Vasopressin, ADH injection
What is vasopressin injection?
VASOPRESSIN (antidiuretic hormone [ADH] ) is a hormone that is normally produced by the pituitary
gland. Vasopressin helps to keep a regular balance of salts in the blood and to
control the amount and frequency of urination. Without vasopressin too much
water is lost in the urine. Vasopressin helps to prevent or control frequent
urination, excessive thirst, and dehydration associated with diabetes insipidus. Vasopressin cannot be given by mouth because it
is destroyed in the stomach. Generic vasopressin injections are available.
What should I tell my health care
provider before I take this medicine?
They need to know if you have any of these conditions:
blood vessel disease
an unusual or allergic reaction to vasopressin, other medicines, foods,
dyes, or preservatives
pregnant or trying to get pregnant
How should I use this medicine?
Vasopressin is for injection into a muscle, or under the skin. If you have been
instructed to give yourself vasopressin injections, make sure that you
understand how to prepare and inject the dose. Use exactly as directed. Do not
exceed the prescribed dose, and do not use more or less often than prescribed.
In some cases vasopressin may be injected into a vein by means of a slow
infusion pump. This keeps a steady flow of vasopressin into the body.
Contact your pediatrician or health care professional regarding the use of this
medicine in children. Special care may be needed.
What if I miss a dose?
If you use two or more doses per day, use the missed dose as soon as you
remember. If it is nearly time for the next dose, skip the missed dose and
resume your regular schedule with the next dose. Do not use double doses.
If you use one dose per day, use the missed dose as soon as you remember on the
day the dose was due. If you do not remember until the next day, skip the
missed dose and resume your regular schedule with the next dose. Do not use
What drug(s) may interact with
medicines for mental depression
Tell your prescriber or health care professional: about all other medicines you
are taking including non-prescription medicines; if you are a frequent user of
drinks with caffeine or alcohol; if you smoke; or if you use illegal drugs.
These can affect the way your medicine works. Check with your health care
professional before stopping or starting any of your medicines.
What side effects might I notice
from receiving vasopressin?
Side effects that you should report to your prescriber or health care
professional as soon as possible:
difficulty breathing, wheezing
difficulty passing urine
pain, redness, irritation, or swelling at the injection site
rapid weight gain
severe or continuing headaches
skin rash, itching (hives)
Side effects that usually do not require medical attention (report to your
prescriber or health care professional if they continue or are bothersome):
belching, stomach gas
dizziness or fainting
flushing, reddening of the skin
pale area around the mouth
stomach pain or cramps
uterine cramps, or vaginal pain
Drinking 1 or 2 glasses of water when the hormone is injected may prevent or
reduce some side effects. However, vasopressin prevents the loss of water. Too
much water in the body dilutes normal body fluids and can cause confusion,
drowsiness, or lethargy, which may lead to seizures or coma. The risk of too
much water in the body is greater in young children and the elderly. Ask your
prescriber or health care professional for advice about your fluid intake.
