itself (a phenomenon called autoinduction) and other medications that are metabolized by these enzymes. It is not unusual to find that the dose of carbamazepine must be increased after several weeks, because it has increased its own elimination. Other medications may likewise be less effective. Of particular concern are the oral contraceptives, Depo-Provera, and protease inhibitors used for the treatment of HI V+ patients. Oral contraceptives often require an increase in dose.

Medroxyprogesterone acetate and its metabolites are excreted in breast milk, so women who breastfeed should wait until 6 weeks post partum before starting Depo-Provera, when the infant s enzyme system should be more mature. Norethisterone enantate 200 mg (Noristerat) is shorter acting than Depo-Provera, 8 weeks, and is used to provide contraception after administration of the rubella vaccine, and until a partner s vasectomy has taken effect. It can also be used in the longer-term but only on a named patient basis.
