Interactions between your drugs

Major

methotrexate deuruxolitinib

Applies to: methotrexate and deuruxolitinib

GENERALLY AVOID: Coadministration of deuruxolitinib with other Janus Kinase (JAK) inhibitors, biologic immunomodulators, or other potent immunosuppressants (e.g., cyclosporine) may potentiate the risk of infections, major adverse cardiovascular events (MACE), and other malignancies, including lymphomas. Serious and sometimes fatal infections including bacterial, mycobacterial (e.g., tuberculosis), fungal, viral including viral reactivation, and other opportunistic infections have been reported in patients who have received deuruxolitinib. Opportunistic infections include tuberculosis, multidermatomal herpes zoster, oral/esophageal candidiasis, and cryptococcosis. Lymphoma and other malignancies, including non-melanoma skin cancers, have also been observed with the use of deuruxolitinib and other Janus kinase (JAK) inhibitors.

MANAGEMENT: Concomitant use of deuruxolitinib with other Janus kinase (JAK) inhibitors, biologic disease-modifying antirheumatic drugs (DMARDs), or potent immunosuppressants (e.g., azathioprine, cyclosporine) is not recommended. Patients receiving deuruxolitinib should be closely monitored for the development of signs and symptoms of infection during and after treatment, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. If a patient develops a serious infection, deuruxolitinib therapy should be interrupted until the infection is controlled.

Drug and food/lifestyle interactions

Moderate

methotrexate food/lifestyle

Applies to: methotrexate

MONITOR: Limited data suggest that consumption of greater than 180 mg/day of caffeine may interfere with the efficacy of methotrexate (MTX) in patients with rheumatoid arthritis. The exact mechanism of interaction is unknown but may be related to the antagonistic effect of caffeine on adenosine receptors, as anti-inflammatory properties of MTX is thought to result from the accumulation of adenosine. In a study of 39 patients treated with MTX 7.5 mg/week (without folate supplementation) for 3 months, patients with high caffeine intake (more than 180 mg/day) experienced significantly less improvement in morning stiffness and joint pain from baseline than patients with low caffeine intake (less than 120 mg/day). There were no significant differences between the responses of patients with moderate caffeine intake (120 to 180 mg/day) and those of the other 2 groups. In an interview of 91 patients treated with MTX, 26% of patients who discontinued the drug were regular coffee drinkers compared to only 2% of those still receiving the drug. Because treatment failure was the reason for MTX discontinuation in 80% of patients who discontinued, the investigators suggested that caffeine may have interfered with MTX efficacy.

MANAGEMENT: Until further information is available, the potential for interaction should be considered in patients who consume substantial amounts of caffeine and caffeine-containing foods and are prescribed methotrexate for rheumatoid arthritis. It may be appropriate to limit caffeine intake if an interaction is suspected in cases of treatment failure.

deuruxolitinib food/lifestyle

Applies to: deuruxolitinib

MONITOR: Smoking during treatment with deuruxolitinib may increase the risk of major adverse cardiovascular events (MACE) and the risk of developing malignancies. In clinical studies of deuruxolitinib, individuals who were current or former smokers had an additional increased risk of overall malignancies. Also, deuruxolitinib may increase patients' risk of MACE, including myocardial infarction, stroke, and cardiovascular death.

MANAGEMENT: Caution is advised if deuruxolitinib is prescribed to current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and the steps to take if they occur. The manufacturer recommends discontinuing deuruxolitinib in patients that have experienced a myocardial infarction or stroke. Deuruxolitinib may be taken with or without food.

methotrexate food/lifestyle

Applies to: methotrexate

GENERALLY AVOID: Coadministration of methotrexate with other agents known to induce hepatotoxicity may potentiate the risk of liver injury. Methotrexate, especially at higher dosages or during prolonged treatment, has been associated with severe hepatotoxicity including acute hepatitis, chronic fibrosis, cirrhosis, and fatal liver failure.

MANAGEMENT: The risk of hepatic injury should be considered when methotrexate is used with other potentially 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; sulfonamides; tamoxifen; 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). Baseline and periodic monitoring of hepatic function is recommended, while liver biopsy may be warranted during long-term use of methotrexate. Patients 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, right upper quadrant pain, dark urine, pale stools, and jaundice.
