Memantine should be used with caution in patients with severe hepatic impairment and a dosage reduction is recommended. No dosage adjustment is needed in patients with mild or moderate hepatic impairment.

Memantine renal clearance involves active tubular secretion moderated by pH dependent tubular reabsorption and conditions that raise urine pH may increase the plasma levels of memantine. Therapy with memantine should be used cautiously in patients with conditions that raise urine pH, such as renal tubular acidosis or severe infections of the urinary tract. Additionally, memantine should be used with caution in patients with severe renal impairment and a dosage reduction is recommended. No dosage adjustment is needed in patients with mild or moderate renal impairment.
