Problem: When taking desmopressin, a person with diabetes insipidus should always have access to water, keep an eye out for symptoms of dehydration, such as lightheadedness or confusion, closely adhere to their medication schedule, modify their dosage of desmopressin as necessary while ill, and see their doctor if their symptoms worsen, particularly if they include fever, vomiting, or diarrhea. In certain situations, a low-sodium diet may also be advised. Serious thirst, excessive urination, confusion, nausea, vomiting, muscle cramps, unusual fatigue, or significant changes in urine output are all signs of a potential complication, such as hyponatremia from the medication's overhydration. If someone with diabetes insipidus experiences any of these side effects while taking desmopressin, they should contact their doctor right away and may even need emergency care. Need Assignment Help?
