What is the half-life of Vasopressin (AVP / ADH)?

Vasopressin (AVP / ADH) has an approximate elimination half-life of 12 min. Very short-acting — protocols dose 1–2× a day.

How long does Vasopressin (AVP / ADH) stay in your system?

Roughly 97% of a dose has cleared after five half-lives — about ~1 h for Vasopressin (AVP / ADH). That is the window that matters for washouts, bloodwork and surgery.

How is Vasopressin (AVP / ADH) taken?

Vasopressin (AVP / ADH) is typically administered by the subcutaneous route. Research range: ~1 IU intranasal as needed; medical dosing varies widely.

What are the risks of Vasopressin (AVP / ADH)?

Risk of water intoxication / low sodium (hyponatremia) Raises blood pressure; caution with cardiovascular disease Prescription-only; clinician supervision
