Start patients with mild to moderately impaired renal function (creatinine clearance 30 to 89 mL/min evaluated by Cockcroft-Gault) with lower doses of Lithium and titrate slowly while frequently monitoring serum Lithium concentrations and for signs of Lithium toxicity [see Dosage and Administration (2.8)].

The left ventricle is thicker because systemic circulation involves a much larger blood volume than pulmonary circulation.
