Interactions between your drugs

Moderate

methotrexate influenza virus vaccine, inactivated

Applies to: Xatmep (methotrexate) and Fluzone Preservative-Free Quadrivalent (influenza virus vaccine, inactivated)

MONITOR: The administration of inactivated, killed, or otherwise noninfectious vaccines to immunosuppressed patients is generally safe but may be associated with a diminished or suboptimal immunologic response due to antibody inhibition. Such patients may include those who have recently received or are receiving immunosuppressive agents, antilymphocyte globulins, alkylating agents, antimetabolites, radiation, some antirheumatic agents, high dosages of corticosteroids or adrenocorticotropic agents (e.g., greater than or equal to 2 mg/kg/day or 20 mg/day of prednisone or equivalent for 14 consecutive days or more), or long-term topical or inhaled corticosteroids.

MANAGEMENT: In general, the U.S. Department of Public Health Advisory Committee on Immunization Practices (ACIP) recommends that inactivated or killed vaccines be administered to non-HIV immunosuppressed patients according to the same guidelines as for healthy patients. However, higher dosages, more frequent boosters, and/or serological testing may be required in some cases. Local guidelines and prescribing information for individual vaccines should be consulted. For Haemophilus influenzae b vaccine, some experts recommend that it be administered at least 2 weeks before starting or 3 months after discontinuing chemotherapy when used in patients with Hodgkin's disease. For rabies vaccine, some authorities suggest that immunosuppressive agents should generally be avoided during postexposure therapy except when absolutely necessary for the treatment of other conditions. For SARS-CoV-2 (COVID-19) vaccines, vaccination should generally be completed at least 2 weeks before initiation or resumption of immunosuppressive therapies; however, decisions to delay or temporarily withhold immunosuppressive therapy to complete COVID-19 vaccination should consider the individual's risks relative to their underlying condition. Some authorities recommend administering the COVID-19 vaccine approximately 4 weeks prior to the next scheduled therapy for those on B-cell-depleting therapies on a continuing basis. Additional shots, boosters, and even revaccination may be appropriate depending on age, prior COVID-19 vaccine formulation(s) received, current or planned immunosuppressive therapy, and other factors in individuals with moderate to severe immune compromise due to medical conditions or immunosuppressive medications or treatments (e.g., solid organ transplant recipients on immunosuppressive therapy; patients on active treatment for solid tumor and hematologic malignancies). Vaccines may generally be administered to patients receiving corticosteroids as replacement therapy (e.g., for Addison's disease).

Drug and food interactions

Moderate

methotrexate food

Applies to: Xatmep (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.

Moderate

methotrexate food

Applies to: Xatmep (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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
