Aubagio and Midol PM

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Teriflunomide may cause liver problems, and using it with other medications that can also affect the liver such as acetaminophen may increase that risk. Because teriflunomide can stay in your blood for a prolonged period after the last dose, interactions with other drugs may occur for some time even after you have stopped taking it. You should avoid or limit the use of alcohol while being treated with these medications. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark colored urine, light colored stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. Talk to your doctor or pharmacist if you have any questions or concerns. 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.

MONITOR CLOSELY: The recent, concomitant, or subsequent use (without the recommended leflunomide washout period or procedure) of other agents known to induce hepatotoxicity may potentiate the risk of liver injury associated with leflunomide. The risk is thought to extend to teriflunomide, its principal active metabolite, because recommended dosages of both result in a similar range of plasma concentrations of teriflunomide. Elevated liver transaminases, hepatitis, jaundice/cholestasis, hepatic failure, and acute hepatic necrosis have been reported with the use of leflunomide. Liver enzyme elevations were generally mild (2 times the upper limit of normal or less) and resolved while continuing treatment. Marked elevations (greater than 3-fold ULN) occurred infrequently and reversed with dose reduction or discontinuation of treatment in most cases. However, fatalities associated with severe liver injury have also been reported rarely. A 2009 review of leflunomide adverse event reports by the FDA identified 49 cases of severe liver injury, including 14 cases of fatal liver failure, between August 2002 and May 2009. An additional five patients required a liver transplant and nine patients experienced a life-threatening event. In this review, concomitant use of other hepatotoxic drugs and preexisting liver disease were associated with the greatest risk for liver injury during leflunomide treatment. Specifically, 46 of the 49 patients were also taking other medications that have been associated with liver injury including methotrexate, TNF-alfa blockers, hydroxychloroquine, acetaminophen, nonsteroidal anti-inflammatory drugs and statins, and 14 patients had preexisting liver disease such as active or chronic hepatitis and/or a history of alcohol abuse. The estimated duration of leflunomide exposure before onset of severe liver injury ranged from 9 days to 6 years, with the majority occurring within the first 6 to 12 months of treatment.

MANAGEMENT: Caution is advised if leflunomide or teriflunomide must be used in patients who are currently receiving or have recently received treatment with other hepatotoxic agents (e.g., acetaminophen; alcohol; androgens and anabolic steroids; antituberculous agents; azole antifungal agents; ACE inhibitors; cyclosporine (high dosages); disulfiram; endothelin receptor antagonists; interferons; ketolide and macrolide antibiotics; kinase inhibitors; minocycline; nonsteroidal anti-inflammatory agents; nucleoside reverse transcriptase inhibitors; proteasome inhibitors; retinoids; thiazolidinediones; tolvaptan; vincristine; zileuton; anticonvulsants such as carbamazepine, hydantoins, felbamate, and valproic acid; lipid-lowering medications such as fenofibrate, lomitapide, mipomersen, niacin, and statins; herbals and nutritional supplements such as black cohosh, chaparral, comfrey, DHEA, kava, pennyroyal oil, and red yeast rice), and vice versa. Liver enzymes and bilirubin should be measured prior to initiation of leflunomide/teriflunomide therapy and at least monthly for the first six months of treatment and every 6 to 8 weeks thereafter. Patients with preexisting liver disease or elevated baseline liver enzymes (i.e., ALT greater than two times ULN) should not receive leflunomide or teriflunomide. Patients who develop elevated serum ALT greater than three times ULN while receiving these medications should discontinue treatment and be given washout procedures with cholestyramine or activated charcoal to accelerate elimination of leflunomide's active metabolite from plasma, which otherwise may take up to two years. Follow-up monitoring should be conducted at least weekly until the ALT value is within normal range, and washout procedures repeated as necessary. All patients treated with leflunomide or teriflunomide should be advised to seek medical attention if they experience potential signs and symptoms of hepatotoxicity such as fever, rash, itching, anorexia, nausea, vomiting, fatigue, malaise, right upper quadrant pain, dark urine, pale stools, and jaundice.
