Interactions between your drugs

Moderate

anakinra diroximel fumarate

Applies to: Kineret (anakinra) and diroximel fumarate

GENERALLY AVOID: The use of interleukin-1 blockers with other immunosuppressive or myelosuppressive agents may increase the risk of infections. Interleukin-1 blockade alone may cause neutropenia and serious infections, and the risk may be increased in the presence of other immunosuppressive therapy. Agents that may be significantly myelo- or immunosuppressive include antineoplastic agents, radiation, zidovudine, linezolid, some antirheumatic agents, high dosages of corticosteroids or adrenocorticotropic agents (greater than 10 mg/day to 1 mg/kg/day, whichever is less, of prednisone or equivalent for more than 2 weeks), and long-term topical or inhaled corticosteroids.

MANAGEMENT: The safety and efficacy of interleukin-1 blockers in immunosuppressed patients have not been established. Until more information is available, interleukin-1 blockers should preferably not be administered to immunosuppressed patients, or they should be prescribed with extreme caution. Interleukin-1 blockers should be discontinued if neutropenia or serious infection occurs.

Drug and food interactions

Moderate

diroximel fumarate food

Applies to: diroximel fumarate

GENERALLY AVOID: Food does not significantly affect the oral bioavailability of diroximel fumarate. Administration of diroximel fumarate with a high-fat, high-calorie (900 to 1000 calories; 50% from fat) meal did not affect the systemic exposure (AUC) of its active metabolite, monomethyl fumarate (MMF), but decreased its peak plasma concentration (Cmax) by 44% and prolonged the time to reach peak concentration (Tmax) from 2.5 to 7.0 hours relative to administration in the fasted state. In comparison, administration of diroximel fumarate with low-fat, low-calorie (350 to 400 calories; 10 to 15 g fat) and medium-fat, medium-calorie (650 to 700 calories; 25 to 30 g fat) meals decreased the MMF Cmax by approximately 12% and 25%, respectively, while also leaving the AUC unaffected.

GENERALLY AVOID: Coadministration of diroximel fumarate with ethanol may reduce the plasma concentrations of monomethyl fumarate (MMF). The mechanism has not been reported. Following coadministration with 240 mL of 5% v/v and 40% v/v ethanol, the mean Cmax of MMF was reduced by 9% and 21%, respectively, relative to coadministration with water. The AUC of MMF was not significantly altered, indicating that ethanol did not induce dose dumping.

MANAGEMENT: Diroximel fumarate may be taken with or without food; however, high-fat, high-calorie meals or snacks should be avoided. The manufacturer recommends meals or snacks containing no more than 700 calories and no more than 30 grams of fat. Taking diroximel fumarate with food may improve tolerability for patients experiencing flushing or gastrointestinal adverse reactions. The manufacturer also recommends avoiding concomitant use of diroximel fumarate with ethanol.

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.
