Dexmedetomidine (Intravenous)

Dexmedetomidine injection is used to help you sleep (sedate) before or during surgery or other medical procedures. This medicine is also used to sedate intubated and mechanically ventilated patients during treatment in the intensive care unit (ICU).

This medicine is to be given only by or under the direct supervision of your doctor.

It is very important that your doctor check your progress closely while you are receiving this medicine to make sure it is working properly and to check for unwanted effects.

This medicine may cause hypotension (low blood pressure). Check with your doctor right away if you have blurred vision, confusion, dizziness, faintness, or lightheadedness when getting up suddenly from lying or sitting, sweating, or unusual tiredness or weakness.

Check with your doctor right away if you have chest pain or discomfort, lightheadedness, dizziness, or fainting, slow or irregular heartbeat, trouble breathing, or unusual tiredness. These may be symptoms of bradycardia (slow heartbeat).

This medicine may cause hyperthermia (high body temperature). Check with your doctor right away if you have dizziness, fast, shallow breathing, fast, weak heartbeat, muscle cramps, pale, clammy skin, thirst, or extremely high fever or body temperature.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

In deciding to use a medicine, the chances of taking the medication must be weighed against the beneficial it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your clinician if you have ever had any unusual or allergic reaction to this medicine or any other drugs. Additionally inform your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of dexmedetomidine injection in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of dexmedetomidine injection in the elderly. Nevertheless, elderly patients are more likely to have severe unwanted effects (eg, low blood pressure, slow heartbeat), which may require caution and an adjustment in the dose for patients receiving this medicine.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this drug during breastfeeding. Weigh the potential benefits against the potential chances prior to using this drug while breastfeeding.
