Desmopressin (often called DDAVP) is a medicine that helps your body hold on to water and, in some cases, boosts clotting. Doctors prescribe it for conditions like central diabetes insipidus (where you make too much urine), bedwetting at night, and some mild bleeding problems such as certain cases of hemophilia A or von Willebrand disease before procedures.
Desmopressin comes as tablets, a nasal spray, and injections. Dosing depends on why you're taking it. For bedwetting, doctors often start with a low oral dose at bedtime and increase only if needed. For diabetes insipidus or bleeding issues, the type and frequency vary more and your provider will give specific instructions. Don’t try to convert between spray, tablet, and injection on your own — follow the exact form and dose your prescriber gives you.
One clear rule that helps prevent trouble: restrict fluids around the time you take desmopressin. That reduces the risk of low sodium, which is the most common serious side effect.
The most important risk with desmopressin is hyponatremia — low blood sodium. Symptoms include headache, nausea, confusion, weakness, and in severe cases, seizures. Older adults and people on medicines that affect sodium balance (like thiazide diuretics or some antidepressants) have higher risk.
Other common effects are a mild headache, flushing, or nasal irritation with the spray. If you notice swelling, sudden weight gain, or shortness of breath, tell your doctor — those can signal fluid overload or heart issues.
Your doctor may check your sodium level before and during treatment, especially when starting therapy or after dose changes. If you have low sodium already, heart failure, or uncontrolled high blood pressure, desmopressin may not be right for you.
Interactions matter. Drugs that raise the chance of low sodium (certain antidepressants, antipsychotics, and diuretics) or medicines that change fluid balance can increase risk. Always give your prescriber a full list of current medicines and supplements.
Storage is straightforward: keep tablets, spray, and injections at the recommended temperature and away from kids and pets. Desmopressin is prescription-only — don’t use leftover supplies or someone else’s medication.
If you have questions about whether desmopressin is right for you, or how to take it safely, call your healthcare provider. They can explain dosing for your situation and arrange any needed blood tests. If you're buying online, use a licensed pharmacy and make sure a real prescription is required.
