All About Nocdurna s Dosage

Medically reviewed by Brittany A. Duke, PharmD, RPh — By Carla Eisenstein, PharmD on October 19, 2022

Introduction

If you have a certain kind of urinary frequency, your doctor might suggest Nocdurna as a treatment option for you. It’s a prescription drug used in adults to treat nocturia (frequent urination at night) that wakes you up two or more times nightly. Nocdurna comes as a sublingual tablet, which means you dissolve it under your tongue. It contains the active ingredient desmopressin acetate. (An active ingredient is what makes a drug work.) Nocdurna is a hormone and belongs to a group of drugs called antidiuretics, which help stop excess urination. This article describes the dosages of Nocdurna, as well as its strengths and how to take it. To learn more about Nocdurna, see this in-depth article. Note: This article covers Nocdurna’s usual dosages, which are provided by the drugmaker. But when using Nocdurna, always take the dosage your doctor prescribes.

Dosage adjustments

Your doctor may pause your dose temporarily if there are abnormal levels of sodium (salt) in your blood. Talk with your doctor about how often you’ll need blood tests during your Nocdurna treatment. If you have decreased kidney function or are ages 65 years and above, your doctor may choose a different treatment for your condition. Talk with them about whether Nocdurna is safe for you.

No, Nocdurna’s dosage is not based on weight. Nocdurna has one dose for males* and another for females*. The difference in dosage is based on research that showed the risk of hyponatremia (low blood sodium levels) was greater in females who took a higher dose. (See the boxed warning at the beginning of this article.) * In this article, we use the terms “male” and “female” to refer to someone’s sex assigned at birth.

Is Nocdurna used for anxiety If so what s the dosage

No, Nocdurna is not used for anxiety. If you feel anxious when going to sleep because you expect to wake up to urinate, that’s understandable. If that’s a main cause of your anxiety, Nocdurna may help since it’s used to treat frequent nighttime urination. If you experience anxiety from other causes, talk with your doctor about available treatment options.

How long does it take for my Nocdurna dose to start working

Nocdurna takes about half an hour to start working, which is why you take it an hour before going to bed.

How is Nocdurna taken

The usual Nocdurna dosing frequency is once per day. An hour before you go to sleep, remove the Nocdurna tablet from the blister pack and place it under your tongue. Let it dissolve completely. (Nocdurna is usually taken without water.) You’ll want to limit how much liquid you drink from about 1 hour before taking Nocdurna to 8 hours after. This helps the drug work and also helps you avoid side effects like hyponatremia (low blood sodium levels). You’ll also likely be instructed to urinate right before you go to sleep. For information on the expiration, storage, and disposal of Nocdurna, see this article.

Accessible drug containers and labels

If you find it hard to read the prescription label on your medication, tell your doctor or pharmacist. Some pharmacies provide medication labels that:have large print or use braillefeature a code you can scan with a smartphone to change the text to audio Your doctor or pharmacist may be able to recommend pharmacies that offer these accessibility features if your current pharmacy doesn’t. If you have trouble opening the blister pack, let your pharmacist know. They may have tips to help make it simpler to open the drug’s container.

What factors can affect my dosage

The dosage of Nocdurna you’re prescribed may depend on several factors. These include:the type and severity of the condition you’re using the drug to treatyour ageyour blood sodium levelswhether you’re male* or female*other conditions you may have (see “Dosage adjustments” above) * In this article, we use the terms “male” and “female” to refer to someone’s sex assigned at birth. For information about the difference between sex and gender, see this article.

What if I miss a dose

If you miss a dose but haven’t yet gone to bed, you can still take it. If you miss a dose and don’t realize it until the next day, just take your next dose at the usual time. Do not take two doses at once. If you need help remembering to take your dose of Nocdurna on time, try using a medication reminder. This can include setting an alarm or downloading a reminder app on your phone.

What should be done in case of overdose

Do not take more Nocdurna than your doctor prescribes as this can lead to serious side effects.
