American Regent have recalled another of their injectable medications, vasopressin. This is because there is not enough of the active drug in the injection.
Vasopressin is used to treat and prevent post-operative abdominal distention, during abdominal roentgenography and in diabetes insipidus. Abdominal roentgenography is X-ray photography of the abdomen and the vasopressin is used to dispel gas shadows.
Diabetes insipidus occurs when the body can no longer regulate its own water supply. Normally when the body becomes too low on water the hormone vasopressin is released to tell the kidneys to stop producing urine. In diabetes insipidus this hormone doesn’t tell the body to stop producing urine and allows too much water to be passed from the body, causing excessive urination and dehydration.
Symptoms of diabetes insipidus are: needing to pass large amounts of urine, very frequently (as often as every 15 minutes), feeling constantly thirsty, sleeping difficulties and tiredness resulting from interruption of sleep due to excessive urination and feeling unwell.
Children may also cry, have a raised temperature and fail to gain weight. Older children may wet the bed when they have previously been toilet trained.
Some people with mild diabetes insipidus can manage their condition just by drinking lots of water during the day. In more severe cases, a manufactured version of the hormone vasopressin is given via injection. It is also available as a nasal spray.
