Applies to: ergoloid mesylates and peanut allergen powder

GENERALLY AVOID: Alpha-adrenergic blockers and ergot alkaloids may attenuate the response to epinephrine in the treatment of serious systemic reactions, including anaphylaxis, that may occur during immunotherapy with allergenic extracts. Specifically, alpha-adrenergic blockers may antagonize the vasoconstricting and hypertensive effects of epinephrine, while ergot alkaloids can reverse the pressor effects of epinephrine.

MANAGEMENT: Immunotherapy with allergenic extracts may not be appropriate in patients receiving alpha-adrenergic blockers or ergot alkaloids, as these patients may be unresponsive to the usual doses of epinephrine required to reverse a systemic reaction.

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.

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.
