Warning and precautions
Talk to your doctor or pharmacist before taking Zirtek Allergy.
If you are a patient with renal insufficiency, please ask your doctor for advice; if necessary, you will take a lower dose. The new dose will be determined by your doctor. If you have problems passing urine (like spinal cord problems or prostate or bladder problems), please ask your doctor for advice.
If you are an epileptic patient or a patient at risk of convulsions, you should ask your doctor for advice.
No clinically significant interactions have been observed between alcohol (at the blood level of 0.5 per mille (g/l) corresponding to one glass of wine) and cetirizine used at the recommended doses. However, there are no data available on the safety when higher doses of cetirizine and alcohol are taken together. Therefore, as it is the case with all antihistamines, it is recommended to avoid taking Zirtek Allergy with alcohol.
If you are scheduled for allergy testing, ask your doctor if you should stop taking Zirtek Allergy for several days before testing. This medicine may affect your allergy test results. Children
Do not give this medicine to children below the age of 6 years because the tablet formulation does not allow the necessary dose adjustments.
