- peanut allergen powder
- Toradol IM (ketorolac)
Interactions between your drugs
ketorolac peanut allergen extract
Applies to: Toradol IM (ketorolac) 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
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.

ketorolac food
Applies to: Toradol IM (ketorolac)
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.
