Children

The use of the medicine is not recommended in children under 2 years of age.

Taking Alerlisin with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Due to the profile of cetirizine, no interactions with other medicines are expected.

Taking Alerlisin with food and drinks

Food does not significantly affect the absorption of cetirizine.

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.

The use of Alerlisin should be avoided in pregnant women. Accidental use of the medicine in pregnant women should not produce any harmful effect on the fetus. However, administration of the medicine should be discontinued.

You should not take Alerlisin during breastfeeding, as cetirizine is excreted in breast milk.

If you intend to drive, perform potentially hazardous activities or use machinery, do not exceed the recommended dose. You should closely observe your response to the medicine.

If you are a sensitive patient, you may find that concurrent use of alcohol or other central nervous system depressants may further affect your attention and ability to react.
