Warnings and precautions
Consult your doctor or pharmacist before taking Zyrtec
If you have kidney failure, consult your doctor; if necessary, you will take a lower dose. Your doctor will determine the new dose.
If you have problems urinating (such as spinal cord or prostate and bladder problems), please consult your doctor.
If you are an epileptic patient or a patient at risk of convulsions, consult your doctor.
No clinically significant interactions have been observed between alcohol (with a blood level of 0.5 per thousand (g/l), corresponding to a glass of wine) and the use of cetirizine at the recommended dose. However, there are no safety data available when taking higher doses of cetirizine and alcohol together. Therefore, as with all antihistamines, it is recommended to avoid taking Zyrtec with alcohol.
If you are going to have an allergy test, consult your doctor if you should stop taking Zyrtec a few days before the test. This medicine may affect the results of your allergy tests.
Other medicines and Zyrtec
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Taking Zyrtec with food, drinks and alcohol

Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Zyrtec should be avoided in pregnant women. Accidental use of the medicine in pregnant women does not produce any harmful effect on the fetus. However, the medicine should only be administered if necessary and after consulting a doctor.
Cetirizine passes into breast milk. It cannot be excluded that there is a risk of adverse reactions in breastfed infants. Therefore, you should not take Zyrtec during breastfeeding, unless you have consulted your doctor.
Driving and using machines
Clinical studies have not shown evidence that Zyrtec causes alterations in attention, decreased reaction capacity and ability to drive at the recommended dose.
If you intend to drive, perform potentially hazardous activities or use machinery, you should not exceed the recommended dose. You should closely observe your response to the medicine.
