Recommended Dose: Adults and adolescents 12 years and above: The daily recommended dose is 5 mg (1 tablet).
Elderly: Use caution with dose selection and start at low end of dosage range.
Renal impairment: The dosing intervals must be individualized according to renal function. Refer to the following table and adjust the dose as indicated. To use this dosing table, an estimate of the patient's creatinine clearance (CL_cr) in mL/min is needed. The CL_cr (mL/min) may be estimated from serum creatinine (mg/dL) determination using the following formula: See equation.

In pediatric patients suffering from renal impairment, the dose will have to be adjusted on an individual basis taking into account the renal clearance of the patient and his body weight. There are no specific data for children with renal impairment.
Hepatic impairment: No dose adjustment is needed in patients with solely hepatic impairment. In patients with hepatic impairment and renal impairment, adjustment of the dose is recommended (see Renal impairment previously).
Pediatric population: Children aged 6 to 12 years: The daily recommended dose is 5 mg (1 tablet).
Method of Administration: The tablet must be taken orally, swallowed whole with liquid and may be taken with or without food.
Duration of use: Intermittent allergic rhinitis (symptoms experienced for less than four days a week or for less than four weeks a year) has to be treated according to the disease and its history; it can be stopped once the symptoms have disappeared and can be restarted again when symptoms reappear. In case of persistent allergic rhinitis (symptoms experienced for more than four days a week or for more than four weeks a year), continuous therapy can be proposed to the patient during the period of exposure to allergens.
There is clinical experience with the use of levocetirizine for treatment periods of at least 6 months. In chronic urticaria and chronic allergic rhinitis, there is clinical experience of use of cetirizine (racemate) for up to one year.
