Recommended Action
      Management If medically feasible, antihypertensive medications should be interrupted 24 hours prior to amifostine administration. Blood pressure should be closely monitored during and after treatment. In addition to hypotension, transient hypertension or exacerbation of preexisting hypertension may occur from intravenous hydration, discontinuation of antihypertensive medications, or other causes. Patients who continue their hypotensive medication(s) during amifostine therapy should be carefully monitored for the development of hypotension.
