What PITRESSIN is used for
PITRESSIN is a medicine that contains argipressin, or antidiuretic hormone. Argipressin is normally produced by the pituitary gland.
Argipressin acts on blood vessels and the kidney and reduces the amount of fluids you pass in the urine. Argipressin also causes muscles called ”smooth muscles” to contract.
If your body does not produce enough argipressin you can get a condition called “diabetes insipidus”.
PITRESSIN is used to treat deficiency of argipressin in this disorder. Symptoms of diabetes insipidus include passing large volumes of pale urine and feeling extremely thirsty. Diabetes insipidus is not the same as diabetes mellitus where sugar is passed in the urine.
Argipressin can also be used by your doctor to relieve stomach bloating after you have had surgery or an X-ray procedure of the abdomen.
Ask your doctor if you have any questions why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason. There is no evidence that PITRESSIN is addictive.
This medicine is available only with a doctor’s prescription.
