Table of contents of the leaflet

  • 1. What is Claritine Allergy and what is it used for
  • 2. Important information before taking Claritine Allergy
  • 3. How to take Claritine Allergy
  • 4. Possible side effects
  • 5. How to store Claritine Allergy
  • 6. Contents of the packaging and other information

1. What is Claritine Allergy and what is it used for

The active substance of Claritine Allergy, loratadine, is a tricyclic antihistamine, a selective antagonist of peripheral histamine H receptors.
Claritine Allergy is an anti-allergic medicine that does not cause drowsiness. Claritine Allergy is indicated for the treatment of symptoms of allergic rhinitis (such as: sneezing, runny nose, and itching, itching and burning of the eyes) and chronic idiopathic urticaria.

2. Important information before taking Claritine Allergy

When not to take Claritine Allergy:

  • if the patient is allergic to the active substance or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Before starting to take Claritine Allergy, the patient should discuss it with their doctor or pharmacist:

  • if the patient has severe liver impairment (see section 3. How to take Claritine Allergy).

Treatment with loratadine without a doctor's recommendation should not exceed 10 days.

Skin tests:

The patient should stop taking Claritine Allergy about 48 hours before scheduled skin tests, as antihistamines may cause false-negative results (may reduce or completely inhibit the skin reaction that would normally be positive).

Claritine Allergy and other medicines

Side effects may be exacerbated when taking Claritine Allergy with medicines that affect the activity of certain enzymes responsible for drug metabolism in the liver. However, clinical trials have not shown an increase in side effects when loratadine is taken with medicines that affect the activity of these enzymes. Concurrent administration of loratadine with ketoconazole, erythromycin, or cimetidine increases the plasma concentration of loratadine, but without clinical consequences. Concurrent use of loratadine with medicines that affect liver metabolism should be done under medical supervision.
The patient should inform their doctor or pharmacist about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take. This includes medicines available without a prescription.

Taking Claritine Allergy with food, drink, and alcohol

The medicine can be taken independently of meals.
The medicine taken simultaneously with alcohol does not enhance its effects to a degree that can be assessed by psychomotor tests.

Pregnancy, breastfeeding, and fertility

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine.
As a precaution, it is recommended to avoid taking Claritine Allergy during pregnancy.
Loratadine passes into breast milk, so it is not recommended to take the medicine during breastfeeding.
There is no data on fertility in men and women.

Driving and using machines

In clinical trials, loratadine did not affect or had a negligible effect on the ability to drive and use machines. In some individuals, very rare cases of drowsiness occurred, which could impair the ability to drive and use machines.

Claritine Allergy contains lactose monohydrate

The medicine contains lactose monohydrate as an excipient. If the patient has previously been diagnosed with intolerance to some sugars, they should consult their doctor before taking the medicine.

3. How to take Claritine Allergy

This medicine should always be taken exactly as described in the patient leaflet or as advised by
the doctor or pharmacist. In case of doubt, the patient should consult their doctor or pharmacist.
The dividing line on the tablet is only to facilitate breaking it for easier swallowing.
Recommended dose
Adults and children over 12 years old:
1 tablet (10 mg) once a day. The medicine can be taken independently of meals.
Children from 6 to 12 years old:
Body weight over 30 kg: 1 tablet (10 mg) once a day.
It is not recommended to take tablets (10 mg) in children with a body weight of less than 30 kg.
Patient with liver function disorders:
In patients with severe liver impairment, a lower initial dose should be used, as the clearance of loratadine may be reduced in these individuals. In such cases, adults and children with a body weight over 30 kg should be given 1 tablet (10 mg loratadine) every other day.
There is no need to change the dose in elderly patients and patients with renal impairment.
In case of doubts about dosing, the patient should consult their doctor.
If the patient feels that the effect of Claritine Allergy is too strong or too weak, they should consult their doctor.

Taking a higher dose of Claritine Allergy than recommended

In case of taking a higher dose of Claritine Allergy than recommended, the patient should immediately consult their doctor or pharmacist.
After an overdose of loratadine, the following have been observed: drowsiness, increased heart rate, and headache.
In case of overdose, symptomatic and supportive treatment should be applied immediately and continued as long as necessary. Activated charcoal can be given as a water suspension. Gastric lavage can also be performed. Loratadine cannot be eliminated from the body by hemodialysis, and it is not known whether it can be eliminated by peritoneal dialysis.
After providing assistance, the patient should continue to be monitored.
There is no data indicating that loratadine causes abuse or dependence.

Missing a dose of Claritine Allergy

A double dose should not be taken to make up for a missed dose.
In case of any further doubts about taking this medicine, the patient should consult their doctor or pharmacist.

4. Possible side effects

Like all medicines, Claritine Allergy can cause side effects, although not everybody gets them.

  • in children from 2 to 12 years old - headache, nervousness, and fatigue.
  • in adults and adolescents - drowsiness.
