Vasopressin tablets: Vasopressin Uses, Side Effects & Warnings

Diabetes insipidus – Treatment – NHS

Treatments for diabetes insipidus aim to reduce the amount of urine your body produces.

Depending on the type of diabetes insipidus you have, there are several ways of treating your condition and controlling your symptoms.

Cranial diabetes insipidus

Mild cranial diabetes insipidus may not require any medical treatment.

Cranial diabetes insipidus is considered mild if you produce approximately 3 to 4 litres of urine over 24 hours.

If this is the case, you may be able to ease your symptoms by increasing the amount of water you drink to avoid dehydration.

Your GP or endocrinologist (a specialist in hormone conditions) may advise you to drink a certain amount of water every day, usually at least 2.5 litres.

But if you have more severe cranial diabetes insipidus, drinking water may not be enough to control your symptoms.

As your condition is caused by a shortage of vasopressin (AVP), your GP or endocrinologist may prescribe a treatment that takes the place of AVP, known as desmopressin.

Desmopressin

Desmopressin is a manufactured version of AVP that’s more powerful and more resistant to being broken down than the AVP naturally produced by your body.

It works just like natural AVP, stopping your kidneys producing urine when the level of water in your body is low.

Desmopressin can be taken as a nasal spray, in tablet form or as a form that melts in your mouth, between your gum and your lip.

If you’re prescribed desmopressin as a nasal spray, you’ll need to spray it inside your nose once or twice a day, where it’s quickly absorbed into your bloodstream.

If you’re prescribed desmopressin tablets, you may need to take them more than twice a day.

This is because desmopressin is absorbed into your blood less effectively through your stomach than through your nasal passages, so you need to take more to have the same effect.

Your GP or endocrinologist may suggest switching your treatment to tablets if you develop a cold that prevents you using the nasal spray.

Desmopressin is very safe to use and has few side effects.

But possible side effects can include:

  • headache
  • stomach pain
  • feeling sick
  • a blocked or runny nose
  • nosebleeds

If you take too much desmopressin or drink too much fluid while taking it, it can cause your body to retain too much water.

This can result in:

  • headaches
  • dizziness
  • feeling bloated
  • hyponatraemia – a low level of sodium (salt) in your blood

Symptoms of hyponatraemia include:

  • a severe or prolonged headache
  • confusion
  • feeling sick (nausea) and vomiting

If you think you may have hyponatraemia, stop taking desmopressin immediately and call your GP for advice.

If this is not possible, go to your local A&E department.

Nephrogenic diabetes insipidus

If you have nephrogenic diabetes insipidus that’s caused by taking a particular medication, such as lithium or tetracycline, your GP or endocrinologist may stop your treatment and suggest an alternative medication.

But do not stop taking it unless you have been advised to by a healthcare professional.

As nephrogenic diabetes insipidus is caused by your kidneys not responding to AVP, rather than a shortage of AVP, it usually cannot be treated with desmopressin.

But it’s still important to drink plenty of water to avoid dehydration.

If your condition is mild, your GP or endocrinologist may suggest reducing the amount of salt and protein in your diet, which will help your kidneys produce less urine.

This may mean eating less salt and protein-rich food, such as processed foods, meat, eggs and nuts.

Do not alter your diet without first seeking medical advice.

Your GP or endocrinologist will be able to advise you about which foods to cut down on.

Find out more about eating a healthy, balanced diet.

If you have more severe nephrogenic diabetes insipidus, you may be prescribed a combination of thiazide diuretics and a non-steroidal anti-inflammatory drug (NSAID) to help reduce the amount of urine your kidneys produce. 

Thiazide diuretics

Thiazide diuretics can reduce the rate the kidneys filter blood, which reduces the amount of urine passed from the body over time.

Side effects are uncommon, but include:

  • dizziness when standing
  • indigestion
  • very sensitive skin
  • erectile dysfunction (impotence) in men 

This last side effect is usually temporary and should resolve itself if you stop taking the medication.

Non-steroidal anti-inflammatory drugs (NSAIDs)

Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, help reduce urine volume further when they’re used in combination with thiazide diuretics.

But long-term use of NSAIDs increases your risk of developing a stomach ulcer.

To counter this increased risk, an additional medication called a proton pump inhibitor (PPI) may be prescribed.

