DDAVP

DDAVP is primarily prescribed for the following purposes:

1. Diabetes insipidus: DDAVP is commonly used to manage central diabetes insipidus, a condition characterized by excessive thirst and frequent urination due to a deficiency of vasopressin. It helps reduce urine output and control excessive thirst in individuals with this condition.
2. Bedwetting: Medicine is also used to treat primary nocturnal enuresis, a condition where individuals, usually children, experience bedwetting during sleep. It helps regulate urine production, allowing individuals to have a dry night.
3. Hemophilia and von Willebrand disease: DDAVP is sometimes prescribed to individuals with mild forms of hemophilia A or von Willebrand disease to promote the release of von Willebrand factor and factor VIII, which are involved in blood clotting.

Drug is available in various forms, including tablets, nasal spray, and injection. The specific dosage and administration instructions will vary depending on the condition being treated and individual factors.

Here are general guidelines for using DDAVP in its commonly available forms:

• Keep the other nostril closed using your finger.
• Press down on the spray bottle to release the spray, while breathing gently through your nose.
• Repeat the process for the other nostril if instructed to do so.
• After using the nasal spray, wipe the tip with a clean tissue and replace the protective cap.

Water intoxication or hyponatremia (low sodium levels in the blood):

• Symptoms may include headache, nausea, vomiting, confusion, seizures, muscle weakness, restlessness, and, in severe cases, potentially life-threatening complications.

Prompt medical attention is crucial in cases of DDAVP overdose.

While waiting for medical help, do not induce vomiting. It is important to provide accurate information about the amount of DDAVP taken and the timing of the overdose to the medical professionals assisting you.

Missed Doses

If you miss a dose of DDAVP, take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and resume your regular dosing schedule. Do not take a double dose to make up for the missed one.

If you frequently forget to take your doses or have difficulty adhering to the schedule, it may be helpful to set reminders or use other strategies to help you remember.
