| HMG-CoA reductase inhibitors, including LESCOL, are unlikely to be of benefit in patients with rare homozygous familial hypercholesterolaemia.As with other lipid-lowering drugs, it is recommended that liver function tests be performed before the initiation of treatment and at 12 weeks following initiation of treatment or elevation in dose and periodically thereafter in all patients. Should an increase in aspartate aminotransferase (AST) or alanine aminotransferase (ALT) exceed 3 times the upper limit of normal and persist, therapy should be discontinued. In very rare cases, possibly drug-related hepatitis was observed that resolved upon discontinuation of treatment.Caution should be exercised when LESCOL is administered to patients with a history of liver disease or heavy alcohol ingestion.Since fluvastatin is eliminated primarily via the biliary route and is subject to significant pre-systemic metabolism, the potential exists for drug accumulation in patients with hepatic insufficiency.The use of fluvastatin in combination with glibenclamide should be avoided whenever possible (see Section 4.5 Interactions with other medicaments and other forms of interaction). Skeletal muscle: With LESCOL, myopathy has rarely been reported, whereas myositis and rhabdomyolysis have been reported very rarely. In patients with unexplained diffuse myalgias, muscle tenderness or muscle weakness, and/or marked elevation of creatine kinase (CK) values, myopathy, myositis or rhabdomyolysis have to be considered. Patients should therefore be advised to report promptly unexplained muscle pain, muscle tenderness or muscle weakness, particularly if accompanied by malaise or fever. Creatine kinase measurement: There is no current evidence to require routine monitoring of plasma total creatine kinase or other muscle enzyme levels in asymptomatic patients on statins. If creatine kinase has to be measured it should not be done following strenuous exercise or in the presence of any plausible alternative cause of CK-increase as this makes the value interpretation difficult. Before the treatment: As with all other statins physicians should prescribe fluvastatin with caution in patients with pre-disposing factors for rhabdomyolysis and its complications. A creatine kinase level should be measured before starting fluvastatin treatment in the following situations:• Renal impairment • Hypothyroidism • Personal or familial history of hereditary muscular disorders • Previous history of muscular toxicity with a statin or fibrate • Alcohol abuse• In elderly (age> 70 years), the necessity of such measurement should be considered, according to the presence of other predisposing factors for rhabdomyolysis.In such situations, the risk of treatment should be considered in relation to the possible benefit and clinical monitoring is recommended. If CK-levels are significantly elevated at baseline (> 5xULN), levels should be re-measured within 5 to 7 days later to confirm the results. If CK-levels are still significantly elevated (> 5xULN) at baseline, treatment should not be started.Whilst on treatment: If muscular symptoms like pain, weakness or cramps occur in patients receiving fluvastatin, their CK-levels should be measured. Treatment should be stopped, if these levels are found to be significantly elevated (> 5xULN).If muscular symptoms are severe and cause daily discomfort, even if CK-levels are elevated to 5 x ULN, treatment discontinuation should be considered.Should the symptoms resolve and CK-levels return to normal, then re-introduction of fluvastatin or another statin may be considered at the lowest dose and under close monitoring.The risk of myopathy is known to be increased in patients receiving immunosuppressive drugs (including ciclosporin), fibrates, nicotinic acid or erythromycin together with other HMG-CoA reductase inhibitors. Minimal data exist to support the efficacy or safety of LESCOL in combination with nicotinic acid, its derivatives, fibrates or ciclosporin. Isolated cases of myopathy have been reported post-marketing for concomitant administration of fluvastatin with colchicine. LESCOL should be used with caution in patients receiving such concomitant medication (see Section 4.5).Interstitial lung disease Exceptional cases of interstitial lung disease have been reported with some statins, especially with long term therapy (see section 4.8). Presenting features can include dyspnoea, non-productive cough and deterioration in general health (fatigue, weight loss and fever). If it is suspected a patient has developed interstitial lung disease, statin therapy should be discontinued.Children and adolescents with heterozygous familial hypercholesterolemia In patients aged <18 years, efficacy and safety have not been studied for treatment periods longer than two years. No data are available about the physical, intellectual and sexual maturation for prolonged treatment period. The long-term efficacy of Lescol therapy in childhood to reduce morbidity and mortality in adulthood has not been established. (see Section 5.1).Fluvastatin has only been investigated in children of 9 years and older with heterozygous familial hypercholesterolaemia (for details see section 5.1). In the case of pre-pubertal children, as experience is very limited in this group, the potential risks and benefits should be carefully evaluated before the initiation of treatment. | |
