aspirin monomethyl fumarate

Applies to: Alka-Seltzer Plus Cold Formula Sparkling Original Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine) and monomethyl fumarate

MONITOR: The use of fumaric acid esters in combination with medications that can cause nephrotoxicity, including aspirin at anti-inflammatory dosages, may increase the potential for adverse renal reactions. In clinical trials in patients with multiple sclerosis treated with dimethyl fumarate, a fumaric acid ester that is converted to the active metabolite monomethyl fumarate (MMF), adverse events of proteinuria were reported at slightly higher frequencies than in patients receiving placebo. The clinical significance of these observations is unknown. Cases of Fanconi syndrome have been reported for a medicinal product containing dimethyl fumarate in combination with other fumaric acid esters. Renal toxicity, including tubular changes and/or interstitial fibrosis, has been observed in animal studies with dimethyl fumarate and diroximel fumarate. In healthy volunteers, administration of 325 mg non-enteric coated aspirin approximately 30 minutes prior to dimethyl fumarate for up to 4 weeks did not alter the pharmacokinetics of dimethyl fumarate or MMF.

MANAGEMENT: Administration of non-enteric coated aspirin (up to 325 mg) prior to fumaric acid esters such as monomethyl fumarate or its prodrugs, dimethyl fumarate or diroximel fumarate, may help reduce the incidence and/or severity of flushing. However, as there are no long-term studies evaluating the continuous use of aspirin in this situation for longer than 4 weeks, caution is advised. Assessment of renal function (e.g., serum creatinine, blood urea nitrogen, urinalysis) is recommended prior to initiating treatment with fumaric acid esters and as clinically indicated during treatment.

Drug and food interactions

Moderate

chlorpheniramine food

Applies to: Alka-Seltzer Plus Cold Formula Sparkling Original Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Moderate

aspirin food

Applies to: Alka-Seltzer Plus Cold Formula Sparkling Original Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

phenylephrine food

Applies to: Alka-Seltzer Plus Cold Formula Sparkling Original Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

aspirin food

Applies to: Alka-Seltzer Plus Cold Formula Sparkling Original Effervescent Tablets (aspirin / chlorpheniramine / phenylephrine)

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

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.
