**4.2 Posology and method of administration** The dosage of CRESTOR should be individualised according to the goal of therapy and patient response. The recommended start dose is 5 or 10 mg once daily in both statin naive patients or patients switched from another HMG CoA reductase inhibitor. The choice of starting dose should take into account the individual patient’s cholesterol level and future cardiovascular risk as well as the potential risk for adverse reactions. A dose adjustment to the next dose level can be made after 4–6 weeks, if necessary (see Pharmacodynamic properties – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Increasing the dose to 40 mg should be reserved for patients with severe hypercholesterolaemia at high cardiovascular risk (in particular those with familial hypercholesterolaemia), who do not achieve their treatment goal on 20 mg and should only be initiated under close specialist supervision (see Special warnings and precautions for use of the 40 mg dose – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). The physician who elects to use CRESTOR at doses higher than 20 mg should periodically re-evaluate the long-term risk/benefit of CRESTOR for the individual patient. CRESTOR should be prescribed with caution in patients with pre-disposing factors for myopathy/rhabdomyolysis (see Special warnings and precautions for use; skeletal muscle – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). CRESTOR may be given at any time of day, with or without food. **Use in Asian population** Increased plasma concentration of rosuvastatin has been observed in Asian subjects including subjects of Japanese, Chinese, Malay and Indian ancestry (see Special warnings and precautions for use & Pharmacokinetic properties – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). Increased systemic exposure, which is considered a pre-disposing factor for myopathy, should be taken into consideration when making dose decisions for Asian patients. Initiation of CRESTOR therapy with 5 mg once daily should be considered for Asian patients. This should take into account the individual patient’s cholesterol level and future cardiovascular risk as well as the potential risk for adverse reactions. Doses exceeding 20 mg are not generally recommended and should only be considered for patients with high cardiovascular risk whose hypercholesterolaemia is not controlled with doses up to 20 mg. In rare cases where CRESTOR at doses higher than 20 mg is indicated, initiation of therapy should be under close specialist supervision. The physician who elects to use CRESTOR at doses higher than 20 mg should periodically re-evaluate the long-term risk/benefit of CRESTOR for the individual patient. **Use in children** In paediatric patients with heterozygous familial hypercholesterolemia the recommended starting dose of CRESTOR is 5 mg taken orally once daily. The CRESTOR dose should be individualized according to baseline LDL-C levels and the recommended goal of therapy. The maximum daily dose in this patient population is 10 mg. Adjustments should be made at intervals of 4 weeks or more. The safety and efficacy of CRESTOR doses greater than 20 mg have not been studied in this population. Treatment experience in paediatric patients with heterozygous familial hypercholesterolaemia is limited to 52 weeks. **Use in the elderly** No dose adjustment is necessary. **Dosage in patients with renal insufficiency** No dose adjustment is necessary in patients with mild to moderate renal impairment. For patients with severe renal impairment the use of CRESTOR is contraindicated (see Pharmacokinetic properties – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). **Dosage in patients with hepatic insufficiency** The usual dose range applies in patients with mild hepatic impairment \[Child-Pugh scores of ≤ 7\]. Increased systemic exposure to rosuvastatin has been observed in patients with moderate hepatic impairment \[Child-Pugh scores of 8 or 9\]. There is no experience in patients with severe hepatic impairment. CRESTOR is contraindicated in patients with active liver disease. (see Pharmacokinetic properties – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). **Genetic polymorphisms** Genotypes of SLCO1B1 (OATP1B1) c.521CC and ABCG2 (BCRP) c.421AA have been shown to be associated with an increase in rosuvastatin exposure (AUC) compared to SLCO1B1 c.521TT and ABCG2 c.421CC. For patients known to have the c.521CC or c.421AA genotype, a maximum once daily dose of 20 mg of CRESTOR is recommended (see Special warnings and precautions for use, Interactions and Pharmacokinetic properties – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). **Concomitant therapy** Rosuvastatin is a substrate of various transporter proteins (e.g. OATP1B1 and BCRP). The risk of myopathy (including rhabdomyolysis) is increased when CRESTOR is administered concomitantly with certain medicinal products that may increase the plasma concentration of rosuvastatin due to interactions with these transporter proteins (e.g. cyclosporin and certain protease inhibitors including combinations of ritonavir with atazanavir, lopinavir, and/or tipranavir; see Special warnings and precautions for use and Interactions – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). It is recommended that prescribers consult the relevant product information when considering administration of such products together with CRESTOR. Whenever possible, alternative medications should be considered, and if necessary, consider temporarily discontinuing CRESTOR therapy. In situations where co-administration of these medicinal products with CRESTOR is unavoidable, the benefit and the risk of concurrent treatment and CRESTOR dosing adjustments should be carefully considered (see Interactions – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_).
