No dosage adjustment necessary in renal impairment. Use with caution if known hepatic impairment – start on 50mg/day. Monitor patients for risk of suicidal thoughts, particularly in early treatment and following dose changes; assess metabolic parameters and weight at initiation of and throughout treatment; observe for hyperglycaemia; diabetic patients should have glucose control monitored regularly; consider dose reduction or discontinuation if symptoms of tardive dyskinesia; discontinue if neuroleptic malignant syndrome; if develop akathisia, increasing dose may be detrimental; caution in cardiovascular disease, risk factors for VTE, cerebrovascular disease, other conditions predisposing to hypotension, patients receiving concomitant CNS depressants and those at risk for sleep apnoea e.g. overweight/male, history of seizures, risk factors for neutropenia, concomitant use of medications with anti-cholinergic (muscarinic) effects, diagnosis or history of urinary retention, prostatic hypertrophy, intestinal obstruction/related conditions, increased intraocular pressure/narrow angle glaucoma, family history of QT prolongation, risk factor for stroke, suspected cardiomyopathy or myocarditis, risk of aspiration pneumonia, congenital long QT syndrome, use with medicinal products known to cause electrolyte imbalance or increase QT interval, congestive heart failure, heart hypertrophy, hypokalaemia, hypomagnesaemia, history of alcohol or drug abuse, in combination with other centrally acting medicinal products, alcohol, or with neuroleptics in the elderly. Discontinue if neutrophil count <1.0×109/L – monitor neutrophil count and for signs of infection.
Contains lactose; do not use if rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption. Do not consume grapefruit juice. Monitor if severe somnolence and consider discontinuation. Advise not to drive or operate machinery until individual susceptibility to quetiapine affecting a patient’s mental alertness is known. False positive results reported in enzyme immunoassays for methadone and tricyclic antidepressants. Recommend confirmation of questionable immunoassay screening results by an appropriate chromatographic technique. If receiving a hepatic enzyme inducer, initiation of quetiapine should only occur if benefits outweigh risks of removing hepatic enzyme inducer. Concomitant use with strong hepatic enzyme inducer could affect efficacy. Consult SmPC for dose reduction/titration or discontinuation. Advise gradual withdrawal over 1-2 weeks. Only use during pregnancy if benefits outweigh risks; use during lactation not recommended.
