Allertec WZF is an antiallergic medicine containing cetirizine, used in adults and children over 6 years old:

  • to relieve symptoms of the nose and eyes associated with seasonal and chronic allergic rhinitis (such as a stuffy nose, excessive watery discharge from the nose, itching of the nose, frequent sneezing, redness of the eyes, tearing, itching of the eyes);
  • to relieve symptoms of chronic idiopathic urticaria (long-lasting, severely itching hives on the skin).

2. Important information before taking Allertec WZF

When not to take Allertec WZF

If the patient has epilepsy or has had seizures, they should consult their doctor before taking the medicine.
If the patient has difficulty urinating (in conditions such as spinal cord injury or prostate enlargement), they should consult their doctor before taking the medicine.
No significant clinical interactions have been observed between alcohol (at a concentration of 0.5 per mille (g/l) in the blood, corresponding to the concentration after drinking one glass of wine) and cetirizine taken at the recommended doses. However, there is no data on the safety of concomitant use of higher doses of cetirizine and alcohol. Therefore, during treatment with Allertec WZF, the patient should avoid consuming alcohol, just like with other antihistamine medicines.
If the patient is scheduled to undergo allergy tests, they should ask their doctor if they should stop taking Allertec WZF a few days before the test. Allertec WZF may affect the results of allergy tests.
