MAYZENT FILM-COATED TABLET 2MG

TABLET, FILM COATED

**4.2 Posology and method of administration** Before initiation of treatment, patients must be genotyped for CYP2C9 to determine their CYP2C9 metaboliser status (see sections 4.4, 4.5 and 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). In patients with a CYP2C9\*3\*3 genotype, Mayzent should not be used (see sections 4.3, 4.4 and 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). In patients with a CYP2C9\*2\*3 or \*1\*3 genotype, the recommended maintenance dose is 1 mg taken once daily (four tablets of 0.25 mg) (see sections 4.4 and 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). The recommended maintenance dose of Mayzent in all other CYP2C9 genotype patients is 2 mg. Mayzent is taken once daily. Posology _Treatment initiation_ Treatment has to be started with a titration pack that lasts for 5 days. Treatment starts with 0.25 mg once daily on days 1 and 2, followed by once-daily doses of 0.5 mg on day 3, 0.75 mg on day 4, and 1.25 mg on day 5, to reach the patient’s prescribed maintenance dose of Mayzent starting on day 6 (see Table 1). During the first 6 days of treatment initiation the recommended daily dose should be taken once daily in the morning with or without food.  _Missed dose(s) during treatment initiation_ During the first 6 days of treatment, if a titration dose is missed on one day, treatment needs to be re-initiated with a new titration pack. _Missed dose after day 6_ If a dose is missed, the prescribed dose should be taken at the next scheduled time; the next dose should not be doubled. _Re-initiation of maintenance therapy after treatment interruption_ If maintenance treatment is interrupted for 4 or more consecutive daily doses, Mayzent needs to be re-initiated with a new titration pack. _Special populations_ _Elderly_ Mayzent has not been studied in patients aged 65 years and above. Clinical studies included patients up to the age of 61 years. Mayzent should be used with caution in the elderly due to insufficient data on safety and efficacy (see section 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). _Renal impairment_ Based on clinical pharmacology studies, no dose adjustment is needed in patients with renal impairment (see section 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). _Hepatic impairment_ Mayzent must not be used in patients with severe hepatic impairment (Child-Pugh class C) (see section 4.3). Although no dose adjustment is needed in patients with mild or moderate hepatic impairment, caution should be exercised when initiating treatment in these patients (see sections 4.4 and 5.2 – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). _Paediatric population_ The safety and efficacy of Mayzent in children and adolescents aged 0 to 18 years have not yet been established. No data are available. Method of administration Oral use. Mayzent is taken with or without food. The film-coated tablets should be swallowed whole with water.
