Hi,

As you may know, Vivitrol blocks the effects of opioids (narcotics). The effects of the month-long injection are at their optimal for a month, but it takes longer for the drug to clear out of the system, in this case, approximately 5 to 10 days. Besides, the reason you might have needed the Vivitrol, in the first place, might also interfere with the effects of narcotics you might be given during surgery.

Another factor to consider is the type and location of anesthesia you will be getting. Therefore, I suggest you discuss this with your doctor prior to surgery in order to look into other options, such as using non-narcotic drugs for anesthesia or needing to increase the dose of narcotics you will need, and make an informed decision. Wishing you good luck in your surgery and all the best.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Ornela Ademovi
