Vasopressins are used to treat diabetes insipidus, bedwetting, and managing certain types of bleeding. They work by mimicking the action of the natural hormone vasopressin, which helps your kidneys manage the amount of water in your body. These medications come in different forms, including oral tablets, nasal sprays, and injections. Examples include desmopressin (DDAVP) and terlipressin (Terlivaz). You can choose the form that best fits your needs.
