This report displays the potential drug interactions for the following 2 drugs:
- peanut allergen powder
- Quzyttir (cetirizine)
Interactions between your drugs
cetirizine peanut allergen extract
Applies to: Quzyttir (cetirizine) and peanut allergen powder
MONITOR: Monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), catechol-O-methyltransferase (COMT) inhibitors, thyroid hormone, antihistamines, cardiac glycosides (e.g. digoxin) and diuretics may potentiate the response to epinephrine, including fatal consequences, in the treatment of serious systemic reactions that may occur during immunotherapy with allergenic extracts. Vasoconstricting and hypertensive effects may be potentiated by MAOIs, tricyclic antidepressants, and COMT inhibitors. Arrhythmogenic effects may be potentiated by thyroid hormones, antihistamines, cardiac glycosides and diuretics.
MANAGEMENT: Immunotherapy with allergenic extracts may not be appropriate in patients receiving MAOIs, tricyclic antidepressants, COMT inhibitors, thyroid hormone, antihistamines and cardiac glycosides as these patients may experience an exaggerated response to the usual doses of epinephrine required to reverse a systemic reaction.

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.

cetirizine food
Applies to: Quzyttir (cetirizine)
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.
