Drug Interactions between amitriptyline and Oriahnn
This report displays the potential drug interactions for the following 2 drugs:
- amitriptyline
- Oriahnn (elagolix/estradiol/norethindrone)
Interactions between your drugs
estradiol elagolix
Applies to: Oriahnn (elagolix / estradiol / norethindrone) and Oriahnn (elagolix / estradiol / norethindrone)
GENERALLY AVOID: Since endometriosis is fueled by estrogen, coadministration with estrogen-containing medications including combination oral contraceptive pills is expected to reduce the efficacy of elagolix. The effect of progestin-only contraceptives is unknown. Elagolix is a gonadotropin-releasing hormone (GnRH) receptor antagonist that inhibits endogenous GnRH signaling by binding competitively to GnRH receptors in the pituitary gland. Administration of elagolix results in dose-dependent suppression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), leading to decreased levels of the ovarian sex hormones, estradiol and progesterone.
MANAGEMENT: Women requiring contraception should be advised to use non-hormonal forms of contraception during treatment with elagolix and for one week after its discontinuation.

norethindrone elagolix
Applies to: Oriahnn (elagolix / estradiol / norethindrone) and Oriahnn (elagolix / estradiol / norethindrone)
ADDITIONAL CONTRACEPTION RECOMMENDED: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of estrogens and progestins. Estrogens have been shown in in vitro and in vivo studies to be partially metabolized by CYP450 3A4, and other steroids including progestins are also believed to undergo metabolism by this isoenzyme. The interaction has been reported primarily with oral contraceptives. There have been case reports of menstrual breakthrough bleeding or unwanted pregnancy in women receiving low-dose oral contraceptives following the addition of known CYP450 3A4 inducers such as carbamazepine, phenobarbital, phenytoin, rifampin, and St. John's wort. Inadequate response to estrogen replacement therapy has also been reported in a patient treated with phenytoin. Aminoglutethimide, a CYP450 3A4 inducer, has been shown to decrease medroxyprogesterone and megestrol serum levels by 74% in six patients stabilized on their progestin regimen.
MANAGEMENT: Pharmacologic response to estrogens and progestins should be monitored more closely whenever a CYP450 3A4 inducer is added to or withdrawn from therapy, and the hormone dosage adjusted as necessary. For patients receiving hormonal contraceptives, additional or alternative non-hormonal birth control may be advisable during concomitant therapy with CYP450 3A4 inducers. Additional or alternative non-hormonal birth control may be recommended beyond discontinuation of the CYP450 3A4 inducer(s). Individual product labeling should be consulted for specific time frames. Intrauterine systems are unlikely to be significantly affected because of their local action. Input from a gynecologist or similar expert on adequate contraception, including emergency contraception, should be sought as needed. Patients should be advised to notify their physician if they experience inadequate control of symptoms associated with estrogen deficiency (e.g., nocturnal sweating, vasomotor disturbances, atrophic vaginitis) or changes in the uterine bleeding profile.

amitriptyline estradiol
Applies to: amitriptyline and Oriahnn (elagolix / estradiol / norethindrone)
The effects of tricyclic antidepressants (TCAs) may be altered in women receiving estrogen-containing therapy. Simultaneous TCA toxicity and reduced effects have been reported. Akathisia has also been reported in some women taking this combination. The mechanism of interaction is unknown but may be related to increased TCA bioavailability or inhibition of hepatic TCA metabolism. The clinical significance of this interaction has not been established. Monitoring for altered effects may be advisable during concomitant therapy. Dose adjustments of the TCA may be required if an interaction is suspected.

Drug and food interactions
norethindrone food
Applies to: Oriahnn (elagolix / estradiol / norethindrone)
MONITOR: 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.

amitriptyline food
Applies to: amitriptyline
GENERALLY AVOID: Concomitant use of ethanol and a tricyclic antidepressant (TCA) may result altered TCA plasma levels and efficacy, and additive impairment of motor skills, especially driving skills. Acute ethanol ingestion may inhibit TCA metabolism, while chronic ingestion of large amounts of ethanol may induce hepatic TCA metabolism.
MANAGEMENT: Patients should be advised to avoid alcohol during TCA therapy. Alcoholics who have undergone detoxification should be monitored for decreased TCA efficacy. Dosage adjustments may be required.

estradiol food
Applies to: Oriahnn (elagolix / estradiol / norethindrone)
Coadministration with grapefruit juice may increase the bioavailability of oral estrogens. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall induced by certain compounds present in grapefruits. In a small, randomized, crossover study, the administration of ethinyl estradiol with grapefruit juice (compared to herbal tea) increased peak plasma drug concentration (Cmax) by 37% and area under the concentration-time curve (AUC) by 28%. Based on these findings, grapefruit juice is unlikely to affect the overall safety profile of ethinyl estradiol. However, as with other drug interactions involving grapefruit juice, the pharmacokinetic alterations are subject to a high degree of interpatient variability. Also, the effect on other estrogens has not been studied.

norethindrone food
Applies to: Oriahnn (elagolix / estradiol / norethindrone)
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.
