Vigil computes Hydroxyzine for your patient's actual weight — and adjusts for renal or hepatic impairment automatically, with the cited rationale. The number is calculated from a verified database, never guessed.

Decision support for licensed clinicians — not a substitute for clinical judgment. Always verify against the package insert and the patient in front of you.
