5 Warnings and Precautions

PRECAUTIONS

Geriatric Use

(Newly added subsection)

Clinical studies of HIPREX did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

HIPREX is contraindicated in patients with renal insufficiency and severe hepatic insufficiency.
