Study Notes
Desmopressin Overview
- Desmopressin (D AVP, Stimate) is an antidiuretic hormone replacement and a vasopressin analog.
- It is a synthetic analog of human antidiuretic hormone (ADH) used to control acute symptoms of diabetes insipidus (DI).
Route of Administration
- Desmopressin is primarily administered orally, but can also be given intravenously (IV) and via parental routes.
Duration of Action
- The duration of action for Desmopressin is approximately 20 hours.
IV Administration Guidelines
- When administered IV for DI, desmopressin should be given undiluted over a period of 1 minute.
- Dosage must be verified by two nurses to ensure safety.
Post-Administration Monitoring
- Following an IV injection of Desmopressin, fluids should be restricted and monitored to prevent complications.
Drug Interactions
- Nonsteroidal anti-inflammatory drugs (NSAIDs) can enhance the antidiuretic action of Desmopressin.
- Drugs that may reduce the antidiuretic effect include heparin, alcohol, lithium, and epinephrine.
Adverse Effects
- Potentially fatal adverse effects include water intoxication, which can lead to drowsiness, headache, listlessness, convulsions, and coma.
- Other adverse effects may be transient headache, nausea, mild abdominal pain, flushing, hypertension, and pain or swelling at the injection site.
- Intranasal administration may cause congestion, rhinitis, and epistaxis (nosebleeds).
Overdose
- Severe water intoxication is the primary concern in instances of Desmopressin overdose.
Causes of Diabetes Insipidus
- Common causes of diabetes insipidus include brain tumors damaging the hypothalamus or pituitary gland, severe head injuries affecting these areas, and complications arising during brain or pituitary surgery.
Understanding Diabetes Insipidus
- Diabetes insipidus occurs due to low levels of antidiuretic hormone, leading to massive urination (polyuria) and dehydration.
- Hypotension may be a common symptom experienced by individuals with diabetes insipidus.
Post-Correction Monitoring
- After correcting diabetes insipidus, it is important for nurses to monitor for potential hypertension.
