1. What Alerzina is and what it is used for

The active substance in Alerzina is cetirizine dihydrochloride.
Alerzina is an antiallergic medicinal product.
Alerzina is indicated in adults and children aged 6 years and older:

  • for relief of nasal and ocular symptoms associated with seasonal and perennial allergic rhinitis,
  • for relief of symptoms of urticaria.

2. Important information before using Alerzina

When not to use Alerzina:

  • if the patient is allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6), hydroxyzine, or piperazine derivatives (active substances with a similar structure found in other medicines);
  • if the patient has end-stage renal failure (severe kidney failure requiring dialysis);
  • if the patient has hereditary galactose intolerance, lactase deficiency, or glucose-galactose malabsorption syndrome.

If any of the above conditions apply, Alerzina must not be used. The patient should inform their doctor and follow the doctor's advice.

Warnings and precautions

Before starting treatment with Alerzina, discuss the following with a doctor:

  • if the patient has kidney impairment; a lower dose may be required. The doctor will determine the appropriate dosage;
  • if the patient has difficulty urinating (e.g. due to spinal cord, prostate, or bladder problems);
  • if the patient has epilepsy or is at risk of seizures.

Due to its antihistamine (antiallergic) effect, Alerzina may affect the results of skin tests. The medicine should be discontinued at least 3 days before such tests are performed.

Alerzina and alcohol

No clinically significant interactions have been observed between alcohol (at a blood concentration of 0.5 g/l, equivalent to the level after drinking one glass of wine) and ceterizine when used at recommended doses. However, there is no safety data available regarding concomitant use of higher doses of ceterizine and alcohol. Therefore, as with other antihistamine medicines, it is recommended to avoid taking ceterizine together with alcohol.

Children

This medicine should not be given to children under 6 years of age, as the tablet form does not allow for appropriate dose adjustment.

Alerzina and other medicines

Inform your doctor or pharmacist about all medicines the patient is currently taking or has recently taken, as well as any medicines planned for future use.

Alerzina with food and drink

Food does not significantly affect the extent of ceterizine absorption.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to become pregnant, she should consult a doctor or pharmacist before using this medicine.

As with other medicines, the use of Alerzina in pregnant women should be avoided. Accidental use during pregnancy is not expected to have harmful effects on the fetus. However, the medicine should only be used if clearly necessary and after consultation with a doctor.

Alerzina should not be used during breastfeeding, as ceterizine passes into breast milk.

Driving and operating machinery

Clinical studies using ceterizine at the recommended dose have not shown a significant effect on the ability to drive, drowsiness, or psycho-motor performance.

If the patient intends to drive, perform potentially hazardous activities, or operate machinery after taking Alerzina, they should pay attention to their individual response to the medicine. The recommended dose should not be exceeded.

In sensitive individuals, concomitant use of ceterizine with alcohol or medicines with central nervous system depressant effects may increase the medicine's effect on reaction time and concentration.

Alerzina contains lactose

If the patient has previously been diagnosed with an intolerance to certain sugars, they should consult their doctor before taking this medicine.
