Contraceptive efficacy, cycle control and side effects of two types of 0.75 mg levonorgestrel tablets taken postcoitally during the periovulatory period of one cycle were studied in a multicenter trial involving 361 women. No significant differences were found between the two types of levonorgestrel pills in terms of contraceptive efficacy, cycle control and side effects. The failure rate observed (1.4% per treated cycle) was similar to that reported for other hormonal approaches to emergency postcoital contraception. Intermenstrual bleeding or spotting occurred in 11.5% of the cycles and anovulation as assessed from BBT charts in 14.4% of cycles. One or more side effects were reported by 22.2% of subjects. The relatively frequent occurrence of cycle disturbances and subjective side effects make it unlikely that the repeated postcoital use of levonorgestrel would be an acceptable routine method of contraception for most women.

Concerns about abnormal menstrual bleeding are a common reason for women to consult a primary care physician. The first step in the evaluation is to determine the patient's ovulatory status. Women with heavy bleeding but normal ovulatory cycles should be evaluated for coagulopathies, structural lesions, and hypothyroidism. In the absence of a systemic or structural cause, menorrhagia can be treated with OCPs or NSAIDs. Intermenstrual bleeding in OCP users may be due to noncompliance or the use of low-dose pills. Encouraging patient compliance and adjustment of the estrogen dose can often solve the problem. If the patient is not on OCPs, intermenstrual bleeding is usually due to a structural or inflammatory lesion. The differential diagnosis for anovulatory bleeding is extensive. Pregnancy, systemic illnesses, and structural lesions should be ruled out by history, physical examination, and laboratory evaluation. Endometrial biopsy is indicated in patients over age 35 and younger patients with risk factors for endometrial cancer, such as chronic anovulation and obesity. Dysfunctional uterine bleeding is a nonspecific term for abnormal uterine bleeding in the absence of systemic or structural disease. It is usually associated with anovulation. Adolescents frequently have dysfunctional uterine bleeding owing to immaturity of the hypothalamic-pituitary-ovarian axis. Perimenopausal women have an increased incidence of irregular bleeding secondary to decreased estrogen production by the ovary. Obesity, polycystic ovary syndrome, stress, crash diets, and vigorous exercise can all disrupt normal ovulatory function. Treatment options for dysfunctional uterine bleeding include oral contraceptives, cyclic progesterone, or hormone replacement with estrogen and progesterone. Patients with structural lesions or those who do not resume normal withdrawal bleeding patterns on hormone therapy should be referred to a gynecologist for further evaluation and treatment.
