Major

ibuprofen peanut allergen extract

Applies to: NeoProfen (ibuprofen) and peanut allergen powder

GENERALLY AVOID: Concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) may pose a greater risk of more serious systemic reactions, including anaphylaxis, to immunotherapy with peanut allergen extract. The precise mechanism by which NSAIDs can induce or augment anaphylaxis has not been established, but may involve enhanced allergen absorption due to increased gastrointestinal permeability related to inhibition of prostaglandin synthesis by NSAIDs. Another proposed mechanism involves a direct impact on the IgE activation of mast cells and basophils, resulting in enhanced degranulation and release of chemical mediators such as histamine, prostaglandins, leukotrienes, and thromboxane.

MANAGEMENT: Immunotherapy with peanut allergen extract may not be appropriate in patients receiving NSAIDs due to the potential for increased risk of anaphylaxis. Alternatives to NSAIDs or temporarily withholding the immunotherapy should be considered. Otherwise, close monitoring for anaphylaxis or other allergic reactions is advised if coadministration cannot be avoided.

Drug and food interactions

Major

peanut allergen extract food

Applies to: peanut allergen powder

ADJUST DOSING INTERVAL: Coadministration of peanut allergen extract with alcohol may potentiate the risk of allergic reactions, including anaphylaxis. According to some studies, alcohol is an augmenting factor influencing immunological mechanisms that can induce more severe allergic reactions and is involved in up to 15% of cases of anaphylactic reactions. Proposed mechanisms include an increase in allergen absorption from altered permeability of the intestinal epithelial barrier, enhancing mast cell and basophil activation, and an increase in serum IgE concentrations. In addition, according to product labeling, administration of peanut allergen extract during a fasting state may potentiate the risk of allergic reactions, including anaphylaxis. The exact mechanism has not been elucidated.

MANAGEMENT: To minimize the risk of allergic reactions, including anaphylaxis, some authorities recommend alcohol not be consumed for 2 hours before, or 2 hours after taking peanut allergen extract. If alcohol cannot be avoided, withholding or decreasing peanut allergen dosage should be considered. Peanut allergen extract should also be administered with an evening meal and not within 2 hours of bedtime.

Moderate

ibuprofen food

Applies to: NeoProfen (ibuprofen)

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.

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.