PPIs help protect your stomach lining against the harmful effects of NSAIDs, reducing the risk of ulcers forming.

Help with health costs

If you have diabetes insipidus, you do not have to pay prescription charges for desmopressin.

You’ll need to fill in a medical exemption (MedEx) certificate to qualify.

See who can get free prescriptions for more information about how to apply for a MedEx certificate.

You may have to pay for other medicines that may be required on a short-term basis, such as thiazide diuretics.

Desmopressin Oral: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing

Warnings:

Desmopressin can rarely cause a low level of sodium in the blood (hyponatremia), which can be serious or even fatal. Drinking too much liquid, using certain medications (such as “water pills”/diuretics including furosemide, glucocorticoids such as prednisone), being 65 years or older, or having certain medical conditions may increase the risk of low sodium in the blood. Lab tests (such as urine tests, sodium blood levels) must be done before you start using this medication and while you are using it. Keep all medical and lab appointments.

Tell your doctor right away if you develop symptoms of low sodium in the blood, such as nausea, vomiting, headache, muscle weakness/cramps, unusual tiredness, unusual drowsiness, dizziness, restlessness, mental/mood changes including confusion/irritability.

Get medical help right away if you have any very serious side effects, including seizure or trouble breathing.

Uses

Desmopressin is used to control the amount of urine your kidneys make. Normally, the amount of urine you make is controlled by a certain substance in the body called vasopressin. In people who have “water diabetes” (diabetes insipidus) or certain kinds of head injury or brain surgery, the body does not make enough vasopressin. Desmopressin is a man-made form of vasopressin and is used to replace a low level of vasopressin. This medication helps to control increased thirst and too much urination due to these conditions, and helps prevent dehydration.Desmopressin is also used to control nighttime bedwetting in children. It reduces how often your child urinates and decreases the number of bedwetting episodes.

How to use Desmopressin ACETATE

For the treatment of diabetes insipidus, take this medication by mouth, usually 2 to 3 times a day or as directed by your doctor.

For the treatment of bedwetting, take this medication by mouth, usually once a day at bedtime. Children should limit the fluids they drink after dinner, especially 1 hour before the desmopressin dose until the next morning, or at least 8 hours after the dose. If your child wakes up during the night, limit the amount that your child drinks.

All patients taking desmopressin, especially children and older adults, must limit drinking of water and other fluids. Consult your doctor for details. If you find that you are drinking more fluids than directed, tell your doctor right away. Your treatment will need to be adjusted.

Dosage is based on your medical condition and response to treatment. Do not take more desmopressin or take it more often than prescribed.

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.

Tell your doctor if your condition does not improve or if this medication stops working well.

Side Effects

Pharmacological action

Vasopressin has antidiuretic and vasopressor effects.

Pharmacodynamics

Vasopressin interacts with V- and Vi-receptors, which are located on vascular smooth muscle cells, thus regulating vasoconstriction. There is an increase in the permeability of the epithelium of the collecting duct for water located in the kidneys and an increase in the process of fluid reabsorption. The substance causes an increase in the volume of blood circulating in the body, hyponatremia and a decrease in osmolarity.

Vasopressin is able to increase the tone of the smooth muscles of internal organs, in particular the gastrointestinal tract, by interacting with V1a receptors. This leads to an increase in vascular tone and an increase in peripheral vascular resistance. Blood pressure rises (the medicine narrows the arterioles). Vasopressin has a hemostatic effect, spasms small vessels and capillaries, affects the von Willebrand coagulation factor, and stimulates platelet aggregation.

Vasopressin also affects the central nervous system, takes part in the regulation of aggression and the process of memorization. Studies have been conducted on the use of vasopressin in mice – prairie voles. In the course of these studies, by acting on vasopressin receptors in the brains of animals, mice were able to be made monogamous, faithful to one partner. Thus, it was possible to prove that vasopressin (its AVPR1A) is responsible for the social behavior of animals, finding a partner and the formation of a paternal instinct in males.

Synthetic hormone preparations are administered parenterally.

Pharmacokinetics

With injection or intranasal administration of vasopressin, the half-life (T ½ ) is about 20 minutes. The metabolism of vasopressin occurs in the tissues of the liver and kidneys, where disulfide bonds are restored and further cleavage of peptides occurs. A small amount of vasopressin is excreted unchanged in the urine.
