How is vasopressin given (Pitressin)?
Vasopressin is given as an injection under the skin or into a muscle. You will receive this injection in a clinic or hospital setting. Vasopressin is usually given as needed every 3 to 4 hours. The time interval between doses will depend on how your body responds to the medication.
To treat diabetes insipidus, vasopressin is sometimes given into the nose by nasal spray or medicine dropper, or insertion of a cotton pad that has been soaked in vasopressin.
When used for abdominal x-ray, vasopressin injections are usually given at 2 hours before and 30 minutes before your x-ray. Your doctor may also recommend you receive an enema before you receive your first dose of vasopressin.
Vasopressin can cause temporary side effects such as nausea, stomach pain, or "blanching" of your skin (such as pale spots when you press on the skin). Drinking 1 or 2 glasses of water each time you receive an injection may help ease these side effects.
Follow your doctor's instructions about the type and amount of liquids you should drink during your treatment with vasopressin. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
To be sure this medication is not causing harmful effects, your blood will need to be tested on a regular basis. You heart function may also need to be tested.
