PediaCare Children's 24-Hour Allergy (cetirizine) Disease Interactions

There are 2 disease interactions with PediaCare Children's 24-Hour Allergy (cetirizine):


Cetirizine (Includes PediaCare Children's 24-Hour Allergy) ↔ Alcohol

Moderate Potential Hazard, Moderate plausibility

Applies to: Acute Alcohol Intoxication

Alcohol should be avoided when using cetirizine, and some other antihistamines. Cetirizine may produce drowsiness that may be increase by the use of alcohol, sedatives and tranquilizers.


Cetirizine (Includes PediaCare Children's 24-Hour Allergy) ↔ Renal/Liver Disease

Moderate Potential Hazard, High plausibility

Applies to: Renal Dysfunction, Liver Disease

Cetirizine is eliminated primarily by the kidney but also undergoes metabolism in the liver to some extent. Patients with renal and/or liver disease may be at greater risk for adverse effects from cetirizine due to decreased drug clearance. The manufacturer recommends an initial dosage of 5 mg once daily in patients 6 years of age and older with decreased renal function (CrCl <= 30 mL/min, including those on hemodialysis) and/or impaired hepatic function. Cetirizine should preferably not be used in children less than 6 years of age with renal and/or hepatic impairment because of the difficulty in reliably administering doses smaller than 2.5 mg (1/2 teaspoonful) and a lack of pharmacokinetic and safety data in this population.
