Outlined is a protocol for the administration of emergency contraceptive pills. The indication for such treatment is unprotected intercourse within the past 72 hours. Absolute contraindications include the possibility of an existing pregnancy and a family history of
stroke
, heart attack, thrombophlebitis, breast or endometrial cancer, or liver tumor. Possibly excluded, depending on evaluation by a physician, are women with abnormal vaginal bleeding, active hepatitis, active gallbladder disease, high blood pressure, acute focal migraine, breastfeeding women, and those unable to understand instructions. The recommended regimen consists of six tablets of
Ovral
(two taken immediately, two more in 12 hours) or 12 tablets of
Lo/Ovral
,
Nordette
, or
Levlen
(four taken immediately, repeat dosage in 12 hours). The extra pills are to be used in cases of vomiting within three hours of pill ingestion. Women with a history of oral contraceptive-related nausea and vomiting should be provided with Compazine. Women should be informed that this method is effective in only about 92% of cases. All women who receive emergency contraception should be counseled that this is strictly a back-up method and helped to formulate a long-term birth control strategy.

New types of contraception approved for use in the US include two long-lasting, hormone-based contraceptives, Depo-Provera and
Norplant
, and the female condom. The female condom is made of polyurethane, which is thinner, stronger, and a better conductor of heat than latex. Its inner ring fits over the cervix and the outer ring protects the labia and the base of the penis. Its typical-use and perfect-use failure rates are 21-26% and around 5%, respectively. One injection of Depo-Provera blocks ovulation for 3 months. Irregular periods are common with Depo-Provera use. Fertility may not return for 6-12 months after discontinuation. Depo-Provera may protect against endometrial cancer. The 6-capsule system
Norplant
is inserted subdermally in the arm and releases levonorgestrel for up to 5 years. Since its arrival on the US market, more than 900,000 women have used
Norplant
. Contraindications to
Norplant
are liver disease, blood clots, inflammation of the veins, history of breast cancer, or breast feeding in the first 6 weeks postpartum. More than 600,000 US women undergo sterilization annually. 25% of all heterosexually active, fertile women of reproductive age and 60% of these women ages 35-44 have had a tubal ligation. Vasectomy is less risky than tubal ligation. Both vasectomy and tubal sterilization are more than 99% effective. Oral contraceptives (OCs) suppress ovulation. 28% of US women of reproductive age use OCs. OCs are more than 99% effective. OCs appear to increase the risk of blood clots, heart attack, and
stroke
for smokers over 35. Health benefits of OCs include protection against ovarian cancer, endometrial cancer, pelvic inflammatory disease, ovarian cysts, and benign breast tumors. Barrier methods keep sperm from joining the egg. Latex condoms protect against sexually transmitted diseases (STDs). IUDs interfere with sperm transport and egg fertilization. In the US, there is a perception that IUD use is unsafe. Women with new or multiple partners should use condoms to protect against STDs.

Legal action has been taken in several US cities against Wyeth-Ayerst's
Norplant
, claiming that labels were deceptive regarding the potential side effects and the difficulties possible with removal. All the lawsuits claimed suffering caused by removals. 25 women in Miami, Florida, filed suit for $50,000 each in damages due to difficult removal. 8 women from Maryland joined 600 women filing in Chicago, who seek $20,000 to $50,000 for damages due to difficult removals and scarring. The group of plaintiffs also have asked for an injunction preventing the company from selling
Norplant
to doctors without proper training. Wyeth-Ayerst reported that it requested label changes before the lawsuits were filed. The label now states that removals and insertions are possible, without designating the time allocation required; prior labels indicated a 15-20 minute period. The new label includes possible side effects of emotional instability, heart attack,
stroke
, migraine, arm pain, numbness and tingling. One Maryland woman requested removal because the capsules had shifted and one had moved from her upper arm to under her armpit. Removal required 3 stages totaling 3 hours and ultrasound detection. Another women gained 20 pounds and had a sore arm.
Norplant
was first introduced in the US in 1991 after 20 years of experience with use worldwide. The contraceptive is effective for 5 years after insertion of 6 capsules, with slow releasing hormones. Planned Parenthood of Maryland administers
Norplant
at 7 clinics throughout the state, by practitioners at several clinics, and by the Baltimore City health department in school-based clinics. City clinics since 1991 have made 198 insertions and 14 removals, with no problems with removals. School-based clinics have inserted 45 implants and no removals. Bayview Clinic in Baltimore has made 2000 insertions and 250 removals, with few difficulties. The chief of obstetrics and gynecology at Bayview said that it takes about 6 times before removal is perfected by even a trained doctor. The Population Council, which developed
Norplant
and licensed it to Wyeth-Ayerst, still supports it as one of the most effective, reversible methods of birth control.

Oral contraceptive pills (OCs) are widely used method of contraception for its effectiveness and easier compliance. However, adverse effects associated with OCs use notably the increased risk of cardiovascular diseases (CVD), manifesting as ischaemic and haemorrhagic
stroke
, myocardial infarction (MI) and venous thromboembolic diseases were reported soon after their introduction to the market in the early 1960s. Various modifications were made in an attempt to lower these risks including a reduction in the estrogen dose and changes in the progestogen compound. Currently used OCs containing the new progestin (
Levonorgestrel
, Desogestrel, gestodene or norgestimate) classified as low dose because all contain less than 35 microg of ethinyl estradiol. Despite their low steroid content, all have proved to be highly effective. The rationale of this reviewed study based upon cardiovascular risks in relation to these monophasic low-dose oral contraceptives. To review all relevant articles it is concluded that the risk for cardiovascular disease is lower with current preparations of oral contraceptives. Cardiovascular diseases occur mainly among oral contraceptive users who smoke or have predisposing factors--such as age more than 35 years, overweight, diabetes & hypertension.

Primary care physicians often prescribe contraceptives to women of reproductive age with comorbidities. Novel delivery systems (e.g., contraceptive patch, contraceptive ring, single-rod implantable device) may change traditional risk and benefit profiles in women with comorbidities. Effective contraceptive counseling requires an understanding of a woman's preferences and medical history, as well as the risks, benefits, adverse effects, and contraindications of each method. Noncontraceptive benefits of combined hormonal contraceptives, such as oral contraceptive pills, include regulated menses, decreased dysmenorrhea, and diminished premenstrual dysphoric disorder. Oral contraceptive pills may be used safely in women with a range of medical conditions, including well-controlled hypertension, uncomplicated diabetes mellitus, depression, and uncomplicated valvular heart disease. However, women older than 35 years who smoke should avoid oral contraceptive pills. Contraceptives containing estrogen, which can increase thrombotic risk, should be avoided in women with a history of venous thromboembolism,
stroke
, cardiovascular disease, or peripheral vascular disease. Progestin-only contraceptives are recommended for women with contraindications to estrogen. Depo-Provera, a long-acting injectable contraceptive, may be preferred in women with sickle cell disease because it reduces the frequency of painful crises. Because of the interaction between antiepileptics and oral contraceptive pills, Depo-Provera may also be considered in women with epilepsy. Implanon, the single-rod implantable contraceptive device, may reduce symptoms of dysmenorrhea.
Mirena
, the levonorgestrel-containing intrauterine contraceptive system, is an option for women with menorrhagia, endometriosis, or chronic pelvic pain.
