Interactions between your drugs

Moderate

estradiol levobupivacaine

Applies to: elagolix / estradiol / norethindrone and levobupivacaine

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inhibitors of CYP450 1A2 and/or 3A4 may increase the plasma concentrations of levobupivacaine, which is primarily metabolized by these isoenzymes. Although no clinical studies have been conducted, the possibility of prolonged and/or increased pharmacologic effects of levobupivacaine should be considered.

MANAGEMENT: Caution may be advisable if levobupivacaine is administered to patients receiving inhibitors of CYP450 1A2 (e.g., quinolones, deferasirox, mexiletine, propafenone, ticlopidine, zileuton) or CYP450 3A4 (e.g., azole antifungals, macrolide antibiotics, protease inhibitors, kinase inhibitors, aprepitant, conivaptan, cyclosporine, delavirdine, diltiazem, nefazodone, verapamil). Particular caution and dosage adjustment of levobupivacaine may be warranted during concomitant use of both a CYP450 1A2 inhibitor and a CYP450 3A4 inhibitor, or a drug that inhibits both isoenzymes (e.g., fluvoxamine). Patients should be monitored for early signs and symptoms of central nervous system toxicity such as dizziness, drowsiness, lightheadedness, anxiety, restlessness, incoherent speech, tremors, twitching, numbness and tingling of the mouth and lips, metallic taste, tinnitus, and blurred vision, as well as more serious reactions including convulsions, hypotension, arrhythmias, and cardiorespiratory depression.

Moderate

estradiol elagolix

Applies to: elagolix / estradiol / norethindrone and elagolix / estradiol / norethindrone

Estradiol and other estrogen-containing medications may reduce the effectiveness of elagolix in treating your condition. If you require contraception, it is recommended that you use a non-hormonal form of contraception during treatment with elagolix and for one week after its discontinuation. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

norethindrone elagolix

Applies to: elagolix / estradiol / norethindrone and elagolix / estradiol / norethindrone

Elagolix may reduce the blood levels and effects of norethindrone. If you are using low-dose oral contraceptives, you may have an increased risk of breakthrough bleeding and unintended pregnancy. You should discuss the use of alternative or additional methods of birth control with your healthcare provider. If you take hormone replacement for menopause, notify your doctor if your medication is no longer controlling your symptoms or you experience abnormal bleeding. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
