Renal Dose Adjustments
CrCl less than 30 mL/min: 5 mg orally or chewed once a day.
Use of Zyrtec solution is not recommended in children under 6 years of age with renal impairment due to the difficulty in reliably administering doses less than 2.5 mg (1/2 teaspoonful) and the lack of pharmacokinetic and safety information of Zyrtec solution in such patients.
Liver Dose Adjustments
5 mg orally or chewed once a day
Use of Zyrtec solution is not recommended in children under 6 years of age with hepatic impairment due to the difficulty in reliably administering doses less than 2.5 mg (1/2 teaspoonful) and the lack of pharmacokinetic and safety information of Zyrtec solution in such patients.
Precautions
In clinical trials, the occurrence of somnolence has been reported. Due caution should therefore be exercised when driving a car or operating potential dangerous machinery. Concurrent use of alcohol or other CNS depressants should be avoided because additional reductions in alertness and additional impairment of CNS performance may occur.
Dialysis
Zyrtec solution is not significantly removed by hemodialysis, thus supplementary dosing is not required following hemodialysis. The recommended dosage for patients on hemodialysis is 5 mg orally or chewed once a day.

What other drugs will affect Zyrtec solution?
Tell your doctor if you regularly use other medicines that make you sleepy (such as other cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by Zyrtec solution.
This list is not complete and other drugs may interact with Zyrtec solution. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
Zyrtec solution interactions
Tablet: Concurrent use with alcohol may potentiate the CNS depressant effects of Zyrtec solution; maprotiline or tricyclic antidepressants may potentiate the anticholinergic effects of either these medications or Zyrtec solution.
Monoamine oxidase (MAO) inhibitors are not recommended because the use may prolong and intensify the anticholinergic and CNS depressant effects of Zyrtec solution.
Concurrent use with ototoxic medications may mask the symptoms of ototoxicity eg, tinnitus, dizziness or vertigo; photosensitizing medications may cause additive photosensitizing effects.
Syrup: No interaction is observed for Zyrtec solution with pseudoephedrine, cimetidine, ketoconazole, erythromycin and azithromycin. Small decrease in Zyrtec solution clearance is observed when theophylline (400 mg once daily) is taken with Zyrtec solution. However, disposition of theophylline was not altered by concomitant Zyrtec solution administration. Concomitant administration of Zyrtec solution and macrolides or ketoconazole has never resulted clinically relevant EGG changes. Extent of exposure to Zyrtec solution was increased by 40% when ritonavir is taken with Zyrtec solution. Disposition of ritonavir was slightly altered further to concomitant Zyrtec solution administration.
