Alerzina is an antiallergic medicine.

  • chronic allergic rhinitis,
  • seasonal allergic rhinitis (hay fever),
  • allergic conjunctivitis,
  • chronic idiopathic urticaria.

2. Important information before taking Alerzina

When not to take Alerzina:

  • if you are allergic to the active substance or any of the other ingredients of this medicine (listed in section 6) or to hydroxyzine and piperazine derivatives (active substances with a similar structure, contained in other medicines);
  • if you have severe kidney disease (severe renal insufficiency with creatinine clearance less than 10 ml/min);
  • if you have hereditary galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption syndrome.

If any of these conditions apply, do not take Alerzina.
Tell your doctor and follow his advice.

Warnings and precautions

Before taking Alerzina, discuss with your doctor:

  • if you have kidney disease; a lower dose may be necessary. The dose will be determined by your doctor;
  • if you have problems with urination (e.g. spinal cord injury or prostate problems, or bladder problems);
  • if you have epilepsy or a risk of seizures.

Due to its antihistamine effect, Alerzina may affect the results of skin tests.
They should be performed after a 3-day interval following the discontinuation of the medicine.
No clinically significant interactions have been observed between alcohol (at a concentration of 0.5 g/l in the blood, corresponding to the concentration after drinking one glass of wine) and cetirizine, administered at the recommended doses. However, as with other antihistamines, it is recommended to avoid taking cetirizine with alcohol.

Alerzina and other medicines

Tell your doctor or pharmacist about all the medicines you are taking now or have taken recently, as well as about the medicines you plan to take.
Due to the profile of cetirizine, interactions with other medicines are not expected.

Alerzina with food and drink

Food does not affect the absorption of cetirizine to a significant extent.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or plan to become pregnant, consult your doctor or pharmacist before taking this medicine.
As with other medicines, Alerzina should be avoided in pregnant women.
Accidental intake of the medicine by a pregnant woman should not have a harmful effect on the fetus.
However, the medicine should only be used if necessary and after consulting a doctor.
Alerzina should not be taken during breastfeeding, as cetirizine passes into breast milk.

Driving and using machines

Clinical studies with cetirizine at the recommended dose have not shown an effect on the ability to drive vehicles, drowsiness, and psychomotor performance.
If you plan to drive a vehicle, perform potentially hazardous activities, or operate machinery after taking Alerzina, you should pay attention to your body's reaction to the medicine. Do not exceed the recommended dose.
In sensitive patients, concomitant use of cetirizine with alcohol or medicines with a sedating effect on the central nervous system may enhance the effect of the medicine on reaction time and concentration.

Alerzina contains lactose

If you have been diagnosed with an intolerance to some sugars, you should contact your doctor before taking the medicine.

3. How to take Alerzina

This medicine should always be taken exactly as described in the package leaflet or as directed by your doctor or pharmacist.

Elderly patients

If kidney function is normal, there is no need to reduce the dose.

Duration of treatment

Treatment with cetirizine without medical supervision should not exceed 10 days.
If you feel that the effect of Alerzina is too strong or too weak, consult your doctor.
