Overdose with valsartan may result in marked hypotension, which could lead to depressed level of consciousness, circulatory collapse and/or shock. If the ingestion is recent, vomiting should be induced. Otherwise, the usual treatment would be i.v. infusion of normal saline solution.
Valsartan cannot be eliminated by means of hemodialysis because of its strong plasma binding behavior, whereas clearance of hydrochlorothiazide will be achieved by dialysis.
