1. What is Alerlisin and what is it used for
The active substance of Alerlisin is cetirizine dihydrochloride.
Alerlisin is an antiallergic medicine.
Alerlisin is indicated in adults and children from 2 years of age, for:
- relief of nasal and ocular symptoms associated with seasonal and perennial allergic rhinitis.
- relief of chronic urticaria (chronic idiopathic urticaria).
2. What you need to know before you take Alerlisin
Do not take Alerlisin
- if you have severe kidney disease (severe renal insufficiency with creatinine clearance below 10 ml/min);
- if you are allergic to the active substance, to any of the other ingredients of this medicine (listed in section 6), to hydroxyzine or to any piperazine derivative (closely related active substances of other medicines).
Do not take Alerlisin 1 mg/ml oral solution if:
- you have rare hereditary problems of fructose intolerance.
Warnings and precautions
Consult your doctor or pharmacist before taking Alerlisin
- if you have kidney problems, consult your doctor; if necessary, you will take a lower dose. Your doctor will determine the new dose.
- if you are an epileptic patient or a patient at risk of convulsions, consult your doctor.
No clinically significant interactions have been observed between alcohol (with a blood level of 0.5 per thousand) and the use of cetirizine at normal doses. However, as with all antihistamines, it is recommended to avoid consuming alcohol during treatment.
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.
Children
The use of the medicine is not recommended in children under 2 years of age.
Taking Alerlisin with food and drinks
Food does not affect the degree of 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.
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.
Alerlisin contains sorbitol (E-420), methyl parahydroxybenzoate (E-218) and propyl parahydroxybenzoate (E-216), propylene glycol (E-1520) and sodium
This medicine contains 450 mg of sorbitol (E-420) in each ml.
Sorbitol is a source of fructose. If your doctor has told you that you (or your child) have an intolerance to certain sugars, or have been diagnosed with hereditary fructose intolerance (HFI), a rare genetic disorder, in which the patient cannot break down fructose, consult your doctor before taking this medicine.
Sorbitol may cause gastrointestinal upset and a mild laxative effect.
It can cause allergic reactions (possibly delayed) because it contains methyl parahydroxybenzoate (E-218) and propyl parahydroxybenzoate (E-216).
This medicine contains 50 mg of propylene glycol (E-1520) in each ml.
This medicine contains less than 23 mg of sodium (1 mmol) per ml; this is, essentially “sodium-free”.
