What is Romazicon?
Romazicon reverses the effects of benzodiazepine (BENZ-oh-dye-AYZ-e-peen) sedatives such as Valium, Versed, Xanax, Tranxene, and others. Benzodiazepines are sometimes used as sedatives before surgery or other medical procedures.
Romazicon is used to reverse benzodiazepine sedation to help you wake up after your medical procedure. This medicine is also used to treat benzodiazepine overdose in adults.
Romazicon may also be used for purposes not listed in this medication guide.
Romazicon may cause seizures (convulsions), especially in people who have sedative-addiction withdrawal symptoms or recent antidepressant overdose, people who have recently received injectable benzodiazepines, or people who had symptoms of a seizure just before receiving this medicine. Talk to your doctor if you have concerns about the risk of seizure.
Before taking this medicine
Romazicon may cause seizures (convulsions), especially:
in people withdrawing from sedative addiction;
in people who have recently taken an antidepressant overdose;
in people who have recently received injectable benzodiazepines; or

Talk to your doctor if you have concerns about the risk of seizure.
You should not receive this medication if you are allergic to Romazicon or any type of benzodiazepine sedative, or if you have taken an overdose of certain antidepressant medication.
To make sure Romazicon is safe for you, tell your doctor if you have:

How is Romazicon given?
Romazicon is injected into a vein through an IV. A healthcare provider will give you this injection.
Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when Romazicon is injected.
Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely after you receive Romazicon.
You may have temporary amnesia while you are waking up from sedation. You may not remember everything going on around you for up to 2 hours.
What happens if I miss a dose?
Because you will receive Romazicon in a clinical setting, you are not likely to miss a dose.
What happens if I overdose?
Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
What should I avoid after receiving Romazicon?
This medication may impair your thinking or reactions. For at least 24 hours after you leave the hospital or surgery center, do not drive or do anything else that requires you to be awake and alert. Continue to limit these activities until you no longer feel sedated (weak, drowsy, or dizzy).
Do not drink alcohol for at least 24 hours after receiving Romazicon, or if you still feel sedated.
Also avoid taking any over-the-counter medications for at least 24 hours, especially if you still feel sedated after receiving Romazicon.
Even though you may feel alert after waking up from sedation, your judgment or reactions may still be impaired. Follow your caregivers' instructions about how long to limit your activities.
