Taking Alerlisin with other medicines

Taking Alerlisin with food and drinks

Alerlisin should be avoided in pregnant women. Accidental use of the medicine in pregnant women does not produce any harmful effect on the fetus. However, treatment with the medicine should be discontinued.
Alerlisin should not be taken during breastfeeding, as cetirizine is excreted in breast milk.
Driving and using machines
Clinical studies have not shown evidence that Alerlisin produces alterations in attention, decreased ability to react, and ability to drive at the recommended dose.
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 the simultaneous use of alcohol or other central nervous system depressants may further affect your attention and ability to react.
