Hydroxyzine (Intramuscular)

Overview

Hydroxyzine injections are administered by a doctor or other medical professional; cases of self-administration are very rare. In most cases, this medication is used to relax the patient prior to surgery or another medical procedure and encourages sleep. It is often used in dental settings as well. The drug can also be administered following an operation to help aid the recovery process. This medication is also an effective treatment of allergic reactions that are associated with chronic urticaria and asthma.

Patients will typically receive this medication while in the hospital or another clinic-like setting and any significant symptoms that are experienced by the patient should be immediately reported to the medical team. It is strongly advised that the patient remains at the hospital until all effects of the drug have dissipated as hydroxyzine has been reported to cause extreme dizziness and drowsiness. Do not drive after receiving this injection as it may make it unsafe for you to operate an automobile.

This medication is an antihistamine that blocks the production of histamine thereby relieving many symptoms caused by common allergies. Other uses include controlling the anxiety experienced by patients with certain types of heart disease, lessening withdrawal symptoms that occur during alcohol detox, and counteracting vomiting and nausea. If you have received this medication it is important that all other CNS depressing medications are avoided. If you are currently taking other antihistamines, cold remedies, or sleep aids be sure to discuss this usage with your doctor prior to the administration of the hydroxyzine injection.
