DDAVP oral 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 DDAVP oral

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 he or she 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 immediately. Your treatment will need to be adjusted. (See also Side Effects and Precautions sections.)

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.

DDAVP oral Side Effects

Headache, nausea, upset stomach, or flushing of the face may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Desmopressin can infrequently cause a low level of sodium in the blood, which can be serious and possibly life-threatening. Drinking too much water or other fluids increases the risk of having a low level of sodium in the blood. Therefore, follow your doctor's directions for limiting fluids. Seek immediate medical attention if you have any of these unlikely but serious symptoms of a low level of sodium in the blood: loss of appetite, severe nausea, vomiting, severe headache, muscle weakness/spasms/cramps, sudden weight gain, unusual tiredness, unusual severe drowsiness, mental/mood changes (such as confusion, hallucinations, irritability), loss of consciousness, seizures, slow/shallow breathing.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

DDAVP oral Precautions

Before taking desmopressin, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: kidney disease, a low level of sodium in the blood (current or past hyponatremia).

Before using this medication, tell your doctor or pharmacist your medical history, especially of: high blood pressure, heart disease (such as blocked blood vessels in the heart), conditions that may increase your risk of fluid/mineral imbalance (such as cystic fibrosis, heart failure), the urge to drink too much water without being thirsty, bleeding/clotting problems.

If you have lost too much body water (become dehydrated), your doctor will correct that condition first before starting treatment with desmopressin.

Limit alcohol because it can interfere with how well desmopressin works.

Tell the doctor immediately if you develop any illness that can cause water/mineral imbalance (including fever, diarrhea, vomiting, infections such as the flu) or if you experience conditions that require drinking more fluids (for example, exposure to very hot weather, strenuous exercise, persistent sweating). The doctor may need to stop or adjust desmopressin treatment, especially in children and older adults.

Children may be more sensitive to the side effects of this drug, especially water/mineral imbalance and a low level of sodium in the blood.

Kidney function declines as you grow older. This medication is removed by the kidneys. Therefore, older adults may be at greater risk for water/mineral imbalance and a low level of sodium in the blood while using this drug.

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

It is not known whether this drug passes into breast milk. Consult your doctor before breast-feeding.

Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Other medications besides desmopressin may also affect the balance of water and sodium in your body. Therefore, tell your doctor or pharmacist about all the products you take, including: narcotic pain relievers (such as morphine), nonsteroidal anti-inflammatory drugs (NSAIDs such as ibuprofen, naproxen), psychiatric medicines (such as chlorpromazine), drugs to treat seizures (such as carbamazepine), SSRI antidepressants (such as sertraline), tolvaptan, tricyclic antidepressants (such as amitriptyline), "water pills" (diuretics such as furosemide).
