CLARITYN ALLERGY Tablet Ref.[49992] Active ingredients: Loratadine

Clarityn Allergy Tablets should be administered with caution in patients with severe liver impairment (see section 4.2).

This medicinal product contains lactose; thus patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

The administration of Clarityn Allergy Tablets should be discontinued at least 48 hours before skin tests since antihistamines may prevent or reduce otherwise positive reactions to dermal reactivity index.

When administered concomitantly with alcohol, Clarityn Allergy Tablets have no potentiating effects as measured by psychomotor performance studies.

Potential interaction may occur with all known inhibitors of CYP3A4 or CYP2D6 resulting in elevated levels of loratadine (see Section 5.2), which may cause an increase in adverse events.

Increase in plasma concentrations of loratadine has been reported after concomitant use with ketoconazole, erythromycin, and cimetidine in controlled trials, but without clinically significant changes (including electrocardiographic).

Paediatric population

Interaction studies have only been performed in adults.

Pregnancy

A large amount of data on pregnant women (more than 1000 exposed outcomes) indicate no malformative nor feto/ neonatal toxicity of loratadine. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity (see section 5.3).

As a precautionary measure, it is preferable to avoid the use of Clarityn Allergy Tablets during pregnancy.

Breast-feeding

Loratadine is excreted in breast milk. Therefore, the use of Clarityn Allergy Tablets is not recommended in breast-feeding women.

Fertility

There are no data available on male and female fertility.

In clinical studies that assessed driving ability, no impairment was observed in patients receiving loratadine. Clarityn Allergy Tablets has no or negligible influence on the ability to drive and use machines. However, patients should be informed that very rarely some people experience drowsiness, which may affect their ability to drive or use machines.
