Levonorgestrel [For emergency contraception] interactions

Food & lifestyle

• grapefruit juice

  Moderate

  Metabolism

  Grapefruit juice may increase the plasma concentrations of orally administered drugs that are substrates of the CYP450 3A4 isoenzyme. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.

  What to do: Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and altered plasma concentrations of drugs that undergo significant presystemic metabolism by CYP450 3A4. Grapefruit and grapefruit juice should be avoided if an interaction is suspected. Orange juice is not expected to interact with these drugs.

• alcohol

  Minor

  Metabolism

  The central nervous system effects and blood levels of ethanol may be increased in patients taking oral contraceptives, although data are lacking and reports are contradictory. The mechanism may be due to enzyme inhibition.

  What to do: Consider counseling women about this interaction which is unpredictable.

Conditions

Conditions in which Levonorgestrel [For emergency contraception] needs care, as documented in this source.

• Abnormal Genital Bleeding

  Major

  The use of contraceptives is contraindicated when there is an undiagnosed abnormal genital bleeding. Adequate diagnostic measures should be undertaken to rule out the presence of any malignancy.

• Breast Neoplasms

  Major

  The use of progestogens is considered by manufacturers to be contraindicated in patients with existing or suspected malignancy of the breast. Some supportive data are available for medroxyprogesterone. Specifically, medroxyprogesterone treatment may be associated with breast cancer, primarily when the drug is administered intramuscularly. A pooled analysis of two case-control studies, one from the World Health Organization and the other from New Zealand, revealed a small overall relative risk of breast cancer in women who have ever used intramuscular medroxyprogesterone acetate. The relative risk was higher in the subgroup of women who had initiated therapy within the previous 5 years. Thus, an increased risk (approximately 2-fold) is associated with intramuscular medroxyprogesterone use in the first 5 years. A more recent U.S. study also found a statistically significant increase in breast cancer risk among recent users (defined as last use within the past five years) who used depo-medroxyprogesterone acetate for 12 months or longer.

• Intracranial Hypertension

  Major

  The use of levonorgestrel contraceptive implants is contraindicated in patients with a current or past history of idiopathic intracranial hypertension (pseudotumor cerebri, benign intracranial hypertension). This disorder is most commonly seen in obese women of reproductive age and has been reported in users of levonorgestrel implants. Patients who experience symptoms of this disorder (e.g., headaches associated with changing frequency, pattern, severity or persistence; visual disturbances) while on levonorgestrel therapy should be referred to a neurologist. If the diagnosis is confirmed, the implants should be removed permanently.

• Liver Diseases

  Major

  The use of progestogens, in general, is contraindicated in patients with impaired hepatic function or liver disease. There are little or no data concerning the pharmacokinetic disposition of the different progestogens in patients with hepatic disease. However, most hormones, including progestational hormones, are known to be extensively metabolized by the liver. Medroxyprogesterone should not be used by women with significant liver disease and should be discontinued if jaundice or disturbances of liver function occur.

• Liver Neoplasms

  Major

  The use of oral contraceptives is contraindicated in patients with liver tumors. An increased risk of benign hepatic adenomas and hepatocellular carcinomas has been associated with long-term, oral estrogen- progestin contraceptive use of at least 4 years and 8 years, respectively. Although these tumors are rare and have not been reported with other types of estrogen or progestogen therapies, any preparation containing estrogens and/or progestogens should probably be avoided in patients with existing tumors of the liver. Hepatic hemangiomas and nodular hyperplasia of the liver have been reported with isolated estrogen therapy.

• Thromboembolism

  Major

  The use of levonorgestrel is considered by manufacturers to be contraindicated in patients with active thrombophlebitis or thromboembolic disorders. Some manufacturers also recommend not using progestogens in patients with a history of thromboembolic or cerebrovascular disease. While the role of progestogens in the development of thromboembolic events associated with hormonal therapy is often unclear and thought to be secondary to that of estrogens, it may not be insignificant. Levonorgestrel implants, specifically, have been associated with thrombophlebitis and superficial phlebitis, which were more common in the arm of insertion and sometimes related to trauma to the arm. There have also been post-marketing reports of stroke and myocardial infarction coincident with the use of levonorgestrel implants.

• Depressive Disorder

  Moderate

  The use of oral contraceptives has been associated with an increased incidence of depression. It is uncertain whether this effect is related to the estrogenic or the progestogenic component of the contraceptive, although excess progesterone activity is associated with depression. Patients with a history of depression receiving estrogen and/or progestogen therapy should be followed closely. The manufacturer of medroxyprogesterone recommends monitoring patients who have a history of depression and to not re- administer medroxyprogesterone if depression recurs.

• Eye Diseases

  Moderate

  Estrogens and progestogens may cause retinal thrombosis. Oral contraceptives should be discontinued if there is unexplained partial or complete loss of vision; onset of proptosis or diplopia; papilledema; or retinal vascular lesions. Therapy with these agents should be administered cautiously in patients who have preexisting ocular problems and appropriate diagnostic and therapeutic measures should be instituted. Contact lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist.

• Glucose Intolerance

  Moderate

  Impaired glucose tolerance has been observed in some patients administered oral contraceptives and appears to be related primarily to the estrogen dose. However, progestogens can increase insulin secretion and produce insulin resistance to varying degrees, depending on the agent. Patients with diabetes mellitus should be monitored more closely during therapy with estrogens and/or progestogens, and adjustments made accordingly in their antidiabetic regimen.

• Hyperlipidemias

  Moderate

  Some progestogenic agents may elevate plasma LDL levels and/or lower HDL levels, although data have been inconsistent. Patients with preexisting hyperlipidemia may require closer monitoring during progestogen therapy, and adjustments made accordingly in their lipid-lowering regimen.

• Thyroid Diseases

  Moderate

  When administering estrogen and/or progestogen therapy in patients with thyroid disorders, clinicians should be aware that these hormones may affect thyroid function tests. Changes have mostly been reported with the use of combination oral contraceptives. Specifically, thyroid-binding globulin (TBG) may be increased, resulting in elevated circulating total thyroid hormone, as measured by PBI (protein-bound iodine), T4 by column or radioimmunoassay, or T3 by radioimmunoassay. Free T3 resin uptake may be decreased. On the contrary, a decrease in TBG and, consequently, thyroxine concentration, has been reported by the manufacturers of the progestin-only (norethindrone) oral contraceptives.

• Water-Electrolyte Imbalance

  Moderate

  Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.

• Weight Gain

  Minor

  Progestogens can cause weight gain, which may be significant (as is the case with parenteral medroxyprogesterone) and undesirable in obese patients attempting to lose weight.
