IMPORTANT SAFETY INFORMATION
Naltrexone + Topiramate + Vitamin B12 can cause serious side effects, including:
  • Risk of opioid overdose. You can accidentally overdose in two ways.
    • Naltrexone + Topiramate + Vitamin B12 blocks the effects of opioids, such as heroin or opioid pain medicines, examples include, but are not limited to; morphine (MS Contin®), hydrocodone (Vicodin®), oxycodone (Oxycontin®), hydromorphone (Percocet®), codeine, or tramadol. Do not try to overcome this blocking effect by taking large amounts of opioids—this can lead to serious injury, coma, or death.
    • After you receive a dose of Naltrexone + Topiramate + Vitamin B12, its blocking effect slowly decreases and completely goes away over time. If you have used opioid street drugs or opioid-containing medicines in the past, using opioids in amounts that you used before treatment with Naltrexone + Topiramate + Vitamin B12 can lead to overdose and death. You may also be more sensitive to the effects of lower amounts of opioids:
      • after you have gone through detoxification
      • when your next Naltrexone + Topiramate + Vitamin B12 dose is due
      • if you miss a dose of Naltrexone + Topiramate + Vitamin B12
      • after you stop Naltrexone + Topiramate + Vitamin B12 treatment
Tell your family and the people closest to you of this increased sensitivity to opioids and the risk of overdose.
Talk to your healthcare provider about naloxone, a medicine that is available to patients for the emergency treatment of an opioid overdose. Call 911 or get emergency medical help right away in all cases of known or suspected opioid overdose, even if naloxone is administered.
