Minor:
levonorgestrel odevixibat
Applies to: Option 2 (levonorgestrel) and odevixibat
Treatment with odevixibat may reduce the systemic absorption of lipophilic oral contraceptives. In a drug interaction study conducted in healthy female adults, coadministration of ethinyl estradiol 0.03 mg with levonorgestrel 0.15 mg and odevixibat 3 mg once daily for 6 days had no effect on the area under the plasma concentration-time curve (AUC) of levonorgestrel and decreased the AUC of ethinyl estradiol by 17%. Based on the existing data, the interaction is not expected to be clinically relevant. However, some authorities advise that the use of additional non-hormonal options such as a barrier contraceptive method should be considered in women of childbearing potential being treated with odevixibat.

Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
levonorgestrel Food/Lifestyle
Applies to: Option 2 (levonorgestrel)
Monitor
Grapefruit or 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. Because grapefruit juice inhibits primarily intestinal rather than hepatic CYP450 3A4, the magnitude of interaction is greatest for those drugs that undergo significant presystemic metabolism by CYP450 3A4 (i.e., drugs with low oral bioavailability). In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.
Management
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.

Moderate:
odevixibat Food/Lifestyle
Applies to: odevixibat
Monitor
Odevixibat may affect absorption of fat-soluble vitamins (FSV) including vitamin A, D, E, and K. In clinical studies, new onset or worsening of existing FSV deficiency was reported in 5% of placebo-treated patients, and in 16% of odevixibat-treated 120 mcg/kg/day patients. However, none of the odevixibat-treated 40 mcg/kg/day patients had new onset or worsening of existing FSV deficiency.
Management
Clinical and laboratory monitoring of FSV levels is recommended prior to and during treatment with odevixibat. Monitor INR (for vitamin K) and serum vitamins A, D, and E, and supplement if a deficiency is observed. Odevixibat should be discontinued if FSV deficiency persists or worsens, or if bleeding occurs despite adequate FSV supplementation.

Minor food/lifestyle interactions
Minor:
levonorgestrel Alcohol (Ethanol)
Applies to: Option 2 (levonorgestrel)
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. Consider counseling women about this interaction which is unpredictable.

Disease interactions
23 potential interactions Applies to: 23 conditions, including High Blood Pressure, High Cholesterol, Depression, Vitamin D Deficiency, and Migraine.
Abnormal Uterine Bleeding
Major:
Option 2
The levonorgestrel in Option 2 has a major potential interaction with Abnormal Uterine Bleeding.
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.
Asthma
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Asthma.
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.
Breast Cancer
Major:
Option 2
The levonorgestrel in Option 2 has a major potential interaction with Breast Cancer.
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.
Cerebral Vascular Disorder
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Cerebral Vascular Disorder.
The use of levonorgestrel requires careful assessment and caution in conditions of arterial disease, including stroke and myocardial infarction, and also, in patients with increased blood pressure and coagulopathies.
Cirrhosis
Major:
odevixibat
Odevixibat has a major potential interaction with Cirrhosis.
Ileal bile acid transporters, including odevixibat, are contraindicated in patients with prior or active hepatic decompensation events. The efficacy and safety of odevixibat in patients with clinically significant portal hypertension and in patients with decompensated cirrhosis have not been established. Monitor these patients more frequently and discontinue treatment if hepatic decompensation occurs.
Depression
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Depression.
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.
Diabetes Mellitus
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Diabetes Mellitus.
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. Caution and close monitoring are recommended in patients with diabetes mellitus during therapy with estrogens and/or progestogens, and adjustments made accordingly in their antidiabetic regimen.
Fluid Retention
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Fluid Retention.
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.
Heart Failure
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Heart Failure.
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.
Hepatic Tumor
Major:
Option 2
The levonorgestrel in Option 2 has a major potential interaction with Hepatic Tumor.
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.
High Blood Pressure
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with High Blood Pressure.
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.
High Cholesterol
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with High Cholesterol.
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.
History, Thrombotic/Thromboembolic Disorder
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with History, Thrombotic/Thromboembolic Disorder.
The use of levonorgestrel requires careful assessment and caution in conditions of arterial disease, including stroke and myocardial infarction, and also, in patients with increased blood pressure and coagulopathies.
Liver Disease
Major:
Option 2
The levonorgestrel in Option 2 has a major potential interaction with Liver Disease.
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.
Migraine
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Migraine.
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.
Renal Dysfunction
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Renal Dysfunction.
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.
Seizures
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Seizures.
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.
Thrombotic/Thromboembolic Disorder
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Thrombotic/Thromboembolic Disorder.
The use of levonorgestrel requires careful assessment and caution in conditions of arterial disease, including stroke and myocardial infarction, and also, in patients with increased blood pressure and coagulopathies.
Thyroid Disease
Moderate:
Option 2
The levonorgestrel in Option 2 has a moderate potential interaction with Thyroid Disease.
When administering estrogen and/or progestogen therapy in patients with thyroid disorders, clinicians should be aware that these hormones may affect thyroid function tests. Patients on thyroid replacement therapy may require higher doses of thyroid hormone and appropriate monitoring. 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.
Vitamin A Deficiency
Moderate:
odevixibat
Odevixibat has a moderate potential interaction with Vitamin A Deficiency.
Odevixibat may adversely affect absorption of fat-soluble vitamins (FSV). FSV include vitamin A, D, E, and K (measured using INR levels). Patients with progressive familial intrahepatic cholestasis and arteriohepatic dysplasia can have FSV deficiency at baseline and frequently need supplementing with FSV.
Vitamin D Deficiency
Moderate:
odevixibat
Odevixibat has a moderate potential interaction with Vitamin D Deficiency.
Odevixibat may adversely affect absorption of fat-soluble vitamins (FSV). FSV include vitamin A, D, E, and K (measured using INR levels). Patients with progressive familial intrahepatic cholestasis and arteriohepatic dysplasia can have FSV deficiency at baseline and frequently need supplementing with FSV.
Vitamin K Deficiency
Moderate:
odevixibat
Odevixibat has a moderate potential interaction with Vitamin K Deficiency.
Odevixibat may adversely affect absorption of fat-soluble vitamins (FSV). FSV include vitamin A, D, E, and K (measured using INR levels). Patients with progressive familial intrahepatic cholestasis and arteriohepatic dysplasia can have FSV deficiency at baseline and frequently need supplementing with FSV.
Weight Loss
Minor:
Option 2
The levonorgestrel in Option 2 has a minor potential interaction with Weight Loss.
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.
