The ratio of weight-related lithium dose to plasma level showed a 36% decline with age (0.58, 0.46 and 0.37 1/kg, P less than 0.0001, analysis of variance). Elderly, over 65 years: initially 200mg daily as a single dose at night.

All studies on lithium toxicity in elderly (aged ≥ 65 years) where the dose of lithium or serum lithium level was clearly described, were included. previous medical history of lithium therapy has been obtained.

Applies to the following strengths: 300 mg; 450 mg; 150 mg; 600 mg; 300 mg/5 mLMild to moderate renal dysfunction (CrCl 30 to 89 mL/min): Begin with lower doses and titrate slowly; closely monitor serum concentrations and signs/symptoms of lithium toxicity.Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances.The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Although mean steady-state lithium plasma levels showed no essential differences, mean daily lithium doses were significantly lower in the elderly.

Therapeutic drug monitoring/range:-Acute episodes: 0.8 to 1.5 mEq/L, not to exceed 2 mEq/L-Long-term control: 0.6 to 1.2 mEq/L-Patients who are abnormally sensitive may exhibit toxicity at concentrations of 1 to 1.5 mEq/L.

Dose adjusted according to serum-lithium concentration, doses are initially divided throughout the day, but once daily administration is preferred when serum-lithium concentration stabilised. The authors concluded that treatment with lithium was highly effective in elderly patients and recommended a low dose regime with frequent monitoring of plasma levels.

Dose Adjustments. The ratio of weight-related lithium dose to plasma level showed a 36% decline with age (0.58, 0.46 and 0.37 1/kg, P < 0.0001, analysis of variance). The purpose of this study was to compare the clinical characteristics of patients starting lithium treatment before (N = 79) or after (N = 31) the age of 65 years. Recent observational studies have focused on lithium treatment in the elderly, with particular reference to safety in terms of thyroid and renal functions.

Although mean steady-state lithium plasma levels showed no essential differences, mean daily lithium doses were significantly lower in the elderly. The search identified 38 cases of lithium toxicity in older adults with a mean age of 71.4 years (SD = 5.53). Lithium level found to be 1.69mmol/L.

Lithium dosage was examined in 3 age groups (⩽ 45 years, 46–64 years, ⩾ 65 years) of 78 inpatients, matched on relevant variables.

Elderly or patients less than 50kg: initially 200–400 mg daily, increasing to 800-1800mg/day. The patient has developed intoxication during maintenance therapy with a lithium dosage which had been unchanged for months. Although mean steady-state lithium plasma levels showed no essential differences, mean daily lithium doses were significantly lower in the elderly.
